Linux Dhcp Proxy

is specific to Ubuntu versions 8.04, 8.10, 9.04, 9.10, 10.04, 12.04 If you find this information applicable to additional versions/releases, please edit this page and modify this header to https://ubuntuforums.org/showthread.php?t=916680 reflect that. Please also include any necessary modifications for this information to apply to the additional versions. Introduction A proxy DHCP server is defined by the PXE specification as a server which sends auxiliary boot information to clients, like the boot filename, tftp server or rootpath, but leaves the task of IP leasing to the normal DHCP https://help.ubuntu.com/community/UbuntuLTSP/ProxyDHCP server. This functionality perfectly matches certain LTSP configurations where an external, unmodifiable DHCP server is present (e.g. a router). Getting a recent dnsmasq version The usual dhcp3-server can't be configured to act as a proxy DHCP server; fortunately, the newest dnsmasq versions (>=2.48) support this functionality. Karmic comes with dnsmasq 2.49; for previous Ubuntu versions read on. You can find a backport of dnsmasq 2.49 in this PPA: https://launchpad.net/~ts.sch.gr/+archive/ppa; you may either download the appropriate dnsmasq.deb file for your Ubuntu series, or insert the PPA to your apt sources: echo "deb http://ppa.launchpad.net/ts.sch.gr/ppa/ubuntu jaunty main deb-src http://ppa.launchpad.net/ts.sch.gr/ppa/ubuntu jaunty main" \ | sudo tee /etc/apt/sources.list.d/ts.sch.gr-ppa-jaunty.list > /dev/null sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 03AFA832 sudo apt-get updateThe example above is for jaunty, replace with intrepid or hardy as appropriate. *Note: 12.04 users should have a good working dnsmasq program already in the repositories. Installing dnsmasq and removing ltsp-server-standalone If you've installed your LTSP server using the alternate CD, then ltsp-server-standalone was automatically installed. This package depends on dhcp3-server which would co
