	      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)
