If +you rely on these key types, you will have to take corrective action or +risk being locked out. + +Your best option is to generate new keys using strong algos such as rsa +or ecdsa or ed25519. RSA keys will give you the greatest portability +with other clients/servers while ed25519 will get you the best security +with OpenSSH (but requires recent versions of client & server). + +If you are stuck with DSA keys, you can re-enable support locally by +updating your sshd_config and ~/.ssh/config files with lines like so: + PubkeyAcceptedKeyTypes=+ssh-dss + +Be aware though that eventually OpenSSH will drop support for DSA keys +entirely, so this is only a stop gap solution. + +More details can be found on OpenSSH's website: + http://www.openssh.com/legacy.html |
