There was a crash during the distribution installation over PXE using kickstart
by Dotan Barak 17 Feb '09

17 Feb '09

Hi. I configured a remote machine to allow network installation when the machine is being loaded with PXE. I'm using an x86_64 desktop. The installation is almost fully automated with a kickstart file. I enabled PXE in the BIOS, started the installation and in the middle of the installation, i got a crash which reported an error. I opened a bug on this issue: http://bugs.centos.org/view.php?id=3394. Someone, called Tru, kindly gave me the following answer: from your logs: File "/usr/lib/anaconda/iw/progress_gui.py", line 243, in renderCallback self.intf.icw.nextClicked() File "/usr/lib/anaconda/gui.py", line 1045, in handleRenderCallback self.currentWindow.renderCallback() IOError: [Errno 30] Read-only file system ... which was caused by: <4>hda: status timeout: status=0xd0 { Busy } <4>ide: failed opcode was: unknown <3>hda: no DRQ after issuing MULTWRITE_EXT <4>ide0: reset: success <4>hda: status timeout: status=0xd0 { Busy } <4>ide: failed opcode was: unknown <3>hda: no DRQ after issuing MULTWRITE_EXT <4>ide0: reset: success <4>hda: status timeout: status=0xd0 { Busy } <4>ide: failed opcode was: unknown ... <4>ide0: reset: success <4>hda: status timeout: status=0xd0 { Busy } <4>ide: failed opcode was: unknown <4>end_request: I/O error, dev hda, sector 344757 <3>hda: no DRQ after issuing MULTWRITE_EXT <4>hda: status error: status=0x58 { DriveReady SeekComplete DataRequest } <4>ide: failed opcode was: unknown <3>hda: drive not ready for command .... 4>hda: status error: status=0x58 { DriveReady SeekComplete DataRequest } <4>ide: failed opcode was: unknown <3>hda: drive not ready for command <4>ide0: reset: success <3>Aborting journal on device dm-0. <2>ext3_abort called. <2>EXT3-fs error (device dm-0): ext3_journal_start_sb: Detected aborted journal <2>Remounting filesystem read-only Issue History Date Modified Username Field Change ====================================================================== 2009-02-17 11:30dotan_bar New Issue 2009-02-17 11:30dotan_bar File Added: bug_report.txt 2009-02-17 11:34dotan_bar File Added: default.ks 2009-02-17 11:35dotan_bar Note Added: 0008711 2009-02-17 12:20tru Note Added: 0008713 ====================================================================== Reply Forward noreply(a)centos.org to me show details 2:21 PM (1 hour ago) Reply The following issue has been CLOSED ====================================================================== http://bugs.centos.org/view.php?id=3394 ====================================================================== Reported By: dotan_bar Assigned To: ====================================================================== Project: CentOS-5 Issue ID: 3394 Category: -OTHER Reproducibility: unable to reproduce Severity: crash Priority: normal Status: closed Resolution: open Fixed in Version: ====================================================================== Date Submitted: 2009-02-17 11:30 UTC Last Modified: 2009-02-17 12:21 UTC - Show quoted text - ====================================================================== Summary: There was a crash during the distribution installation over PXE using kickstart Description: I configured a remote machine to allow network installation when the machine is being loaded with PXE.

clamAV problem
by Anne Wilson 17 Feb '09

17 Feb '09

Since my power problems that resulted in a re-install I have a problem which I've failed to locate up to now. The logs show daily.cld updated (version: 8950, sigs: 72593, f-level: 38, builder: ccordes) Database updated (510565 signatures) from db.gb.clamav.net (IP: 163.1.3.8) WARNING: Clamd was NOT notified: Can't connect to clamd through /tmp/clamd.socket I've been through the config files, but obviously there is something in the setup that I've failed to do. Scans are running every night, but service clamd status clamd: unrecognized service It has to be something stupid that I've missed. Can someone kick me in the right direction? Thanks Anne

MySql server on Centos 5
by Blaž Bogataj 17 Feb '09

17 Feb '09

I have a question about Mysql. I use mysql 5.0.68 on Centos 4 from Centos plus repository. The old hardware steers me to Centos 5, however there is mysql 5.0.45. Some program solutions which we are using on the old server (production for 500 users) do not work properly on new one (some querys producing reports). Is there a source where I can find version for Centos 5 server equal to the Mysql version which I run on the old server. I'd like to use some kind of repository. Looking forward for sugesstions.

Suggestion for Server Room monitoring
by Fajar Priyanto 17 Feb '09

17 Feb '09

Hi all, I have a situation like this: Our little server room is always on. It has an air conditioning unit, but barely enough. So sometimes during weekend, the temperature could reach unhealthy level, like 29 degree Celsius. Currently, there's no personnel to monitor it 24 hours a day. I'm thinking of using a tool to monitor the temperature, and then send sms/email when it reaches certain threshold. Anyone has an idea? Could be software based or hardware one. Thank you.

