              Who Talks TCP? -- Survey of 22 February 1983

The list of hosts was taken from the NIC hostname table of 18-Feb-83.
The tests were run on 22-Feb-83 from 8 am to ~8:05 pm PST from
    ISI-VAXA.ARPA.
Dead, refused, and unreachable hosts were retried from 10 am 23-Feb-83
     to ~6:40 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)
