reverse_ssh_raspberry

# You need a server acessible from the client and server (aws instance for example accessible on port ssh 22 )

# install autossh ( apt-get install autossh)
# on the local machine (raspberry pi )

autossh -M 10001 -f -N -R 10000:localhost:22 user@serverip
# -n Redirects stdin from /dev/null (actually, prevents reading from stdin).  This must be used when ssh is run in the background
# -N Do not execute a remote command.  This is useful for just forwarding ports
# -T Do not  allocate a pseudo-tty on the remote system
# -R Set up the tunnel as a reverse tunnel.

# on the server : 
ssh -p 10000 root@localhost
