I would like to:
- make a soft 64GB limit for resident memory (so inexperienced users will get their run-amok processes killed, but experienced users can raise the limit for memory hungry processes)
- raise the hard limit for nofile, but keep the soft limit at 1024 (so if a certain program needs more filehandles, the user can grant them, but run-amok programs will not get them).
As far as I can see, I should be able to do that in
/etc/security/limits.conf (or in
* soft rss 64000000 * hard nofile 50000 * soft nofile 1024
I can, however, not find a way reload these values with out rebooting. I have read that the values are reloaded when logging in; it works when I do
su - user but it does not work through
I have the pam_limits.so in /etc/pam.d:
/etc/pam.d/login:session required pam_limits.so /etc/pam.d/sshd:session required pam_limits.so /etc/pam.d/su:session required pam_limits.so
I have PAM in sshd_config:
I know I can set the values using
sysctl, but I would like to test that the
/etc/security/limits.conf is doing the right thing without rebooting.
How can I make sure that the values are being set when people login using ssh without rebooting?
