New firefox causing anyone else problems - CentOS 4.X?
by William L. Maltby 31 Mar '08

31 Mar '08

Looks like Firefox may be getting another update soon, if my problem is not atypical. Prior to the latest, had NP for *months*. Anyone else seeing any problems? BTW, running the recent Java console from sun that was detailed in another thread a week or two back with Firefox. Had NP prior to the latest update, if that offers any useful info. Would like to test the openjdk for us if it's applicable to 4.x. If not, I can still test it on the 5.x machine. # uname -a Linux centos01.homegroannetworking 2.6.9-67.0.7.EL #1 Sat Mar 15 06:19:12 EDT 2008 i686 athlon i386 GNU/Linux >From rpm -qa --last: krb5-workstation-1.3.4-54.el4_6.1 Thu Mar 27 14:14:55 2008 krb5-devel-1.3.4-54.el4_6.1 Thu Mar 27 14:14:51 2008 krb5-server-1.3.4-54.el4_6.1 Thu Mar 27 14:14:49 2008 firefox-1.5.0.12-0.14.el4.centos Thu Mar 27 14:14:39 2008 krb5-libs-1.3.4-54.el4_6.1 Thu Mar 27 14:14:16 2008 jre-1.6.0_05-fcs Mon Mar 17 09:13:36 2008 kernel-smp-devel-2.6.9-67.0.7.EL Sun Mar 16 06:02:20 2008 kernel-hugemem-devel-2.6.9-67.0.7.EL Sun Mar 16 06:01:42 2008 kernel-doc-2.6.9-67.0.7.EL Sun Mar 16 06:01:35 2008 kernel-2.6.9-67.0.7.EL Sun Mar 16 06:01:21 2008 kernel-devel-2.6.9-67.0.7.EL Sun Mar 16 06:00:00 2008 >From the messages log: (sorry about the wrapping) Mar 30 14:53:40 centos01 kernel: general protection fault: 0000 [#1] Mar 30 14:53:40 centos01 kernel: Modules linked in: loop vfat fat radeon md5 ipv6 parport_pc lp parport autofs4 i2c_dev i2c_core sunrpc ipt_REJECT ipt_state ip_conntrack iptable_filter ip_tables dm_multipath button battery ac sd_mod usb_storage scsi_mod uhci_hcd ehci_hcd snd_via82xx snd_ac97_codec snd_pcm_oss snd_mixer_oss snd_pcm snd_timer snd_page_alloc snd_mpu401_uart snd_rawmidi snd_seq_device snd soundcore 8139too mii floppy dm_snapshot dm_zero dm_mirror ext3 jbd dm_mod Mar 30 14:53:40 centos01 kernel: CPU: 0 Mar 30 14:53:40 centos01 kernel: EIP: 0060:[<0028f705>] Not tainted VLI Mar 30 14:53:40 centos01 kernel: EFLAGS: 00010206 (2.6.9-67.0.4.EL) Mar 30 14:53:40 centos01 kernel: EIP is at 0x28f705 Mar 30 14:53:40 centos01 kernel: eax: f4360de0 ebx: f4360de0 ecx: 0028f705 edx: e0125fa0 Mar 30 14:53:40 centos01 kernel: esi: 00000145 edi: f634ce00 ebp: 00000003 esp: e0125f48 Mar 30 14:53:40 centos01 kernel: ds: 007b es: 007b ss: 0068 Mar 30 14:53:40 centos01 kernel: Process firefox-bin (pid: 21366, threadinfo=e0125000 task=f4499870) Mar 30 14:53:40 centos01 kernel: Stack: c0182962 e0125f6c 00000009 f634cde0 00000003 e0125fa0 f634cde0 c01829e5 Mar 30 14:53:40 centos01 kernel: e0125f70 e0125fa0 00000000 00000000 f634cde0 0c0e5958 00000009 c0182c09 Mar 30 14:53:40 centos01 kernel: 00000003 00000bb7 f634cde0 f634cde0 00000000 fffffff4 c018201d cd499000 Mar 30 14:53:40 centos01 kernel: Call Trace: Mar 30 14:53:40 centos01 kernel: [<c0182962>] do_pollfd+0x47/0x81 Mar 30 14:53:40 centos01 kernel: [<c01829e5>] do_poll+0x49/0xab Mar 30 14:53:40 centos01 kernel: [<c0182c09>] sys_poll+0x1c2/0x279 Mar 30 14:53:40 centos01 kernel: [<c018201d>] __pollwait+0x0/0x94 Mar 30 14:53:40 centos01 kernel: [<c01291d1>] sys_gettimeofday +0x53/0xac Mar 30 14:53:40 centos01 kernel: [<c031d8eb>] syscall_call+0x7/0xb Mar 30 14:53:40 centos01 kernel: Code: Bad EIP value.

the "official" lightweight desktop environment for CentOS?
by Florin Andrei 31 Mar '08

