What can I do to UNDERSTAND why I can't reach centos.org (but everyone else can)?

What can I do to UNDERSTAND why, periodically, I can't reach www.centos.org (but everyone else can)? Every few months, http://www.centos.org just drops off for me and for me only. It's not the web site, because I can reach it via a proxy (e.g., TOR browser bundle) and other tests show it to be alive (e.g., http://www.downforeveryoneorjustme.com/centos.org or http://traceroute.monitis.com) But, for me, I just can't reach it by any means. Mike Easter kindly determined "centos.org does not echo ICMP or UDP pings, only TCP, and its associated netblock level3 doesn't echo UDP, but does echo ICMP and TCP." But, for me, this is what a traceroute returned just now on Centos: $ traceroute www.centos.org ... early hops removed ... 16 ae-6-6.ebr2.LosAngeles1.Level3.net (4.69.148.201) 211.850 ms ae-3-3.ebr3.Dallas1.Level3.net (4.69.132.78) 205.221 ms ae-6-6.ebr2.LosAngeles1.Level3.net (4.69.148.201) 207.392 ms 17 ae-3-3.ebr3.Dallas1.Level3.net (4.69.132.78) 128.453 ms ae-73-73.csw2.Dallas1.Level3.net (4.69.151.145) 160.451 ms ae-93-93.csw4.Dallas1.Level3.net (4.69.151.169) 160.437 ms 18 ae-83-83.csw3.Dallas1.Level3.net (4.69.151.157) 165.923 ms ae-1-60.edge3.Dallas1.Level3.net (4.69.145.8) 165.920 ms 178.414 ms 19 LAYERED-TEC.edge3.Dallas1.Level3.net (4.71.170.6) 241.537 ms 244.324 ms ae-3-80.edge3.Dallas1.Level3.net (4.69.145.136) 244.318 ms 20 * LAYERED-TEC.edge3.Dallas1.Level3.net (4.71.170.6) 244.291 ms 244.250 ms 21 * * * 22 * * * 23 * * * 24 * * * 25 * * * 26 * * * 27 * * * 28 * * * 29 * * * 30 * * * Here is a screenshot (modified to remove early hops) using mtr: $ mtr www.centos.org http://www2.picturepush.com/photo/a/12303130/img/12303130.png My related questions are: 1. What can I do (on Centos) to UNDERSTAND this problem? 2. Why does this problem happen every few months to me (and to just me)? 3. How can the net be this arbitrary and still work?

I have two servers running CentOS-6.3. On one of them I had (inadvertently) enabled the CentOS-CR repository. I noticed that there were a huge number of updates (over 400 packages) from this repository yesterday. I'm wondering if I disabled it now, would that cause confusion with subsequence updates? I'm also wondering if I leave it enabled, is the danger that the system will stop running negligible?

autofs and LDAP automount maps
by Tim Gustafson 01 Mar '13

01 Mar '13

Hi, We've been using autofs and LDAP automount maps for years now, and it has worked well. We run an environment that has CentOS, RHEL, Solaris and FreeBSD servers and clients. Historically, all our automount maps have looked like this: -vers=3 server:/export/home/& However, we're switching to NFSv4 and therefore we need to remove the -vers=3 flag. For CentOS 6.3, Solaris and FreeBSD clients, this causes them to mount with NFSv4, which is their default. However, the CentOS 5.x boxes are still defaulting to NFSv3 instead. Looking in /etc/sysconfig/autofs, I see a setting for "OPTIONS", but I'm not sure if those are mount options or what. Is there any way to cause CentOS 5.x to default to NFSv4 when using autofs? -- Tim Gustafson tjg(a)ucsc.edu 831-459-5354 Baskin Engineering, Room 313A

What I'm not sure about is how to move the date from the second PV to the first so I can then delete the contents of the drive and physically remove them from the system leaving me with only the two 3 Tb drives.

