This change adds two new Rex exceptions and changes the local comm to raise the right one depending on the circumstances. The problem with the existing model is
that failed binds and failed connections both raised the same exception. This change is backwards compatible with modules that rescue Rex::AddressInUse in additi
on to Rex::ConnectionError. There were two corner cases that rescued Rex::AddressInUse specifically:
1. The 'r'-services mixin and modules caught the old exception when handling bind errors. These have been updated to use BindFailed
2. The meterpreter client had a catch for the old exception when the socket reports a bad destination (usually a network connection dropped). This has been updat
ed to use InvalidDestination as that was the intention prior to this change.
Since AddressInUse was part of ConnectionError, modules and mixins which caught both in the same rescue have been updated to just catch ConnectionError.
See the complaint on #4039. This doesn't fix that particular
issue (it's somewhat unrelated), but does solve around
a file parsing problem reported by @void-in
Keyboard-interactive method isn't required to exploit Tectia SSH.
So this update will just go straight to password method. There's
also improvements for the check() method: Not only does it check
the SSH version (banner), it will also check and see if the server
is using password method to auth.
