Collecting data
by derleader __ 24 Dec '10

24 Dec '10

Hi, I'm developing C plugin for Centos which will be installed as kernel module. The problem is how to collect the data about: CPU Check – Utilization, Model, Number of Cores RAM Check – Total Memory, Free Memory, Memory Load HDD Check – Number of physical HDDs, Number of logical partitions, Total space, Free space Running processes – Total number of processes Logs – system logs such as error logs System uptime Users logged in and last login – total list of users Total network connections Check hardware parts model and number The kernel module will check the status of the OS every 5 minutes. What is the most efficient way to collect these data? Regards Peter

I have tried using Per replies in this thread, I modified the resolv.conf and /etc/sysconfig/network-scripts/ifcfg-eth0 files. The changes I made to those files did not work, and, if my memory is correct (it was several weeks ago), those files reverted to their original state. I solved this by assigning this Desktop PC a Static IP address. Since what happens, using DHCP, is, apparently, working the way it is designed to work, if and when I have a Laptop and am roaming around with it, I will fight this problem a lot harder. Thanks again, to those who replied! Much appreciated! Happy Holidays! Lanny

CentOS-testing php issues
by Rob Kampen 24 Dec '10

24 Dec '10

Hi List, I have been using the php 5.2.10 from the testing repo and note the following: the php-suhosin packages in testing do not match the php version > PHP Warning: PHP Startup: suhosin: Unable to initialize module > Module compiled with module API=20050922, debug=0, thread-safety=0 > PHP compiled with module API=20060613, debug=0, thread-safety=0 Also, does anyone know of a rpm for php-memcache and php-Fileinfo good for php 5.2.10? The rf ones are for base CentOS. TIA Rob

The case of the missing mail
by Anne Wilson 24 Dec '10

24 Dec '10

I became suspicious that I should have received a certain message, and reading pm.log I discovered that it had indeed arrived and had been allocated to /var/mail/anne, despite procmailrc telling it that MAILDIR=/home/anne/Maildir/ Any idea what might have caused this? It seems to have been working like this only in the last 24 hours or so. Anne -- KDE Community Working Group New to KDE Software? - get help from http://userbase.kde.org

Is ext4 stable on CentOS 5.5 64bit? I have an email server with a great deal of disk i/o and was wandering if ext4 would be better then ext3 for it?

IT8218 PCI IDE RAID CARD
by Keith Roberts 23 Dec '10

23 Dec '10

I have big problems with this card not working on Centos 5.5 If I run Parted Magic (kernel 2.6.32.11) from CD, then the IT8212F IDE PCI controller is detected OK, and I can access the WD hard drive on the controller, in r/w mode. Running Centos 5.5 I get lots of I/O errors at boot time, and cannot get r/w access to the drive from GParted. Any ideas what's happening, and why Centos 5.5 cannot get access to the IDE drive on the IT8212F controller card? Kind Regards, Keith Roberts -- In theory, theory and practice are the same; in practice they are not. This email was sent from my laptop with Centos 5.5

two cents or not two cents
by Sean 23 Dec '10

23 Dec '10

Hello Producers "Longevity of Support" is an attractive drawcard for CentOS if it means the exact opposite of Fedora's "short support cycle" that does not provide updating of infrastructural libraries for very long, libraries which newer versions of applications (like Firefox, Thunderbird, Opera etc) depend on and which wont install unless the libraries are also newer versions? But is that what it means -- ie that those infrastructural libraries (libpango, libcairo etc) are continuously updateable to fairly recent versions? If so, the problem is in reconciling that meaning with the reputation of CentOS to only support older versions of applications (eg Firefox-1.5, Thunderbird-1.0 etc). It does reconcile, of course, if the implications are merely that the CentOS user must compile and install the later versions of such applications from source, rather than having the luxury of pre-packaged binaries. It doesn't reconcile if there is some other critical reason why newer such applications just wont install. But which? I ask here because the profusion of vague mission statements and 'target-enduser-profile' claims that litter the internet re '*nix distros' seldom actually address those real issues. And hopefully someone can enlighten. My complex production & developement desktop takes months to fully port to a new OS (or OS-version), so OS updates to get library updates (ala Fedora philosophy) becomes increasingly untenable. Then there is a further question, I'm afraid. Since CentOS also does specifically target the profile of a so-called 'enterprise/server-user' what does that actually entail. Does it mean concrete security strictures which bolt down non-'root' users or does it merely mean the availability of SELinux (but which can be turned OFF)? For instance, (with SELinux OFF), can a user still: (a) su root via Kterm anytime? (b) Access services-admin anytime via Menu+Pam to control printers, modems, daemons etc? (c) compile (d) have 6 to 8 desktops running (e) call up 'konquerorsu.desktop' (root-konqueror with embedded root-Kterm) (f) have normal cron scheduling .......................................................... maybe more, but that's a start. Thanks for listening. Sean

changing background image
by Jerry Geis 23 Dec '10

23 Dec '10

I'm running centos 5.5 - 64 on Nvidia hardware. I am getting video from totem mixed in with my background image when I stop totem. If I change the background back to the default it does not seem to happen. However, as soon as I change the background to something else like ladybug.jpg and run totem fullscreen, then ask totem to quit with "totem --quit" the last video image is mixed in with my background. I did the standard (I think) way to change the background image: /usr/bin/gconftool-2 -t string --set /desktop/gnome/background/picture_filename "/usr/share/backgrounds/images/ladybug.jpg" su silentm -c "/usr/bin/gconftool-2 -t string --set /desktop/gnome/background/picture_filename '/usr/share/backgrounds/images/ladybug.jpg'" Is there something else I might be missing so the "still" of the video is not mixed in with my background? Thanks, Jerry

sendmail / logwatch relaying issue - driving me crazy
by Götz Reinicke - IT-Koordinator 23 Dec '10

23 Dec '10

Hallo, *<:-) may be I'm to tired to see the solution, maybe someone can give me a hint? I do have a couple of servers, sending the daily logwatch report to a central support email account. Some servers do have DNS A and CNAME records. On my mailserver relaying for the servers is allowed. Only one server drives me crazy, getting user unknown or releaying denied messages. Any idea, how to debug this issue? I'd be glad to fix this as a christmas gift. I could provide logmessages of course.