Newer SANE packages for 5.9 ??
by fred smith 01 Mar '13

01 Mar '13

I just got a Canon Canoscan LiDE 210 scanner, which the SANE project pages say works "completely" with Sane. but what isn't obvious without a lot of digging is that the version of Sane in EL5 isn't new enough. it works fine with what's on my eeepc (Fedora 17) but not Centos 5.9. I've been messing around with building sane from source, but have not been fully successful, yet, so thought before butchering my system any further I should ask if anyone has (or can point me to) newer Sane packages for EL5??

drbd and el6
by John R Pierce 28 Feb '13

28 Feb '13

hey, I have an application for drbd replication between a pair of EL6 servers, and I just realized that drbd is no longer built in. googling found me this blog on doing it using ElRepo distributions... http://www.broexperts.com/2012/06/how-to-install-drbd-on-centos-6-2/ is that still best practice? or is there a better distribution? or really... my application is a BackupPC server replicating its backup volume to a standby server (hey, no backup is really a backup, unless there is a backup of the backup, right?). is there a better/alternate way of maintaining a mirror of a backupPC volume than drbd... the backup volume is initially 8TB and could well grow to 3 times that over time. its stored on an XFS file system, under LVM, on striped raid6 volumes. -- john r pierce 37N 122W somewhere on the middle of the left coast

remote logging with rsyslog
by Nelson Green 28 Feb '13

28 Feb '13

This is a similar post to one I've made on the rsyslog list that has received no responses after four days, so I figured I'd try here since the problem seems to be CentOS specific. This is also my second attempt to send it to this list as the first seems to have never showed up. I am trying to test remote logging between two CentOS 6.3 systems and unable to get the client logs to show up on the server, using the RELP module. First of all, the client is a stock install of CentOS 6.3 running rsyslog v5.8.10. I inherited the server, but the change logging that we keep indicates it is pretty much stock too, and it is v5.8.10 as well. On the server, I added to /etc/rsyslog.conf: $ModLoad imrelp $InputRELPServerRun 20514 And restarted the daemon: sudo service rsyslog restart Shutting down system logger: [ OK ] Starting system logger: [ OK ] On the client, I added to /etc/rsyslog.conf: $ModLoad omrelp $WorkDirectory /var/spool/rsyslog $ActionQueueType LinkedList $ActionQueueFileName syslogfwd $ActionQueueMaxDiskSpace 10g $ActionResumeRetryCount -1 $ActionQueueSaveOnShutdown on *.* :omrelp:xxx.xxx.xxx.xxx:20514 And restarted the daemon: sudo service rsyslog restart Shutting down system logger: [ OK ] Starting system logger: [ OK ] Nothing ever showed up on the server, so I started going through the troubleshooting steps, which includes running the client in foreground mode and logging debug output: sudo service rsyslog stop sudo /sbin/rsyslogd -dn > /tmp/rsyslog.debug However, as soon as the service started in the foreground, log entries began showing up on the server. But when I stop the foreground service and restart it as a background service, the log entries quit showing up at the server. I can change things around so that tcp is used instead of RELP, and everything works that way. The problem is specific to using RELP in the normal background mode. I also tested the above RELP configuration on two Debian Wheezy boxes, each running rsyslog v5.8.11, and everything worked as expected. So the problem seems to be specific to CentOS with RELP. Has anyone gotten this to work on CentOS? Thanks, Nelson

Samba authentication against 389 DS
by Todor Petkov 28 Feb '13

28 Feb '13

Hello, I am using Centos 6 with 389 DS. Everything is working, I can authenticate my users against it etc. Now I am trying to make Samba authenticate against the LDAP by following http://directory.fedoraproject.org/wiki/Howto:Samba However, it seems that Samba does not read the 'password' value, but 'sambaNTPassword'. I wrote in 389-DS mailing list and they said, that there is no way to make Samba read the 'password'. So I must end with two password (Samba and "normal" one). I can not sync them, since crypt algorithms are different and I can not just copy/paste the password to sambaNTPassword. Did someone else had this issue? I need some file sharing software (can be even a web application), which can authenticate against LDAP, so all the people have one password for authentication. Regards,

VNC server not reponding to external requests
by Neil Aggarwal 28 Feb '13

28 Feb '13

Hello everyone: I tried following the instructions on this page to set up a VNC server: http://wiki.centos.org/HowTos/VNC-Server I can telnet to port 5901 from the machine itself: # telnet 127.0.0.1 5901 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. RFB 003.008 But, when I try to connect to it from the outside world, I get a connection timeout. My /etc/sysconfig/vncservers file does not have the -nolisten tcp nor the -localhost options so it should be configured to accept outside connections. Is there some default setting in the vncserver that I need to change to allow outside connections?

