[erlang-questions] how to connect erlang nodes through an uncontrolled firewall
Tue May 10 16:24:13 CEST 2011
I'd like to connect a couple of erlang nodes together, one "here", one
on a remote machine. There are two firewalls in the way: one on the
remote machine, one local.
The remote firewall I can ask for ports to be opened. I've read that
4369 for epmd and one other port are required (the second can be
assigned at runtime using sth like
erl -name qweasd -kernel inet_dist_listen_min 9001
inet_dist_listen_max 9001 
The local firewall is fixed, in the sense that I don't think I can ask
for ports to be opened and so on (I'm in a shared office building with
provided internet access).
Is there anything I can do at this end to open a connection? I can ssh
out the the remote machine. Can I have the nodes connect over ssh?
With thanks and best wishes
