Hello Lonnie,
I'm sorry this is getting more detailed/confused.
Let me explain.
I have two LANS on a Net4801 and I want to control the dhcp server for each
interface independently so that I can set things like the range of IP's; the
router to use; the DNS server to use; etc.
Why?
I want to control how clients (mainly WiFi) using dhcp are managed.
One network (eth1) is mainly VoIP and uses the Net4801 as the gateway.
The other (eth2) has PC's connected and they should _not_ use this gateway but
rather use another router/gateway and at the same time this network's DNS is
managed by a server on that network.
I also have to explain that I have made the move from Astlinux 0.4.4 to 0.7.3
without any intermediary. So, I'm still trying to get my mind around the
relationship between :
/mnt/kd/rc.conf (which doesn't seem to be used any more on my system)
/mnt/kd/rc.conf.d/user.conf (which overrides variables - but I don't know where
these variables are stored)
and "AstLinux GUI" variables in
/mnt/kd/rc.conf.d/gui.firewall.conf
/mnt/kd/rc.conf.d/gui.network.conf
and what should be done by hand and what via the GUI.
When I get this sorted I'll write it up for doc.astlinux.org so that others can
set up a 0.7.3 machine more easily.
So, (PS the range 125:130 is just for testing at the moment)
It looks like I need to change things in several places:
DHCPRANGE in /mnt/kd/rc.conf.d/user.conf
and the various dchp-options in the dnsmasq.static include file
Because if I use a dchp-range in the dnsmasq.static include file then I get this
range in addition to the one set by DHCPRANGE.
On the other hand I didn't yet try setting DHCPRANGE="" and a dhcp-range with a
reload time to see if only the one from dnsmasq.static is used.
I would like to have control over the dhcp retry period as well.
Again sorry that this is getting so detailed.
