Broadcom NetXtremeII and CentOS 6
by stwe22＠comcast.net 11 Oct '11

11 Oct '11

Has anyone managed to get CentOS 6 x86_64 running on a server with a Broadcom NetXtremeII BCM5709 network adaptor? If so have you seen any issues with the network freezing? On booting everything works fine then the network will just stop - can't ping anything. If we manually restart the network service it will run again for a few seconds/minutes before hanging again. We have even installed the latest bnx2 drivers (netxtreme2-6.2.23) as supplied by the server manufacturer - problem remains. Any ideas/thoughts would be greatly appreciated.

trace?
by hadi motamedi 11 Oct '11

11 Oct '11

Dear All I have installed an announcement application on my centos 6.0 server that calls for putting specific voice announcement files under /usr/local/srf/bin/prompt to be played in response to certain conditions occurred . There are a huge number of files in the announcement directory and it seems that just one of these voice files is corrupt . Can you please let me know how can I trace in real time to see which application is going to use this folder and which of these files will be accessed at the moment ? My goal is to find that corrupted voice file in real time . Thank you

Is there a problem with C6 CR and glibc?
by Patrick Bervoets 11 Oct '11

C6 with CR x86_64 Third time when trying to install a packet I get: yum install samba [...] --> Finished Dependency Resolution Error: Package: glibc-2.12-1.7.el6_0.5.i686 (updates) Requires: glibc-common = 2.12-1.7.el6_0.5 Installed: glibc-common-2.12-1.25.el6_1.3.x86_64 (@cr) glibc-common = 2.12-1.25.el6_1.3 Available: glibc-common-2.12-1.7.el6.x86_64 (base) glibc-common = 2.12-1.7.el6 Available: glibc-common-2.12-1.7.el6_0.3.x86_64 (updates) glibc-common = 2.12-1.7.el6_0.3 Available: glibc-common-2.12-1.7.el6_0.4.x86_64 (updates) glibc-common = 2.12-1.7.el6_0.4 Available: glibc-common-2.12-1.7.el6_0.5.x86_64 (updates) glibc-common = 2.12-1.7.el6_0.5 Had the same problem yesterday with a Canondriver-rpm and earlier with either Hugin or Scribus. Searched on Google and found many old pages (afaik nothing C6). I don't think there is a glibc-common i686 package (neither do I know if that would be a good idea). Should I downgrade glibc-common to 2.12-1.7? Or install a second glibc-common? Or just wait? BTW I tried to install Samba with only Base, Updates and CR repo enabled. Thanks Patrick

CentOS Summit?
by Kay Williams 10 Oct '11

10 Oct '11

Hello, I am writing to gauge interest in holding a gathering for CentOS users, admins and developers? A conference is a fun and efficient way for like-minded individual to meet, learn about each other, share stories, exchange ideas, provide support and friendship, and come up with even better ideas for the future. If there is sufficient interest, I would be willing to help organize. Perhaps an event could be held around the same time as other relevant conferences such as LinuxCon or OSCon. Let me know your thoughts. Kay Williams kay(a)thewilliams.net P.S. By way of background, I have been working with CentOS since the early days, but prior to that I worked at Microsoft for many years where it was often my role to organize and present at technology summits. I am sure we can come up with a format that is fun, relevant and interesting.

Choosing a CentOS version
by Bade Iriabho 10 Oct '11

10 Oct '11

This may be a noob question but there is something I have been trying to understand, there are currently three main versions of CentOS 4, 5, and 6. My main question is simply how do I know what version I should deploy? I have searched online and either I did not do a good job of searching or the information I get is inadequate. To better understand why I ask this question, here are some of the build up questions. - Is there an online resource that lists (compare/contrast) the different versions (i.e. 4, 5, and 6) and why you should pick a particular one? - Is a particular version the best for a web server, how do I know this? - Should or does it matter what version I deploy? - Can assume that once a version is decided upon, one should stick to the latest release. i.e. for version 5, go with 5.7 right now? If you can point me to an online resource, that would be awesome as well. B.I.

