![]() One of the good things is that with two VPSs from different suppliers in different locations it will still be able to connect if one of those VPS fails and you won't even notice because it does this automatically. One advantage of using external VPSs and having a PI from home connect to them is that I don't have to worry about any port forwarding on the router.Ĭonfiguring tinc takes a bit of getting used to, but once you have the basics of setting up the secure keys you can just forget about it and it is transparent to use. All you have to do at home (once the tunnel is built up) is to SSH on the server to the forwarded port (as shown later) onto localhost. Also I can access the VPSs via their .y addresses as well as using their public addresses. All "local" ports are usable, not just SSH. I can then access any of my home systems in exactly the same way as if I were there. ![]() To connect you have to add -N to ssh this will build a tunnel but doesn't try to open a shell. ssh/authorizedkeys, but add in front command/bin/false ssh-rsa. On your strato server add the public key into. When I am away from home I start tinc on my laptop and it connects to either of the VPSs and gives my laptop a virtual network port with the same .y IP address as if I were using it at home. Create a new (tunnel) key on the raspberry, only to build the reverse tunnel to your strato server. The Pi connects to both of the VPSs so they appear to be on my internal network with .y addresses as well as their public IPs. On your laptop: ssh usernamelocalhost -p 10000 (username is the Pi username) This will connect to the Pi via the webserver. All data is wrapped with encrypted SSH tunnel. ssh -f -N -R 10000:localhost:22 usernameipaddressofwebserver Now the webserver is listening on port 10000 and forwarding to the pi on port 22. To extend the analogy, think of encryption as paint that. If you think of protocols are tubes that connect the internet together, think of SSH tunneling as a smaller tube inside a larger tube. Longer explanation: everything over SSH is encrypted. I have the same software on a Pi at home. Support all Linux machines and TCP services such as SSH, VNC, RDP and HTTP. Re: SSH Tunnel and port forwarding question. I have installed tinc (A mesh VPN) on both of them. PING raspberrypi.local (192.168.197.117): 56 data bytesĦ4 bytes from 192.168.197.117: icmp_seq=0 ttl=64 time=15.038 msĦ4 bytes from 192.168.197.117: icmp_seq=1 ttl=64 time=14.All this SSH tunnelling seems like a difficult way of doing things to me, but possibly the way I do things could seem tricky to set up too. Use the following command: ping raspberrypi.local ~ % ping raspberrypi.local Access your Raspberry Pi projects from anywhere. So, to begin with we will ping the RPI, and if the RPI is reachable (and running an mDNS server and your client machine running an mDNS client), the IP will be shown, as seen down below. SSH console client on Mac/Linux: ssh -p 12345 Where. ![]() The way you enter the connection details. Now open your SSH client, and connect to the your 'Available At' address. SSH in turn needs the IP address of the RPi. Testing your tunnel Go to the Custom Tunnels page and find out the world-wide accessible address for your tunnel. Note: Before you begin, make sure to enable SSH either manually through the RPI interface in the Raspberry Pi Configuration or through the command sudo raspi-config and Interfacing OptionsĪlso make sure to be on the same wifi, both your PC and RPI in order to connect.Ī freshly installed RPi comes with the hostname known as “ raspberrypi “ which is widely used to connect to the RPI commandline using the secure shell (SSH) protocol.
