[K12OSN] Installing Multiple network cards Centos

[David Hopkins]

James,

It can be done with channel bonding and probably by just adding the card as
a second card on a new 192 network.  IMHO James Kinney is the person that
really knows the channel bonding setup with K12LTSP CentOS (Sorry for
putting JK on the spot).  Google for chanel bonding.  I'd pick channel
bonding as the way to go.

But ... as for a second network, that should be possible by adding another
network. Below is how my dhcpd-k12ltsp.conf file is set up on a system I
have.  It handles dhcp on the main network (10.) for the Windows systems,
and also is still the dhcp server for the thin clients on 192.168.0.x
network.  I suppose you could change my Desktop section (10.) to be a
different 192.168.1.x network by just copying the workstation section and
changing the IP addresses, then add the correct entries in /etc/hosts and
have it also work.  Then, again, that might break everything.  I do know
that this setup works very well for me and I am using samba as a PDC
(10.179.2.9) with this DHCP setup.

dhcpd-k12ltsp with two networks:

default-lease-time            86400;
max-lease-time                86400;
ddns-update-style none;
allow booting;
allow bootp;

   option option-129 code 129 = text;
   option option-221 code 221 = text;