I finally deleted ifcfg-bro and used the existing ifcfg-eth0 and -eth1 scripts to at least get a network connection working. When I start the network service I only saw l0 and eth0 start as eth1 is disabled. However, when I did an ifconfig I saw that br0 is configured as well, but not by me. Looking for br0 in the file system led me to the directories listed above. I do not recall seeing these before and the only difference between this CentOS box and the previous virtual host I installed is that this time I selected the virtual host install option instead of minimal install. Evidently this was a misstep on my part. One that I doubt I shall repeat. My questions are: What are these duplicate, and identical, files doing in multiple places on my system; and why are they evidently interfering with the normal processing of /etc/sysconfig/network-scripts through the service utility? -- *** E-Mail is NOT a SECURE channel *** James B.

CentOS 6.0 CR mdadm-3.2.2 breaks Intel BIOS RAID
by Trey Dockendorf 09 Oct '11

09 Oct '11

I just upgraded my home KVM server to CentOS 6.0 CR to make use of the latest libvirt and now my RAID array with my VM storage is missing. It seems that the upgrade to mdadm-3.2.2 is the culprit. This is the output from mdadm when scanning that array, # mdadm --detail --scan ARRAY /dev/md0 metadata=imsm UUID=734f79cf:22200a5a:73be2b52:3388006b ARRAY /dev/md126 metadata=imsm UUID=3d135942:f0fad0b0:33255f78:29c3f50a mdadm(IMSM): Unsupported attributes : 40000000 mdadm: IMSM metadata loading not allowed due to attributes incompatibility. mdadm(IMSM): Unsupported attributes : 40000000 mdadm: IMSM metadata loading not allowed due to attributes incompatibility. ARRAY /dev/md127 container=/dev/md0 member=0 UUID=734f79cf:22200a5a:73be2b52:3388006b The error about IMSM shows up on google as something that happened to Fedora users during a FC14->FC15 upgrade. The server itself isn't old, it's a Supermicro 2U with Dual Xeon 5400 family of CPU. There are two RAIDs on this one controller...a RAID1 which still functions and a RAID5 which is the one that is unable to be seen. I don't know what IMSM is for, but the only thing strange about that array is it is 2.7TB so the BIOS configured it as two separate arrays, one as 2TB and one as 700GB, but it was showing up to CentOS as a single volume. I downgraded to 3.2.1 , ran mdadm again and bam...it works, # mdadm --detail --scan ARRAY /dev/md0 metadata=imsm UUID=734f79cf:22200a5a:73be2b52:3388006b ARRAY /dev/md126 metadata=imsm UUID=3d135942:f0fad0b0:33255f78:29c3f50a ARRAY /dev/md127 container=/dev/md0 member=0 UUID=691f975d:6beecfd8:67b39886:b7ee7f6e Hopefully this can be fixed before this version makes it to 6.1, though it's likely a problem for upstream RHEL as well. - Trey

CentOS CVE "database"?
by Nate Duehr 08 Oct '11

08 Oct '11

Was working on a project tonight to document CVE fixes applied to servers, and noted that RedHat has completely jacked up their website. In the past, I've usually just used their website for links to their CVE list, as well as links to their Errata to look up specifics for CentOS machines. It sure looks like these links are either permanently gone from the public pages to be hidden internally only available to Subscribers, or... RedHat's Marketing folks have completely destroyed what was once a valuable information-filled website. Either way... the question now becomes... Is there something similar to RedHat's CVE listings by year and number hosted by anyone in the CentOS community or by CentOS itself for CentOS? I haven't had much luck with my GoogleFu tonight. Thanks, Nate

CentOS-6.0 Continuous Release ( CR ) repository
by Timothy Murphy 08 Oct '11

08 Oct '11

I don't really understand the function of this repository, or rather why the RPMs in it are not in the standard repository? I read the outline at <http://wiki.centos.org/AdditionalResources/Repositories/CR>, and added the repository on two CentOS machines. On yum-updating some 450MB of updates were installed. Both machines appear to be running perfectly well. -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

Unable to run yum update

08 Oct '11

Folks The system involved is a 32-bit system, installed via the net about a week ago. The command yum update encountered the following diagonstic Error: Package: yaf-1.3.2-1.el6.rf.x86_64 (@rpmforge) Requires: libfixbuf-0.9.0.so.8()(64bit) Removing: libfixbuf-0.9.0-1.el6.rf.x86_64 (@rpmforge) libfixbuf-0.9.0.so.8()(64bit) Updated By: libfixbuf-1.0.1-1.el6.rf.x86_64 (rpmforge) Not found You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest The repositories I use are: base epel extras rpmforge updates virtualbox I wonder if using priorities would help? Rpmforge is "supposed" to be non-conflicting, but then.... Please let me know what I should do. David

