модуль PAM для ограничения ресурсов (PAM module to limit resources)
Имя (Name)
pam_limits - PAM module to limit resources
Синопсис (Synopsis)
pam_limits.so
[conf=/path/to/limits.conf] [debug] [set_all]
[utmp_early] [noaudit]
Описание (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. Then individual *.conf files from the
/etc/security/limits.d/ directory are read. The files are parsed
one after another in the order of "C" locale. 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 a module option then the files in
the above directory 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.
Параметры (Options)
conf=
/path/to/limits.conf
Indicate an alternative limits.conf style configuration file
to override the default.
debug
Print debug information.
set_all
Set the limits for which no value is specified in the
configuration file to the one from the process with the PID
1.
utmp_early
Some broken applications actually allocate a utmp entry for
the user before the user is admitted to the system. If some
of the services you are configuring PAM for do this, you can
selectively use this module argument to compensate for this
behavior and at the same time maintain system-wide
consistency with a single limits.conf file.
noaudit
Do not report exceeded maximum logins count to the audit
subsystem.

Примеры (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.
