                   Who Talks TCP?

The list of hosts was taken from the NIC hostname table of 2-Dec-82.
The tests were run on 7-Dec-82 from ~12:01 am to ~2:15 am PST and from
     ~12:30 pm to ~7:00 pm PST.
Dead, refused, and unreachable hosts were retried 8-Dec-82 from ~3:15 pm
     to ~4:30 pm PST.

Claims are taken from the NIC host table:

= tcp (no particular services mentioned)
= tcp/telnet
= tcp/ftp
= tcp/smtp

Results for each service:

lank (not accepted)
efused
nreachable
ead
ccepted
ccepted+ (FTP allowed user anonymous, password guest)
