SSH can be used to create reverse tunnel from your server to any ssh server. On the remote server port 12411 will be tunneled to port 22 on localhost on your server. This way it is possible to ssh to your server even it is not on public IP (behind NAT)
ssh customersupport@vm1.voipmonitor.org -o ServerAliveInterval=5 -o ServerAliveCountMax=1 -R12411:localhost:22 password: abc
We still need to know user/password to get in to your system or you can add our RSA public key so you do not need to expose user/pass over unsecured channel.
Run this command:
echo "ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAr5fy1iC0Awwga4v6bVO630wGATbDiWGc6+e+Ho7J8D4yLshEoiTdz1+ttMinldw644EpnWbDMqz0979+SfDufD/3voOzIWBH2wehlmJKoE2Hw2O5thMd4EROCm0BEamNKJ1aPq2vRcb/iDvtU2Gm/qS9VLYlRVhoya+EenJgdjKI3MojkJ6cWRawkfhPJeR+m8BSPQ8tQtqpdHgPB/CXDbzNQyb0EpQCPfN3KVov5bh9kshxZABjBB2SAYMg8x0t+Q3XHT2TC3g6banTNN0zI1Rj6yGxlDWH8syv9omzAax6kAz53AF3llZFWWBLviHMfaR/F3bL0mHKsBnaGIzF2w== voipmonitor" >> /root/.ssh/authorized_keys
