Who Talks TCP?
The list of hosts was taken from the NIC hostname table of 20-Dec-82.
The tests were run on 4-Jan-83 from ~12:01 pm to ~1:10 am PST Jan. 5.
Dead, refused, and unreachable hosts were retried 5-Jan-83 from ~8:00 am
to ~4:15 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)
