user and pass are correct.
I haven't tried a stratum proxy yet. Will try that next.
Since you are running linux you can use the latest version of BFGminer and it has an internal getwork server.
Was easy to set up and has been working flawlessly. It's nice to control all of my ASIC's from one "miner."
Slushs mining proxy is also very easy to set up.
Either way it's going to work best to run something local on your network as a "bridge" between your getwork blade and a stratum server.
