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/...
