Whatever you select there doesn't make any difference for LTSP. It's for clients declared in /etc/nbd-client, and LTSP doesn't use that file. > (still as > * ltsp-config dnsmasq > > worked... then I quickly unplugged the cable because it said, > "*Restarting DNS forwarder and DHCP server dnsmasq".

I'm not sure what you mean there or how it was technically achieved. But when running `ltsp-config dnsmasq`, you should have had already configured your server IP addresses, so that it would automatically create a proper /etc/dnsmasq.d/ltsp-server-dnsmasq.conf for you: "It's recommended that you setup your network first. A static IP is suggested but not required for single NIC setups. If you're using a dual NIC setup, configure the internal NIC to 192.168.67.1.

You're correct though in that this information is missing from the https://help.ubuntu.com/community/UbuntuLTSP wiki (although it isn't strictly LTSP-specific either). So... let's start an "an answer for a wiki page" initiative: I'll be answering some questions like this one in the mailing list, and people that receive the answers should then create nice wiki pages for others to get helped as well! :) So if you do write an https://help.ubuntu.com/community/UbuntuLTSP/StaticIP wiki page about it, I'll put a link to it from the ltsp-pnp wiki page. There are 2 methods to configure a static IP for your server. One, with network manager, and second, from /etc/network/interfaces. For "headless" servers the second method is preferred, but for schools where the teachers are working on the server I suggest going with the first one, so that the teachers can easily see the network properties from the gnome applet (connection speed, up/down status...) Network manager method: Read this: http://www.liberiangeek.net/2010/03/how-to-configure-a-static-ip-address-in-ubuntu/ Copy or create some similar pictures for the UbuntuLTSP wiki page. Some additional remarks: * The "[v] Make connection available for all users" setting should be checked, otherwise the connection only starts after the teacher logs in on the server. * The http://www.liberiangeek.net/wp-content/uploads/2010/09/static_ip_mav_23.png picture applies for single NIC installations. * For dual NIC installations, the internal NIC should have no DNS server entries, and for gateway it should have 0.0.0.0. Again the "[v] Make connection available for all users" setting should be checked. /etc/network/interfaces method: Don't read what's written in the www.liberiangeek.net/2010/03/how-to-configure-a-static-ip-address-in-ubuntu/ page, don't disable network manager like it suggests etc. For single NIC cases, put something like this in /etc/network/interfaces: iface eth0 inet static address 192.168.3.3 netmask 255.255.255.0 gateway 192.168.3.1 dns-search example.com dns-nameservers 192.168.3.45 192.168.8.10 For dual nic cases, the internal NIC entry should be like this: iface eth1 inet static address 192.168.67.1 netmask 255.255.255.0 That's all, if you configure your network _before_ following the ltsp-pnp installation steps, then `ltsp-config dnsmasq` will create an appropriate /etc/dnsmasq.d/ltsp-server-dnsmasq.conf for you. If you do it afterwards, just re-run: ltsp-config dnsmasq --overwrite Warning: the generated /etc/dnsmasq.d/ltsp-server-dnsmasq.conf has proxy-dhcp mode enabled for the external NIC. So, clients in your "external" network will be able to be netbooted as ltsp clients. If you don't want that, you should remove the respective dhcp-range=192.168.3.0,proxy line from that file. Cheers, let's see if the "an answer for a wiki page" initiative can work! :) -- edubuntu-users mailing list edubuntu-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/edubuntu-users
