[Nagiosplug-devel] check_iftable - Submission

Hey everyone,
    Ah-ha! I did find a difference. Now I remember why I did it this 
way. My script also checks the ifConnectorPresent attribute, and doesn't 
send out an alert if a connector is not present. This prevents it from 
sending out an error on "virtual" interfaces that are usually down, like 
dial-out ports.

    Sorry, that's the difference. :)

    Thanks,
    Rob
