Name
pam_timestamp_check - Check to see if the default timestamp is validSynopsis
pam_timestamp_check [-k] [-d] [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\*(Aqs -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 the user authenticates as herself. 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.
Examples