Hi All, I'm running our network with an 10/8 IPv4 subnets, with an SNAT catch all rule on the iptables firewall to the world. Is there a pratical way to log each connection?

CentOS 6.4 i386 and x86_64 Packages Available in the Continuous Release (CR) Repository
by Johnny Hughes 27 Feb '13

27 Feb '13

The CentOS-6.4 Packages for the i386 and x86_64 Architectures are now available via the Continuous Release (CR) Repository. The CR Announcements for CentOS-6.4 can be viewed here: http://lists.centos.org/pipermail/centos-cr-announce/2013-February/thread.h… More information about the CR Repository and how to install it is available here: http://wiki.centos.org/AdditionalResources/Repositories/CR As explained in the above link, we are still doing advanced QA testing on CentOS-6.4 and there may be some minor changes before the final release. This "opt-in" CR Repo process allows earlier access to our best effort packages now while we complete the final CentOS-6.4 QA processes, spin the ISOs and create an installable tree.

an rsync question
by m.roth＠5-cent.us 27 Feb '13

27 Feb '13

Is there any way to have rsync compare against a file with a *different* name? What I'd like to do is compare a vm - whatsit.img against a backup - whatsit.current, that's a symlink to whatsit.timestamp, and if different, *then* make the copy (which my script will then move to whatsit.newtimestamp, and change the symlink to point to the new one, then remove the old (or maybe save an older copy or two). So: backupdir \ whatsit.20130101 (backup of whatsit.img) whatsit.current -> whatsit.20130101 whatsit.20121201 After script w/ rsync backupdir \ whatsit.20130201 (backup of whatsit.img) whatsit.current -> whatsit.20130201 whatsit.20130101 mark

OT - 'IP' Security and Capturing Software
by Tom Brown 27 Feb '13

27 Feb '13

Hi After returning from a trip to discover the delights on being burgled i wonder if anyone has any experience of IP security camera(s) and software that can constantly record the stream? I have infrastructure that could store a few TB's of video data which should be plenty for a few weeks worth of recording thats attached to a CentOS 6 box. This would be purely for after the event viewing and in no way a preventative measure Anyone have any ideas? thanks

disabling lame server logging
by Robert Moskowitz 26 Feb '13

26 Feb '13

Continuing to 'clean up' my new server by reviewing logged messages. Researching a common one: Feb 26 07:30:29 onlo named[19336]: error (unexpected RCODE SERVFAIL) resolving 'foo.com/MX/IN': 1.2.3.4#53 I get the drift that my server has been directed to a 'lame server' and logs that fact. Supposedly I am to lookup the SOA record and contact the admin to fix this. What I really want to do is stop all these messages as I suspect I will not be able to do anything to fix the problem. So far what I have found is to add to my global logging section: category lame-servers { null; }; Is there a finer scalpel? I believe there are other lame server failures? Like 'RCODE REFUSED' and 'RCODE 15' (these are the 3 I see in my messages)? Can I block logging by RCODE, so as new ones appear I can learn what they mean before /dev/null ing them?

And then I went into conservative mode, as this impacted my firewall on Centos. Obviously overly conservative. I am learning more, and this time, for example, I am trying hard NOT to edit http.conf, instead to put some http.d/00-init-nn.conf files together so I can know as much as possible what I have added. I don't know yet if that can be done. I have done this on my test mail server. Will see if I can do it on my web server.

