| − | #
| |
| − | #Each line describes a limit for a user in the form:
| |
| − | #
| |
| − | #<domain> <type> <item> <value>
| |
| − | #
| |
| − | #Where:
| |
| − | #<domain> can be:
| |
| − | # - a user name
| |
| − | # - a group name, with @group syntax
| |
| − | # - the wildcard *, for default entry
| |
| − | # - the wildcard %, can be also used with %group syntax,
| |
| − | # for maxlogin limit
| |
| − | # - NOTE: group and wildcard limits are not applied to root.
| |
| − | # To apply a limit to the root user, <domain> must be
| |
| − | # the literal username root.
| |
| − | #
| |
| − | #<type> can have the two values:
| |
| − | # - "soft" for enforcing the soft limits
| |
| − | # - "hard" for enforcing hard limits
| |
| − | #
| |
| − | #<item> can be one of the following:
| |
| − | # - core - limits the core file size (KB)
| |
| − | # - data - max data size (KB)
| |
| − | # - fsize - maximum filesize (KB)
| |
| − | # - memlock - max locked-in-memory address space (KB)
| |
| − | # - nofile - max number of open file descriptors
| |
| − | # - rss - max resident set size (KB)
| |
| − | # - stack - max stack size (KB)
| |
| − | # - cpu - max CPU time (MIN)
| |
| − | # - nproc - max number of processes
| |
| − | # - as - address space limit (KB)
| |
| − | # - maxlogins - max number of logins for this user
| |
| − | # - maxsyslogins - max number of logins on the system
| |
| − | # - priority - the priority to run user process with
| |
| − | # - locks - max number of file locks the user can hold
| |
| − | # - sigpending - max number of pending signals
| |
| − | # - msgqueue - max memory used by POSIX message queues (bytes)
| |
| − | # - nice - max nice priority allowed to raise to values: [-20, 19]
| |
| − | # - rtprio - max realtime priority
| |
| − | # - chroot - change root to directory (Debian-specific)