Installing Ruby gems on RPM-based systems
by Kenneth Porter 08 Oct '11

08 Oct '11

When I first got involved with Red Hat (back with 5.2 in the early 90's) I learned the hard way not to use language-specific packaging systems like CPAN for Perl because they'd conflict with RPM's database and make it much harder to manage what was installed on my system. If I now need a package for which no RPM is available, I'll use a utility like cpanspec to repackage it into an RPM and install that. Now I'm starting to work with Ruby and apparently it has its own packages called "gems". How do people deal with making Ruby and RPM get along? I'm trying to build Diaspora, an open source alternative to Facebook, and it wants me to install a ton of gems. I'm working on a "disposable" machine that I can re-image at will, so I let it use Ruby's "bundle install" command to dump all the gems from the Ruby repositories into their system location. But in a "real" installation I'd want to do this with RPM, repackaging gems as needed. What's available to do this properly? <https://github.com/diaspora/diaspora/wiki/Installing-and-Running-Diaspora>

Virtual RPM howto?
by Kenneth Porter 08 Oct '11

08 Oct '11

Can someone point me to a howto or an example of a virtual package? I'm building Diaspora (the open source competitor to Facebook) and I figured it would be handy to gather all the prereqs into a virtual package. I'm working from these instructions, which seemed to go fine on CentOS 6: <https://github.com/diaspora/diaspora/wiki/Installing-on-Fedora>

[C6] Some typical apps missing?
by Marko Vojinovic 08 Oct '11

08 Oct '11

Hi everyone! :-) I just installed CentOS 6 on one of my desktop machines, and yum now tells me that some of my favorite apps are not present in any of the repositories I configured. To name a few: ktorrent, kile, krusader, pavucontrol, mplayerplug-in (or is it now gecko-mediaplayer), xine, xmms, and so on... All these apps were readily available for C5, and I used them happily. I am mostly surprised with the absence of *any* torrent client, bar the rtorrent (which doesn't have a man page and I have no idea how to use it). Also kile, krusader and pavucontrol are quite basic and common apps... The configured repositories are: base, updates, extras, rpmforge, elrepo, as reported by yum. What am I missing? I would also be grateful if anyone has a suggestion for a reasonable (and available) substitute for any of these apps. I usually prefer KDE4 apps, but will use anything that works. I found some (rtorrent, mozilla-vlc, gnome-volume-control), but I am not exactly thrilled with their quality, so I'm hoping someone has a better suggestion. Google didn't want to be my friend this time, all hits were related to C5... ;-) TIA, :-) Marko

BIND and a second server resolving itself
by Bob Hoffman 07 Oct '11

07 Oct '11

I am installing my second server in the datacenter but having problems getting to the net with it. I am going to use it as a KVMvirt host and do not want to run bind on its base OS. My thought was to just refer to it in the bind zones as an additional record (main.example.com is the working server now, main2.example.com is the new one). I cannot get the new one to reach out to the net, is there something I have to do on the new server to make it resolve correctly (I have listed my nameservers and hosts file and all that)? I think I have to allow my original server, the one hosting the nameservers, to allow the new server access to query, is that right? or do I just need to add the IN A record with the ip, main2.example.com. IN A xxx.x..x...x..? this is the first time I ever went with two servers and a bit confused as to proper resolution on the second server without having bind on it... any help appreciated. happy friday all

CentOS 6.x cr repo
by Janne TH. Nyman 07 Oct '11

07 Oct '11

Team CentOS, Just writing to thank you a lot for the CentOS 6.1 packages made available on the 26th of September. I haven't gone through what updates exactly you guys released in the cr repository but I am well impressed with the improvements. Great timing as my RHEL self-support contract was due for renewal and I am so pleased with the refreshed packages, it now works on my ThinkPad X220, that I won't renew my RHEL subscription. Awesome work guys and thanks a million. :) CentOS Rocks. Ps. I found the CR repo information here: http://lists.centos.org/pipermail/centos-announce/2011-September/018078.html Janne Nyman AKA JNixus E: jnyman(a)jbtec.org

Migrating CentOS 5 -> 6: where to put /etc/inittab respawn scripts?
by Alexander Farber 07 Oct '11

