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. Regards Per Qvindesland

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.

by Anto Marky 13 Feb '09

13 Feb '09

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?

Dear Friends, I have few questions. 1. I have a device on which I have installed CentOS 5.2 as an operating system. Now I want to sell this device.

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.

Seems like Squirrelmail is not doing so good here over the last few months. John Hinton

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
