[GTALUG] War Story: debugging remote port access

[John Sellens]

Thanks for the port war story.

I've learned that something like

    netstat -na | grep -w LISTEN

often helps me discover/confirm port problems.

And having a telnet client (or nc) on another machine, often provides
much more specific answers than a web browser or an application client
(which often say "something went wrong" with no further details).

Cheers

John
