I disagree. Let me explain myself:

A fresh installation of nagios3 has this configured in
/etc/nagios3/conf.d/services_nagios2.cfg :

| # check that ssh services are running
| define service {
|         hostgroup_name                  ssh-servers
|         service_description             SSH
|         check_command                   check_ssh
|         use                             generic-service
|         notification_interval           0 ; set > 0 if you want to be renotified
| }

Then, nagios-plugins-basic creates /etc/nagios-plugins/config/ssh.cfg
with this:

| # 'check_ssh' command definition
| define command{
|         command_name    check_ssh
|         command_line    /usr/lib/nagios/plugins/check_ssh '$HOSTADDRESS$' '$ARG1$'
|         }

So, the output of the /usr/lib/nagios/plugins/check_ssh plugin may be
correct, but one of those two files is wrong, because that extra (emtpy)
'$ARG1$' argument is going to mark a perfectly working ssh server in an
unknown state.
