![]() ![]() Note that you can use this technique to connect to any network service running on home-host, not only sshd. Now, connected in a terminal on remote-host, you can connect to ssh daemon running on home-host with: remote-host $ ssh localhost -p 2222 This socket will forward all packets to home-host:22/tcp via the secure connection established. R 2222:localhost:22 will allocate a socket to listen at localhost:2222/tcp on remote-host. Nf will put ssh client to background without execute any command on server. You can create a persistent reverse ssh tunnel between home and remote hosts with: home-host $ ssh -Nf -R 2222:localhost:22 remote-host If you want to make a ssh connection to your home-host, you need a ssh daemon running on it: # assuming that ssh server is already installed on home-host No SSH tunnels, just straight from my mint laptop: As you can see, there is something wrong between my laptop and the Ubuntu server at home. This can be done with the following command, on the local machine: local: ssh -N -R 123:127.0.0.1:456 10.0.3.12. I run a speed test from my local ISP in Europe, to the same testing site in South FL. The goal is to create a tunnel that will forward TCP traffic from the loopback address on the remote machine on port 123 to the local machine on port 456. usage: sshtunnel -h -U SSHUSERNAME -p SSHPORT -P SSHPASSWORD -R IP:PORT IP:PORT. Now again proxied web browser on my Mint laptop: And finally. Of course you will need to provide correct authentication data to the commands. SSH tunnel established to the windows 10 computer. Once the service is started you should be able to: :~$ ssh localhost -p 22 # connect to the ssh localhost -p 22 # connect to On the other hand autossh will keep it alive much longer than ssh, because it also detects automatically the connection's failures. The service will be restarted automatically if it hangs. SSH from the destination to the source (with public IP) using the command below: ssh -R 19999:localhost:22 sourceuser138.47. You can get the status or restart the service by the following commands. In order to stop and disable the service. sudo nano /etc/systemd/system/rviceĭescription=Keeps an SSH tunnel to '' openĮxecStart=/usr/bin/autossh -M 0 -N -q -o "ServerAliveInterval 60" -o "ServerAliveCountMax 3" ĮxecStop=/usr/bin/killall -s KILL autossh Here is assumed the ssh-server at the both systems listen to the custom port 2222.Īt this stage you should be able to: sudo ssh # orįinally create the service.Don't forget to change the parameters Host, HostName and IdentityFile.Note the SSH key is possession of the root user, because it will be the owner of the service. ![]() Also it uses autossh, so as first step we need to install it. The configuration uses systemd service which is created at the client side. Here is such configuration from one of the servers that I maintain. ![]()