31 Mar '08

I want to build a dedicated MythTV box using CentOS5. I need a lightweight desktop environment, something extremely simple that does not use much memory. Gnome and KDE use way too much memory and are too complex for what I want to do. The system will login automatically to a certain account after booting up. After the automatic login, it will start immediately the MythTV frontend full-screen. If the frontend dies, the desktop needs to logout / log back in automatically. No other application will run on this machine, only mythfrontend. There will only be one account. Think of it as a single-purpose appliance, not a regular computer. Whatever I use as the desktop environment, it needs to be pretty standard - either included in the distribution proper, or in one of the major repositories. It must be very trivial to enable, with no hacking required to the OS. It must play well with mythfrontend, I don't need any compatibility issues. It must be a stable, reputable software. Which desktop environment would you recommend based on the requirements? -- Florin Andrei http://florin.myip.org/

Weird that it causes the driver module not to load. The original owner suggested that might be the problem so, after trying a CentOS 5.0 kernel and building and trying a 2.6.24.4 kernel I decided to crack the case. I pulled the cable for the case's front audio and mic off the motherboard and tried with that configuration. The good news was I no longer got the error documented in my earlier e-mail but still no sound. The case's front panel audio had two different connectors so I decided to try the other one and suddenly I had sound. No idea what the difference is between the two connectors. What's really strange is both front audio connection jacks are keyed correctly for the front panel audio out on the motherboard. It's just one works and the other doesn't.

Help in troubleshoot cause of high kernel activity
by Noob Centos Admin 30 Mar '08

30 Mar '08

Hi, I had been experiencing a problem on our dedicated server running Centos 5, and unable to successfully track down the problem. Since about 6 days ago, I noticed a spike in load/CPU utilization which went from a typical 0.2x-0.3x to 3.x. At the same time, average traffic also went up and so did the log usage. Prior to this, the server was working fine and there had been no changes to the configuration. Initially, I narrowed it down to the mail system. Exim was generating significantly more log data than usual. This was eventually narrowed down to apparently our server and another server playing ping pong between two users who coincidentally were on vacation and had both their mailboxes filled. Thus it caused an endless loop of "Message Undelivered" and "Auto-reply". Once this was identified and cleared up, I had expected things to go back to normal. However, load/traffic remained high. Looking at "top" output, I noted that %sys was as high and often much higher than %user. However, individual process %CPU just didn't add up to the total top was reporting. Top reports 160~170 sleeping tasks and only 4 active most of the time, which was largely exim then httpd/mysql/php. top Snapshot ========== top - 17:25:03 up 7 days, 19:16, 1 user, load average: 2.03, 2.84, 3.04 Tasks: 168 total, 4 running, 164 sleeping, 0 stopped, 0 zombie Cpu(s): 26.5%us, 50.3%sy, 0.0%ni, 16.6%id, 6.1%wa, 0.0%hi, 0.5%si, 0.0%st Mem: 1915208k total, 1880256k used, 34952k free, 142100k buffers Swap: 16777208k total, 66140k used, 16711068k free, 1276564k cached iostat Snapshot ============ avg-cpu: %user %nice %system %iowait %steal %idle 18.96 0.00 25.57 5.16 0.01 50.30 Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn sda 54.19 63.31 2460.80 42689802 1659234904 sdb 55.12 76.41 2460.80 51521720 1659234904 md1 315.95 139.72 2442.00 94207644 1646554216 md0 0.01 0.00 0.02 1422 14736 dm-0 39.13 65.85 292.50 44399402 197219496 dm-1 267.18 36.18 2110.08 24398010 1422756072 dm-2 9.64 37.68 39.42 25408576 26578648 fd0 0.00 0.00 0.00 16 0 sr0 0.00 0.00 0.00 136 0 Searching around for ways to interpret the output, I tried sar/iostat and essentially, the information off the net indicates there wasn't a disk problem, %io was relatively low and mdadm shows the RAID 1 disks working perfectly fine. Since %sys is consistently highest, it appears that the kernel was doing something outside of norm. The problem is I have no idea what else to do to determine what "something" is. I've looked at netstat and there doesn't appear to be excessive connections, logwatch summary also does not appear to give any clue as there are no records of unusual failed log in attempts. Please advise what else can I look into or check. Thanks in advance!

A few questions regarding CentOS (5.0)
by Morten Nilsen 30 Mar '08

30 Mar '08

Hello list, I'm a former Trustix User (were active in that community since the very first betas), and now that my dear distro is dead, I'm looking to make a switch.. Several people recommended CentOS, so I decided to give it a spin.. I installed one new server with 5.0 a few months back, and I do have a couple of questions.. - Why does the screen flicker on and off several times during boot and when logging in? - Why does floppy.so get loaded? I have no floppy, and having floppy.so loaded while installing certain packages is dreadfully slow. - When I chose a pure console environment, without any X11 stuff, why did a bunch of gnome packages get installed? - Is it possible to get a php-mssql package? -I need this if I'm going to use CentOS at work.. I think that's it for now.. -- Cheers, Morten

World Writable Files
by Anne Wilson 30 Mar '08

30 Mar '08

I'm curious. Why are so many system-generated files world-writable? On my Mandriva laptop, every day I get warnings that world-writable files are found in /tmp, /far/lib/ /var/run/ and /var/spool, and every day msec reports that it has changed the mode of several files in /var/log/. Why are they created like that? Anne
