From 4f5e5e878e84342aacec3f7fba9ff9162a15e028 Mon Sep 17 00:00:00 2001
From: brian <brian@openbsd.org>
Date: Wed, 29 Mar 2000 09:32:26 +0000
Subject: [PATCH] Allow the use of hostnames instead of (and as well as) IP
 numbers in all commands. If people use hostnames and have dodgy resolvers or
 try to resolve the hostname before the link is up, they get what they
 deserve....
