Hi im using ubuntu server 12.04 at work. My office has two proxy servers through which I access the internet - XXX.XXX.XXX.108 and XXX.XXX.XXX.9. I made the necessary proxy settings using XXX.XXX.XXX.108 and everything works properly. However When I use the XXX.XXX.XXX.9 I get an authentication error(e.g while executing wget). Please note that the credentials Im supplying are absolutely correct. And using the same XXX.XXX.XXX.9 proxy and the credentials Im able to access internet through Firefox and Chrome on a windows machine.

What might be the problem?

Thanks in advance!
