Well sshdos (useless since it is protocol 1.5) and ssh2dos (protocol 2.0)
look pretty close to useless by now.  Last update to ssh2dos was in 2006.
ssh and security has moved on in the last 12 years.

For example last yearh people were having issues
connecting to new openssh versions with it:

Openssh simply doesn't allow the outdated key methods that ancient ssh
client wants anymore because they have been found to be insecure.
But I see you were part of that discussion so you already know about
those problems.

I guess freedos could use an updated ssh client.
