I am currently studying at UCD, Dublin, Ireland.
By every international student, a lot of time is spent organizing things: Courses, Accomodation and the like. That's tradition.
Also, everyone who needs the internet needs to organize his access to it from the university's network, too.

Here at UCD they use a Proxy server (a computer that channels all internet traffic from registered users). They have a IT staff that help all students configuring their browser (IE mostly :-( ) so that they can surf.
For me, that's not enough. I have a whole bunch of other applications than browsing that I need to work with internet. There is Skype for internet telephony. There is file transfer with the webserver that I rent for hosting this (and other) homepages. And there is Subversion, a code control system, that helps to organize several peopls's work on the same program files.

I really need those. And the IT guys are really not that helpful, especially for people with Mac computers. The problem is that you never know what the Proxy server allows and what it just won't let through unless you've configured it yourself. They could really give out info about that, but maybe there are just not many people like me here...

I still have problems, especially with subversion, which works with some servers, but not with others...
Anyway, here are some good hints for all people that also need to get along with their proxies:

  • For Mac users: use Authoxy. It's a tool that will intercept all requests and forward them to the Proxy. I got Skype working that way.
  • For FTP: There might be just no way you can get a decent FTP program to work properly behind some proxies. I installed lftp and got it working somehow, but it wouldn't let me delete. What the... ? So I remembered a hint someone gave me years ago and surfed to www2ftp.de. These guys let you do File Transfer over HTTP with the browser. And it works great. You can even upload a whole Archive with stuff and the tool will put every file at the right place!
  • For subversion, the place to specify a proxy is ˜/.subversion/servers - but I do have my issues with it, still.
  • And again sthg for Mac-Users: Darwinports (slow, but worthwile) will need to know the Proxy, too. Set the system variables "http_proxy" and "FTP_PROXY". For example, you could add these lines to your .profile - file (replacing the UCD proxy with yours):
        export http_proxy=http://proxy.ucd.ie:8484
        export FTP_PROXY=http://proxy.ucd.ie:8484

You will have to restart your Terminal session afterwards, of course.

I'm using a mac in ucd as well and the proxy is driving me nuts. I tried installing authoxy like you said but it didn't seem to make any difference. Basically what I'm trying to get running is Adium and Mail (it can only access my ucdconnect account, no external ones). I don't know if you've any experience in this regard but you seem to know a lot more than I do so I guess it's worth a shot. Thanks!

Hi Niall

I didn't use those programs.
Just trying to cough up some things:
-Did you start Authoxy (installing is not enough)
-Did you set up the environment in System Settings -> Network? You can specify http(s) proxies there
-Generally, I think they only care about HTTP stuff (basically making surfing possible) but not much more. Mail and Instant Messaging may use other protocols... The best thing is always ro look for a web-based substitution. For example, maybe your email-provider has a web-frontend. For Instant Messaging, you might want to try http://wwwl.meebo.com/.
Don't know if that was helpful, but anyway, have Fun at UCD,

Here at Newcastle uni they seem to be more friendly towards Linux. First thing I saw once I was on their wifi and tried to connect to a website was this: http://docking.ncl.ac.uk/proxy/linux/ I found it pretty helpful.
