pam_timestamp_check8
Check to see if the default timestamp is valid
Usage
pam_timestamp_check [-k]
[-d]
[target_user]
Overview
With no arguments pam_timestamp_check will check to see if the default timestamp is valid, or optionally remove it.
Options
-
-k -
Instead of checking the validity of a timestamp, remove it. This is analogous to sudo's -k option.
-
-d -
Instead of returning validity using an exit status, loop indefinitely, polling regularly and printing the status on standard output.
target_user
By default pam_timestamp_check checks or removes timestamps generated by pam_timestamp when users authenticate as themselves. When the user authenticates as a different user, the name of the timestamp file changes to accommodate this. target_user allows one to specify this user name.
Return values
0
The timestamp is valid.
2
The binary is not setuid root.
3
Invalid invocation.
4
User is unknown.
5
Permissions error.
6
Invalid controlling tty.
7
Timestamp is not valid.
Notes
Users can get confused when they are not always asked for passwords when running a given program. Some users reflexively begin typing information before noticing that it is not being asked for.
