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)
