After upgrading to Ubuntu 16.04, I found myself unable to log into MikroTik routers via ssh - mine and clients'. Most of the systems I support are on 5.24. The problem is that ssh no longer supports DSA by default. I'm not sure what the best solution is. By telling ssh to use DSA and also to allow smaller groups, I could get to a password prompt, but publickey logins still didn't work. These lines in ssh_config in a Host stanza or (not so good) globally:    HostkeyAlgorithms +ssh-dss    KexAlgorithms diffie-hellman-group14-sha1 My current solution is to upgrade to RouterOS 6.36 and add an RSA public key. RSA has been supported since 6.31.
