System hangs silently
by Fong Vang 19 Jan '06

19 Jan '06

I have a total of 20 CentOS 4.1 systems running on fairly new hardware. About 6 of them are experiencing strange hangs without any indication -- nothing in /var/log/messages nor on the console -- sometime within 10-30 minutes after a reboot. The systems still responds to ping but you can't ssh to it. At the console, you could type "root" at the user prompt but it hangs immediately after hitting enter. Memory scan of all systems show no error. Any idea how to troubleshoot this problem. The system's not responsive to do any troubleshooting and nothing abnormal is in the log. We running htis kernel: kernel-smp-2.6.9-11.EL.i686.rpm. Thanks for any help.

Well this doesn't sound in any way healthy. You're going to want to crawl through your apache logs and see if anything looks out of place. Odd GET or POST requests, SQL statements that don't look right etc. You might also want to look in /var/tmp and /tmp as well as in your DOCUMENT_ROOT, and remember to do an ls -la to show hidden directories. There are a couple of things out there that create a directory called ... in /var/tmp etc. You'll also want to look at your web software to make sure you're running secure versions etc. and make sure you've got all things updated. = = = = = = Based on this discussion http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=991 357 I think you have been hacked. The discussion talks about the author's clean up after his being hacked. Bruce

HPLIP
by Robert 18 Jan '06

18 Jan '06

First, has anyone successfully installed the HPLIP driver from HP in CentOS4? Second, does that driver really provide the toolbox which includes handy stuff like ink level monitoring? I got the source RPM (hplip-0.9.4-1.1.src.rpm) from an FC4 testing mirror, which rebuilt fine on this machine: . . . + umask 022 + cd /home/rj/rpmbuild/BUILD + cd hplip-0.9.4 + rm -rf /home/rj/rpmbuild/tmp/hplip-0.9.4-buildroot + exit 0 Executing(--clean): /bin/sh -e /home/rj/rpmbuild/tmp/rpm-tmp.54540 + umask 022 + cd /home/rj/rpmbuild/BUILD + rm -rf hplip-0.9.4 + exit 0 [rj@mavis ~]$ su Password: but would not install. [root@mavis rpmbuild]# rpm -ivh ./RPMS/i386/hplip-0.9.4-1.1.i386.rpm error: Failed dependencies: system-config-printer < 0.6.131.3 conflicts with hplip-0.9.4-1.1.i386 hpijs < 1:0.9.4-1.1 conflicts with hplip-0.9.4-1.1.i386 The conflict with hpijs is a no-brainer -- remove it because hplip is a replacement. But what about system-config-printer? I'm not too keen on dropping back to manually setting up printers. Any advice is welcome.

4.2 Lockup on Fujitsu-Siemens Primergy Econel 200
by CM 18 Jan '06

18 Jan '06

Hello everybody, I'm looking for some insights on reproductible lockups with this server so please bear the long description that follows: Installed the 4.0 Centos than yum updated it so it results a 4.2 Centos fully updated. During the instalation and update there were no cold boots. That's important because if (updated Centos or not) you cold boot the server it stucks at the "configuring hardware ... storage" step. It does not matter the kernel version but if i choose the SMP kernels it freezes just a little later on "configuring hardware ... audio" step.It freezes at the same spot without kernel panicking. I altered the rc.sysinit file so that at the configuring hardware step it does not load any modules. It passes (forcefully) the configuring hardware step but it freezes at the next "Configuring kernel parameters" step. There are no errors in the log as the k(logd) is not started at that point. For a change, i installed a FC2 and it's stable. However i want that Centos running! Please give me some advice. CM lspci output: 00:00.0 Host bridge: Intel Corp.

DHCP without network access
by Maciej Żenczykowski 18 Jan '06

18 Jan '06

Hi, I've got a box with CentOS 4.2 x86_64 which had no DHCP access for a few hours, now I can't ping it (I'm pretty sure the box is still up). I expect the DHCP lease has timed out and the box has lost it's IP, I was expecting it to reacquire it once the DHCP came back up (configuration problem) - but no luck. Is this a known problem? Any solution/workaround? (for now or for the future...) Cheers, MaZe.

gdm won't start
by Josh Kelley 18 Jan '06

18 Jan '06

I'm trying to set up a new CentOS 4.2 desktop, and gdm refuses to start. It blanks the screen, displays the swirling blue circle mouse cursor that appears to be an hourglass equivalent, then drops back to the console window. It repeats this several times then displays the following error: The display server has been shut down about 6 times in the last 90 seconds, it is likely that something bad is going on. I will wait for 2 minutes before trying again on display :0. xdm works, and I can access X Windows by running startx. Any ideas on how to troubleshoot? It's a fresh install with a few site-specific customizations, but I don't think that I've done anything that would intefere with gdm. It is a relatively minimal install, so it's possible that I'm missing some needed package. Thanks. Josh Kelley
