When I issue sudo tail -f/var/log/syslog in order to try and track down an external drive problem I get the following: Jan 11 07:56:00 kernel: [17179663.076000] atkbd.c: Unknown key released (translated set 2, code 0x81 on isa0060/serio0). Jan 11 07:56:00 kernel: [17179663.076000] atkbd.c: Use 'setkeycodes e001 <keycode>' to make it known. Jan 11 07:56:00 kernel: [17179663.084000] atkbd.c: Unknown key pressed (translated set 2, code 0xd9 on isa0060/serio0).

Jan 11 07:56:11 kernel: [17179674.012000] atkbd.c: Use'setkeycodes e059 <keycode>' to make it known. I have no idea what this means. atkbd presumably means AT keyboard? Can anybody translate the rest and point me at what might be wrong with my keyboard setup? By the way ,the server is CentOS 5.3 x86_64, and kernel version is 2.6.18-128 Thanks....

How much maximum memory will CentOS 5 support? I know it's not 16 GB!
by Aleksey Tsalolikhin 23 Feb '11

How much maximum memory will CentOS 5 support, please? The product info page at http://www.centos.org/product.html says 16GB, but I am running 80 GB RAM right now and seeing 80 GB in top. I see the same 16 GB limit on the RHEL page: http://www.redhat.com/rhel/compare/#note_4 The server hardware is capable of 192 GB RAM and I want to add memory, but want to be sure the OS will support it. Is anybody running CentOS 5 or RHEL 5 with 192 GB or more, please? Best, -at

problems with createrepo
by Janez Kosmrlj 22 Feb '11

22 Feb '11

I run a local repo for our company's packages. Since yesterday we have problems with creating the repo files. When i run "createrepo --update -s sha rpmdir" i get the folowing error: File "/usr/share/createrepo/genpkgmetadata.py", line 249, in ? main(sys.argv[1:]) File "/usr/share/createrepo/genpkgmetadata.py", line 223, in main mdgen.doPkgMetadata() File "/usr/lib/python2.4/site-packages/createrepo/__init__.py", line 368, in doPkgMetadata self.writeMetadataDocs(packages) File "/usr/lib/python2.4/site-packages/createrepo/__init__.py", line 532, in writeMetadataDocs self.primaryfile.write(po.xml_dump_primary_metadata()) File "/usr/lib/python2.4/site-packages/yum/packages.py", line 1032, in xml_dump_primary_metadata msg += misc.to_unicode(self._dump_base_items()) File "/usr/lib/python2.4/site-packages/yum/packages.py", line 866, in _dump_base_items msg = """ UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 83: ordinal not in range(128) I didn't change anything on the server and it fails on packages that are more than a year old. It usually fails on package number 200-206. When i move the supposedly broken package to a new directory and run createrepo on that directory, then createrepo finishes OK. I googled a bit, but i couldn't find anything useful. Has anyone on this list seen something similar and what was the problem. thanx in advance Janez

funding

Maybe what Centos needs is a bridal registry. Here in the US, an engaged couple can tell their friends what they'd like to be given as wedding presents. They do this by listing items in a registry, in various stores around town. Anyway, the idea is, post stuff you need in a list on your site. Say you need 20 hard drives, or a particular power supply, or whatever items that get consumed in day to day operations. Just list what's needed, who needs it, and whatever info. It doesn't have to be hardware either - just something everyone can agree is OK to list. People visiting the site can look and decide if it's possible to contribute something - even if it's only one new hard drive of the type needed. Or maybe a canister of Columbia's finest coffee. (although I supposed consuming donated foods of any kind from unknown persons is a risk) And should a contributing member have a hardware failure on his own personal workstation, why not ask the world for some charity in return for his/her efforts? Just list what you need, what it is to be used for, and see if we like you enough to give it to you. 'Contributing members' meaning those known to the community, verifiable, and who are putting in the hours, or whatever efforts. And I'm thinking cash donations should be frowned upon because money can be so easily subverted to doing bad things in the world.

