I have been battling this for several hours and coming stuck.

I use windows XP and a VM box with ubuntu. I have to use the proxy to connect to the internet at work. However I use ubunutu to check development code.

Some info Xp machine has a proxy setup and no internet browsing problems with XP machine VM Network setup as bridged connection and the proxy set to the same IP that the XP machine uses.

First problem firefox keeps prompting me for proxy auth? However if I ignore it it does let me get through however its temper*mental* and stops altogether?

enter image description here

Also the wget command is working for

but it isnt for or

So I have a flakey internet connection on the VM and it must be something to do with how I have set it up. Not sure what my options are? Install a proxy server on my XP host machine that sends requests to the main proxy?..

I managed to resolve it by entering in my windows logon onto the firefox popup. It seemed to have made the proxy accept future requests even if not from firefox such as wget