ipsec net-to-net problem
by brad＠bradandkim.net 16 Feb '09

16 Feb '09

I am trying to set up an ipsec net-to-net VPN and am having problems. Here is a diagram of the setup: LAN A --> Host A ----> Internet <---- Host B <-- LAN B LAN A = 10.10.2.0/24 LAN A gateway = 10.10.2.254 Host A internal = 10.10.2.254 Host A external = xx.xx.xx.xx Host B external (see below) Host B internal = 10.10.1.10 LAN B = 10.10.1.0/24 LAN B gateway = 10.10.1.252 (F5 Big IP) Host A is CentOS5 and is a router/firewall for LAN A. Host B is RHEL4 and does not have a public IP. It is behind an F5 BigIP and the BigIP forwards all traffic for yy.yy.yy.yy to Host B. Likewise it masks Host B's outbound traffic as yy.yy.yy.yy. I can get this tunnel to come up but seem to be having problems on the Host A side. If I run 'tcpdump |grep -i esp' on Host A and ping a host on LAN A from a host on LAN B (whose routing table was adjusted to go through Host B for the 10.10.2.0 network), I see ESP traffic on Host A: AH(spi=0x04c98137,seq=0x3): IP 10.10.1.10 > xx.xx.xx.xx: ESP(spi=0x07b6bcd3,seq=0x3), length 116 (ipip-proto-4) If I ping a host on LAN B from a host on LAN A I don't see any ESP traffic on either Host A or Host B and the host doing the ping gets a 'Destination Host Unreachable'. It seems like a problem with the routing on Host A. Here is the result of setkey -D on both hosts: Host A: xx.xx.xx.xx yy.yy.yy.yy esp mode=tunnel spi=169285624(0x0a1717f8) reqid=0(0x00000000) E: 3des-cbc ce370c79 68e74da7 79ba58b9 1605f149 f3e98e5b 9984da9b A: hmac-sha1 ea9dba47 cf6a4c04 7e949d4f a8f304f0 76e006c7 seq=0x00000000 replay=4 flags=0x00000000 state=mature created: Feb 16 12:46:01 2009 current: Feb 16 12:47:13 2009 diff: 72(s) hard: 3600(s) soft: 2880(s) last: hard: 0(s) soft: 0(s) current: 0(bytes) hard: 0(bytes) soft: 0(bytes) allocated: 0 hard: 0 soft: 0 sadb_seq=3 pid=5198 refcnt=0 xx.xx.xx.xx yy.yy.yy.yy ah mode=tunnel spi=173186772(0x0a529ed4) reqid=0(0x00000000) A: hmac-sha1 82aaec77 11dfb67c 7fbb7f7c 152c2764 4445ad8e seq=0x00000000 replay=4 flags=0x00000000 state=mature created: Feb 16 12:46:01 2009 current: Feb 16 12:47:13 2009 diff: 72(s) hard: 3600(s) soft: 2880(s) last: hard: 0(s) soft: 0(s) current: 0(bytes) hard: 0(bytes) soft: 0(bytes) allocated: 0 hard: 0 soft: 0 sadb_seq=2 pid=5198 refcnt=0 yy.yy.yy.yy xx.xx.xx.xx esp mode=tunnel spi=166536016(0x09ed2350) reqid=0(0x00000000) E: 3des-cbc b63a5538 c6a2dd3b f449df6e c594cd16 644a59d4 cb45dfef A: hmac-sha1 5d8d015c f8e8e12f d117dc5b fc64d2ed f3ca79b5 seq=0x00000000 replay=4 flags=0x00000000 state=mature created: Feb 16 12:46:01 2009 current: Feb 16 12:47:13 2009 diff: 72(s) hard: 3600(s) soft: 2880(s) last: hard: 0(s) soft: 0(s) current: 0(bytes) hard: 0(bytes) soft: 0(bytes) allocated: 0 hard: 0 soft: 0 sadb_seq=1 pid=5198 refcnt=0 yy.yy.yy.yy xx.xx.xx.xx ah mode=tunnel spi=84103999(0x0503533f) reqid=0(0x00000000) A: hmac-sha1 022dbd45 248b1ffa 05d94068 22e3c530 5485a468 seq=0x00000000 replay=4 flags=0x00000000 state=mature created: Feb 16 12:46:01 2009 current: Feb 16 12:47:13 2009 diff: 72(s) hard: 3600(s) soft: 2880(s) last: hard: 0(s) soft: 0(s) current: 0(bytes) hard: 0(bytes) soft: 0(bytes) allocated: 0 hard: 0 soft: 0 sadb_seq=0 pid=5198 refcnt=0 Host B: xx.xx.xx.xx 10.10.1.10 esp mode=tunnel spi=169285624(0x0a1717f8) reqid=0(0x00000000) E: 3des-cbc ce370c79 68e74da7 79ba58b9 1605f149 f3e98e5b 9984da9b A: hmac-sha1 ea9dba47 cf6a4c04 7e949d4f a8f304f0 76e006c7 seq=0x00000000 replay=4 flags=0x00000000 state=mature created: Feb 16 12:45:57 2009 current: Feb 16 12:47:35 2009 diff: 98(s) hard: 3600(s) soft: 2880(s) last: hard: 0(s) soft: 0(s) current: 0(bytes) hard: 0(bytes) soft: 0(bytes) allocated: 0 hard: 0 soft: 0 sadb_seq=3 pid=15049 refcnt=0 xx.xx.xx.xx 10.10.1.10 ah mode=tunnel spi=173186772(0x0a529ed4) reqid=0(0x00000000) A: hmac-sha1 82aaec77 11dfb67c 7fbb7f7c 152c2764 4445ad8e seq=0x00000000 replay=4 flags=0x00000000 state=mature created: Feb 16 12:45:57 2009 current: Feb 16 12:47:35 2009 diff: 98(s) hard: 3600(s) soft: 2880(s) last: hard: 0(s) soft: 0(s) current: 0(bytes) hard: 0(bytes) soft: 0(bytes) allocated: 0 hard: 0 soft: 0 sadb_seq=2 pid=15049 refcnt=0 10.10.1.10 xx.xx.xx.xx esp mode=tunnel spi=166536016(0x09ed2350) reqid=0(0x00000000) E: 3des-cbc b63a5538 c6a2dd3b f449df6e c594cd16 644a59d4 cb45dfef A: hmac-sha1 5d8d015c f8e8e12f d117dc5b fc64d2ed f3ca79b5 seq=0x00000000 replay=4 flags=0x00000000 state=mature created: Feb 16 12:45:57 2009 current: Feb 16 12:47:35 2009 diff: 98(s) hard: 3600(s) soft: 2880(s) last: hard: 0(s) soft: 0(s) current: 0(bytes) hard: 0(bytes) soft: 0(bytes) allocated: 0 hard: 0 soft: 0 sadb_seq=1 pid=15049 refcnt=0 10.10.1.10 xx.xx.xx.xx ah mode=tunnel spi=84103999(0x0503533f) reqid=0(0x00000000) A: hmac-sha1 022dbd45 248b1ffa 05d94068 22e3c530 5485a468 seq=0x00000000 replay=4 flags=0x00000000 state=mature created: Feb 16 12:45:57 2009 current: Feb 16 12:47:35 2009 diff: 98(s) hard: 3600(s) soft: 2880(s) last: hard: 0(s) soft: 0(s) current: 0(bytes) hard: 0(bytes) soft: 0(bytes) allocated: 0 hard: 0 soft: 0 sadb_seq=0 pid=15049 refcnt=0 Here are the ifcfg-ipsec files for each host.

INIT: Id "snmp" respawning too fast: disabled for 5 minutes
by David Halik 16 Feb '09

16 Feb '09

Hello all, I recently started seeing these messages on the consoles of three production Centos 5.2 servers. They have been occurring nonstop for the past few days and show up routinely every five minutes. INIT: Id "snmp" respawning too fast: disabled for 5 minutes INIT: Id "snmp" respawning too fast: disabled for 5 minutes INIT: Id "snmp" respawning too fast: disabled for 5 minutes Despite trying to debug this and googling for the last couple of hours, I haven't had any luck as to why the errors are generated or how to fix them. There are a ton of posts on the web related to other Id's, such as various tty ports and "x", but I haven't seen a single thing related to "snmp". The answer usually seems to be that there are misconfigured lines in /etc/inittab, but in my case there is nothing even remotely related to "Id snmp" in inittab. The make matters more confusing, snmp isn't installed or being used on these machines. I doubled checked and the extent of any snmp packages are these two: # rpm -qa | grep -i snmp perl-Net-SNMP-5.2.0-1.2.el5.rf net-snmp-libs-5.3.1-24.el5_2.1 Both only contain a couple of libraries, so I hardly believe they have anything to do with it. According to what I've learned, this error is usually generated when init tries to continually respawn a process that dies immediately... but as to what process it could possible be I have no idea. I even tried to strace init (-p1), but apparently this is a forbidden operation: # strace -p1 attach: ptrace(PTRACE_ATTACH, ...): Operation not permitted That's a shame too, but at least I could see what init is trying to do. Any ideas? I'm just about stumped as to how to proceed at this point. Thanks in advance. -- ================================ David Halik System Administrator OIT-CSS Rutgers University dhalik(a)jla.rutgers.edu ================================

logs such as messages, boot.log, and kernel contained 0 size

Hi, My both CentOS 5 servers have logging problems. Logs such as messages, boot.log, kernel, spooler, and tallylog in /var/log directory are all 0 size. The kernel is: Linux 2.6.18-92.1.22.el5 #1 SMP. Since the /var/log/messages contained no information it would be impossible to troubleshoot the problem. I am very sure both systems have not been hacked by others.

