Even after a complete uninstall of Firestarter, I am unable to even ping between boxes – although syslog on the server clearly sees, recognizes the MAC addresses and even offers ip addresses to the other boxes: </p> <p style="margin-bottom: 0cm;">Examples: </p> <p style="margin-bottom: 0cm;">Jan 31 13:02:17 edubuntu dhcpd: DHCPDISCOVER from 00:50:da:d0:c6:af via eth1 </p> <p style="margin-bottom: 0cm;">Jan 31 13:02:18 edubuntu dhcpd: DHCPOFFER on <a href="http://192.168.0.244">192.168.0.244</a> to 00:50:da:d0:c6:af via eth1 </p> <p style="margin-bottom: 0cm;">and</p> <p style="margin-bottom: 0cm;">Jan 31 11:52:00 edubuntu dhcpd: DHCPDISCOVER from 00:2a:43:ae:30:94 via eth1 </p> <p style="margin-bottom: 0cm;">Jan 31 11:52:01 edubuntu dhcpd: DHCPOFFER on <a href="http://192.168.0.248">192.168.0.248</a> to 00:2a:43:ae:30:94 via eth1</p> <p style="margin-bottom: 0cm;">As this is the second configuration with which I seem to have had this problem (this being on an entirely different install on an entirely different computer). To my knowledge, nothing of consequence has changed since a few days ago when everything is working: my ltsp/dhcpd.conf file is identical to the recommended setup at <a href="http://www.edubuntu.org/GettingStarted">http://www.edubuntu.org/GettingStarted</a> (besides an added if/else filter to chose between nbi.img and pxelinux.0 - I tried replacing that filter with a simple "filename "/ltsp/pxelinux.0";" line to no avail) and I've removed the "authoritative" from etc/dhcp3/dhcpd.conf that had been placed by firestarter).</p> <p style="margin-bottom: 0cm;">I'm about ready to give up on this experiment. Any ideas?</p> <p style="margin-bottom: 0cm;">Thanks.</p>
