Hi.

Maybe it's just me, but it happens every now and then that I lock out
myself of a system because of wrong ListenAddress lines, i.e. addresses
sshd cannot bind to.

It would be nice if sshd would ignore these errors, but for security
reasons of course *only* if it can bind to at least one of the named
addresses (or if it would instead NOT simply bind to the wildcard
address).

At least right now I don't see any security implications of this
behavioural change.


Cheers,
Chris.