funny SMS server tips
by Fajar Priyanto 16 Feb '09

16 Feb '09

Hi guys, Hehe.. I thought I want to share this. In previous email, I said about monitoring server room. I just realize that we have this quite old sms server appliance in the room. It's still running though. I want to setup cronjob from linux machines, to send mail to that sms server, and it will then send sms to my cell about the machine condition. Problem is, nobody knows how to configure the sms server, and there's no docs beside a little description in the web UI. Been googling around few hours, but since it's quite old and proprietary, no good result. Problem is, the sms server's qmail refuses to work if I use hostname in the mail like mycellnum@sms-server. If I want to use mycellnum(a)192.168.1.100, sendmail refuses to send it as "host not found". So, out of curiosity, I define this in this /etc/hosts: 192.168.1.100 192.168.1.100 And now sending from sendmail to mycellnum(a)192.168.1.100 works! is it a feature or what? In network convention, all-numeric hostname is not allowed right? Hehe.. anyway, now I can monitor my server room using sms.

network driver at installation time
by Jerry Geis 16 Feb '09

16 Feb '09

Is there anyway to load a network driver at installation time. Centos 5.2 x86_64. Alternatively, is there a way to do a USB network driver at boot? Either is fine... Presently I have a rtl 8168 that just hangs at DHCP request. I want to use all the kickstart information I have setup, but need the network to work for that. Any ideas? Jerry

tty login hangs
by Stewart Williams 15 Feb '09

15 Feb '09

Hi all, I have two servers both identical in hardware and I have just done a clean install of CentOS 5.2 x86_64 on both. Sometimes (more often than not) when I log in at the physical console (e.g. tty1, tty2, etc.) I will be logged in and it stops responding even if the shell is not doing anything. When this happens I can still switch to another VT with alt+f2 and login as normal. I don't know if bash, mingetty or whatever process is locking up. If I do a `ps ax` all processes are sleeping. Any idea's what could cause this? Thanks

httpd: "internal dummy connection"
by Mike -- EMAIL IGNORED 14 Feb '09

14 Feb '09

On my Centos 2.5 web server, in /var/log/httpd/access_log, I saw several occurrences of: new.mydomain.net - - [11/Feb/2009:14:34:58 -0500] "GET / HTTP/1.0" 403 - "-" "Apache/2.2.3 (CentOS) (internal dummy connection)" I have never seen anything like this before over many years of watching my logs. I presume it failed because my named virtual host does not have "new...", if for no other reason. What is it? Why do I have it now, and not before? Thanks for your advice. Mike.

SSH problems
by Per Qvindesland 14 Feb '09

14 Feb '09

Hi list For some odd reason after a reboot that one of my server's initiated on it's own it is now not allowing ssh logins it gives the following errors when I try to loging with ssh -v: Minor code may provide more information Unknown code krb5 195 I have googled a little and I see that other people has also had this problem and the solution seems to be to set the GSSAPIAuthentication to no and that will work, the thing that I am wondering about is if there is any ways of still being capable to login with ssh remotely I mean if there is any switch that I could use to get pass this during login.

GFS + Restarting iptables
by MARS websolutions 13 Feb '09

13 Feb '09

Dear List, I have one last little problem with setting up an cluster. My gfs Mount will hang as soon as I do an iptables restart on one of the nodes.. First, let me describe my setup: - 4 nodes, all running an updated Centos 5.2 installation - 1 Dell MD3000i ISCSI SAN - All nodes are connected by Dell?s Supplied RDAC driver Everything is running stable when the cluster is started (tested for a week or so), when I did some last changes in my firewall and did an iptables restart it all went down after a while. I reproduced the issue now several times so I am quite sure it has to do with the iptables restart. I have a custom fence script for our ipoman powerswitch, which is all tested and is working fine. When I do iptables restart the following will happen: - After approx 10 seconds the process gfs_controld will go to 100% cpu usage (at all nodes!) - I can still access my gfs Mount - The Group_tool dump gfs tells me: ---------------------- 1234541723 config_no_withdraw 0 1234541723 config_no_plock 0 1234541723 config_plock_rate_limit 100 1234541723 config_plock_ownership 0 1234541723 config_drop_resources_time 10000 1234541723 config_drop_resources_count 10 1234541723 config_drop_resources_age 10000 1234541723 protocol 1.0.0 1234541723 listen 1 1234541723 cpg 5 1234541723 groupd 6 1234541723 uevent 7 1234541723 plocks 10 1234541723 plock cpg message size: 336 bytes 1234541723 setup done 1234541737 client 6: join /setan gfs lock_dlm mars:setan rw /dev/mapper/vg_cluster-lv_cluster 1234541737 mount: /setan gfs lock_dlm mars:setan rw /dev/mapper/vg_cluster-lv_cluster 1234541737 setan cluster name matches: mars 1234541737 setan do_mount: rv 0 1234541737 groupd cb: set_id setan 20004 1234541737 groupd cb: start setan type 2 count 4 members 3 2 1 4 1234541737 setan start 3 init 1 type 2 member_count 4 1234541737 setan add member 3 1234541737 setan add member 2 1234541737 setan add member 1 1234541737 setan add member 4 1234541737 setan total members 4 master_nodeid -1 prev -1 1234541737 setan start_participant_init 1234541737 setan send_options len 1296 "rw" 1234541737 setan start_done 3 1234541737 setan receive_options from 3 len 1296 last_cb 2 1234541737 setan receive_journals from 1 to 3 len 320 count 4 cb 2 1234541737 receive nodeid 1 jid 1 opts 1 1234541737 receive nodeid 2 jid 2 opts 1 1234541737 receive nodeid 3 jid 3 opts 1 1234541737 receive nodeid 4 jid 0 opts 1 1234541737 setan received_our_jid 3 1234541737 setan retrieve_plocks 1234541737 notify_mount_client: nodir not found for lockspace setan 1234541737 notify_mount_client: ccs_disconnect 1234541737 notify_mount_client: hostdata=jid=3:id=131076:first=0 1234541737 groupd cb: finish setan 1234541737 setan finish 3 needs_recovery 0 1234541737 setan set /sys/fs/gfs/mars:setan/lock_module/block to 0 1234541737 setan set open /sys/fs/gfs/mars:setan/lock_module/block error -1 2 1234541737 kernel: add@ mars:setan 1234541737 setan ping_kernel_mount 0 1234541738 kernel: change@ mars:setan 1234541738 setan recovery_done jid 3 ignored, first 0,0 1234541738 client 6: mount_result /setan gfs 0 1234541738 setan got_mount_result: ci 6 result 0 another 0 first_mounter 0 opts 1 1234541738 setan send_mount_status kernel_mount_error 0 first_mounter 0 1234541738 client 6 fd 11 dead 1234541738 setan receive_mount_status from 3 len 288 last_cb 3 1234541738 setan _receive_mount_status from 3 kernel_mount_error 0 first_mounter 0 opts 1 1234541925 client 6: dump 1234542420 client 6: dump 1234542420 client 7 fd 11 read error -1 9 1234542424 client 6: dump 1234542424 client 7 fd 11 read error -1 9 1234542424 client 8 fd 11 read error -1 9 1234542425 client 6: dump 1234542425 client 7 fd 11 read error -1 9 1234542425 client 8 fd 11 read error -1 9 1234542425 client 9 fd 11 read error -1 9 1234542426 client 6: dump 1234542426 client 7 fd 11 read error -1 9 1234542426 client 8 fd 11 read error -1 9 1234542426 client 9 fd 11 read error -1 9 1234542426 client 10 fd 11 read error -1 9 1234542427 client 6: dump 1234542427 client 7 fd 11 read error -1 9 1234542427 client 8 fd 11 read error -1 9 1234542427 client 9 fd 11 read error -1 9 1234542427 client 10 fd 11 read error -1 9 1234542427 client 11 fd 11 read error -1 9 1234542428 client 6: dump ---------------------- - After a while the groupd process will hit 100% as well (on all nodes) - The gfs Mount will be inaccessible after a while, it hangs when trying to open it. - Group_tool still shows that all nodes are participating in the cluster and gfs service, but no problems are reported..

