pam_timestamp_check(8) -- Linux man page

 

NAME

pam_timestamp_check - check or clear authentication timestamps  

SYNOPSIS

pam_timestamp_check [[-d]|[-k]] [target_user]

 

DESCRIPTION

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
The default behavior of pam_timestamp_check checks or removes timestamps generated by pam_timestamp when the user authenticates as herself. When the user authenticates as a different user, the name of the timestamp file changes to accomodate this.

 

DIAGNOSTICS

When checking if a timestamp is valid, pam_timestamp_check returns an exit code of 0 for success and > 0 on error:

2: binary is not setuid-root
3: invalid invocation
4: user unknown
5: permissions error
6: invalid controlling tty
7: other error
