                           Who Talks TCP?

The list of hosts was taken from the NIC hostname table of 31-Dec-82.
The tests were run on 11-Jan-83 from ~12:01 pm to ~8:45 pm PST.
Dead, refused, and unreachable hosts were retried 12-Jan-83 from ~8:00 am
     to ~4:30 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)
