I don't believe that you can dynamically set a ulimit value that is higher than the value currently in use... > Actually, I am not even sure limits.conf is being used since I have > the following lines in the file /etc/ssh/sshd_config > > UsePAM no > UsePrivilegeSeparation no PAM and ulimits are mutually exclusive...one does not affect the other. In my experience, if you want to use unlimited ulimit settings, you need to set them in the limits.conf file, and then start a new shell. You can also set lower limits on a user by user basis by adding ulimit commands to their .bash_profile files. -- Mike Burger http://www.bubbanfriends.org Visit the Dog Pound II BBS telnet://dogpound2.citadel.org or http://dogpound2.citadel.org To be notified of updates to the web site, visit: https://www.bubbanfriends.org/mailman/listinfo/site-update or send a blank email message to: site-update-subscribe@xxxxxxxxxxxxxxxxx -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
