I've been struggling to get a new install up and running and just can't seem to find the problem with the dhcp not sending. From the syslog it looks like it is shutting down (see below) but from ifconfig AND lshw it seems like all is in order. I repeatedly tried starting and restarting isc-dhcp-server which, according to syslog, does start but then shuts down for lack of finding subnet declaration which is, indeed, there in the etc/ltsp/dhcpd.conf file. After a reboot syslog shows eth1 starting and stopping on its own 6-8 times. What am I doing wrong? Please, can someone help me? edubuntu 12.04 The error reported in syslog is "No subnet declaration for 1 (no IPv4 addresses). Jan 6 14:14:06 brightlearning dhcpd: ** Ignoring requests on 1.
