badly signed NOP response from dcc1.dcc-servers.net (216.240.97.63,6277)

Hi, I'm having trouble with a fresh install.  I've read a number of threads
in the archive with no luck.  This will be run on a server that is not
behind a firewall, but it is firewalled itself.  There is no outbound
blocking, and I have it set to accept UDP and TCP 6277.  I'm trying to get
anon working before I set up an ID and all that, is that a mistake?

[root@smtp dcc]# cdcc "debug on; id 1; load -" < map.txt