Re: [CentOS] UC centos 5 with xfs root?
by Rushton Martin 25 Feb '13

25 Feb '13

There are 3 issues here: Grub, the kernel and RedHat. 1) Grub won't run in an XFS /boot partition, but will happily run xfs_state1_5 to boot from an XFS root partition. 2) The kernel has supported XFS quite happily since at least 2005, I am looking at an SGI Propack 4 manual of February that year and it states that SLES 9 SP 1 contains the kernels with XFS support. 3) May be an issue. I'm just closing down an old Altix (2004 vintage) and that has always run XFS for everything except /boot. In the early days it used RedHat, but SGI's software included a patched kernel. Later on it ran SuSE Linux out-of-the-box. For compatibility I've configured the x86 machines with OpenSuSE 9 onwards as EXT2 for /boot and everything else on XFS. Sorry to mention SuSE on a CentOS NG, but that's where my experience lay at that time!

That's not completely true - XFS existed in the Linux kernel before EL5 - however, RedHat's support of XFS was added to the EL 5.4 kernel with a backport of a contemporary XFS release - and has had fixes added in subsequent EL5 kernels However, I would agree that unless you have a very good reason for staying with CentOS 5, then using CentOS 6 would be better - regardless of XFS support James Pearson _______________________________________________ CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos This email and any attachments to it may be confidential and are intended solely for the use of the individual to whom it is addressed.

Procmail/Formail problem on 6.3
by Fred Smith 25 Feb '13

25 Feb '13

Hi! In the process of making mysystem work again, having just done a reinstall of 6.3 x86_64. I have a considerable collection of procmail recipes for filtering mail in various ways, and since the upgrade none of 'em is working. procmail passes every mail thru spambayes, which gives back a rating on spamminess. this happens, so it's not as if procmail is simply punting. that is followed by tests for which mailbox it should go into, depending on the mailing list, or otherwise who it's from. these ARE NOT working. these recipes all use formail to append a header identifying the mail folder Procmail decided to use, and then the mail is appended to the mailbox. This has been working without problem for YEARS. but now, it all ends up in my main mailbox, where only those things that fail all the filters are supposed to go. aparently all the filters are failing. each filter is akin to this one: :0: * ^X-BeenThere: centos(a)centos.org | $FORMAIL -A"X-procmail: Centos-users" >>$HOME/Mail/centos which checks to see if it came from the centos mailing list, and if so should append a X"-Procmail: Centos-users" header then append the mail to $HOME/Mail/centos. Only it doesn't append the header, and it doesn't drop the mail in the centos mailbox. anyone out there got a clue? thanks!

Help Requested: KVM VM configuration on Centos 6.3
by Sanjay Arora 25 Feb '13

25 Feb '13

Hello I am trying to install KVM based VMs on my machine. First Timer...little idea on actually configuring related networking related issues. Am planning to follow this howto: http://www.howtoforge.com/virtualization-with-kvm-on-a-centos-6.3-server My trial machine is a server cum desktop with two network ports..eth0 is normally used for LAN & Internet access...eth1 is reserved for use with LTSP which is to be configured later. I need my VMs to be reachable from the internet by ssh & vnc etc. required ports will be forwarded from the Internet router. I propose to use subnet 10.0.1.0/24 for my virtual machines. Can someone please advise the content of bridge configuration file at /etc/sysconfig/network-scripts/ifcfg-br0, as given in the howto? The two bridges ltspbr0 & virbr0 shown below, are created by packages installed & not by me, so if any modifications are required in them...I need to know. Also, please advise if it is possible to get the VMs to use a 3G usb device for Internet access through the host machine Network Manage, in case Internet access through eth0 is down? Though this is not a priority at this stage, as I am just learning to use my first VM, but I'd like this feature if it is not too difficult. With regards.

