I'm on macOS Big Sur 11.6 and am using macOS's builtin SSH tool to access the Kerla demo. I've added it permanently to a list of known hosts but have to enter the password "kerla" to login.

Suggestion:

Add the password to the README file.

The password is not checked. You can enter any "password", including the empty one.

As @aprosvetova pointed out, password is not checked (arbitrary string including empty one is accepted). This is because, it seems SSH protocol does not provide a without authentication mode. I'd remove that if I could by the way.

Thanks for the reply! However, when I just press enter, the connection is cut. Could just be a "me" issue.

I cannot reproduce the issue. If possible, could you share the result of ssh -vvv (note: it will expose your public key) if it's still reproducible?

Tried to do it again, and it works as intended. Sorry for the inconvenience!

Please don't be sorry at all! Perhaps, you hit a hidden bug in Kerla as it's still not matured. Feel free to reopen if you got the same issue :)
