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-128 code 128 = string; option option-129 code 129 = text; option option-221 code 221 = text; shared-network DESKTOPS { option subnet-mask 255.255.0.0; option broadcast-address 10.179.0.255; option routers 10.179.1.1; option netbios-name-servers 10.179.2.9; option netbios-node-type 2; option domain-name-servers 10.179.2.6; option domain-name "<a href="http://ncs.k12.de.us">ncs.k12.de.us</a>"; subnet 10.179.0.0 netmask 255.255.0.0 { range 10.179.3.100 10.179.3.253; #use-host-decl-names on; get-lease-hostnames true; option log-servers 10.179.2.12; } } shared-network WORKSTATIONS { option subnet-mask 255.255.255.0; option broadcast-address 192.168.0.255; option routers 192.168.0.254; option routers 192.168.0.254; option domain-name-servers 192.168.0.254; option domain-name "ltsp"; next-server 192.168.0.254; option root-path "192.168.0.254:/opt/ltsp/i386"; subnet 192.168.0.0 netmask 255.255.255.0 { range dynamic-bootp 192.168.0.005 192.168.0.125; #use-host-decl-names on; get-lease-hostnames true; option log-servers 192.168.0.254; # trick from Peter Rundle <<a href="mailto:peter.rundle@au.interpath.net">peter.rundle@au.interpath.net</a>> # newer Macs if substring (option vendor-class-identifier, 0, 9) = "AAPLBSDPC" { filename "yaboot"; option vendor-class-identifier "AAPLBSDPC"; } # really old iMacs elsif substring (option option-221, 0, 5) = "Apple" { filename "yaboot"; option vendor-class-identifier "AAPLBSDPC"; } # Intel PXE elsif substring (option vendor-class-identifier, 0, 9) = "PXEClient" { # NOTE: kernels are specified in /tftpboot/lts/pxe/pxelinux.cfg/ filename "/lts/pxe/pxelinux.0"; } # default to an i386 BOOTP image else { filename "/lts/vmlinuz.ltsp"; } if substring (option vendor-class-identifier, 20, 3) = "ppc" { option root-path "192.168.0.254:/opt/ltsp/ppc"; } else { option root-path "192.168.0.254:/opt/ltsp/i386"; } } } # example configurations for specifying specific kernels to specific clients group { use-host-decl-names on; option log-servers 192.168.0.254; host ws001 { hardware ethernet 00:40:63:cb:08:88; fixed-address 192.168.0.1; filename "/lts/pxe/pxelinux.0"; } } <div class="gmail_quote">On Fri, Feb 5, 2010 at 10:38 AM, James Huffman <<a href="mailto:cwerks@yahoo.com">cwerks@yahoo.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> I am trying to install another network card to handle terminal traffic better. Is it possible to add a second card to the terminals? (Would this be 2 networks?) this is the only option I think I have other that running a (3 deep) daisy chain that is really slowwww...It seems to me that it should be, but alas, I can not find a way...I am running Centos. If this is an option, can someone please either tell me how or at least send me to a tutorial on this subject? Thanks!
