I have an Ubuntu server running which was working fine till now. I can't SSH into the server and get the following error:



Connecting to user@10.10.0.6...
OpenSSH_7.8p1, OpenSSL 1.0.2k 26 Jan 2017

I also tried logging into another machine on the same network and ssh into Ubuntu server from that machine and it still does not work. Any ideas on what might be going on and how to resolve it?

  • I think you need to create your ssh keys on teh servier... I think it's sshkeygen

  • Thanks, I am away from the server, but I'll try it. It's funny how it stopped working all by itself. I have the exchanged the keys in the past but I never disabled password login.

You may need to login to the server directly and generate your ssh keys:



$ ssh-keygen


This will ask some questions so you can set up your key.



Do this on your client machine as well.



There is more info available here.



You may also need to reinstall openssh:



$ sudo apt install --reinstall openssh-server openssh-client
