"man netstat"?

Address formats are in two forms: host.port, or network.port if the
host portion of a socket address is zero. When known, the host and
network addresses are displayed symbolically by using gethostbyname()

Is the mystery item under the "Local Address"
heading?

Which part of "hostname.59624" do you not
understand? "hostname" is the host name,
"59624" is the port number. (Just as
"fullyqualified hostname" is a host name, and
"5001" is a port number.)

Perhaps it would help if you supplied some
actual output from a "netstat -an" command on
each system. Perhaps
netstat -an | grep '.5001 '

Also, "my other system" is not a useful
description of either system. With what are
you working here?

Are you expecting some application to be
listening on port 5001?

What is your actual queation? What problem
are you trying to solve?

There is another column at the end of the netstat output. It is the state output and it should tell you what the socket is doing.

Please post something like this

Run netstat on hostA

tcp 0 0 hostA.59624 hostB.dom.com.5001 STATUS

Run netstat on hostB

tcp 0 0 hostB.???? hostA.???? STATUS