07 Oct '11

Hello, sorry, for 1 more question on CentOS 5 -> CentOS 6 migration. On my old CentOS 5.7 machine I have the following line: pref:3:respawn:/bin/su -c '/usr/local/pref/pref.pl >/tmp/pref-`date +%a`.txt 2>&1' afarber and this has served me well, I don't want to install anything else like daemontools etc. - to keep my web-server easily reinstallable (or movable to another hoster). But now I have migrated to CentOS 6.0, added that line and the "init q", but nothing happens - as indeed promised by the comments in the new /etc/inittab. Where should I move my line, which docs to read? The pref.pl is a poll()ing TCP-sockets daemon for a game Thank you Alex

I hadn't mention that I messed up the bridge setup. I didn't think that could lock up the host machine, but it did. Once I had the bridge fixed, the crashing stopped and network has been working on the guest. So it was my bad there. I thought that an incorrect network config would only affect networking, but it was causing a kernel panic.

CentOS 6 and Pyzor
by John Hinton 06 Oct '11

06 Oct '11

Had anybody been successful in getting Pyzor to run on CentOS 6 64bit? I have it running fine on CentOS 6 32 bit, and I 'think' I did identical installs. But, from the command line I keep getting Oct 6 13:36:00.659 [16065] dbg: pyzor: network tests on, attempting Pyzor Oct 6 13:36:06.205 [16065] dbg: pyzor: pyzor is available: /usr/bin/pyzor Oct 6 13:36:06.206 [16065] dbg: pyzor: opening pipe: /usr/bin/pyzor check < /tmp/.spamassassin160655GZkVEtmp Oct 6 13:36:06.281 [16065] dbg: pyzor: [16168] finished: exit 1 Oct 6 13:36:06.282 [16065] dbg: pyzor: check failed: no response And, yes the firewall port is open and I can ping pyzor. Been Googling this for hours now.... lots of returns without any helpful info. And 'odd' that it is running fine on 32 bit. And of course, the 32 bit install is for internal use while the 64 bit system needs to go live to the public really fast! -- John Hinton 877-777-1407 ext 502 http://www.ew3d.com Comprehensive Online Solutions

Permission question
by Victor Padro 06 Oct '11

06 Oct '11

Hello, We own a CentOS Server which hosts a few domains using Cpanel, however each host or domain has its own user and its own folder under /home, we want a separate user(newuser1) to have read and write privileges in all home's subdirectories so we can do some tasks remotely using WinSCP, that user is already in the sudoers group and the root login is disabled in SSH for security, but I haven't been able to assign the correct privileges and rights to newuser1 using chmod -R owneruser:newuser1 /home/owneruserdir, everytime we login with newuser1 using WinSCP to /home and try to change directory to /home/owneruserdir we receive a permission denied message, so I don't know where else to look. Any pointers will be apreciated. Thanks. -- "Everything that irritates us about others can lead us to an understanding of ourselves"

Confgure SAN with Linux
by MARMEY Cyril 06 Oct '11

06 Oct '11

Hi, i'm new to this subject. I try to present a san attachment on my Linux server (OEL 5.5). I'm running a HP server with qlogic 2462 and my SAN Storage is a HP EVA. Zoning is good. I installed HP SanSurfer and i see the vdisk with this utility. But, impossible to see the volume from the os. Fdisk returns me to the local disks, and multipath -l command does not return any info. I installed qlogic drivers, edit multipah.conf, install devicee mapper .... Have you any idea or how to ? I hope I was clear, I started with Linux and I can not put all the necessary information.

guest vms crash host systems
by Negative 06 Oct '11

06 Oct '11

I built guest vm's one for Windows 7 and one for Windows XP using the virtual machine manager on a just updated to centos 5.7, and they are both crashing the host machine. They run only for a few minutes, but suddenly freeze, crashing the host. There is no networking. No X. No way to drop out of X. The only way out is a hard reboot. I don't see anything in the logs -- messages or libvirt logs -- immediately before the crash. I haven't found anything like this on the web or on this list. The workstation has two xeon E5410s. I noticed that both the kvm-amd and kvm-intel modules are loaded, but don't know if that would cause a problem. I had an ati firepro graphics card in the machine, but suspected that might be the source of some conflict, and I put in an Nvidia card. The vm's were built with all the defaults. The configuration is just about identical to vms I have running on a smaller machine with a dual core Athalon. Thanks for any suggestions.

