PAM_SETQUOTA(8) Linux-PAM Manual PAM_SETQUOTA(8)
pam_setquota - PAM module to set or modify disk quotas on session
start
pam_setquota.so [fs=/home] [overwrite=0] [debug=0]
[startuid=1000] [enduid=0] [bsoftlimit=19000]
[bhardlimit=20000] [isoftlimit=3000]
[ihardlimit=4000]
pam_setquota is a PAM module to set or modify a disk quota at
session start
This makes quotas usable with central user databases, such as
MySQL or LDAP.
fs=/home
The device file or mountpoint the policy applies to. Defaults
to the filesystem containing the users home directory.
overwrite=0
Overwrite an existing quota. Note: Enabling this will remove
the ability for the admin to manually configure different
quotas for users for a filesystem with edquota(8). (Defaults
to 0)
debug=0
Enable debugging. A value of 1 outputs the old and new quota
on a device. A value of 2 also prints out the matched and
found filesystems should fs be unset. (Defaults to 0)
startuid=1000
Describe the start of the UID range the policy is applied to.
(Defaults to UID_MIN from login.defs or the uidmin value
defined at compile-time if UID_MIN is undefined.)
enduid=0
Describe the end of the UID range the policy is applied to.
Setting enduid=0 results in an open-ended UID range (i.e. all
uids greater than startuid are included). (Defaults to 0)
bsoftlimit=19000
Soft limit for disk quota blocks, as defined by quotactl(2).
Note: bsoftlimit and bhardlimit must be set at the same time!
bhardlimit=20000
Hard limit for disk quota blocks, as defined by quotactl(2).
Note: bsoftlimit and bhardlimit must be set at the same time!
isoftlimit=3000
Soft limit for inodes, as defined by
quotactl(2). Note: isoftlimit and ihardlimit must be set at
the same time!
ihardlimit=4000
Hard limit for inodes, as defined by
quotactl(2). Note: isoftlimit and ihardlimit must be set at
the same time!
Only the session module type is provided.
PAM_SUCCESS
The quota was set successfully.
PAM_IGNORE
No action was taken because either the UID of the user was
outside of the specified range, a quota already existed and
overwrite=1 was not configured or no limits were configured
at all.
PAM_USER_UNKNOWN
The user was not found.
PAM_PERM_DENIED
/proc/mounts could not be opened.
The filesystem or device specified was not found.
The limits for the user could not be retrieved. See syslog
for more information.
The limits for the user could not be set. See syslog for more
information.
Either isoftlimit/ihardlimit or bsoftlimit/bhardlimit were
not set at the same time.
A single invocation of `pam_setquota` applies a specific policy
to a UID range. Applying different policies to specific UID
ranges is done by invoking pam_setquota more than once. The last
matching entry defines the resulting quota.
