Ben:
I'm trying to increase the number of open files with "ulimit -n nnnn", this
operation requires super user privilege.
Here is what I've found out so far.
It seems that modifying either /etc/profile or /etc/bashrc will not work for
my purpose since this runs under the user's UID.
Another option would of been allowing a "su" for /bin/ulimit by modifying
/etc/sudoers, unfortunately ulimit is built in to /bin/bash so this is not a
possibility for me.
I did find one hack that mentioned that you had to replace init with a
different version.
see /usr/share/emacs/20.7/etc/ulimit.hack for details, this hack modifies
the size of the files not the number of files. So this hack will not work
for me.
I'm thinking that maybe recompiling the kernel or bash would also do the
trick.
Another option is possibly modifying the settings via /proc file system, do
not know where to start on this one.
A third option is using inittab to launch a script that sets the desired
ulimit and then fires off migetty, or set this in ssh somehow; all the user
sessions will be via ssh.
I may be way off base since I've only have less than 3 months experience
with Linux\Unix. Can somebody on the list tell me if I'm way off base
here?
TIA
Richard

Thank you Ben, we have tried that here, it seems that /etc/profile runs in
the context of the user, I've been told that only the super user can
increase default settings.
I will keep you posted on what I find out.
regards
Richard

There is a 'ulimit' line in /etc/profile on my system (Redhat 7.1).
You could tweak that. Of course, I guess that it only applies to
those running Bash as a shell.
I've wondered myself if there is a way to set those at a kernel level.
Regards,
