12
14 pam_setquota is a PAM module to set or modify a disk quota at session
15 start
16 This makes quotas usable with central user databases, such as MySQL or
18 LDAP.
19
21 fs=/home
22 The device file or mountpoint the policy applies to. Defaults to
23 the filesystem containing the users home directory.
24 overwrite=0
26 Overwrite an existing quota. Note: Enabling this will remove the
27 ability for the admin to manually configure different quotas for
28 users for a filesystem with edquota(8). (Defaults to 0)
29 debug=0
31 Enable debugging. A value of 1 outputs the old and new quota on a
32 device. A value of 2 also prints out the matched and found
33 filesystems should fs be unset. (Defaults to 0)
34 startuid=1000
36 Describe the start of the UID range the policy is applied to.
37 (Defaults to UID_MIN from login.defs or the uidmin value defined at
38 compile-time if UID_MIN is undefined.)
39 enduid=0
41 Describe the end of the UID range the policy is applied to. Setting
42 enduid=0 results in an open-ended UID range (i.e. all uids greater
43 than startuid are included). (Defaults to 0)
44 bsoftlimit=19000
46 Soft limit for disk quota blocks, as defined by quotactl(2). Note:
47 bsoftlimit and bhardlimit must be set at the same time!
48 bhardlimit=20000
50 Hard limit for disk quota blocks, as defined by quotactl(2). Note:
51 bsoftlimit and bhardlimit must be set at the same time!
52 isoftlimit=3000
54 Soft limit for inodes, as defined by
55 quotactl(2). Note: isoftlimit and ihardlimit must be set at the
56 same time!
57 ihardlimit=4000
59 Hard limit for inodes, as defined by
60 quotactl(2). Note: isoftlimit and ihardlimit must be set at the
61 same time!
62
64 Only the session module type is provided.
65
67 PAM_SUCCESS
68 The quota was set successfully.
69 PAM_IGNORE
71 No action was taken because either the UID of the user was outside
72 of the specified range, a quota already existed and overwrite=1 was
73 not configured or no limits were configured at all.
74 PAM_USER_UNKNOWN
76 The user was not found.
77 PAM_PERM_DENIED
79 /proc/mounts could not be opened.
80 The filesystem or device specified was not found.
82 The limits for the user could not be retrieved. See syslog for more
84 information.
85 The limits for the user could not be set. See syslog for more
87 information.
88 Either isoftlimit/ihardlimit or bsoftlimit/bhardlimit were not set
90 at the same time.
91
93 A single invocation of `pam_setquota` applies a specific policy to a
94 UID range. Applying different policies to specific UID ranges is done
95 by invoking pam_setquota more than once. The last matching entry
96 defines the resulting quota.
