              Who Talks TCP? -- Survey of 8 February 1983

The list of hosts was taken from the NIC hostname table of 3-Feb-83.
The tests were run on 8-Feb-83 from 10 am to ~5:10 pm PST, and on
    9-Feb-83 from 1 am to ~5:15 am PST from ISI-VAXA.ARPA
Dead, refused, and unreachable hosts were retried 9-Feb-83 from ~8 am
     to ~4:40 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)
