</div></blockquote></div><br>Even though with bad configuration they can cause a lot of confusion and disruption it can be done safely. My router is handing out IPs using dhcp, but cannot parse the PXE options. On my MythTV backend I have setup a dhcp server that does not assign IPs except for a list of mac addresses it knows. The following works for me (obfuscated domainnames and IPs):<br>
<br>#<br># DHCP Server Configuration file.<br># see /usr/share/doc/dhcp*/dhcpd.conf.sample<br>#<br><br># option definitions common to all supported networks...<br>option domain-name "<a href="http://somedomain.net">somedomain.net</a>";<br>
option domain-name-servers 192.168.1.254;<br>option routers 192.168.1.253;<br>option ntp-servers 192.168.1.2;<br>option tcode code 101 = text;<br>option tcode "Europe/Amsterdam";<br><br>subnet 192.168.1.0 netmask 255.255.255.0 {<br>
}<br><br>default-lease-time 600;<br>max-lease-time 7200;<br><br>ddns-update-style none;<br><br># Required by MiniMyth<br>use-host-decl-names on;<br><br>host epia {<br> hardware ethernet 30:40:50:60:70:80;<br> fixed-address <a href="http://epia.somedomain.net">epia.somedomain.net</a>;<br>
filename "pxelinux.0";<br> server-name "<a href="http://mythbackend.somedomain.net">mythbackend.somedomain.net</a>";<br> next-server 192.168.1.2;<br>}<br><br><br><br>The list of host declarations can be expanded as needed. I would not reccommend this setup as running two instances can easily cause trouble, but it works for me and I can safely have my Mythbackend go offline while letting my laptop go online based on the info provided by the router's dhcp server.<br>
