ACK. But how do you do the checking, if the link is down?
Especially if you have a dsl router in a ethernet subnet.
My subnet consists of three hosts, two of them are bintec routers who do
the dsl stuff. They are reachable, even if the DSL Line is gone.
How would U check that?

Of course, but there is a need for some comprehensive, easy to
understand HOWTO for non-techies... I guess.
Especially when it comes to tc and tcng...
