I've reproduced the problem with a very bare server
script, the following 4 lines:
from twisted.spread import pb
from twisted.internet import reactor
I have two machines, shuttle-1 and shuttle-2. I have
no problem on shuttle-1, I get the "Connection
refused" error on shuttle-2.
Before starting the server, "telnet localhost 8789",
"telnet shuttle-1 8789" and "telnet shuttle-2 8789"
all fail with the following messge, as expected, from
Trying <ip add>...
telnet: connect to address <ip add>: Connection
After starting the server on both machines,
~ telnet localhost 8789
works on both machines, and
~ telnet shuttle-1 8789
works from shuttle-2, but
~ telnet shuttle-2 8789
from shuttle-1 fails with the Connection refused
In addition, after starting the server, the following
line is added to the output of "netstat -ntlp" on both
tcp 0 0 0.0.0.0:8789 0.0.0.0:*
modulo the PID.
Is there somewhere else to look?
Also, perhaps someone can suggest a terse introduction
to Linux networking.
