NAME¶
pam_limits - PAM module to limit resources
SYNOPSIS¶
pam_limits.so [conf=/path/to/limits.conf] [debug] [set_all] [utmp_early] [noaudit]
DESCRIPTION¶
The pam_limits PAM module sets limits on the system resources that can be obtained in a user-session. Users of uid=0 are affected by this limits, too.
By default limits are taken from the /etc/security/limits.conf config file or, if that one is not present, the file /usr/etc/security/limits.conf. Then individual *.conf files from the /etc/security/limits.d/ and /usr/etc/security/limits.d directories are read. If /etc/security/limits.d/@filename@.conf exists, then /usr/etc/security/limits.d/@filename@.conf will not be used. All limits.d/*.conf files are sorted by their @filename@.conf in lexicographic order regardless of which of the directories they reside in. The effect of the individual files is the same as if all the files were concatenated together in the order of parsing. If a config file is explicitly specified with the config option the files in the above directories are not parsed.
The module must not be called by a multithreaded application.
If Linux PAM is compiled with audit support the module will report when it denies access based on limit of maximum number of concurrent login sessions.

EXAMPLES¶
For the services you need resources limits (login for example) put a the following line in /etc/pam.d/login as the last line for that service (usually after the pam_unix session line):
#%PAM-1.0 # # Resource limits imposed on login sessions via pam_limits # session required pam_limits.so
Replace "login" for each service you are using this module.
