Cannot connect SSH to device using Raspberry internet.

[KeramxD]

Thanks for wifi-to-eth-route.sh! It's amazing and works. I shared internet from Raspberry Pi to another linux device. Internet works. My raspberry has ip 192.168.1.xxx. Another linux device has 192.168.2.55 and I cannot connect to it via SSH from my local network. If I connect this device directly to router via ethernet it works.

What should I do to connect via SSH to Linux device that uses internet from Raspberry Pi? :)

Thank you!

Can you ssh into the raspberry pi? If so watch this video. Go to 7:25 in and do the ssh port forwarding. The computer you are trying to access is technically on a different network so you need to port forward from the raspberry pi that is “on” the different network.

Yes, I can ssh to Raspberry Pi without issue. I cannot ssh into linux device that is connected to Raspberry Pi via ethernet. Cannot ssh directly from Raspberry Pi and another PC from local network.

So when you are connect to the raspberry you you can’t ssh into the 192.168.2.55 IP from the raspberry pi?

[KeramxD]

Correct. But when I plug this device directly to router and it get IP 192.168.1.XXX I can connect from any device so SSH on this device works. SSH does not work when device is connected to Raspberry with IP 192.168.2.XXX

Strange, I will see if I can recreate the situation and get back. In the mean time someone else might be more help.

I would like you to open two terminals

First Terminal:

ssh -N -T -L 2222:192.168.2.55:22 [email protected](raspberry-ip)

Second Terminal:

ssh -p 2222 <remote-user>@localhost

The first one will open tunnel via Raspberry and will forward port 22 of 192.168.2.55 to your local system on port 2222. It will not output anything on screen.

The second is basically SSHing into port 2222. If it works then fine or else we will have to debug further

I started first terminal. There was nothing for long time. When I did it one more time I see: marek@Air-Marek ~ % ssh -N -T -L 2222:192.168.2.55:22 [email protected] [email protected]'s password: bind [127.0.0.1]:2222: Address already in use channel_setup_fwd_listener_tcpip: cannot listen to port: 2222 Could not request local forwarding.

Second terminal shows nothing.

The first will not output anything. For the second, it should work. Looks like I will need to simulate the setup on RPi.

When I ran ssh -N -T -L 2222:192.168.2.85:22 [email protected] it worked becuae when i did the second terminal I was able to login ssh -p 2222 install@localhost

192.168.2.85 - IP of the Ubuntu Computer install - user for Ubuntu Computer 192.168.1.79 - pi IP pi - user for raspberry pi 2222 the port that we passed through to the local machine linked to Ubuntu machines port 22 passed through the raspberry pi

I also used putty to ssh into the pi

cat /var/lib/misc/dnsmasq.leases to get the ip of the machine then once inside the pi terminal I did ssh <username>@<ip of machine> ssh [email protected] and that also worked as well for me

@KeramxD Any update? Also after reading your post more you can change the SSh forwarding from 2222 to really any port. 2222 might already be in use on your machine for something else. Maybe try 8080? This is used for most https websites and if 8080 was in use on your machine then surfing the net would become a lot more difficult.

Maybe try: ssh -N -T -L 8080:192.168.2.55:22 [email protected]
