Some non-terminating processes were listening on ports.
On sshd startup, we check whether signing using the SHA1 for signing is
On ssh private key conversion we explicitly use SHA2 for testing RSA keys.
In sshd, when SHA1 signatures are unavailable, we fallback (fall forward :) )
On a client side we permit SHA2-based proofs from server when requested SHA1
We fallback to SHA2 if SHA1 signatures is not available on the client side
We skip dss-related tests (they don't work without SHA1).
