I found it very frustrating to have non-blinky network cards and not have ifconfig tell me which one had a "good physical link" when i was learning.
is there an official way to check for the presence of an ethernet cable for
an interface? If I config an interface with ONBOOT=yes but there is no cable
plugged in, it nevertheless configures the interface, which might later
startups such as sendmail waste a lot of time trying to access the
nonfunctional network. It also may keep default routes around that get in
the way if I later fire up the wireless interface. There is a program
mii-tool that can tell you whether the link is up:
Hallo rem, wie gehts?
There is a package ifplugd available from freshrpms or dag ... This is a daemon that monitors an ethernet devices and calls ifup if e.g. a cable is plugged in and ifdown if the cable is unplugged. This works quite well on my notebook.

In the last week i've been pleasantly surprised when trying another open source os, that ifconfig very helpfully lets me know (by default) what interfaces have good physical connections. It's a small thing, but very helpful.
I know now that i could have looked at the tx/rx numbers in linux ifconfig and kinda put together my own picture, but i didn't what "all that stuff was for" - i was new to *nix in general (and network config gui's were uh, not so user friendly at the time).
Anyway question, why has this not been slipped into linux's ifconfig? Or is there something that i don't know about (very, very likely!) that makes this more trouble than it's worth to put in?
Just askin' aloud is all. "Write it in your own self," is an acceptable answer too - i need to make myself more useful :)
