I use a GPRS connection for Internet, and I use ONSPEED for acceleration (nspeed si really good).

I read the onspeed site and it appears that onspeed is not supported for linux.

Can anyone recommend any internet accelerator / proxy / compression software that work well with linux - and if so what brands of linux are supported?

Thanks

The issue is that you need a server on the "other side" of the GPRS link to do the filtering and compression before the traffic comes over the slow GPRS link to your computer.

I had Linux machines on both sides (in different continents too, which helped with some other reliability problems). I ran privoxy on both sides. The remote privoxy was doing basic ad filtering which really reduces the junk being loaded in a lot of web pages. The local proxy was configured to forward traffic to another port on the localhost. Then, when I was online, I opened an SSH session which forwarded this local port to the privoxy port on the remote host, with compression enabled for the SSH session.

This worked pretty well, but I did not do anything to try to decimate/reduce image content. E.g. a JPEG or PNG image in a web page that is already compressed will not compress further in the SSH gzip stream compression. However, all the HTML will compress quite a bit. There are ways to do that too, but I've never bothered.

Of course, the browser was then configured to talk to the local proxy. It would get errors from the proxy if the SSH link was down, since the local proxy would not be able to contact the remote proxy over the forwarding port.
