-[BarnOwl](http://barnowl.mit.edu/) is a command-line Zephyr client that supports advanced filtering and customisation. It is probably the most commonly used client, but requires some effort to get started. To use BarnOwl effectively, you should connect to an [Athena dialup](http://web.mit.edu/dialup/www/ssh.html) and run BarnOwl along with a program to renew your Kerberos tickets. The Athena command `athrun sipb pag-screen` will set up ticket renewal, and `athrun barnowl` after that will run BarnOwl itself.
