ssh -L8021:<dist>:21 <host>
Remote forwarding (you need to set “GatewayPorts yes” in sshd_config if you want to access the port from other addresses than localhost, then ”/etc/init.d/sshd reload”):
ssh -R8021:<dist>:21 <host>
Use another machine as a proxy, turning localhost into a SOCKS proxy, eg on port 8080:
ssh [-fN] -D8080 <host>
It may be a good idea to open a ssh server on a web port (80/8080/443), because you will need to use this when you have a restricted connection, and port 22 may be forbidden as well (just add
Port 22 AND
Port 80 to sshd_config, or configure NAT port forwarding on your router, and then use
ssh -p <port> <host>…).
Then configure your apps to use it:
# just to prevent from trying to use the proxy when you want to establish the proxy: Host <host> ProxyCommand socat STDIO TCP:%h:%p # for using the proxy for everything else: Host * ProxyCommand socat STDIO SOCKS4:localhost:%h:%p,socksport=8080
[Proxy Settings] ProxyType=1 socksProxy=socks://localhost:8080
server = localhost server_type = 5 server_port = 8080
Then start your application with tsocks to force it to use the proxy:
You can do something similar and maybe more powerful with proxychains.
RSYNC protocol proxy:
export RSYNC_CONNECT_PROG='ssh <host> nc %H 873'
Forward all the traffic so you don't have to configure every application.
sshuttle --dns -r <host> 0/0 -x 10.0.0.0/8
0/0 is the forward mask (everything), -x is the exclude mask (local network), –dns forwards the DNS requests as well. See also option –no-latency-control for better bandwidth but higher latency, and ”–python /usr/bin/python” if you get error message “P=python2: Command not found. P: Undefined variable.”.
