Now, to allow remote hosts to connect, you need to specify bindaddress in ssh -R, the easiest would be to use for that which means all addresses. A reverse SSH tunnel is an outbound connection from a machine on your network that connects securely over the internet to Stitch. I have tried using both my user's rsa file and the root's rsa file and with none of them I manage to connect. 2 Answers Sorted by: 0 First of all, assuming your tunnel command is ssh -fN -R 2023.

For this, you will need another host (so-called relay host) outside your restrictive home network, which you can connect to via SSH from where you are. The concept of reverse SSH tunneling is simple. If I run the command as root ( sudo) the (empty) password for the rsa file is asked. What is Reverse SSH Tunneling One alternative to SSH port forwarding is reverse SSH tunneling. through teamviewer) I can run the command and no password is asked. I have created the id_rsa.pub file and sent it to the remote-server but still it does not seem to work. However the problem I have is that both commands are asked for a password.
