Generate SSH Keys
The following was completed on Ubuntu desktop.
- Open 'Passwords and Keys'
- Click add then 'Secure Shell Key'
- Press 'Continue'
- Give your key a description
- Then click 'Just Create Key'
You will be prompted for a 'passphrase', you can leave it blank if you want.
You can also do this quickly from terminal with the following commands;
Enter the following commands;
Additionally create an account with the 'username' command in global config.
Now setup the RSA key;
After entering 'key-string' press enter and put in the SSH key that you generated earlier. Press enter twice when you've copied the key over, and it should show a 'Fingerprint' id
I had a problem with the number of retries allowed when logging in this way (As I created a SSH key for each device, instead of just using one for all of the devices). I cleared this up by removing some RSA keys that I no longer use. You can increase the number of SSH retries, but on the 300 switches the command does not appear.
If you do get a problem logging via ssh in try this;
- ssh -o PubkeyAuthentication=no firstname.lastname@example.org
