Centos Forum is down??
by rock 05 Apr '09

05 Apr '09

Hi, I have joined the Centos forum a few days ago and still do not have my activation email. My user name and email address is in there but I cannot do anything until I activate. I have left a message with the webmaster and I have requested a lost password, but get nothing. I have checked all my email filters, spam boxes etc., and yet nothing. I am getting up to 100 emails a day at that address. Any ideas how I can get this up? Many thanks. oz :-)

Shadow passwords NOT md5'ed ?
by Frédérique Da Luene 05 Apr '09

05 Apr '09

Hello, I have a very weird problem on a CentOS 5.2 system. A few months ago, encrypted passwords in the shadow file were MD5'ed - allowing for long passwords, rather than only 8 characters max. Today, passwords are 3DES'ed only. No way to find how the system reverted to DES-encrypting. But what's more bothersome is we cannot get the system to go the MD5 way again, despite all our best efforts. Authconfig says this : pam_unix is always enabled shadow passwords are enabled password hashing algorithm is md5 So... where to look ? Tia, -- FdL

X session lockup (CentOS 4.7)
by Bart Schaefer 05 Apr '09

05 Apr '09

I just had a very odd incident with my session locking up, so I thought I'd describe it to see if it rings any bells with anyone. Background: I shut down my machine last night for Earth Hour, so the last thing I did before logging out was exit Firefox3, telling it to save my open tab state. When I turned the system back on and started FF3 again, it installed new versions of three plugins (I believe NoScript and Elasticfox but I don't recall the third) and then restored the session as expected. Not related to FF, but I also started up the "filelight" filesystem visualization app, which I don't normally have running, and it was still up on a different desktop while all the following was happening. This morning I opened a new FF3 window to browse CNN. I opened tabs on five or six stories from the front page and then went to read through them, closing each tab as I finished each story. (There were six other tabs open in the first FF window, so no more than 12-14 tabs in two windows total.) After closing the second such tab FF began responding very slowly, even to simply scrolling the window, and eventually stopped responding entirely (wouldn't even redraw when I dragged windows around). I popped up an xterm and ran "strace" on FF to see if I could find the problem, and lo and behold as long as strace was running FF recovered and responded fine, but when I stopped tracing it froze again. Unfortunately I lost the trace output because of what happened next, but I do recall that it was accessing /etc/localtime repeatedly and very frequently. I left strace running and went back to FF, hoping to see the tail of the trace at the moment FF locked up again. However, the next time FF appeared to be frozen I found that not just FF but the entire Gnome session was stuck. I was able to move the mouse and to Alt-F2 into a text console window, but nothing else responded. I went back and forth a few times between the text console and the X console attempting to diagnose (including killing the strace and sending a CONT signal to FF, because "ps" said FF was in stopped ("T") state), but after a few passes at that even Alt-F2 stopped working. Fortunately I have another computer here, so I ssh'd in and ran "killall -1 firefox-bin". This woke things up to the point that one of the pending Alt-F2 keystrokes was seen and the text console came up, but although I could then switch consoles again, nothing else in the X session was responding. I finally HUP'd gnome-session (which stopped everything else; I checked "ps" to make sure nothing that had been associated with that session was still running) and I have now logged in again and everything seems fine. FF restarted and restored the session from the time I killed it, and an strace of it now doesn't show any accesses to /etc/localtime at all. I find this all especially strange because the whole system had been restarted less than 12 hours before.

I found reason, why update wont go. I have installed much newer glibc, than what comes with 5.3. I needed that, because of couple radioamateur progs. Now have to think, how do I downgrade glibc. If I try remove, there's over 600 pagages, which have to remove and that's not good. Hmm... Jarmo

what requires lm_sensors?
by Kai Schaetzl 05 Apr '09

05 Apr '09

I found that lm_sensors got installed because of a dependency on my first Xen VM that I updated to 5.3. lm_sensors doesn't make sense in a VM. I thought, ok let's check after the update who wants it. However: rpm -q --whatrequires lm_sensors no package requires lm_sensors (same for --triggeredby with lm_sensors or the packages below) Trying to remove lm_sensors reveals these packages: Removing: lm_sensors i386 2.10.7-4.el5 installed 1.8 M Removing for dependencies: cacti noarch 0.8.7d-1.el5.rf installed 5.1 M net-snmp i386 1:5.3.2.2-5.el5 installed 2.8 M net-snmp-utils i386 1:5.3.2.2-5.el5 installed 342 k php-snmp i386 5.1.6-23.el5 installed 24 k But trying to remove any of them doesn't show a dependency on lm_sensors. How can I find out what triggered the installation of lm_sensors in the upgrade? Kai -- Kai Schätzl, Berlin, Germany Get your web at Conactive Internet Services: http://www.conactive.com

xen thinks guests exist but not show in list
by Neil Aggarwal 05 Apr '09

05 Apr '09

Hello: I tried to unsuccessfully install a guest on xen. It failed when it tried to connect to the display since I installed the OS without a graphical environment. When I do an xm list, I do not see the guest, but if I try to do virt-install with the same guest name, it tells me the domain already exists. I tried xm delete on the domain but that also tells me the domain does not exist. Any ideas?
