# skeyaudit(1)

warn users if their S/Key will soon expire

## NAME

**skeyaudit** – warn users if their S/Key will soon expire

## SYNOPSIS

**skeyaudit** \[**-ai**\] \[**-l** *limit*\]

## DESCRIPTION

**skeyaudit** searches through the files in */etc/skey* for users whose S/Key sequence number is less than *limit*, and mails them a reminder to run [skeyinit(1)](/skeyinit/1.md) soon.

The options are as follows:

- **-a**

  Check all keys in */etc/skey*. This option is only available to the superuser and is useful to run regularly via [cron(8)](/cron/8.md).

- **-i**

  Interactive mode. Don't send mail, just print to the standard output.

- **-l** *limit*

  The limit used to determine whether or not a user should be notified. The default is to notify if there are fewer than 12 keys left.

## FILES

- */etc/skey*

  directory containing user entries for S/Key