OT: Suggestions for connecting a postfix to an sms box

13 Feb '09

Hi there, I would like to hear some hardware recomendations to connect our smtp server (postfix) to an external SMS box. Basically I am looking for a SMS box that takes messages via smtp and sends them via the SMS part. Has anyone here implemented a solution like this? I must use an in house sms box (GSM), I cannot use a service provider (such as internet smtp to sms providers). thanks, -- ------------------------------------------------------------ Erick Perez Cel +(507) 6675-5083 ------------------------------------------------------------

Monthly Newsletter
by Didi 13 Feb '09

13 Feb '09

Hey A friend asked me how he could stay up to date with CentOS and if there was a newsletter or something. After some research I found that there was a discussion on the promo list about half a year ago but nothing happened. If you look at : http://wiki.centos.org/SpecialInterestGroup/Promo/TODO you can see, that is has to be done :) Would something like this, be appreciated by the community? What would people want to see in a newsletter? Are people interested in doing this? Personally I was thinking of : - General information (Like "whats up with 5.3") - What is happening on the mailing lists / Forum - Developer interview (Developers would you do that?) - Tips/Tricks - Event reports and up coming events - Word of the Month. Something to lighten up the newsletter. - Bug fixes - Ideas welcome I would be quite happy to contribute to this and it would give people who want to give something back a nice chance to get public exposure. Is monthly a good compromise between workload and actuality? Cheers Didi -- My NEW project : http://www.hacktags.org My www page: www.ribalba.de Email / Jabber: ribalba(a)gmail.com Skype : ribalba

Hello, I am implementing procmail with postfix on a new SMTP server, I have too many .procmailrc from my former sendmail installation and not enough time to learn maildrop and migrate right now.

Hi, I am new to clustering and loadbalancing in apache, What is best way of doing it? How do I do the clustering and what tools do I need to use? Do I have those tools, I use CentOS , Do i have any tools in CenOs which comes default in it? And how do I do apache load balancing? should I rely on apache forums or mailing list or is there any way or tool I can use in CentOS? Can any throw some vague Idea on how to do it so that I start reading documents before I do it? Thanks and regards Marky

Be aware that updating bind via yum can result in your existing bind configuration files being renamed to something.rmpsave and your name server left in a dysfunctional state. I suggest that you consider excluding bind from normal updates and only update it when you are ready and able to check for possible configuration issues. -- *** E-Mail is NOT a SECURE channel *** James B.

Problem with PXEBOOT of diskless client -- fails to mount RAMDISK
by Robert Heller 13 Feb '09

13 Feb '09

I am having a problem with setting up diskless clients under CentOS 5.2. I have everything working under CentOS 4.7. This is an adaptation of the (somewhat old) Diskless Linux with PXE HOWTO by Gerd v. Egidy, originally at the URL http://www.intra2net.com/opensource/diskless-howto/, which is now defunt (there is a mirror of it at http://blog.chinaunix.net/u/2389/showart_82438.html) What I am doing is using a RAMDISK to mount a NFS exported (read-only) root file system and copying part of it to a RAMDISK root file system, all of this after configuring the clients ethernet (via DHCP) and loading the NFS modules. The RAMDISK uses a statically built BusyBox for all of its functions, including ash. I am using the stock syslinux, dhcpd, tftp-server, and kernel RPMS. My /tftpboot directory contains: sauron.deepsoft.com% dir -l /CentOS52/tftpboot/ total 10012 -rw-r--r-- 1 root root 8388608 Feb 12 14:26 pxeboot-2.6.18-92.el5.img -rw-r--r-- 1 root root 13148 Feb 11 16:27 pxelinux.0 drwxr-xr-x 2 root root 4096 Feb 12 14:37 pxelinux.cfg/ -rw-r--r-- 1 root root 1806388 Feb 11 16:26 vmlinuz-2.6.18-92.el5 sauron.deepsoft.com% dir -lhR /CentOS52/tftpboot/ /CentOS52/tftpboot/: total 9.8M -rw-r--r-- 1 root root 8.0M Feb 12 14:26 pxeboot-2.6.18-92.el5.img -rw-r--r-- 1 root root 13K Feb 11 16:27 pxelinux.0 drwxr-xr-x 2 root root 4.0K Feb 12 14:37 pxelinux.cfg/ -rw-r--r-- 1 root root 1.8M Feb 11 16:26 vmlinuz-2.6.18-92.el5 /CentOS52/tftpboot/pxelinux.cfg: total 16K -rw-r--r-- 1 root root 101 Feb 12 14:37 default -rw-r--r-- 1 root root 134 Feb 12 14:09 default~ and /CentOS52/tftpboot/pxelinux.cfg/default contains: sauron.deepsoft.com% cat /CentOS52/tftpboot/pxelinux.cfg/default LABEL linux KERNEL vmlinuz-2.6.18-92.el5 APPEND ramdisk_size=8192 initrd=pxeboot-2.6.18-92.el5.img vmlinuz-2.6.18-92.el5 is the stock kernel, copied from /boot pxeboot-2.6.18-92.el5.img is a 8meg EXT2 filesystem image (under CentOS 4.7 the image is compressed, under CentOS 5.2, I have it uncompressed -- I seem to get 'further' that way).

