PAM_TIMESTAMP_CHECK(8) Linux-PAM Manual PAM_TIMESTAMP_CHECK(8)

NAME

pam_timestamp_check – Check to see if the default timestamp is valid

SYNOPSIS

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’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 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 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
auth sufficient pam_timestamp.so verbose
auth required pam_unix.so

session required pam_unix.so
session optional pam_timestamp.so

FILES
/var/run/sudo/…
timestamp files and directories
