Re: Enabling SSD

> PermitRootLogin yes

this is extremely dangerous. have you considered su or sudo?

> PubkeyAuthentication no

this is really easy. try one as an exercise. you can generate public and
private keys pair with a script. then you keep the private key on your own
computer and public key on the remote host. you can protect the key with
password. you can even put the private key on the usb token (i.e. yubikey)
so it's not stored as a file and you carry the key all the times protect it
with a pin and use it for different hosts so you don't have to remember
thousands of passwords :-)
