overcoming firewall at uni

  1. Hi all.

    ive noticed that alot of you know more than just motorcycles so i will field my question here if you all dont mind :)

    i cant access my outlook and other net based programs needed to conduct my work while on campus.

    i know that to access certain pages i can run it off other web sites but not sure what i can do regarding my programs.

    any suggestions?

  2. You could find out if your Uni provides proxy services for the protocols you want to use. But with email you'll probably be stuck with using webmail until you can download the mail from home.

    thier are also a number of web interfaces to Instant messanging programs like MSN so have a search for those. Without knowing what other applications you want to use theres not much more i can suggest.
  3. being the leetest haxxer in the world, I will evade the answer to your question!

    at school tho.. we used to google p0rn, then hit "cache" to avoid the filter.
    Oh such golden times.
  4. thanks matt..

    hope your doing well after your off.

    lol manny

  5. Do you actually have anything but adolescent crap to contribute?
  6. Ahh, he is an adolescent. :LOL: :LOL:
  7. all home now smee? msg too short

  8. Yer mate
    All safe and sound
    Now to put to use my earplugs.
  9. If your uni's internet is behind a proxy, some applications such as msn, are able to run off some proxies. You can find the proxy settings under internet options in ie, or connection preference in firefox.

    If there is a proxy, but is restricted to a select set of ports, then the only way to get around it is to set up an SSL server which allows port forwarding on your home computer. What you can do then is to use an SSL client like putty, connect to your home computer, and set up the SSL port tunnelling.

    If you didn't get what I just said, put simply all the internet connections are encrypted, passes through the firewall as 'legitimate traffic', routed through to your home computer, and then rerouted onto the internet; as opposed to trying to connect straight to the internet, and being blocked by the firewall.

    For example, pop3 mail servers uses port 110. Say your uni firewall blocks 110, so you can't use connect to your mail server. But say the uni firewall allows port 22. Port 22 is a general SSL port. So here's how you'd do it.

    You connect to your home computer using SSL.

    At home, you set up the following on the SSL server:

    Local (home internet) mail.someisp.com.au:110
    <------> Remote (uni) workstation123.university.edu.au:1234

    Now mail traffic gets passed in both directions from your home internet, through the SSL tunnel, to the computer at uni. On the university computer, you set up your mail server in outlook to be:

    localhost means you connect to yourself. What it really means is that you connect to yourself, which is then passed through your SSL Client program, then sent to your home computer, where it then gives it to mail.someisp.com.au:110.

    Note though, that the speeds wouldn't be as fast as connect straight to the internet, because this method requires alot of packet overhead, and the encryption and decryption also takes time as well. But that's how you'd do it. So you need to go and google up an SSL Server to install on your computer, and then get 'Putty', the SSL Client program.
  10. fantastic...

    i will get some advice on your advice :)

    thanks alot sounds promising
  11. Sure you don't mean SSH?
  12. whoops, my bad, I meant SSH. I just spent the last nine hours straight doing my programming assignment; brain's a bit fried -_-.
  13. no.

    You would be thanking me if you had a porno blocker on your PC.
  14. bwahahahahahahahahahaha
  15. Until Uni goes and blocks the SSH ports too, or they use LDAP authentication for accessing the Internet. In that case - I wish you luck :D
  16. If you're at Melbourne Uni (Parkville), you can't. There's an MSN gateway that you can use to access MSN, but that's about as far as you'll get for non-web things. The only Internet access you'll get is through the web proxy.

    I'm a systems engineer who studied at Melbourne last semester. I spent a bit of time playing with the wireless network there.

    I've you've got wireless, pop down to e55 on Elizabeth Street. They have free wireless net access - not restricted in any way - as long as you buy a coffee or something.
  17. thanks mipearson.

    i spend alot of time on this thing and may pop down to e55...

    where abouts is it?
  18. #55 Elizabeth St, strangely enough :)

    It's on the West side between Flinders Lane and Collins St.
  19. if the name follows the trend of other bars, its probably 55 elizabeth st, which is near the corner of elizabeth and flinders I think. I might drop by there myself actually :D

    I find it easiest to run ssh and vnc servers on my home computer so I can work directly from it or transfer files to a laptop or uni computer as required. The ssh tunnel is good, but is a bit more trouble.
  20. well if im understanding correctly, i would need a home pc to run the programs and my laptop to access data from it.

    unfortunately i only have my lappy.

    cheers though :)
