yes, this is OK

I get: tcp  0  0 0.0.0.0:5432  0.0.0.0:*  LISTEN

I'll have to look up what these mean and how to do them.I'm still pretty ignorant. :-)

I did!

I got error no such command. So installed telnet, and now get:"telnet: unable to connect to remote host: Network is
unreachable."
It is now quite apparent that my problem is not with PgAccess, but with     my 
network setup. I'll work on this. I see that I have lots more reading     to 
do!Many thanks to you all for the help. I would never have thought of these things myself.

Getting off-topic, but if I assume correctly that you are running
linux, may I recommend a book called "Running Linux", but Matt Welsh,
et.al.?  It will give you a lot of guidance as you sort these details
out...

In the end, you should be able to see this kind of result locally:

% ping localhost
PING localhost (127.0.0.1) from 127.0.0.1 : 56 data bytes
64 bytes from 127.0.0.1: icmp_seq=0 ttl=255 time=0.1 ms
64 bytes from 127.0.0.1: icmp_seq=1 ttl=255 time=0.0 ms
64 bytes from 127.0.0.1: icmp_seq=2 ttl=255 time=0.0
ms                         
...
