[Bug 995984] [NEW] check_ssh incorrectly refusing -6 switch even though Usage announces it

[Kilian Krause]

Public bug reported:

When trying to run check_ssh on 12.04 against a dual stack DNS record
the outcome is the following:

$ check_ssh hostname
SSH OK - OpenSSH_5.9p1 Debian-5ubuntu1 (protocol 2.0)
$ check_ssh -4 hostname
SSH OK - OpenSSH_5.9p1 Debian-5ubuntu1 (protocol 2.0)
$ check_ssh -6 hostname
Usage:
check_ssh [-46] [-t <timeout>] [-r <remote version>] [-p <port>] <host>
$

This works ok on 10.04 LTS and obviously got broken somewhere in between
10.04 and 12.04.
