I have a cleanly installed Edubuntu 11.04 server in the classic 2-NIC
format. I realized after installation, but before I tried to connect
any thin clients, that it was better to reverse the NICs so the Intel
one was running the thin clients. I was able to successfully do so
via modification of /etc/udev/rules.d/70-persistent-net.rules and
reversing the two lines.
Now I wanted to try to book a thin client. Took a switch and plugged
the LTSP NIC from the server and a thin client into the switch. And
the thin client fails to PXE boot -- can't find the DHCPD server.
Ideally I'd like eth0 to be the Internet NIC and eth1 to be the LTSP
NIC on the 10.x.x.x. subnet.
So I hunted around and find that the dhcpd3 service is not running.
Every time I try to run it on the server I get:
sudo service isc-dhcp-server start:
* Starting ISC DHCP server dhcpd
* check syslog for diagnostics. [fail]
Checking syslog I get:
eduLTSP dhcpd: Wrote 0 leases to leases file.
eduLTSP dhcpd: No subnet declaration for eth1 (no IPv4 addresses).
eduLTSP dhcpd: ** Ignoring requests on eth1. If this is not what
eduLTSP dhcpd: you want, please write a subnet declaration
eduLTSP dhcpd: in your dhcpd.conf file for the network segment
eduLTSP dhcpd: to which interface eth1 is attached. **
eduLTSP dhcpd: Not configured to listen on any interfaces!
I've tried to search online and tried a bunch of steps but been unable
to resolve this! Here are the relevant configuration files:
jbishay@i7-eduLTSP:~$ cat /etc/networks
# symbolic names for networks, see networks(5) for more information
jbishay@i7-eduLTSP:/etc/network$ cat interfaces
iface lo inet loopback
