|
* An interesting story. The name attached to this port in
the IANA list, Earl Killian, says he shouldn't be. He says "I don't know
what 81 is, or whether it is still in use." Since Mr. Killian doesn't
know what HOSTS2 is/was, and with Postel gone, I wonder if there's anyone left
in the world who knows what 81 was/is for and who actually requested it.

Utility and its use of tcp and udp port # 82. XFER employs a proprietary
protocol which has not been disclosed.