ext4 in 5.3
by Jerry Geis 12 Feb '09

12 Feb '09

Hi guys - I'm really looking forward to 5.3 for the potential of ext4. I am moving/copying image files lately 8G file and it is slow. I am hoping that ext4 really speeds that up. My question is: will we be able to boot ext4 file systems? Will the boot partition still be ext3 and then have to mount the ext4 filesystem? I did not see mention of it in the release notes. Thanks, Jerry

Missing EL4 glibc update
by CentOS User 12 Feb '09

12 Feb '09

Seeing upstream has an update for glibc http://rhn.redhat.com/errata/RHBA-2009-0052.html I rebuilt the glibc-2.3.4-2.41.el4_7.1.src.rpm and it produced the following rpms :- glibc-2.3.4-2.41.el4_7.1.i386.rpm glibc-common-2.3.4-2.41.el4_7.1.i386.rpm glibc-debuginfo-2.3.4-2.41.el4_7.1.i386.rpm glibc-debuginfo-common-2.3.4-2.41.el4_7.1.i386.rpm glibc-devel-2.3.4-2.41.el4_7.1.i386.rpm glibc-headers-2.3.4-2.41.el4_7.1.i386.rpm glibc-profile-2.3.4-2.41.el4_7.1.i386.rpm glibc-utils-2.3.4-2.41.el4_7.1.i386.rpm nptl-devel-2.3.4-2.41.el4_7.1.i386.rpm nscd-2.3.4-2.41.el4_7.1.i386.rpm Is it okay to install all of them or should i skip the debuginfo rpms?

I have installed few generic user space applications of my own installed in that OS. I do not want to violate GPL or any other licenses. That's why to make sure I want to confim from you folks.

rt_cache leak in 2.6.18
by Hector Herrera 12 Feb '09

12 Feb '09

Hello, This is a CentOS 5.2 box configured as a router for a network handling about 200-300 Mbps, routing traffic to/from the internet for about 6,000 IPs. After about 2-3 days, the kernel complains about "dst cache overflow" and even thought it hasn't crashed, the network is un-responsive. All IP forwarding stops and the server cannot be reached from any network interfaces. After diagnosing the issue, it appears that there is a rt_cache leak in the kernel. At 5 minute intervals I collect the following two values: `/sbin/ip -o route ls cache | wc -l` `grep ip_dst_cache /proc/slabinfo | awk -F' ' '{ print $2; }'` The first value represents the number of cached routes in the network stack. The second value represents the number of cached route objects the kernel has allocated. After collecting the data for 8 hours, I have seen the cached routes count remain fairly constant, but the number of cached route objects increase from about 220,000 objects to 410,000 objects. The cached routes count remains between 4,000 and 8,000 routes. I posted a pretty graph at http://www.pier-pro.com/ip_dst_cache_leak.png (the blue line is the value of ip_dst_cache, the green value represents the count of cached routes). Once the ip_dst_cache value reaches the value of /proc/sys/net/ipv4/route/max_size then the network fails and the kernel complains about 'dst cache overflow' whenever a packet arrives. The only solution at that point is to perform a reboot. Flushing the routing tables by `echo 1 > /proc/sys/net/ipv4/route/flush` only clears the cached routes, however the value of ip_dst_cache does not change. According to http://linux.derkeiler.com/Mailing-Lists/Fedora/2005-07/1175.html this is a known bug that was fixed in 2.6.11, however, I'm running 2.6.18 (as updated with `yum update`) I downloaded the kernel sources, and indeed, the kernel source contains the bug fix in the above article. Therefore ... I'm at a loss as to where to go from here. Certainly rebooting the server every day is not an option, and increasing the max_size will just delay it. Suggestions? Thank you, Hector

Problems with mysql multi-master after update.
by Alessandro Ren 11 Feb '09

11 Feb '09

Hello, after I updated from mysql-5.0.22 CentOS 5.0 to mysqld-5.0.45 in CentOS 5.2, mysql looses master-slave sync after one node reboots. I've noticed that the slave doest not respect the informantion on master.info, instead, it tries to read the informantion from the master server file inc-index.index. Let me give a example, the master is alredy on incremental.000006 and the slave in synced, the master.info in the slave server is showing is is reading de incremental.000006, but in the master inc-index.index all 6 files are listed, from 1 to 6. The file 1 to 5 were already deleted in a cleaning process as thay were alread synced with the slave. After the reboot, the slave tries to find the file incremental.000001 on the master and this causes the problem. In 5.0.22 this would not happen, this does not happen as I have servers running this version and after the reboot, it starts syncing on the right incremental. Any idea? Tks.

What is the System Event Log?
by Timothy Murphy 11 Feb '09

11 Feb '09

My Dell PowerEdge T105 running Centos-5.2 has started crashing fairly often (3 times in the last 2 hours). The message on the screen tells me to look at the System Event Log. Is this just /var/log/messages ? I didn't see anything helpful there. As far as I could see, the last messages before the crash were about samba, which is running on the machine. Has anyone had such problems with Samba? I've stopped the smb service to see if this improves matters. I'm running a standard updated system. I looked at smartctl but this did not suggest that there was anything wrong with the 2 SATA disks. Incidentally, wouldn't it be a good idea for /var/log/messages* to start a new file when booting?

tinydns/djbdns opinion poll
by Jake 10 Feb '09

10 Feb '09

Good morning: We're about to start moving our public DNS to in-house managed servers. My first thought was "Linux + BIND" and we're done. Someone in another business unit's IT dept. has suggested tinydns be used. >From what I could find, it looks like this software hasn't really had any community drive behind it in a while. The latest RPMs on rpmforge are for red hat 6 and red hat 7. I very much dislike the idea of compiling my own because of all the overhead associated with making sure the system stays up-to-date and so on so this really puts me off already. Does anyone have an opinion on this software? It seems to have some strong virtues but maybe not enough to justify using it over BIND just because any Linux admin we hire could be expected to know BIND.