Force CentOS 6.3 to discover new video card
by David McGuffey 24 Feb '13

24 Feb '13

I want to add a new video card that will drive multiple monitors. Current installation of CentOS 6.3 x86_64 is working well with the hdmi output of the motherboard. Once I install the new video card, how do I force 6.3 to discover and configure it? Seems with 6.0 and newer, system-config-display is gone and replaced with a combination of udev and xrandr. I'm not familiar with these and don't want to mess up a working system. Tips/pointers to some decent guidance/how-to docs would be appreciated. DaveM

Audio Editor
by Mark LaPierre 24 Feb '13

24 Feb '13

Hey All, I need some advice. I need an application, that will work with CentOS 6.3, that I can use to edit audio files. I've used Audacity in the past but it has compatibility issues with CentOS 6.3 that I would prefer to avoid. I've spent a couple of hours perusing the Add/Remove Software tool where I found the Gnome Sound Recorder, but that tool doesn't offer any editing capability as far as I can tell. Please, if you make a suggestion, also include the name of the repository where that application can be found. -- _ °v° /(_)\ ^ ^ Mark LaPierre Registered Linux user No #267004 https://linuxcounter.net/ ****

NFS mount auto remount in case of problems.
by Rafał Radecki 24 Feb '13

24 Feb '13

Hi All. I have a setup in which I have two servers serving nfs share. The nfs service is made highly available with pacemaker. When the primary server goes down the secondary starts nfs service. Service IP is floating between servers but they have NO "shared" storage/filesystem so NFS state/connection information in case of failover is lost. I have two clients. When the failover from primary to secondary occurs the mount is stale and I need to manually remount the share. Is there a way in linux/CentOS to automatically remount nfs share in such case? Or should I just write a script which (for example) check /proc/mounts and execute it from crontab? I am curious if it can be done with "standard" linux services (automounter?) ;) Best regards, Rafal Radecki.

problem building partitionable RAID-1 on Centos-6
by Fred 23 Feb '13

23 Feb '13

Trying to install Centos6 on my system (it's been running C5 for years). I've got a pair of drives, so I'm trying to use RAID-1. Previously I used a procedure where each partition was part of a separate RAID device, but this time I'm trying the HOWTO from the Centos WIKI on making a partitionable RAID pair. I've been having a lot of problems, but have also been working thru them. but t his latest one has me stumped, I'd appreciate some advice. Booting encounters a panic when trying to mount the RAID subsystem. you can see an image of it at users.rcn.com/fredricksmith/panic.JPG. Looks as if it's trying to boot from md127. there ain't no such critter, where'd it get the idea it could boot from there? or more importantly, how can I solve it? thanks! I may have to revert to the other method, but I figured this one was worth a try. Fred

Centos 6.3 and dovecot with an abrt problem
by Gregory P. Ennis 23 Feb '13

23 Feb '13

Everyone, I have a mail server running CentOS release 6.3 (Final) with 2.6.32-279.22.1.el6.i686 kernel that is reporting errors to me pertaining dovecot. I have appended the error message to this note. There is only one user that appears to generate this message, and it is generated to me by way of e-mail without a perceptible problem to the user which is not me. This particular user had an inbox greater than 2 gigs in size, so I asked him to move or delete unwanted files, which reduced the size of the inbox to 400 megs. Unfortunately, the abrt messages have continued. I did a google search on : "usr/libexec/dovecot/imap was killed by signal 6", but did not find much that I could use to help me debug this. Can any of you point me in the right direction. ' Thanks much!!!

I really should have caught that. So I was all ready to edit grub.conf and then slapped my hand. You TEST it out first, adding the command at boot time. ARGH! Once before (5+ years back) I had to add a kernel param and did it wrong and it was a big recovery challenge. No test and verify before making permanent. Whew. So I googled the param to get its format right, and it is iommu=off. Without that dash in front. But as I read up on this option, it does not sound like something I want to globally turn off just to stop a supposedly annoying message (if they have indeed worked around it, and my new DNS server is running with this OK). So I will test from booting and typing the option in without actually altering grub.conf. But if there is a way to just stop getting this message, that would be good too. thank you all for your help. > > https://www.google.com/search?q=linux+add+kernel+params > http://www.kernel.org/doc/Documentation/kernel-parameters.txt >
