Ah. I'll play just for funsies.
BTW while you not bother with the first tier of support, or possibly even
the second, you also have to be prepared to answer everything in their
script. For example with Comcast I start with already rebooting the box,
releasing DHCP, and the like.

Directory that maps IP (or other network) addresses to physical addresses.
Only functions on the local network inside the route. Non routable.
Broadcast call/response with caching and timeout.

6 AFAICR. Zero halts. 6 Reboots. I'm an everyday Linux user and I haven't
looked at an init table in a long long time. Ctrl-Alt-Del abstracts the

Agreed. And ifconfig does have a bit of difference between different

Private IP address. Non routable.

Nothing in today's network. Sigh. Virtually everyone fails to respond to
ICMP packets anymore because of security concerns.

Facilitates the movement of packets from one network to another. Can't do
that with (or send to the wrong network) with broken/missing entries.

You mean it's not? ;-)
This was fun. The real question is what are the techs supposed to support?
It's likely at this point I would fail a Windows test in this same
ballpark. Every time I mess with a broken Windows box (which is just about
the only time that I do) I have to refigure out how to access everything.
