Re: DNS-DHCP solution for linux?
I'm not quite sure what you mean. For me, dhcpcd does assign a DNS server
via the /etc/dhcp/resolv.conf which it generates. However, it does not
update several other things I would like it to and it does change some
things I would like it to leave alone. In order to update these things, I
use the dhcpcd -c option in /etc/init.d/dhcpc like this:
"start-stop-daemon --start --quiet --exec $DAEMON -- -c /etc/dhcpc/fix_netstuff $IFACE"
I have included my fix_netstuff script. It updates various things, maybe
it will be a help to someone. It is set up for _my_ computer, you'll have
to alter it if you mean to use it. It is fairly sloppy, I'm no shell
script master.