CentOS 6 USB changes
by m.roth＠5-cent.us 05 Oct '11

05 Oct '11

Ok, I just managed, after much effort, to rebuild my USB key to install CentOS 6. There are a number of changes. Partition the USB key, but make partition 1, Win 95 (FAT32) (I think that's partition type "b"), bigger. I made it 500M. The rest should be ext3 (or whatever). Format the partitions. Make sure to toggle the bootable flag on partition 1. syslinux /dev/<DOS partition> When you're done, the DOS partition should look like this: ls -laF /mnt /boot/ /ldlinux.sys /syslinux/ Under /boot is /grub, and it's contents. Make sure you create a grub.conf to put in there. If syslinux didn't put it there, mount your .iso, and copy /mnt/iso/isolinux into there, then rename /syslinux/isolinus.cfg to /syslinux/syslinux.cfg. I put a grub.conf here, too: cat /mnt/disk/syslinux/grub.conf #debug --graphics default=0 splashimage=@SPLASHPATH@ timeout 5 hiddenmenu title @PRODUCT@ @VERSION@ kernel @KERNELPATH@ initrd @INITRDPATH@ title Install system with basic video driver kernel @KERNELPATH@ xdriver=vesa nomodeset askmethod initrd @INITRDPATH@ title rescue kernel @KERNELPATH@ rescue askmethod initrd @INITRDPATH@ On the second partition, copy your .iso images. Then copy /mnt/iso/images there. You should be good to go. NOTE: during the install, if you make any partitions encrypted, it will hang when it's done formatting, so reboot, and tell it to install again, and then not to format. It will start, then ask for the password, then actually go through the install. mark

Howto use Gmail with sendmail on CentOS 6
by Alexander Farber 05 Oct '11

05 Oct '11

Hello, I hope nobody minds, if I post a short summary here for archives - How to forward mails via Gmail account from CentOS 6 (I use sendmail, because haven't figured out how to setup Postfix yet): # yum erase postfix # yum install sendmail sendmail-cf cyrus-sasl-plain cyrus-sasl-md5 # mkdir /etc/mail/auth # chmod 700 /etc/mail/auth Create the file /etc/mail/auth/client-info: AuthInfo:smtp.gmail.com "U:smmsp" "I:your_gmail_address" "P:your_password" "M:PLAIN" AuthInfo:smtp.gmail.com:587 "U:smmsp" "I:your_gmail_address" "P:your_password" "M:PLAIN" # cd /etc/mail/auth # makemap -r hash client-info.db < client-info # chmod 600 client-info client-info.db Then edit /etc/mail/sendmail.mc (most lines are there already and just need to be uncommented and edited a bit): define(`SMART_HOST', `smtp.gmail.com')dnl define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl FEATURE(`authinfo',`hash /etc/mail/auth/client-info')dnl define(`confCACERT_PATH', `/etc/pki/tls/certs')dnl define(`confCACERT', `/etc/pki/tls/certs/ca-bundle.crt')dnl define(`confSERVER_CERT', `/etc/pki/tls/certs/sendmail.pem')dnl define(`confSERVER_KEY', `/etc/pki/tls/certs/sendmail.pem')dnl define(`confCLIENT_CERT', `/etc/pki/tls/certs/sendmail.pem')dnl define(`confCLIENT_KEY', `/etc/pki/tls/certs/sendmail.pem')dnl Then create certificates (I've used "DE", "NRW", "Bochum", "my hostname", "my gmail address" there as input): # cd /etc/pki/tls/certs # make sendmail.pem Append the following line to /etc/aliases: root: your_gmail_address and run "newaliases". If you need, also append "apache" to /etc/mail/trusted-users. Finally: # cd /etc/mail # make (this will generate new sendmail.cf) # service sendmail restart and check the /var/log/maillog for error messages while sending test mail messages from command line.

