Information about Port 1

  • Port 1 is a allocated to the TCP Port Service Multiplexer (TCPMUX) protocol by IANA, however this a little-used protocol and was deprecated in 2016 for technical reasons and a lack of use. The purpose of TCPMUX was that a host could connect to a server that supports is, send the name of the service required, a carriage return and line feed characters and the server will response with a ‘+’ or ‘-‘ character, an optional message and a carriage return line feed. If the server returns a ‘+’ reply, this means the protocol or service that was requested has been started, otherwise the connection will be closed. A client can send a “HELP” command to the server, and the server will return a list of supported services.

  • One of the major problems with this protocol is that it allows an attacker to enumerate the services running on the machine through a single port (unlike a port scan which is noisy). Furthermore, this service allows any service to be accessed through port 1, bypassing firewall rules. For that reason, it should not be used.
