mod_encoding
by a arias 11 Mar '11

11 Mar '11

I'm trying to setup the Janrain implementation of OpenID in a dev box running CentOS 5.5. The detect.php script is telling me, "Your web server seems to corrupt queries. Received , expected a=%26b. Check for mod_encoding." Does anyone know what package provides this? Thanks

mkswap - unable to relabel, operation not supported
by neubyr 10 Mar '11

10 Mar '11

Hi, I am getting following error on creating a swap fs. CentOS 5.5 {{{ mkswap: unable to relabel /srv/cloud/one/var/25/images/disk.1 to system_u:object_r:swapfile_t: Operation not supported }}} The selinux is configured in permissive mode.

Any reliable way to determine LVM snapshot creation time?
by Dr. Ed Morbius 10 Mar '11

10 Mar '11

We utilize LVM snapshots for some periodic maintenance. They're manually created and, usually, manually destroyed. But not always. So there's now a nightly script monitoring for open snapshots. Which raises the question of when a given snapshot was created. Absent good practices of, say, using sudo to create snapshots (leaving a /var/log/secure message), is there any reasonably reliable way to determine when an LVM was created? There's a timestamp on the /dev/mapper/<snapshot> file. I'm presuming that's somewhat useful for this purpose? Ah: just found /var/log/messages also indicates: lvm[2314]: Monitoring snapshot <name> lvm[2314]: No longer monitoring snapshot <name> ... which I think answers my own question. Posting here for Google's sake and/or discussion. -- Dr. Ed Morbius, Chief Scientist / | Robot Wrangler / Staff Psychologist | When you seek unlimited power Krell Power Systems Unlimited | Go to Krell!

Can anyone help me understand Apache Errors?
by Todd 10 Mar '11

10 Mar '11

LogWatch reports items like: Connection attempts using mod_proxy: 83.167.123.83 -> 205.188.251.1:443: 1 Time(s) 83.167.123.83 -> 64.12.202.36:443: 2 Time(s) Requests with error response codes 403 Forbidden 205.188.251.1:443: 1 Time(s) 64.12.202.36:443: 2 Time(s) 404 Not Found //jmx-console/HtmlAdaptor: 1 Time(s) /VINT_1984_THINK_DIFFERENT: 1 Time(s) /mobo.png: 1 Time(s) /player.swf: 1 Time(s) /robots.txt: 4 Time(s) Now, I know mod_proxy is turned off by default, but is there a way to "play games" with those that attempt a proxy connection? Like a ReWrite rule or some sort? For the 404's, Obviously these don't exist, but robots.txt so I am not sure why that has a 404. What are 406 errors? Some Googling say they are due to mod_security issues and that an .htaccess fix can turn it off. But I don't understand the issue and the solution to be honest. What am I missing? -Jason

Dell PERC H800 commandline RAID monitoring tools
by Dr. Ed Morbius 10 Mar '11

10 Mar '11

We're looking for tools to be used in monitoring the PERC H800 arrays on a set of database servers running CentOS 5.5. We've installed most of the OMSA (Dell monitoring) suite. Our current alerting is happening through SNMP, though it's a bit hit or miss (we apparently missed a couple of earlier predictive failure alerts on one drive). OMSA conflicts with mega-cli, though we may find that the latter is the more useful package. Both are pretty byzantine, the Dell stuff simply doesn't have docs (in particular: docs on how to interpret the omconfig log output). Ideally we'd like something which could be run as a Nagios plugin or cron job providing information on RAID status and/or possible disk errors. Probably both, actually. Thanks in advance. -- Dr. Ed Morbius, Chief Scientist / | Robot Wrangler / Staff Psychologist | When you seek unlimited power Krell Power Systems Unlimited | Go to Krell!

Just curious... CentOS4 lifetime tracks RHEL4 somewhat... Since RedHat has announced LTS (Long Term Support) for RHEL4, are there plans to extend the CentOS 4 support window?

We have created an next3 and patched e2fsprogs OpenNode / CentOS 5 / RHEL 5 rpms - installable from opennode-test yum repo. Provided next3 kernel module is currently built against RHEL5 OpenVZ kernel used in OpenNode - so installing this next3 rpm package on your CentOS 5 or RHEL 5 host will install also OpenVZ patched RHEL5 kernel and newer e2fsprogs package. Installation and usage instructions are provided by this howto document: http://opennode.activesys.org/documentation/howtos/next3-snapshots/ There is also simple next3 snapshotting automation script available for use with cron - usage and download link provided in howto document referenced above.

sata drives and controlers
by Michel Donais 10 Mar '11

10 Mar '11

I intend to replace fading SCSI drive by a SATA one. The motherboard is PCI and no SATA controller on board. So I need a SATA/PCI controller. Is there something wrong to do this kind of switch? Some told me that I won't be able to boot that drive. Loosing part of the SATA interface speed is not a decisive factor on this machine Is there are some prefered Linux SATA controller? Need experienced feedbacks. --- Michel Donais
