Maybe someone will correct me, but I don't think that you can limit any of these things per-user in Linux (I seem to remember Alan Cox and Linus having an argument on whether such a feature is needed or not). You can, however, have per-process limits, and global limits. see the "ulimit" command (based on the setrlimit(2) system call). See also the /proc/sys/fs/file-* files. See nice(2) (and nice(1), renice(1)) on how to limit CPU usage of processes (again, processes and not whole users). -- Nadav Har'El | Monday, Jan 21 2002, 8 Shevat 5762 [EMAIL PROTECTED] |----------------------------------------- Phone: +972-53-245868, ICQ 13349191 |A conclusion is simply the place where http://nadav.harel.org.il |you got tired of thinking. ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