postmap: fatal: open database /etc/postfix/sasl_passwd.db: Permission denied

I'm trying to configure mail forwarding through Gmail on CentOS 6 with postfix, following the blog http://carlton.oriley.net/blog/?p=31 and I think the blog has missed the step: # postmap /etc/postfix/sasl_passwd - as I've seen in the /var/log/maillog: postfix/smtp[1926]: fatal: open database /etc/postfix/sasl_passwd.db: No such file or directory postfix/master[1831]: warning: process /usr/libexec/postfix/smtp pid 1926 exit status 1 postfix/master[1831]: warning: /usr/libexec/postfix/smtp: bad command startup -- throttling But when I try to run postmap, I get postmap: fatal: open database /etc/postfix/sasl_passwd.db: Permission denied even though the postfix service is stopped, the SELinux is permissive and the file is writable: [root@preferans postfix]# ll -rw-r--r--. 1 root root 20K Jun 25 14:50 access -rw-r--r--. 1 root root 12K Jun 25 14:50 canonical -rw-r--r--. 1 root root 9.7K Jun 25 14:50 generic -rw-r--r--. 1 root root 18K Jun 25 14:50 header_checks -rw-r--r--. 1 root root 27K Oct 4 20:24 main.cf -rw-r--r--. 1 root root 27K Oct 4 20:23 main.cf.OLD -rw-r--r--. 1 root root 5.0K Jun 25 14:50 master.cf -rw-r--r--. 1 root root 6.7K Jun 25 14:50 relocated -rw-r--r--. 1 postfix root 113 Oct 4 20:25 sasl_passwd -rw-r--r--. 1 root root 13K Jun 25 14:50 transport -rw-r--r--. 1 root root 13K Jun 25 14:50 virtual Has anybody fought this problem already?

