$ ssh -o HostKeyAlgorithms=ecdsa-sha2-nistp256 trollheim-nokД®rror calculating host key WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!

Then try it вЂ¦ and watch it fail: # -nok is an alias in ~/.ssh/config to disable Kerberos To put into the template for new system users, and to put into DNS.

We need to know the new identity of the server, so that we know what to compare against,ДЄnd know what to advertise to the system users in an update email, Then add the contents of ~/.ssh/id_ecdsa.pub to ~/.ssh/authorized_keys. So that all three keys can be loaded at once with one passphrase. Run ssh-agent via your normal means and then invoke ssh-add to confirm that you really did use the same passphrase for the ECDSA key as for RSA & DSA, Your public key has been saved in /home/troll/.ssh/id_ecdsa.pub. Your identification has been saved in /home/troll/.ssh/id_ecdsa. % ssh-keygen -t ecdsa -C public/private ecdsa key pair.Д®nter file in which to save the key (/home/troll/.ssh/id_ecdsa):Д®nter passphrase (empty for no passphrase): Via your preferred config management system. Then explicitly add вЂњ HostKeyВ /etc/ssh/ssh_host_ecdsa_keyвЂќ to /etc/ssh/sshd_config, OpenSSH вЂњ makeВ installвЂќ depends upon the host-key target, # ssh-keygen -t ecdsa -f /etc/ssh/ssh_host_ecdsa_key -N '' IвЂ™m writing it up so I have a reference to point people to. Mostly very simple to do because of the normally-high skill of the developers of OpenSSH but there was one glitch. So, time to add ECDSA to my running OpenSSH setup, so that if thereвЂ™s ever a reason to disable RSA and/or DSA, I still have a way in. I am put in mind of baskets, containing all of ones eggs.

OpenSSH now (release 5.7) supports some elliptic curve cryptography!Д®xcellent to have modern crypto, and something not based on prime number factorisation. ThereвЂ™s a longer tale of trials and tribulations involved in a requisite Heimdal update which I had wisely put off,
