Who Talks TCP?

The list of hosts was taken from the NIC hostname table of 31-Dec-82. The tests were run on 18-Jan-83 from ˜12:01 pm to ˜10:10 pm PST. Dead, refused, and unreachable hosts were retried 19-Jan-83 from ˜7:00 pm to ˜1:30 am PST, and 20-Jan-83 from ˜10:50 am to 1:00 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)