Problems with Intel Ethernet and module e1000e
by Volker Poplawski 04 Oct '11

04 Oct '11

Hi all, I'm facing a serious problem with the e100e kernel module for Intel 82574L gigabit nics on Centos 6. The device eth0 suddenly stops working i.e. no more networking. When I do ifconfig from console I get eth0 Link encap:Ethernet HWaddr 00:xx:xx:xx:xx:EA inet6 addr: fe80::225:90ff:fe50:8fea/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:37984 errors:54245436935850 dropped:9040906155975 overruns:0 frame:36163624623900 TX packets:20884 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4431149 (4.2 MiB) TX bytes:4628666 (4.4 MiB) Memory:fb900000-fb920000 Reported byte count and RX TX packet count is reasonable. Howerver the incredible large number of errors is not. Also they don't pile up but simply appear when the device stopped working. In /var/log/messages I get: Sep 23 12:21:09 wader2 kernel: ------------[ cut here ]------------ Sep 23 12:21:09 wader2 kernel: WARNING: at net/sched/sch_generic.c:261 dev_watchdog+0x26d/0x280() (Not tainted) Sep 23 12:21:09 wader2 kernel: Hardware name: X9SCL/X9SCM Sep 23 12:21:09 wader2 kernel: NETDEV WATCHDOG: eth0 (e1000e): transmit queue 0 timed out Sep 23 12:21:09 wader2 kernel: Modules linked in: tun ebtable_nat ebtables xt_CHECKSUM iptable_mangle ipt_MASQUERADE iptable_nat nf_nat sunrpc bridge stp llc xt_physdev ipt_REJECT nf_conntrack_ipv4 nf_defrag_ipv4 iptable_filter ip_tables ip6t_REJECT nf_conntrack_ipv6 xt_state nf_conntrack ip6table_filter ip6_tables ipv6 kvm_intel kvm serio_raw i2c_i801 i2c_core iTCO_wdt iTCO_vendor_support sg e1000e ext4 mbcache jbd2 sd_mod crc_t10dif ahci megaraid_sas dm_mod [last unloaded: scsi_wait_scan] Sep 23 12:21:09 wader2 kernel: Pid: 0, comm: swapper Not tainted 2.6.32-71.29.1.el6.x86_64 #1 Sep 23 12:21:09 wader2 kernel: Call Trace: Sep 23 12:21:09 wader2 kernel: <IRQ> [<ffffffff8106b947>] warn_slowpath_common+0x87/0xc0 Sep 23 12:21:09 wader2 kernel: [<ffffffff8106ba36>] warn_slowpath_fmt+0x46/0x50 Sep 23 12:21:09 wader2 kernel: [<ffffffff8142a07d>] dev_watchdog+0x26d/0x280 Sep 23 12:21:09 wader2 kernel: [<ffffffff8107d3c5>] ? internal_add_timer+0xb5/0x110 Sep 23 12:21:09 wader2 kernel: [<ffffffff81429e10>] ? dev_watchdog+0x0/0x280 Sep 23 12:21:09 wader2 kernel: [<ffffffff8107dfc7>] run_timer_softirq+0x197/0x340 Sep 23 12:21:09 wader2 kernel: [<ffffffff810a0e90>] ? tick_sched_timer+0x0/0xc0 Sep 23 12:21:09 wader2 kernel: [<ffffffff8102f52d>] ? lapic_next_event+0x1d/0x30 Sep 23 12:21:09 wader2 kernel: [<ffffffff81073d67>] __do_softirq+0xb7/0x1e0 Sep 23 12:21:09 wader2 kernel: [<ffffffff81095c50>] ? hrtimer_interrupt+0x140/0x250 Sep 23 12:21:09 wader2 kernel: [<ffffffff810142cc>] call_softirq+0x1c/0x30 Sep 23 12:21:09 wader2 kernel: [<ffffffff81015f35>] do_softirq+0x65/0xa0 Sep 23 12:21:09 wader2 kernel: [<ffffffff81073b65>] irq_exit+0x85/0x90 Sep 23 12:21:09 wader2 kernel: [<ffffffff814d0a31>] smp_apic_timer_interrupt+0x71/0x9c Sep 23 12:21:09 wader2 kernel: [<ffffffff81013c93>] apic_timer_interrupt+0x13/0x20 Sep 23 12:21:09 wader2 kernel: <EOI> [<ffffffff812dac0f>] ? acpi_idle_enter_bm+0x28f/0x2c3 Sep 23 12:21:09 wader2 kernel: [<ffffffff812dac08>] ? acpi_idle_enter_bm+0x288/0x2c3 Sep 23 12:21:09 wader2 kernel: [<ffffffff813df687>] cpuidle_idle_call+0xa7/0x140 Sep 23 12:21:09 wader2 kernel: [<ffffffff81011e96>] cpu_idle+0xb6/0x110 Sep 23 12:21:09 wader2 kernel: [<ffffffff814b1a0a>] rest_init+0x7a/0x80 Sep 23 12:21:09 wader2 kernel: [<ffffffff818c3f19>] start_kernel+0x413/0x41f Sep 23 12:21:09 wader2 kernel: [<ffffffff818c333a>] x86_64_start_reservations+0x125/0x129 Sep 23 12:21:09 wader2 kernel: [<ffffffff818c3438>] x86_64_start_kernel+0xfa/0x109 Sep 23 12:21:09 wader2 kernel: ---[ end trace 69b6c5e494cffe4d ]--- Sep 23 12:21:10 wader2 kernel: 0000:04:00.0: eth0: Error reading PHY register Sep 23 12:21:10 wader2 kernel: e1000e: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX The last line falsely reports the link to be 1000Mbit but it is actually 100Mbit. Same does ethtool. Bringing down the interface with ifconfig eth0 down and then ifconfig eth0 up does not help. A reboot gets the interface back to normal. The problem returns after some minutes, hours or a day. Any ideas? Regards .......Volker

Expunge Old Email
by John Hinton 04 Oct '11

04 Oct '11

For those of you running mailservers on CentOS 6, what are the suggestions for programs to expunge old email? For instance, deleting email from a Spam folder that is 2 weeks old or older. I see that Dovecot does have a solution, but was wondering about what others have landed on. My systems are basically Postfix, Dovecot using Maildir. Thanks, John Hinton

CentOS 6: Increase shared memory limits permanently
by Alexander Farber 04 Oct '11

04 Oct '11

Hello again, on CentOS 6 / 64 bit what is please the best way to permanently increase the shared memory? I'd like to give shared_buffers = 4096MB to PostgreSQL 8.4 on my machine with 16 GB RAM, but I currently only have: # sysctl -A|grep shm kernel.shmmax = 33554432 kernel.shmall = 2097152 kernel.shmmni = 4096 and this produces the error in /var/lib/pgsql/pgstartup.log: FATAL: could not create shared memory segment: Invalid argument DETAIL: Failed system call was shmget(key=5432001, size=4399202304, 03600). HINT: This error usually means that PostgreSQL's request for a shared memory segment exceeded your kernel's SHMMAX parameter. You can either reduce the request size or reconfigure the kernel with larger SHMMAX. To reduce the request size (currently 4399202304 bytes), reduce PostgreSQL's shared_buffers parameter (currently 524288) and/or its max_connections parameter (currently 103). If the request size is already small, it's possible that it is less than your kernel's SHMMIN parameter, in which case raising the request size or reconfiguring SHMMIN is called for. The PostgreSQL documentation contains more information about shared memory configuration. And I wonder if I should set shmmax or shmall and also if these 2 limits are total for all machine processes or per process? (i.e. should I allow a bit more for processes besides PostgreSQL)? Thank you Alex

