ssh as SOCKS server

Assume three computers A, B, and C. A can connect to B via ssh, but A cannot connect to C, but B can connect to C.

A -> B -> C

On A open ssh as SOCKS-server with

ssh -N -D 9020 user@B

Now on A one can use

brave --proxy-server="socks5://localhost:9020"

The browser will then show up as if directly surfing on B thereby circumventing the limitations on A.

Instead of the brave browser, one can use Chromium, or Firefox. Option "-N": Do not execute a remote command.
