[SOLVED] Network config when link is up.

[bastibasti]

I use my laptop on wlan and sometimes on wired net. My companys dhcp takes about 12 seconds to answer (some windows machine) so I cannot adjust the timeout on the dhcp. Is there a way to skip dhcp when media is not up!?

I'm using preup and ethtool in /etc/conf.d/net as follows:

preup() {
# Test for link on the interface prior to bringing it up. This
# only works on some network adapters and requires the ethtool
# package to be installed.
if ethtool "${IFACE}" | grep -q 'Link detected: no'; then
ewarn "No link on ${IFACE}, aborting configuration"
return 1
fi
}

That should do what you want...

If you install sys-apps/netplug network interfaces won't be brought up until they are plugged in. No configuration is required beyond installing the package, as Gentoo's net-scripts already know about it.

I tried ipflugd, it works like a charm. Thank you!!

@lookitsme: Thanks for your preup script i had to add a sleep 2 to the beginning, the nic on this machine is very lame )
