Using the TCD Proxy from outside College

Jim_No.6

I used to use the TCD proxy all the time from outside college to access websites that TCD subscribes to. eg. oed.com
I can't seem to get it to work any more. Any advice from people who have it working?

Things I've tried:
1 - Pointing Firefox's Automatic Configuration to http://www.tcd.ie/proxy.cgi
Externally: This gets no proxy setting
Internally: This returns proxyA.tcd.ie:8080 or proxyB.tcd.ie:8080

2 - Pointing Firefox's s Automatic Configuration to http://www.tcd.ie/proxy.pac
This returns proxy2.tcd.ie:8001 or proxy1.tcd.ie:8001

3 - Thread on Boards.ie
Mentions tcdproxy.tcd.ie:8080

None of the proxies I've listed here seem to work manually (or with the automated scripts).
Does anyone have this working from home? What are your settings?

proxy4.tcd.ie port 8002.

Additionally you can set up a tunnel through wilde to the cs proxy.

ssh -L 2222:www-proxy.cs.tcd.ie:8080 wilde.cs.tcd.ie

Set the proxy in firefox to localhost and port 2222. Now all you firefox traffic goes view the tunnel.

ssh syntax was wrong.

This was the library one, but has since been disabled.

Undergrads have no access to wilde.

Possible with macneill?



EDIT: You could always find hosting inside tcd and stick a php based proxy on that.

Boston

Proxy4 is still in operation. Jim there has access to wilde, but you can replace wilde with spoon.netsoc.tcd.ie if you like.

Well maybe its just staff and postgrads then.

My login won't work anymore, and it used to work flawlessly.

Boston

Ah I get you. No idea if it works, but the server is still up.

Aye.

Would you do me a favour and see if you can login please?

I can't.


I have the forwarding through wilde though, so that's good enough for me. Thanks guys

Boston

Syntax is correct now. proxy is the destination, wilde is the middle man.

They changed this all around this year. You just append .elib.tcd.ie to the hostname of the resource, log in and you're away.

OED is available at http://dictionary.oed.com.elib.tcd.ie/ - for example. Just sign in with your proxy password there. No actual browser proxies required.

I give up.

I can't get tunnelling to work, whether it be through netsoc or macneill

Prolly coz you're only an engineer...

Boston

Netsoc should work, that's definitely the command. Don't forget to set you proxy to localhost and port 2222.

And you are only half a cs student :P




EDIT: Maybe that wasn't a jibe at being an engineer, but rather having different permissions... If so, I apologise

I'm not that bad :rolleyes:


Nothing is working.

Boston

I see the problem. All the ports need to be accessible form both side, in your case you can only see port 22 from your home machine.

ssh -L 22:www-proxy.cs.tcd.ie:8080 macneill.cs.tcd.ie -l username should work

ssh -L 22:www-proxy.cs.tcd.ie:8080 spoon.netsoc.tcd.ie -l username does work

It was kinda both :P

Randomness

Agh ignorance is bliss, I have no idea what yall are talking about.

That would make sense.

Also didn't help that firefox doesn't recognise localhost but wasnt telling me. Had to key in 127.0.0.1 instead.

Nothing much I can do about that error tho..




EDIT:
Working grand using the netsoc proxy. :pac:

Been down that blind alley myself.

For those who don't know what we're talking about, start the ssh tunnel as above and in Firefox do:
Edit > Preferences > Network > Settings > Manual Proxy Configuration
HTTP Proxy: 127.0.0.1
Port: 22

ISS must love students engaging in a bit of aul tunnelling.

Boston

Fuk ISS, I ran this by the Comp Sci tech guys and they said they had no problem with it, in fact they recommended that I do it.

Brian

This allows you to ... ? Besides look up words in the OED, I mean. Bypass the Rapidshit limit?

Boston

Bless yer heart bazza.

There are sites out there, reference ones mostly, that require users to pay a subscription to access the content. Trinity has done this on behalf of the students for many of these sites. Using the proxy (or the other method I suggested above) proves that you are a genuine TCD student, and gives you access.

never mind folks!

Also could mean you could watch RTE while abroad I guess? Get around all that geoblocking nonscense?

Yes.


I watched the All Ireland in france last year.

Snap! But i was in a pub. Really got to get this working now with another browser, might choose opera...

Finally someone talking in English!

Brian

Some obliging UK University wouldn't happen to offer a similar thing? Bit o' iPlayer?

Boston

No.

How and ever, there are hundreds of open proxy servers in the UK, find one and you are set.

Brian

Hmm, I was under the impression that they were kinda too slow for vidya streaming actually...

Boston

Does it matter if you're buffering?

Brian

Very true.

Ron DMC

You could always trade login details with a friend in a British university.
You'd get bbc iplayer and they'd get eh... the crappy Rte player.

Jonathan

I haven't been able to get that to work for me.

The ads load and then nothing..

Crash

Unless they've changed how iPlayer works, if you use a proxy its only used for the authentication stage. As its a distributed system in the backend, all connections are then direct - hence no problem with using a slow ****ty open proxy.

So is there a definitive way to do this?

Just wanna watch RTE.IE through firefox, opera whatever and wondering whats the proxy address and settings for a normal student, i.e. one not oin engineering, C.S. etc., one with normal access rights?

It was proxy4.tcd.ie:8002 but ISS have done away with it.

Any student can join netsoc.

Pretty much most of what has been discussed here was over my head, but I thought I'd contribute anyway. Using Chrome if I don't remember to uncheck the manual proxy settings when I get home, it still connects via the TCD proxy. Is this kinda what you're on about?

Kinda but not really.

The reason that it still works at home is because the connection times out and looks to connect directly (using your home broadband). What we are talking about here is to make the computer look as if it is still in TCD (using a TCD ip address) from home.

devinejay

Ah well that makes sense, it does take ages to connect when I leave TCD settings on, just timing out each time I guess. Also out of curiosity I did a connection speed test comparison between what I thought was the TCD proxy and my own, and there was practically no difference.

Jonathan

Yea it times out before it attempts to connect directly.

When it realises it cannot find the .pac file, it will connect at normal speed.

devinejay

All this interwebbery - she'll reveal her secrets to me yet!


Although I'm pretty sure I don't want to know them all...

M450

That would have been fairly useful while in Chicago over the summer... was pissed when I couldn't watch any GAA. And you have to wait a few days to watch the Sunday Game so you're always a week behind!!! That doesn't make any sense for them to do that!

You get access to the .pac if you are outside college, but as I said in my original post, the "Outsider .pac" returns an instruction not to use a proxy.

If you are using the wireless network as devinejay was, ISS instruct you to use http://proxypac.tcd.ie/accelerated_pac_base.pac which is not accessible from outside college.