iptables question.
by Bill Campbell 22 Feb '11

22 Feb '11

We use a home-brew system similar to fail2ban to block traffic from IP addresses which appear to be doing Nasty Things(tm). The main thing our system does that fail2ban doesn't is to use a central DNSRBL we maintain allowing it to immedatiately ban listed IP addresses the first time they make an attempt to connection without waiting for them to hit a sufficient number of times to bring up the block. This system sends e-mail messages to our security alias whenever a blocking even occurs, either from tcp_wrappers or swatch log watcher. My problem is that occassionally an IP addresses doesn't appear to be blocked as we continue to see the e-mail messages after the blocks are in place. Most frequently these occur from courier-imap failed login attempts, less frequently from sshd. To start, iptables is initialized by setting up a named rule set, say on eth0: # these two set up the rule set. iptables -N csblocks iptables -A csblocks -j RETURN # now add it to input, check csblocks on all new connections. iptables -i eth0 -m state --state NEW -j csblocks #Insert block IP address 1.2.3.4 as first rule in the set. iptables -I csblocks 1 -s 1.2.3.4 -j DROP # now add a rule to prevent IP forwarding on gateway machines. iptables -A FORWARD -s 1.2.3.4 -j DROP # for good measure, null route the IP route add -host 1.2.3.4 reject With all that incoming attempts still seem to get by for a few IP addresses, but certainly not all. Can anybody point out what I'm doing wrong, or why this may happen? Bill -- INTERNET: bill(a)celestial.com Bill Campbell; Celestial Software LLC URL: http://www.celestial.com/ PO Box 820; 6641 E.

java-1.6.0-openjdk.x86_64 keeps clobbering logging.properties
by Jason Pyeron 22 Feb '11

22 Feb '11

It appears that the rpm does not list the logging.properties as a config file, as such every time yum updates the file get overwritten. /usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/jre/lib/logging.properties For now I have a cron job to replace it. Any suggestions? -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- - - - Jason Pyeron PD Inc. http://www.pdinc.us - - Principal Consultant 10 West 24th Street #100 - - +1 (443) 269-1555 x333 Baltimore, Maryland 21218 - - - -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- This message is copyright PD Inc, subject to license 20080407P00.

Basic Bash Script Question
by James Bensley 21 Feb '11

21 Feb '11

I'm stuck trying to work this one out and my Google skills are apparently lacking today. This is a test bash script; #!/bin/bash do something | tee a.log if [ $? -ne 0]; then echo broken fi The problem with this script is $? contains the exit value of the tee command, but I want to check the exit value of whatever command I put in place of 'do something'. How can I achieve this without loosing the tee operation, as 'do something' maybe a long running command with a lot of output like rsync? I don't want to; result=`do something` if [ $? -ne 0... .... fi echo $result As that won't output anything until the script has finished (the reason for the tee is that this script will be a scheduled cron tab but it may be run interactively sometimes also). Thanks for reading :) -- James. http://www.jamesbensley.co.cc/ There are 10 kinds of people in the world; Those who understand Vigesimal, and J others...?

CentOS 5.5 Java Process Death
by Martin Hewitt 21 Feb '11

21 Feb '11

Hi all, I'm running CentOS 5.5 Final, Java version "1.6.0_17" OpenJDK Runtime Environment (IcedTea6 1.7.5) (rhel-1.16.b17.el5-x86_64) OpenJDK 64-Bit Server VM (build 14.0-b16, mixed mode) installed via Yum. We have a java application, packaged as a jar, running on our servers which, periodically, crawls RSS feeds and writes the articles to a database. Randomly, and seemingly without cause, these processes will die, not through the application exiting, or due to my killing it, but due to something that seems to kill without leaving a trace. My first step in diagnosing this was to log all output from the application, as well as sending stderr and stdout to a logfile, but none of these output logs contain anything that would indicate why these processes have died. My next instinct was the kernel-level out of memory killer, but the system is never low on memory (8GB installed, routinely showing 6.5GB in free cache) and usually has somewhere between 1GB and 3GB of memory free at any given point in time. I next thought the system could be hitting bad memory, segfaulting, and killing the process because of that, but I've mirrored the system on an identically configured server in a different datacentre, and the processes are still being killed. The java virtual machine does trigger JVM core dumps on exit, so the process is being killed by something, but the JVM dumps don't have any useful information. My question is: does anyone know what might be causing it, and where I should start looking to diagnose the cause? Thanks.
