University Network & Madsonic

[KicknGuitar]

I recently moved to a University campus but left my subsonic (Madsonic mod) server running at my old place. While I can access the server from most networks, my new university network blocks the way Subsonic connects to the device. It returns a timeout message in the browser.

Is there anything to do on my own before going to the campus' IT? What should I ask them is being blocked or how it's being blocked?

Thanks for the help.

I can see one of two things blocking it. 1) a non-standard port (4040). 2) a dyn-dns home address.

My normal home server goes to <something>.homedns.org - my work decided to block that: it simply refuses to allow even the IP name resolution. The <myserver>.subsonic.org address might help, but I found other issues with that redirect that broke a few things in my app (esp on Firefox, but that was almost a year ago so maybe things changed).

I got around it by adding a cname entry to be able to connect to home from a subdomain of a domain I already own from my hosting ISP, but that's not an option available to everybody.

The only workaround for 4040, a port number blocked by a lot of public wifi sites as well (I can't connect to that in many restaurants and shopping malls), is to move it to a different port. For a while I had a proxy rigged up in nginx, but that box got retired and the new box has apache on it (for OwnCloud) so I need to figure out mod_proxy rewrite rules.

First off, simply try moving the port number up above the more common 4-digit port numbers - try for instance 10443 or 20002, as 2 simple examples. Many universities perform blocking of certain well-known ports that are often associated with web proxies or 3rd party web services, etc. So avoid 4040, 8080 and the like - instead, try 20002 and I'll bet that gets ya done....
