minimal docker image to create a portable ssh server inside a docker container.
this can be used for proxying, pivoting or just harnessing a shell in any way on a remote system.
a user account user is added, a random password is generated and will be displayed on stdout.
The variable SSH_PUBLIC_KEY can be used to inject your public key
docker run -d -p8022:22 nikosch86/docker-socks
where 8022 is the port you want to connect to, the local socks proxy can be started like this:
ssh -D1080 -p8022 -fN -luser <public_ip>
if you want to use it in proxychains, the config line would look like this:
socks5 127.0.0.1 1080
