Some further info....
After a while trying last night, I managed to connect from home using my ISP.
Still can't connect through the company proxy this morning, so I set up a dial-up proxy to my ISP using a modem. It's getting through with a few "S@H did not reply" errors etc. I hope my company haven't managed to stop me uploading/downloading through the proxy, hopefully it's just coincidence and my ISP has lower ping times to the SETI server or something..
Anybody have the IP address of the SETI data server ????
cheers,
Col