CentOS 6: hostname and timezone
by Alexander Farber 04 Oct '11

04 Oct '11

Hello, I've purchased a new dedicated CentOS 6.0 / 64 bit server and have 2 minor problems please: 1) The "hostname" is reported as CentOS-60-64-minimal at CLI - eventhough I've edited /etc/hosts and changed the 2nd line: 127.0.0.1 localhost 176.9.123.123 preferans 2) Why is /etc/localtime a regular file? Should I maybe rm /etc/localtime ln -s /usr/share/zoneinfo/Europe/Berlin /etc/localtime Why isn't it done by the CentOS 6.0 install? Thank you Alex

Backup and restore for CentOS 5.5
by Denis 03 Oct '11

03 Oct '11

Hi - I have a NFS/NIS server environment running CentOS 5.5 on a Dell Optiplex 240. I would like to back it up and then move it to a new machine. Couple of questions: 1. This is an older computer Dell Optiplex 240 that I am unable to connect a USB drive to. In the "linux rescue" environment fdisk -l shows only /dev/hda but lsusb shows the three partitions that are on the drive. I would like to know how to connect the USB drive to the system so I can rsync or dd to the drive. 2. I was going to rsync a backup, excluding /proc, /sys, /dev and /tmp, either to a mounted USB drive or to a remote station. I know how to do that but how do I setup the drive up for the restore on the new computer. I have google'd but without success. I would think I need to format the hard drive, then run the LVM tools (<-very ignorant here), and install grub after all the files are in place (maybe mkinitrd too). Is there information avaiable to do this or would some be willing to provide what I would need to accomplish this. Thanks, -- Denis Becker

creating C6 xen VM and virt-install
by Mark Pryor 03 Oct '11

03 Oct '11

List, Now that Centos 6 is here, virt-install fails to launch an install for a C6 xen domU. The virt-install script is part of libvirt and is in package: python-virtinst.noarch the script, OSDistro.py, has a path hard-coded for a rhelX or centos VM install. IOW, ./images/xen is appended to the provided mirror URL to get the kernel/initrd.img pair needed for a netboot. Centos 6 repos don't have this subfolder in the images branch, but they have ./images/isolinux. Is there a reason that ./images/xen subfolder can't be created and populated with the boot pair from the ISOLINUX subfolder? I believe another RH clone project does this with good results. Help keep virt-install working with C6 and fix this, please. -- Mark

VLAN support?
by Les Mikesell 03 Oct '11

03 Oct '11

Are there any new tools in CentOS 6 to configure VLAN interfaces (where the switch passes multiple tagged VLANs over one physical link to the host) or is it best to edit /etc/sysconfig/network-scripts/eth?.vlan# files manually? -- Les Mikesell lesmikesell(a)gmail.com

PCI-E not supported in kernel 2.6.32-131.12.1.el6

Can you please help me in any way? do you know if is it maybe a bug or only unsupported hardware in new kernels?

Likely it's a misunderstanding of actual threats to websites, or using a IIS mindset to set requirements for Apache. I'll give Suexec+fastcgi a look and mod_ruid. Thanks for those suggestions While on subject of Apache security... Another request / idea was to have this CMS under development write user controls to .htaccess files to restrict download access to directories. Typically if I even allow any overrides, I set it so apache can only read .htaccess. My understanding of the more obvious implications is that if the web server can write to .htaccess so can any attacker, and then can easily inject malware or redirect the site to malicious content. Is there ever a case where it's safe to allow write access by apache to .htaccess? Does the below config for .htaccess in httpd.conf protect from this at all if write permissions were given on the file system? <Files ~ "^\.htaccess"> Order allow,deny Deny from all Satisfy All </Files> Personally I think that the CMS should handle authorization, and at then possibly rely on Apache for authentication. In the case of this CMS it will be authenticating against a campus SSO through CAS, but access has to be restricted based on user lists. - Trey
