Special Forums Cybersecurity Limit CPU and RAM utilization for new user in RedHat Post 302704131 by bakunin on Friday 21st of September 2012 04:48:24 AM

You do not need to: a "hard limit" is like a wall: once set, it can't be changed (by the user, that is). A "soft limit" is different: it is set, but the user can change it (up to the maximum of the hard limit) himself.

I hope this helps.

NAME
plimit - get or set the resource limits of running processes SYNOPSIS
plimit [-km] pid... plimit {-cdfnstv} soft,hard... pid... DESCRIPTION
If one or more of the cdfnstv options is specified, plimit sets the soft (current) limit and/or the hard (maximum) limit of the indicated resource(s) in the processes identified by the process-ID list, pid. Otherwise plimit reports the resource limits of the processes identi- fied by the process-ID list, pid. Only the owner of a process or the super-user is permitted either to get or to set the resource limits of a process. Only the super-user can increase the hard limit. OPTIONS
The following options are supported: -k On output, show file sizes in kilobytes (1024 bytes) rather than in 512-byte blocks. -m On output, show file and memory sizes in megabytes (1024*1024 bytes). The remainder of the options are used to change specified resource limits. They each accept an argument of the form: soft,hard where soft specifies the soft (current) limit and hard specifies the hard (maximum) limit. If the hard limit is not specified, the comma may be omitted. If the soft limit is an empty string, only the hard limit is set. Each limit is either the literal string unlimited, or a number, with an optional scaling factor, as follows: nk n kilobytes nm n megabytes (minutes for CPU time) nh n hours (for CPU time only) mm:ss minutes and seconds (for CPU time only) The soft limit cannot exceed the hard limit. -c soft,hard Set core file size limits (default unit is 512-byte blocks). -d soft,hard Set data segment (heap) size limits (default unit is kilobytes). -f soft,hard Set file size limits (default unit is 512-byte blocks). -n soft,hard Set file descriptor limits (no default unit). -s soft,hard Set stack segment size limits (default unit is kilobytes). -t soft,hard Set CPU time limits (default unit is seconds). -v soft,hard Set virtual memory size limits (default unit is kilobytes). OPERANDS
The following operands are supported. pid Process ID list. EXIT STATUS
plimit returns the exit value zero on success, non-zero on failure (such as no such process, permission denied, or invalid option). FILES
