John Hi, I'd like to join the APRS network via my T-Mobile cell phone
John which offers unlimited "internet access". I put Internet in
John quotes because only certain ports are allowed out. Port 80 is
John one of those ports.

Jack This is probably because they do some magical stuff between your
Jack phone and their Internet connection. I expect the software they
Jack run does everything from shrink images to blocking unusual data
Jack like yours.

John As far as I can tell all traffic is allowed on the open
John ports. I've set up an SSH server on one of the open ports and I
John can ssh over the link. It works fairly well.

Well that's good news. If ssh works, then APRS will almost definitely
work.

John If the APRS software was socks-aware, I could use ssh (which has
John a built-in socks server) to allow APRS to reach the Internet
John through my home connection. I don't think WinAPRS supports
John socks?

I'm not familiar with WinAPRS. I am one of the developers on the
xastir team, though, and xastir can work with socks.

John Is there anyway that I can report and receive APRS data via the
John Internet using Port 80 instead of the standard 10xxx port (I
John forget the exact number)?

Jack If your home computer is always on the Internet and doesn't
Jack currently have a web server running on it, there are ways to
Jack redirect traffic such that any connection to your home
Jack computer's port 80 is redirected to another server's port
Jack whatever, but I would not be surprised if it didn't work due to
Jack the aforementioned magic.

John I thought about this. It's a little clumsy, but still doable. Is
John there a way to change the hostname that WinAPRS connects to so I
John can put in my home IP?

Again, I'm unfamiliar with WinAPRS, but it does seem to be a
reasonable thing to add -- and xastir lets you use any port, not just
10151 or whatever the default is these days. xastir will run on
Windows if the Cygwin environment is installed -- email me if you'd
be interested in giving that a try. I used xastir on my wife's
Windows XP laptop for a week-long jaunt around the American Southwest
recently and it worked fine.

John Thanks, John

Jack.
