idlookup(1) idlookup(1)
NAME
idlookup - identify the user of a particular TCP connection
SYNOPSIS
idlookup {host-or-ip-number} {local-port} {foreign-port}
DESCRIPTION
Idlookup can be used to identify the user at the remote end of a TCP
connection, assuming the host at the other end is running an
Identification Server.
host-or-ip-number is the name of the host at the other end of the
connection, or its IP address.
local-port and foreign-port are the port numbers, or service names of
the ports at the two ends of the connection.
WARNING
Note that the references to local-port and foreign-port follow the
terminology in RFC931, and are from the point of view of the server
rather than the user.
