Re: [mailinglists] Ulimit and max processes
Hi all, ok I am starting to get a bit further - If I log in on the console, I get a max processes of 7168 If I log in via telnet (installed for the test) I get 7168 If I have a cronjob that 'ulimit -a /tmp/ulimit' I get 7168 If I edit /etc/init.d/rc and add a 'ulimit -a /ulimit.txt' I get 7168 If I log in via ssh I get 256. The defualt PAM config uses /etc/security/limits.conf, and the default limits.conf is empty. I have changed the setting in limits.conf to 4000, AND rebooted, but no change in the 256. Does sshd do something stupid? Thanks Andrew -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

Re: [mailinglists] Ulimit and max processes
The box with 7168 is installed from a NetInstall Debian CD. The box with 256 is installed via PXE Boot using a copied filesystem from a box installed with the SAME NetInstall Debian CD. Both boxes are initially installed with WOODY, using the bf24 kernel. Regards Andrew Andrew: Did you upgrade the 256er-boxen from 2.2? Did you use make oldconfig or took you parts (patches) from the kernel before? -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

are you using the same kernel on both boxes? 2.4.x gives the 7168 limit, 2.6.x gives unlimited and 2.2.x gives 256 by default.

I have installed the SAME packages with dpkg --set-selections on two boxes with a self compiled kernel 2.4.25-p4smp. One has 256, one has 7168 WHERE is the 256 coming from - I have looked everywhere - even compared etc, lib dirs etc... I just dont understand!!!

/etc/sysctl.conf is empty on both boxes... Both are running woody. Very confused...

I am running two debian boxes with woody, but one has a ulimit -u (max user proc) of 7168, and the other of 256. (both as root) the difference does not appear to be in login.defs or /etc/security/limits. Does anyone have any ideas where I should look... diff -r /etc /etcother didnt seem to show any important diffeneces..

Re: [mailinglists] Ulimit and max processes
Hi! Do you have some security-enhancement packages installed on www01? I could imagine (i.e. don't know :-)) that stuff like selinux decreases umlimits on kernel compile time. Or maybe some uml or virtual hosts/machine package installed for hosting customers? rgds, j.
