Why port blocking is bad

[torkell]

Because this is what you get if Java gets given port 3130 by Windows:



And in Eclipse I was greated by the wonderful message of:

FATAL ERROR in native method: No transports initialized
err:: No such file or directory
Error [2] in connect() call!
Socket transport failed to init.
Transport dt_socket failed to initialize, rc = -1.

Thank you, Norton.

Absolutely no idea. You actually have to explicitly allow them if you're running IIS, or strange stuff happens. Found that one the hard way - had IIS locked down to local private subnet and trusted IPs on http and ftp, and blocked everything. Then wondered why if I tried to stop/restart/admin IIS it fell over and locked. I also had to kill outbound e-mail virus scanning, as that was eating the encrypted connections OE needed to talk to the uni servers.
