I tried your suggestion, and I can connect to localhost at port 5432 as you
show below, and I can log in to the other machine and telnet to birch, port
5432, over the network. In both cases it connects, and then disconnects as
soon as I type something and send it; I don't get an error message as you show
below, just the Connection closed by foreign host message. So, I tried my
simple jdbc example, and I'm still getting the Connection refused error. Just
for grins, I went back to birch and tried running the same code, in which the
URL looks like "jdbc:postgresql://birch/coffeebreak". That works, even with
the hostname rather than "localhost".
I can't imagine there's anything out of the ordinary with these two machines.
They're both vanilla RedHat systems, plugged into the same ethernet hub, static
It seemed like a good idea. Thanks. I'm still stumped.