Scripting Oddity
by David G. Miller 10 Feb '09

10 Feb '09

I've been playing around with qemu and wanted to make the guest OS instance visible on my network. This meant getting bridging and tun/tap working. After getting things working by pasting command from the CentOS wiki article plus adding a few enhancements, I decided to capture the process in a shell script that would be suitable for a user in the sudoers file to fire off. Not sure why (which is why I'm posting this) but I couldn't get the same result from the shell script as I got from pasting commands onto the command line or using the shell history. After a lot of very tedious debugging, I finally got the script to work by adding a couple of short sleeps at selected locations. The script now looks like: cat upBridge.sh #!/bin/bash # # Script for setting up a bridge accessible by a qemu VM. # # First, make sure we're starting with a clean slate. /usr/bin/sudo /sbin/rmmod bridge /usr/bin/sudo /sbin/rmmod tun /usr/bin/sudo /sbin/service network restart # # Grab the IP address of the given interface so we can restore it later. # oldIP=`/sbin/ifconfig $1 | /bin/grep 'inet addr' | /usr/bin/awk -F \: '{print substr($2,0,index($2, " ")) ; }'` echo "$1 currently has IP address $oldIP" # # Create the bridge. # /usr/bin/sudo /usr/sbin/brctl addbr br0 /usr/bin/sudo /sbin/ifconfig $1 0.0.0.0 sleep 2 /usr/bin/sudo /usr/sbin/brctl addif br0 $1 # # Stop any dhclient still running. # /usr/bin/sudo /usr/bin/killall dhclient # # Get and IP address and routing information for the bridge # /usr/bin/sudo /sbin/dhclient br0 # # Make sure the tun module is loaded, assign it to our user and bring it up. # /usr/bin/sudo /sbin/modprobe tun echo "Did tun load?" lsmod | grep tun /usr/bin/sudo /usr/sbin/tunctl -b -u $USER sleep 2 /usr/bin/sudo /sbin/ifconfig tap0 up # # Connect the bridge and the tap. # /usr/bin/sudo /usr/sbin/brctl addif br0 tap0 /usr/bin/sudo /bin/chown $USER:users /dev/net/tun /usr/bin/sudo /sbin/iptables -I RH-Firewall-1-INPUT -i br0 -j ACCEPT # # restore the IP address of our "normal" interface. # /usr/bin/sudo /sbin/ifconfig $1 $oldIP So, my question is, why do I need to have a short sleep in these two locations in my script? Without a sleep after the "ifconfig eth0 0.0.0.0", eth0 retains its original IP address instead of having no address. The qemu guest VM still functions correctly but the host system loses connectivity. Likewise, without a sleep after the tunctl command, the device /dev/net/tun isn't present when the next command executes. With the sleeps the script executes as expected and sets up the bridge. Without the sleeps the script fails. Oh yeah. There's another script called downBridge.sh that undoes the bridge if anyone is interested. Cheers, Dave -- Politics, n.

The wiki has a long procedure for installing Sun JDK 1.6 but not JRE. What's the benefit to installing the JDK this way (repackaging it)? Thanks! jlc

process accounting - track PIDs
by nate 10 Feb '09

10 Feb '09

Hello -- I've done some searching but haven't come up with much yet, I was wondering if there was a way to track PID creation and what command was assigned to a PID? I am trying to track down a locking issue with NFS/NLM where the client PID that initiates the unlock request is not the same PID that initiates the lock request. Even with running "ps auxww" in a "while true" loop I cannot seem to capture the PID it comes/goes too fast. I can see the PID right after the one specified, but not the one I want. I tried a couple things I found for the audit system: auditctl -a entry,always -S fork -S vfork -S clone auditctl -a entry,always -S brk -F 'a0=0' auditctl -a task,always auditctl -a exit,always And none of them were able to detect the PID that was created. Another way to approach this is perhaps NLM debugging on the linux client side but I haven't had any luck tracking down useful debugging info on the client side. I saw one post mentioning a kernel patch is needed and it may make it into RHEL 5.3, though this is 4.4, so maybe it is not possible. any ideas? thanks nate

real SATA RAID
by Paolo Supino 10 Feb '09

10 Feb '09

Hi Last week I had a lengthy thread in which someone indicated the my SIL card is a FRAID (don't know if F stands for the F word or Fake, though it doesn't really matter). I want to replace the controller with a controller that Linux will see the RAID1 group as a single HD and not multiple HDs as it happens with the SIL controller. Recommendations anyone? -- TIA Paolo

CentOS promotion
by Michel Daggelinckx 09 Feb '09

09 Feb '09

I've been to FOSDEM this weekend and noticed the small number of CentOS people at the booth. The Ubuntu people work with Local Community Teams to support and promote the distro. I think it would be beneficial for CentOS to setup a similar structure. At the moment it's mostly sysadmins who introduce/sneak CentOS into businesses. Local Community Teams can setup a booth at computer fairs and other events. This way the general public (small businesses, non-profit organisations, schools, ....) are exposed to CentOS.

OFF Topic - Looking for web based file management application for law firm & clients
by Ed Morrison 09 Feb '09

09 Feb '09

Hi All: I am working with a law firm that would like to offer to it's clients the ability to access their documents through a web interface. This would require a nice gui to offer the clients with a simple process for the clients to download from. It would also need to be secure (authentication & SSL), and mandatory disclaimer acceptance before logging into their account. Anyone with experience or thoughts on this matter? Thanks, Ed

AHCI support in CentOS 5.2?
by Marko Vojinovic 08 Feb '09

08 Feb '09

My friend has an external sata hard disk, and likes the hot-plug feature. However, that works only if the appropriate sata setting in the motherboard bios is set to AHCI (IDE compatibility and RAID are two other options, but hot-plugging doesn't work with them). The machine has WinXP atm, while Linux is about to be installed in the following couple of days. Now, on wikipedia I read that AHCI is supported starting from kernel 2.6.19 and later, while current CentOS 5.2 has 2.6.18. Is it possible to make AHCI work under 2.6.18 or should I install Fedora instead? Fedora will become obsolete in a year or so, and I will not be around to reinstall it again for him, so I would prefer a long-term solution (CentOS). But I need to be sure that it can be made to do all that fancy hot-plug-auto-mount-sata-ahci stuff without too much hassle. Oh, btw, I am talking about hot-plugging using the sata cable --- usb connection of course already works, but this is a hard disk and speed increase is highly nontrivial when using sata connection compared to usb. Any suggestions? Thanks! :-) Marko

sound problem
by Paolo Supino 08 Feb '09

08 Feb '09

Hi I have CentOS 5.2 installed on a computer (the same one that I just posted a message on: Intel DG33BU motherboard) and for even though audio is reported to be found and working Linux just doesn't play anything through the speakers. The computer dual boots Linux/Windows and when in Windows sound works great, so it's strictly a Linux problem. Can anyone try and help me find out where the problem is and resolve it. -- TIA Paolo

Sound with headphones on: Streamaudio perfect but youtube and system-config-soundcard silent
by Lanny Marcus 07 Feb '09

07 Feb '09

This afternoon, I bought a pair of ear plugs (the large flat kind that hook onto my ears). Plugged them in to test and they work perfectly. I'm listening to streamaudio.com as I type this. However, when I tried to watch a youtube.com video (my wife exercise dancing) just silence. She had the same video on to test and the sound was fine on her box. Then, I tried system-config-soundcard and with the volume set at 100%, just silence. Does this have to do with lower voltages coming from youtube.com and system-config-soundcard or is there some other explanation and a cure? TIA....

