Ktell

The ktell utility is a highly efficient user-level daemon that effectively monitors the expiration time of Kerberos ticket granting tickets in a seamless manner. One of the standout features of the ktell utility is its ability to issue a timely warning to the user's least idle terminal whenever a certain pre-determined time is reached before the ticket expires.

In the case of a Linux system that has the 'pidof' utility included, adding the ktell utility is a quick and hassle-free process. By simply adding a check to your startup profile, ktell can be launched safely and reliably. For instance, on the bash(1) shell, using the following code snippet:

if [ -x /usr/bin/ktell ] && [ "`/sbin/pidof /usr/bin/ktell`" = "" ]; then
/usr/bin/ktell
fi

You can effectively ensure that ktell starts running efficiently and smoothly without any hiccups.

Furthermore, the ktell utility also comes with a customizable checking interval and the time before expiry in which to send a message on the command line, making it even more flexible and adaptable. Overall, the ktell utility is a super-efficient tool that any user would love to have in their arsenal of software utilities.
