Mailing List Etiquette
by Johnny Hughes 18 Sep '06

18 Sep '06

OK guys and gals ... can we please stop all the fighting? When technical questions are asked, they should be answered. I lot of people on this list have something that a lot of newbies need ... experience. So answering a question with "RTFM" or "JFGI" is not going to impart any of your experience ... which is one of the things they need and want. Also ... if someone attacks you, you should not respond in kind, but should try not to flame or bait people. It take more than one person to get these things going, and just a little restraint on both people's parts could prevent problems. Can everyone who is a member of this list please read this document: http://www.gweep.ca/~edmonds/usenet/ml-etiquette.html Especially the section "I've been insulted! How should I respond?" Please, please, please ... can we be civil and not attack people personally. ALSO There is a forum at http://www.centos.org/modules/newbb/ It would be very good if people would post questions and answers there as well. Thanks, Johnny Hughes

Centos 4.4 Install bug
by Seth Bardash 18 Sep '06

18 Sep '06

To the Centos maintainers: We tried to install Centos 4.4 i386 (i686 / Athlon) on a Dual Opteron 254 Iwill DK8N MB, 1GB (4 x 256M) system with a 3ware 9500S-4 and 4 x 80 GB disks in a RAID 10 array. Both tries caused Centos to first kernel panic until we turned off IO-APIC in the BIOS. Both tries also only loaded the UP kernel and did not load the smp kernel on the machine. The smp kernel was not even installed on the machine. The BIOS see 2 cpu's and so did 4.3. There seems to be a CPU qty discovery problem during install. When the smp kernel is installed from rpm it works fine and even enables numa properly. We used the Net boot i386 iso image and loaded the machine from over the network. We then tried the x86_64 version with the same results. Any suggestions???

kernel-2.6.9-42.0.2 and LVM

Sep 13 12:18:56 sfe fsck: /dev/VolGroup00/LogVol00 is mounted. Sep 13 12:18:56 sfe fsck: e2fsck: Cannot continue, aborting. Sep 13 12:18:56 sfe rc.sysinit: Checking root filesystem failed I had updated the box a few days ago but I had not rebooted with the new kernel. After the reboot, I get the root filesystem is not marked clean message and also that it was not mounted read-only. I supplied the root password, remounted read-only, did the obligatory fsck and hit ctrl-D. Guess what? I get the same message! In addition, there were no error messages during the fsck to boot. Anyone else encounter this?

c4.4: OpenSSL Behavior: handshakes/ nrpe, snmpd, et al.
by karl＠klxsystems.net 17 Sep '06

17 Sep '06

Hello list, johnny, karanbir, rodrigo, william, all, Looks like some changes in 4.4 with openssl behavior I thought to ask about now that things have quieted down slightly since release. I use openssl with my nagios nrpe plugins, and now am getting a "could not complete SSL handshake". I will of course post to nagios list but first want to find out from centos side some key info re: 4.4/openssl [-if any, maybe no change at all?] since this all worked fine in 4.3, and it probably won't be too hard to do so in 4.4. : ) In doing an rpm -qa | grep openssl I am actually seeing two instances of openssl installed (Is that even possible?), when on a 4.3 box the output shows only one: ### box that's not doing proper SSL handshake openssl-0.9.7a-43.11 openssl-devel-0.9.7a-43.11 xmlsec1-openssl-1.2.6-3 openssl-0.9.7a-43.11 box that's working properly: # rpm -qa | grep ssl openssl-0.9.7a-43.8 xmlsec1-openssl-1.2.6-3 openssl-devel-0.9.7a-43.8 Background: 4.3 box with the issue was built with a custom RPM that we made that compiles apache with SSL. (different from the working box which is 4.3 and had a source compile and no ssl calls), Then I installed net-snmp, net-snmp-utils, and net-snmp-devel, (where in 4.3 all I had to do was edit /etc/snmp/snmpd.conf) which had a dependency for openssl, which it satisfied via yum. Perhaps the problem lies with the custom apache rpm? Our yum repo uses DAG. File perms are perfectly matched to working machine, so we know it's not that. -any ideas p.s. was snmp removed since 4.3? p.p.s. I never had to config tcpwrappers before in 4.3, should I do so now in 4.4? -karlski

RE: [CentOS] kbcached tuning on CentOS 4
by Justin Randall 16 Sep '06

16 Sep '06

Thanks for the response. The real concern comes from administrators or other less technical staff logging into the box, and getting concerned at the amount of memory used up. Although user education is always positively accepted, the general comfort level would be much higher if they could login to a host and not see that 98% of memory is in use. Regarding performance, this isn't much of a concern, although this host is intermittently hit with large work loads (which is why the kernel cache reaches the point of consuming all memory) which consume much memory, and another thought was that when these sporadic work loads proceed, there would be a slight performance hit waiting for free memory to be available as the cache is cleared. If this thought is misguided please let me know. Either way, what would be the correct method for tuning the kernel parameters? Justin. -----Original Message----- From: Daniel de Kok [mailto:danieldk@pobox.com] Sent: Monday, September 11, 2006 10:36 AM To: CentOS mailing list Subject: Re: [CentOS] kbcached tuning on CentOS 4 On Fri, 2006-09-08 at 10:31 -0400, Justin Randall wrote: > I had been chasing a potential memory leak until "sar -r", had > revealed that all the "mysteriously used" memory was actually being > taken up by the kernel data cache.

Linux is pretty smart about managing caches and buffers, and will grow/shrink the cache depending on the amount of memory. -- Daniel _______________________________________________ CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos

Pentium M in desktop system.
by Chris Weisiger 16 Sep '06

16 Sep '06

I have a Gigabyte 8S661FXMP motherboard. It had a P4 2.4Ghz processor in it. I have a laptop which cant be fixed and has a Pentium 4 M 2.8Ghz. I put the Pentium M in my desktop and it boots fine and runs fine, yet I have only been running it for about 30 minutes and shut it down. I have now run it for a complete 2 days without lock ups or anything. I have just been letting it idle, although I did do a defrag of a 120Gig hard drive which the hard drive was thoroughly fragged. So that was the first intensive thing done to my desktop with the pentium M processor. I runs at a cool 24 degress C. I did read that some laptops were socket 479 but i double checked my laptop and it is definitely socket 478. Both my desktop and laptop are socket 478. When I boot my system up, it does tell me that its a Mobile processor. What kinda issues would I need to look for as far as capatibility issues. I kinda took the situation as, it boots up and runs so it should be fine.
