From afeb6834597dba7c2546f36f5de61f218fbd5b4b Mon Sep 17 00:00:00 2001 From: Eric Andersen Date: Sun, 4 Jun 2000 05:21:49 +0000 Subject: "nc" exits silently on errors. This patch makes it print something before exit(). Note that calling perror() after gethostbyname() will most likely return "No such file or directory" which is quite confusing, so I decided to use fatalError instead.
