I don't know much about network configuration, but I would like to setup a wifi network in order to ssh between 2 machines running ubuntu. Both machines have their own wifi cards. They will be operating outdoors with no existing wifi or internet access. I am interested in solutions for both short and long range connections. Thank you.

You need some kind of network connection between the two devices for ssh to work.

You can ssh to a computer on a local network with:

ssh [email protected]

I know this works for devices connected to the same router. I'd presume it's the same situation if you connected the two computers with a cat5/ethernet cable.

  • In addition to needing a network connection, you also need to install the openssh-server package on the machines that will be receiving ssh connections, and openssh-client on the machines where you will be running the ssh command. You can install both packages on both machines.

  • Thanks T. Zack and John. I've used openssh to connect on existing networks, but it has failed when I have tried to create my own network and ssh over it. I need to connect wirelessly, one computer will be on a drone. From what I've been reading I think the solution will involve using some type of wireless AP to boost the network I create.

  • You can try setting up a Wifi hotspot on one of the machines. Ubuntu supports this
