NAME

pam_timestamp_check - Check to see if the default timestamp is valid

CONTENTS

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 sudos -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/...
