For testing purposes, I would like to enable DSA authentication on my server (let's name it A).
If I remove all the key pairs located under
/etc/ssh, both RSA and DSA key pairs are generated on sshd restart.
The consequence is that, if I try to open a SSH connection from a server B to this server A, the following message is displayed :
The authenticity of host '...' can't be established. RSA key fingerprint is ... Are you sure you want to continue connecting (yes/no)?
Do you know a way to disable the RSA authentication so that my server B uses the DSA to authentify on server A ?
