Hello,

Could You tell me guys, how can i set the limits listed below?

1) I know i can limit number of processes per user, but what about background processes? When i allow user to launch 20 processes, then he will be able to start at least few screen sessions. I would like all users, who belong to specified group, to be allowed only to launch only one background process (using &, and starting it in screen). I know this is possible, but got actually no idea, how to set that.

2) I wonder if it is possible to specify max. number of cron jobs per user?


Thanks in advance!

The difference between "foreground" and "background" processes exists only in the scope of the shell: the kernel nor the rest of userland cares about what a process attaches its file descriptors to. For applications that may help limit things anyway see http://www.linuxquestions.org/questi...35/#post579909.


As far as I know neither Vixie, Dillon or other cron daemon versions limit the amount of user processes.
