Hi,

I'm trying to use my sheevaplug to set up a tunnel using ssh so that I can securely browse the web on public wifi etc.

I followed the tutorial here using the following command:

Code:
ssh -p 2222 -D localhost:12000 matt@dyndns.address

ssh logs into the sheevaplug with no problems, but when I enable the socks proxy using post 12000, Firefox comes up with the error page
"The proxy server is refusing connection

Firefox is configured to use a proxy server that is refusing connections."

Any ideas on why I can't get the sheevaplug to accept the connection?

Thanks,

Matt

p.s. here's the log when the command is run, just in case that helps.

I've got it working - for some reason putting 127.0.0.1 instead of localhost into the firefox connection settings makes all the difference!
