			   Who Talks TCP?

The list of hosts was taken from the NIC hostname table of 2-Dec-82.
The tests were run on 28-Dec-82 from ~12:01 pm to ~8:10 pm PST.
Dead, refused, and unreachable hosts were retried 29-Dec-82 from ~8:00 am
     to ~7:40 pm PST.

Claims are taken from the NIC host table:
	T = tcp (no particular services mentioned)
	t = tcp/telnet
	f = tcp/ftp
	s = tcp/smtp

Results for each service:
	blank (not accepted)
	refused
	unreachable
	dead
	accepted
	accepted+ (FTP allowed user anonymous, password guest)
