Re: [CentOS] No ulimit for user

Hi,

I'm trying to remove any limit on open files for a user; I've set username nofiles to unlimited in /etc/security/logins.conf, but now I get "could not open session" if I try to su to the user.

singhh - nofile unlimited

I think that is an invalid config, just set the limit to something really high

# ulimit -n unlimited -bash: ulimit: open files: cannot modify limit: Operation not permitted

Looks like somewhere around the 1 million mark is the max, can't imagine why anyone would have a system that would have so many files open.. The max I allow any user is 10,000 which seems reasonable.
