Skype on CentOS??
by Doc Schneider 03 Mar '07

03 Mar '07

I'm just curious if Skype will work on CentOS? They have all kinds of FC rpms but which one to install? I'm running CentOS 4.4 I tried the Live CD just to test and it didn't want to find my sound card (Tried the sound card detection on the CD). But, I'm sure, that is a configuration issue and can be works out with ALSA. TIA, -- -Doc Lincoln, NE. http://www.genealogyforyou.com/ http://www.cairnproductions.com/

My current directory is lost in a bash shell
by Theo Band 03 Mar '07

03 Mar '07

This one puzzles me a lot: [thba@vink layout]$ nc script/xw_functions.ample NEdit: getcwd() fails: No such file or directory NEdit: getcwd() fails: No such file or directory [thba@vink layout]$ ll script/xw_functions.ample -rw-rw-r-- 1 thba thba 16829 Oct 25 16:59 script/xw_functions.ample [thba@vink layout]$ pwd /home/thba/workarea/colibri/design/ana/layout [thba@vink layout]$ /bin/pwd /bin/pwd: cannot get current directory: No such file or directory This error occurs in a bash shell on a regular basis. The funny thing is that I can just access the file by cat: cat script/xw_functions.ample works fine (I get the content of the file). To solve it for this shell I do this: [thba@vink layout]$ cd [thba@vink ~]$ cd - /home/thba/workarea/colibri/design/ana/layout [thba@vink layout]$ nc script/xw_functions.ample And it is fine again. This is a home nfs share mounted with these options: arend:/export/home /home nfs proto=tcp,nfsvers=3,bg,defaults 0 0 Both on the NFS server as on this client I see any errors or warning in any log. All kind of applications are affected by this problem so I need to dig into this deeper. Server: FC3 client: CENTOS4.4 Any help is appreciated. Thanks, Theo

Swap Considerations
by Mike McCarty 03 Mar '07

03 Mar '07

I am considering installing CentOS 4.4, and am interested in how best to set up. I have been using FC2 and helping administer a Debian machine for a few years, but do not consider myself a Linux guru. My current set up uses a /swap partition which is 2x my memory size mem = 256 MB $ sudo /sbin/fdisk -l /dev/hda6 76506 77545 524128+ 82 Linux swap I'm interested in the use of a file for swap, as I hear that there is now no speed penalty for that. I use ext3 for my partitions. I'm also interested in whether it be reasonable/desirable to make /home, /tmp, and /var be on a separate partition. I have heard arguments on both sides, some claiming that with ext3 the system won't become unbootable because of /tmp filling up. Anyone care to weigh in?

Build a special RPM
by Mário Gamito 03 Mar '07

03 Mar '07

Hi, I want to build a single RPM that has more than one software in it and a different name from them. Let's imagine for the sake of example that i want to make an RPM called databases.rpm that installs both MySQL and Postgres. How can i do this with a single spec file ? I've googled for an hour or two and found no info about this issue. Can someone enlighten me, please ? WarmRegards, Mário Gamito

kernel issues
by William Warren 03 Mar '07

03 Mar '07

I just had to revert from the latest kernel back to .08 due to panics. i used rpm to remove the .10 kernel. However i know can't get the smp version of the .10 kernel to install via yum.

RE: [CentOS] Virtualisation
by Mark Hull-Richter 02 Mar '07

02 Mar '07

How memory-intensive is VMWare workstation? I have a P4 3.0GHz with 1/2Gb of memory at home - is VMWare going to be a total drag on the system or is it lightweight enough that I can still run (as opposed to walk or crawl)? I run VMWW at work, but that's a Pentium-D with 2Gb of RAM, and top shows vmware using 199m virt, 1.1g res and 1.1g shr - not sure what that means (but it looks like bad news for the home situation...). Thanks.

errors
by William Warren 02 Mar '07

02 Mar '07

for most of you this is going to be simple for me it's new: I have a ssytem that suddenly throws this error after the most recent kernel upgrade: http://img172.imageshack.us/my.php?image=errordh4.jpg I'm thinking i should be able to back the sytem off to the previous kernel. How do i do this since it won't boot? -- My "Foundation" verse: Isa 54:17 No weapon that is formed against thee shall prosper; and every tongue that shall rise against thee in judgment thou shalt condemn.

Re: [CentOS] What is cached swap?
by C. Halstead 02 Mar '07

02 Mar '07

That number is the amount of physical memory that is being used by cache buffers for your filesystems. It has nothing to do with swap. Try this trick: Run top and note the value of 'cached' run 'dd if=/dev/zero of=~/test bs=1M count=256' Run top again and see that 'cached' has grown by 256M remove the file ~/test Run top again and see that the value of 'cached' has dropped by 256M With that said, there is a 'SwapCached' value reported in /proc/meminfo that represents the amount of swap space used by pages that are also in physical mem (like if something was swapped out and then back in). The VMM doesn't clear those swap pages unless they are needed or the process terminates. Cheers, -chris --- C.

setting up incoming PPP on centos 4.4
by fredex 02 Mar '07

02 Mar '07

hi gang! I'm interested in setting up incoming PPP on a system at work that has a fresh (not upgrade) Centos 4.4 on it. All the documentation I've found for that shows using mgetty to do it, and seems pretty straightforward. However, that machine doesn't have a binary named mgetty anywhere. It does have a mgetty-sendfax RPM installed, but it does not provide a binary named mgetty. "yum -list available | grep -y getty" shows no additional packages I could use to obtain it. so, how does one set up incoming PPP on Centos 4.4? (I've searched the RH knowledgebase and all I found there that came close was a very nice document on doing it on RHEL 3, which shows how to do it with mgetty. Catch 22.)
