Hello all,
I'm trying to raise the number of max open files a user has on my
system. I have been able to perform this operation on a Fedora Core
machine but when I try to implement on my Trustix machine, it seems to
not work. The following is what I did to try and raise the max number of
open files for the user joebob.
First I edited /etc/security/limits.conf to include the following lines:
joebob soft nofile 10000
joebob hard nofile 65536
I saved the file and then began to edit /etc/pam.d/login to include the
following line:
session required /lib/security/pam_limits.so
After saving the file, I issued an echo command to raise the max-files
on the system:
echo 65536 >/proc/sys/fs/file-max
I should then be able to logout and login as the user and issue the
command of ulimit -n 10000 and have it not produce an error.
Unfortunately I get an error and the max number of open files stays at
1024. The only way I have been able to raise the max number of open
files is too first login as root, issue ulimit -n 65536; then perform an
su - joebob; and finally issue ulimit -n 10000. This of course won't
work because I can't have users logging in as root that I can't trust,
but also the settings are not saved and need to be issued every session.
I realize that this is a session limit, but in FC it changes the max
number of open files upon login.
I checked the /etc/profile and the bashrc files(global and user-local)
none of these scripts are issuing any commands that pertain to ulimit.
I've even tried to perform a ulimit -n upon login as the user, but this
too also produces an error and leaves my max number of open files at 1024.
If someone could help me get to the bottom of this, it would be greatly
appreciated.
Thanks,
