Swap & logout
by Sam Drinkard 10 Feb '06

10 Feb '06

Ran into something tonight I've not seen before. The system has been up for 20 days, and has not missed a beat of any sorts, even when getting beat on at a decent level. What my concern is, tonight I attempted to log out so X would restart, and from the looks of all the stuff on the screen (which never did reload gdm) was chock full of statements where swap had been exhausted, and processes were being killed off. The only way I was able to recover was to login via another machine and kill -9 the gdm process. Could not access any of the VT's at all. What I'm wondering is if swap is not being released, rather if processes are not being moved out of swap when the load decreased. From the looks of top top - 21:20:59 up 19 days, 23:07, 5 users, load average: 0.22, 0.24, 0.17 Tasks: 146 total, 1 running, 145 sleeping, 0 stopped, 0 zombie Cpu0 : 1.7% us, 0.3% sy, 0.0% ni, 98.0% id, 0.0% wa, 0.0% hi, 0.0% si Cpu1 : 0.7% us, 0.0% sy, 0.0% ni, 99.3% id, 0.0% wa, 0.0% hi, 0.0% si Cpu2 : 0.0% us, 0.0% sy, 0.0% ni, 100.0% id, 0.0% wa, 0.0% hi, 0.0% si Cpu3 : 0.7% us, 0.0% sy, 0.0% ni, 99.3% id, 0.0% wa, 0.0% hi, 0.0% si Mem: 2055916k total, 1199952k used, 855964k free, 50464k buffers Swap: 1052216k total, 64020k used, 988196k free, 781740k cached There seems to be plenty of swap free, even tho the cache is still OK. I didn't have the presence of mind to run any other tools to see the system behavior. Believe this is the first time I've had to kill gdm to reload and recover. Perhaps there is some tuning or tweaking I could do? The main processes are the wx model, which uses anywhere from 1.2 to 1.4G of memory, plus all the normal stuff you find on a workstation. Suggestions anyone? Thanks.. -- Sam Drinkard <sam(a)wa4phy.net>

CentOS friendly groupware
by Chris Mauritz 09 Feb '06

09 Feb '06

Just wondering what the consensus is around the list for a usable groupware product. It doesn't have to be as "fancy" as the integration between Outlook and Exchange...just simple calendaring, ToDo lists, document sharing, contact manager, etc. Has anyone tried opengroupware? It seems to do what I need, but doesn't support Chinese (which would make life a lot easier for my folks in China). Any suggestions would be greatly appreciated. Cheers,

poweroff when returning from standby
by Adrian Coman 09 Feb '06

09 Feb '06

Hi, I managed to make my Packard Bell EasyNote to standby (suspend to RAM), but I still have a problem: when I press the power button to return from standby, the system is restored but is immediately entering the poweroff procedure ... I don't know why. It's like I pressed the power button twice, which I didn't. Do you have any ideas of what could be wrong? Thanks, Adrian

Pressing "I" for interactive start-up does nothing
by Michael Chinn, CFO 09 Feb '06

09 Feb '06

Greetings, I'm trying to convert a Dell Inspiron 210B laptop into a sandbox using Centos4.2. The install went without incident but rebooting (starting) the first time the system hangs at "Initializing storage network" then says "disabling IRQ# 11" then goes no further. I've tried to press "i" and "I" to enter into interactive start-up (so I can check the log file) but I can't get interative start-up to turn over. Ideas? Thanks, Michael

09 Feb '06

Hi, I have a Packard Bell Easynote B notebook with CentOS 4.2 on it. I activated the standby option and it seems that entering the standby is OK (in a few seconds the display and hdd are closed, the power led is clipping). But when I try to restart the notebook, the hdd sems like it reads something, but the display remains blank. Also ctrl+alt+backspace or ctrl+alt+del don't have any efect. Did any of you succeded in making standby working with 4.2? Thanks, Adrian

Study Guide by Topics for Beginners
by Alain Reguera 09 Feb '06

09 Feb '06

Hi, I've been trying to organize my self, and has been making an order list, for beginners (as I am), of practical topics that should be studied to manage a communication node (ISP). Also, each topic should have referred books, urls and materials about it, in order of reading too. Here I ask you for some experienced help, to conform this, or some reference point where start on. The way you consider it must be done. My plan to learn is make a review of reading from start to end of it to get an overall idea of the topic (as a whole), and then go increasing the level of specification in each topic on each review reading. So the topics' ordering and the topics 'em selves are very important. Could this be right, any suggestion at this point would be highly appreciated too? So my starting list, 1. Introduction to Internet: The bases, and general ideas of where we are standing. At this point I started with Douglas E. Comer's Internetworking with TCP/IP Vol1 2. Firewalls: To grant security in place before start. 3. DNS: 4. Proxy: 3. Mail: 4. Web Server: 5. FTP Server: And of course CentOS-Linux to deploy all this. Any suggestion? Any idea? Anything will be appreciated.

MythTV on Centos 4
by Kirk Bocek 08 Feb '06

08 Feb '06

I'm starting a project to build a MythTV box for my living room. Anyone else currently working with MythTV on CentOS 4? Here are some of the gotcha's I've worked through so far: - I was originally planning on using KnoppMyth. But their CD appears to be only for i386. Without realizing it, the P4 CPU I picked is one of the newer ones with the x86_64 extensions. It won't boot i386. Thus, my plan B is going with CentOS4 x86_64 and installing from the ATrpms collection. Here's someone who's already doing this: http://umich2.com/archives/category/linux/mythtv/ - I picked up a cheap Radeon 7000 with TV out. Wrong! Various posts seem to say that the TV Out functionality is not supported by the X.org radeon driver. It *does* work with the vesa driver though. I just don't know if video and DVD playback will work with the vesa driver. Does anyone know? - The stock RedHat kernel does *not* have irda support enabled. I downloaded 2.6.13.2, enabled irda, and my motherboard's irda port is found and configured. We'll see if I can get it to work with the IR adapter in the nMediaPC case I bought. Kirk Bocek

Yum
by Peter Kitchener 08 Feb '06

08 Feb '06

Does anyone know how to get yum to ignore updates of a particular package? We use nagios 1.2 and yum wants to update it to nagios 2, how ever that breaks nagios when it does that. I want it to skip the updates of nagios and related packages till we work out the problems. Peter
