Remote server firewall issues

[johnnyt]

Hey @AllenOtis or @jgfoster -

I am trying to get a remote server up and running through a firewall. I added the -p50379:50379 option to the netldis on both the stone and remote machine, but it looks like the pgsvrmain is still trying to connect to a random port.

1. Is that correct (that the pgsvrmain is trying to connect to a random port)?

and if so

2. Is there any way to specify a specific port for firewall purposes?

BTW - Here are some of the logs being generated:

The netldi(s) need to each be started with the
-p lowPort:highPort
argument.
See output of
startnetldi -h
for details. Also note the -P option which specifies
the listening port for the netldi .

For the stone process, note the STN_WELL_KNOWN_PORT_NUMBER
item in the stone config file , to specify the listening port for the stone
process.

The port range needs to be more than one port, to allow time for
connections to be completed to mulitlple forked processes. I would
allow at least 100 ports . Otherwise presumably there is a bug in 3.1.0.2
server code that we would have to evaluate . I would like to see all
the relevant log files if you can't get it to work .
