Doesn't network messenging have to also have a listening port on both sides as well?
Otherwise, how could they communicate?

It may be that the remote (or even the local) server doesn't have the talkd running on it.

Name
       talkd - inter-terminal communications server

Syntax
       /etc/talkd

Description
       The  program  is  the  server  for the program.	The server provides a rendezvous method for the requesting (possibly remote) and the local
       responding

       The server is invoked by when it receives a packet on the port indicated in the talk service specification.

Restrictions
       The server does not strictly follow network byte order in its packet format and may have difficulty in talking with implementations  of	on
       other architectures that do not take this into account.

       The  version  of  released  with ULTRIX V3.0 uses a protocol that is incompatible with the protocol used in earlier versions. Starting with
       ULTRIX V3.0, the program communicates with other machines running ULTRIX, V3.0 (and later), and machines running 4.3  BSD  or  versions	of
       UNIX based on 4.3 BSD.

       The command is not 8-bit clean. Typing in DEC Multinational Characters (DECMCS) causes the characters to echo as a sequence of a carets (^)
       followed by the character represented with its high bit cleared. This limitation makes unusable if you want to communicate using a language
       which has DECMCS characters in its alphabet.
