grsecurity forums

Hi i'm planing to open a shell business. I created u1bg, u2bg, u3bg, u4bg group. That means u1bg group has 1 process, u2bg has 2 processes ...
How can limit users processes using acl? Also i want to know how to limit users cpu usage because i don't want them to eat up all cpu. I want to know how to restirct their hdd usage (quota) to 20mb as well. If anyone can help I'll be pleased. Thanks.

no one ?

man limits
man pam
man quota

This is not really a grsecurity thing, grsec only enforces the limits (execve_limiting). The acls are used for restricting the use of files and/or directories, and capabilities.

If you are thinking about starting business it might be a good idea to RTFM first, or hire someone that is capable of doing so.
