This will enable ssh login instantly. Check that it has worked by logging in to the expo server like this: + +$ ssh expo@expo.survex.com + +

If it didn't work

You may get this response if the public key has not been loaded properly on the server or if your laptop has not loaded the secret key properly. + +expo@expo.survex.com: Permission denied (publickey). + +

  1. Check that ssh-keygen has put both files into your Linux home .ssh folder on your laptop, +if not, then move them there: + +$ mv id_rsa_wsl* ~/.ssh + +where id_rsa_wsl is the 'file in which to save the key' you specified above. +

  2. Check that the ssh agent process is running and fix it if it is not (full details of how to do this +give at www.ssh.com/academy/ssh/agent) + +$ ssh-add -l + +and if the process is not running, start it like this + +$ eval `ssh-agent` + +Check that the key is loaded by running ssh-add -l and then test that you can login again. +

If it still doesn't work, read the online +documentation, start from scratch, and do it all again but this time using all the defaults and without trying to be clever.
