I did not get any takers on the associate list, so I'll try the main list.
I am a little confused about port numbers. I understand what they are for,
but I do not quite understand how to track down why a host would be
listening to a particular port and how to find out who asked for the port to
be defined and what the port is being used for. For example netstat -a from
my machine shows in part the following
Proto Local Address State
TCP name:1059 LISTENING
TCP name:1060 LISTENING
TCP name:1877 LISTENING
of course there are many others. I understand that to track these down I go
to ftp://ftp.isi.edu/in-notes/iana/assignments/ and download the file named
port-numbers. I then look for each port shown above and this tells me the
name of the port and who registered it. For example, port 1059 is named
nimreg. It was registered by Robert Gordon at austin.ibm.com. Short of
asking Robert, how do I find out what nimreg is and why a Windows 98 SE host
would be listening on such a port.
Also I have seen people on the list ask what port Napster uses for example.
People respond back with a number, yet I see no listing for Napster on the
list I downloaded.
What am I missing here?