Redirection in shell (was: squid HA failover?)
by Filipe Brandenburger 07 Feb '09

07 Feb '09

Hi, Regarding the last example creating the config files with several echos with redirection: On Fri, Feb 6, 2009 at 20:37, J Potter <jpotter-centos(a)codepuppy.com> wrote: > echo "node a.example.com" > /etc/ha.d/ha.cf > echo "node b.example.com" >> /etc/ha.d/ha.cf > echo "udpport 9000" >> /etc/ha.d/ha.cf > echo "bcast bond0" >> /etc/ha.d/ha.cf > echo "auto_failback off" >> /etc/ha.d/ha.cf > echo "logfile /var/log/ha-log" >> /etc/ha.d/ha.cf > echo "logfacility local0" >> /etc/ha.d/ha.cf I've seen this done too many times, and although this is the most "popular" way of doing it in shell script, it is certainly not the cleanest or the best. For one thing, it is inefficient in that it is opening the file for every command line. And the code is not easy to maintain, as if you change the filename you will have to change line by line. A better way to accomplish the same is: { echo "node a.example.com" echo "node b.example.com" echo "udpport 9000" echo "bcast bond0" echo "auto_failback off" echo "logfile /var/log/ha-log" echo "logfacility local0" } >/etc/ha.d/ha.cf And another way, using "here" documents is: cat <<EDQ >/etc/ha.d/ha.cf node a.example.com node b.example.com udpport 9000 bcast bond0 auto_failback off logfile /var/log/ha-log logfacility local0 EDQ This second one is not so clean in that it "embeds" the document inside the script, but it might be appropriate in some cases. HTH, Filipe

squid HA failover?
by Les Mikesell 07 Feb '09

07 Feb '09

I'm running a pair of squids as an internal cache for some intermediate data used by a web server farm and currently doing failover by going through an F5 bigip. However, I'd like to avoid the bigip and use heartbeat since there are only two machines. I don't need to sync any content since it is a fast-changing cache and either machine can handle everything. Is it possible to add a floating IP with heartbeat and cut over to it slowly while also still using the existing IP's on that subnet? The documentation I've seen implies that it is bad to use the real IP's. If heartbeat can't do this, would it work to use vrrp? -- Les Mikesell lesmikesell(a)gmail.com

CentOS 5.3
by kmadananteshwar.vbhat＠gmail.com 06 Feb '09

06 Feb '09

Hey folks! Does any one have an idea as to when centOS 5.3 will be out and if so then I would like to hear from you coz I am waiting for it day and night coz I heard that the kernel of centos 5.3 will have inbuilt support for intel pro/wireless 3945 wifi card ( I have been trying to install the drivers desperately with no fruit ). And by the way does any body know how I can safely upgrade from centos 5.2 to 5.3 ( when it comes out that is ) without messing up the other partitions ( I have dual booted windows vista and centos 5.2 ) ( I use windows at office and I use centos at home ) and that too the method shouldn't cause any damage to the windows installation Yours KMB Sent from BlackBerry® on Airtel

Do an "lspci -v" and find the entry for your card reader. Then check to see if it is supported by the kernel (look in /boot/config-<kernelVersion>). If it is, I don't have an answer for you. If it isn't, check to see if it's supported by the current kernel from kernel.org. If it still isn't, it's not going to work until someone implements support for that particular card reader. If it is, you have the option of building and running a custom kernel using the source from kernel.org. There are lots of how-tos on how to make this happen. That's what I did on my laptop until support for my card reader got into the RHEL/CentOS kernel. Cheers, Dave -- Politics, n.

Hey its been over a week for updated 5.3 status... http://twitter.com/centos :) Not being silly, just got a couple motherboards sitting here collecting dust as 5.2 wont install on them. Hoping 5.3 will. with all the updated NIC drivers. By the way, KB, when I got married I had the understanding that I at least got a new computer every year! Got to set things straight from the beginning! Seriously, have a great wedding. Jerry

Yum update conflicts perl-Math-BigInt
by Dan Carl 06 Feb '09

06 Feb '09

I followed the Wiki instructions for setting up *yum-priorities*. I added the rpmforge repo I installed clamd without a problem. Now when I go to update I get conflicts with perl-Math-BigInt. Is the only solution to uninstall the base version and then install the rpmforge version? According the the wiki "Packages from repositories with a lower priority will never be used to upgrade packages that were installed from a repository with a higher priority." If this true why the conflicts? please advise Thanks Dan

Re: [CentOS] Emergency rescue help needed

Personally, I find this UPS exploding paranoia rather ridiculous. One person has one UPS burst into flames and everyone is yelling the sky is falling. We have no idea what conditions the UPS had been subjected to and to then jump to the conclusion that all UPS's are bombs waiting to explode is just insane. We've been using UPS's for years and years and the worst we've had are batteries that got swollen to the point we had to use a crowbar to get them out of the UPS. We then replaced the battery and had years more use out of the UPS. We've purchased used UPS's at government auctions, replaced the batteries, and had years of service out of them. All our UPS's are APC. We have and have used a wide range of sizes, from 250VA to 3000VA, Backup's to SmartUp's. I've used/tried other brands, but haven't been as satisfied with them. APC isn't perfect, they've made some stupid mistakes, but I've been more satisfied with them than the others we've tried. Brent L. Bates (UNIX Sys. Admin.) Phone:(757) 865-1400, x204 ViGYAN, Inc.

Security update missing - kernel-2.6.18-128.el5
by Milan Keršláger 06 Feb '09

06 Feb '09

Please, do not delay this "Important" multiple security update. See https://rhn.redhat.com/errata/RHSA-2009-0225.html for more info. This update is "5.3" kernel but has been released as security update too. RHN pushed this kernel one day ahead of rest of 5.3 packages (on my servers). RH maintains API and ABI (!) compatibility so there is no problem to use this kernel AFAIK. So please, do not delay it anymore, this contains multiple security vulnerabilities fixed since 2009-01-20. Thank you for your effort (a lot). M.K. -- Milan Keršláger http://www.pslib.cz/ke/ http://www.nti.tul.cz/wiki/Milan.Kerslager

It holds the box through power variations, and can supply power for a couple of minutes - enough to allow a shutdown, since that box is never running unattended. I got it when we upgraded the company one - it was our (the company's) first, attached to the file-server, so replaced at a reasonable age. Anne

card reader issue
by Frank Cox 05 Feb '09

05 Feb '09

I have never done anything with a card reader before so I have no idea what I'm doing here. I have a laptop with a card reader in it and when I put the card in I see this in /var/log/messages: Feb 5 13:28:58 localhost pcscd: winscard.c:304:SCardConnect() Reader E-Gate 0 0 Not Found This comes up many times in the log. I suspect that this means that I'm missing some package that I should have installed, but what is it? -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com DRY CLEANER BUSINESS FOR SALE ~ http://www.canadadrycleanerforsale.com

udev by-id symlinks randomly missing for tape drives on centos5
by Pasi Kärkkäinen 05 Feb '09

