I'm new to Linux systems. I recently installed 12.04 LTS and it works fine, but I have a problem.
I live in the university dorms and in order to use Internet, I have to put proxy settings which require authentication. I had a problem with downloading from the store but I read the solution you wrote here still sometimes it works. I don't know why.
But the big problem is, if I want to open any link from inside the university, I have to disable the proxy, on Windows there were an exception for using the proxy you can easily do it. Is there any possible way of doing that in Ubuntu 12.04?
