By uncommenting this line "WOPort=55555"in the Properties file it now
always points to that port. That's great.
I wanted to have another number so I changed it to 362436 and saved,
rebuilt, etc. The app won't run, it always exits with status 1.
Hah! That's a funny one. Internet Protocol port numbers are stored in
an unsigned 16 bit quantity. So, please, try to keep your port numbers
below 65535 (or thereabouts). Also, ports below 1024 are restricted
use/privileged ports. So, please try to keep your ports above 1024.
Finally, many applications/daemon processes use various ports for their
own (probably nefarious) reasons. So, try to avoid using any of those
(e.g. telnet's port, ftp's port, http's port, etc).
I guess the upshot is that you can't just use any port you may feel
like. The port you choose must be somewhat carefully considered and
researched.