05 Feb '09

Hello! I'm having problems with udev /dev/tape/by-id/ symlinks.. it seems symlinks to tape drives are sometimes (randomly) missing after reboot. Server in question has IBM TS3200 tape library connected with 2 drives in it.. so /proc/scsi/scsi shows 3 devices: 2 tape drives, and 1 medium changer (tape library). So I should have 3 symlinks in /dev/tape/by-id/ directory.. 2 symlinks to tape drives, and 1 symlink to mediumchanger/tapelibrary. Running 'udevtrigger' _sometimes_ creates the missing links, and sometimes it doesn't. Sometimes if all the symlinks are there to begin with, and you run 'udevtrigger', some of the tape drive symlinks might get removed too.. The symlink for the mediumchanger seems to be there always though.. Has anyone seen this behaviour? How to fix it? Whenever I run 'cat /proc/scsi/scsi' I can see all of the devices listed there. IBM 'itdt' tape drive / tapelibrary diagnostic tool works OK too, and always shows all the devices. I don't have any errors in the dmesg/syslog, and the devices work OK if I use /dev/nst* (tape drives) or /dev/sg* (mediumchanger/tapelibrary) devicenames to access them. I'd like to be able to use /dev/tape/by-id/<foo> symlinks to make sure correct devices are accesssed. The server in question is running CentOS 5.2 x86_64 (with latest updates installed). Any thoughts? -- Pasi

Missing latest kmod-xfs and kmod-drbd82?
by Alan Sparks 04 Feb '09

04 Feb '09

Since December there have been several kernel updates to the centosplus repository for centos4... but no updates to kmod-xfs or kmod-drbd82. Latest kernel is 2.6.9-78.0.13.plus.c4, but latest kmod-xfs is 2.6.9_78.0.5.plus.c4. Latest drbd82 kmod is also for 78.0.5. I know there was a mention on the list that these modules are not kernel dependent anymore... but yum and rpm seem to indicate otherwise, and trying to install kmod-xfs-smp or update kmod-drbd82-smp on my servers is not possible. $ rpm -qRp kmod-xfs-smp-0.4-1.el4.2.6.9_78.0.5.plus.c4.x86_64.rpm /bin/sh /bin/sh /sbin/depmod /sbin/depmod kernel-smp-x86_64 = 2.6.9-78.0.5.plus.c4 rpmlib(CompressedFileNames) <= 3.0.4-1 rpmlib(PayloadFilesHavePrefix) <= 4.0-1 rpmlib(VersionedDependencies) <= 3.0.3-1 Above, the last available version of the module shows a dependency on the 78.0.5 kernel. These modules will of course also install in the wrong /lib/modules/ location. I've over the last two months opened tickets on bugs.centos.org on the issue (tickets 3360, 3316, 3291). However, these tickets are still new and have had no comments. Anyone have any advice on dealing with the missing RPMs or the dependency issue? Thanks in advance. -Alan

There's a reason I don't like running anything beyond my ALIX-router 24x7 at home (while I'm away). And it's not the power-bill. IMO, UPSs don't really belong in the living-room. Doesn't really matter if they are old or new. Imagine returning home from work, only to find only the smoldering remainders of what was your house in the morning... Rainer

kickstart won't kick-off via network

Hello list, I try to do an automated network installation of centos 5.2, following the redat documentation at http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/sysadmin-guide/… However, when installing I get promptet for various things, like which network interface I would like to use for installation, or the location of the install medium. But thats not what I wanted, I want to start the boot process, and then leave the box untill it is installed. What I did: First a manual install form DVD. I then used the kickstart file /root/anaconda-ks.cfg for a network installation. I changed the install line from cdrom to url: install url --url http://9.0.0.1/all/repository/CentOS5.2 This url contains the whole DVD (and can be viewed in a webbrowser). Then I generated the following entry in my pxe control file (default): LABEL centos5.2_cluto_cnode MENU LABEL CentOS 5.2 cluto ^node kernel distro/centos5.2/vmlinuz append initrd=distro/centos5.2/initrd.img ramdisk_size=7494 ks=http://9.0.0.1/all/profiles/cluto_centos5.2/cnode/ks.cfg This is part of a boot menue, therefor the MENU entry. The url of the kickstart file is also valid, I can wget it. Now since I get asked all these questions at boot time, I suspect that the kickstart file is not there to answer these questions. I would be greatful for any suggestions on how to further debug or solve this.

> Especially since FDD aren't that common anymore... I'll see if I can't adapt > my SOP:s to boot and install from network. The set up is actually not too complicated. I really recommend it, you just plug in the computer and let it install. There are various variants, you can either define what will be installed by naming the pxe controll file according to the mac address, or you can make a default boot menue. Boot menues are described here: http://syslinux.zytor.com/wiki/index.php/PXELINUX#Custom_Menu_Example_with_… good luck, Isaac _____________________________________________________________________ Vorstand: Ertu Uysal, Axel Queck Vorsitzender des Aufsichtsrats: Bernhard Bruscha Sitz der Gesellschaft: Tuebingen Amtsgericht Stuttgart HRB 381299 Diese E-Mail enthaelt vertrauliche und/oder rechtlich geschuetzte Informationen.

Another issue can be that you aren't backing up the air conditioner power, so when the grid goes down your still-running equipment overheats, damaging the electronics. This is particularly likely if your servers are racked densely in a small space. -- Les Mikesell lesmikesell(a)gmail.com

Does your > ks.cfg contain some lines for the networking? Yes: # Kickstart file automatically generated by anaconda. install url --url http://9.0.0.1/all/repository/CentOS5.2 [...] network --device eth0 --bootproto dhcp --hostname node1.cluster network --device eth1 --bootproto dhcp --hostname node1.cluster [...] > You didn't modify the ks.cfg you > mention above, did you? Yes, I modified the part after install. It used to be "cdrom". > You can open the ks.cfg you already have and then tweak with the wizard. I opened the ks.cfg with system-config-kickstart. I configured it to install from network. It produced the following: #platform=x86, AMD64, or Intel EM64T # System authorization information auth --useshadow --enablemd5 # System bootloader configuration bootloader --append="rhgb quiet" --location=mbr --driveorder=sda # Partition clearing information clearpart --linux --drives=sda # Use graphical install graphical # Firewall configuration firewall --disabled # Run the Setup Agent on first boot firstboot --disable # System keyboard keyboard us # System language lang en_US # Installation logging level logging --level=info # Use network installation url --url=http://9.0.0.1/all/repository/CentOS5.2 # Network information network --bootproto=dhcp --device=eth0 --onboot=on network --bootproto=dhcp --device=eth1 --onboot=on #Root password rootpw --iscrypted $xxx # SELinux configuration selinux --disabled # System timezone timezone --isUtc America/New_York # Install OS instead of upgrade install # X Window System configuration information xconfig --defaultdesktop=GNOME --depth=8 --resolution=640x480 --startxonboot # Disk partitioning information part / --bytes-per-inode=4096 --fstype="ext3" --size=25000 part swap --bytes-per-inode=4096 --size=8000 part /home --bytes-per-inode=4096 --fstype="ext3" --grow --size=100 %packages @base-x Now in conjunction with the kernel parameter ksdevice=eth1 (thank you Kai!) this works like a charm. I seems that I misunderstood the use of "install" and "url". - Comming form SLES and autoyast I thought I should avoid the gui, but kickstart seems to do better here - Thank you!
