[ome-users] OMERO.server and external connections

Hi Sean. I'll see if I can suggest anything that you haven't tried yet
(which is quite a lot!), but log files from the client and from the
server would be helpful.

So there are two hosts involved: "local" and "remote". A client
running on "local" can also communicate with a server on "local", right?

Just to check the obvious: is the client's host ("remote") also in the
192.168 subnet?

4444 is great. But do you have 1098 and 1099?
$netstat -nav | grep 1099
tcp        0      0 0.0.0.0:1099            0.0.0.0:*               LISTEN   
 
If not, it may be that the server didn't start up properly, which
would be in the log.

There are no requirements on the database for client access. It's only
important that you can access the server on "remote" from "local" as
you specify it within insight or importer, whethr via IP or
hostname. Can you ssh to that box? Or ping it?

Not much help yet, but we'll get there.
