	      Who Talks TCP? -- Survey of 15 February 1983

The list of hosts was taken from the NIC hostname table of 3-Feb-83.
The tests were run on 15-Feb-83 from 8 am to ~12:30 pm PST, and on
    16-Feb-83 from 10 am to ~11:10 am PST from ISI-VAXA.ARPA
Dead, refused, and unreachable hosts were retried from 10 pm 16-Feb-83
     to ~6:40 am 17-Feb-83.

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)
