{{From|https://help.ubuntu.com/community/UEC/Tips}} {{Languages|UbuntuHelp:UEC/Tips}} The goal of this page is to document little tips or tricks for working with [[UbuntuHelp:UEC|UEC]] that don't fit other places. ==== Multiple DHCP Servers / MAC Filtering ==== The installation of a CloudController adds a dhcp server to the network. It is managed and will only respond to instances. However, if you have another dhcp server on your same network, it may also respond, which could wreak havoc. Eucalyptus creates its instances with MAC addresses starting with '''<code><nowiki>d0:0d</nowiki></code>'''. This means that you can configure the other dhcp server on the network to ignore instance requests by filtering on that MAC address. This can be accomplished in dnsmasq (used by dd-wrt or other wrt projects) by adding the following to the config: <pre><nowiki> dhcp-host=d0:0d:*:*:*:*,ignore </nowiki></pre> [[category:UbuntuHelp]]
