DHCP Server Problem
Is it possible to setup a DHCP server that lends a range of ips to a subnet where the DHCP server doesn't have the interface?
For example the DHCP server is setup to a red hat box with only one interface card with ip 165.65.110.99.
The /etc/dhcp/dhcpd.conf is:
DHCPDARGS=eth0;
subnet 192.168.100.0 netmask 255.255.255.0 {
option routers 192.168.100.1;
option subnet-mask 255.255.255.0;
option domain-name "lsnet.ucla.edu";
option domain-name-servers 164.67.7.60, 164.67.60.60;
option time-offset -8;
range 192.168.100.11 192.168.100.100;
range 192.168.100.110 192.168.100.200;
}
# reservation example
host apex {
option host-name "test.lifesci.ucla.edu";
hardware ethernet 00:A0:78:8E:9E:AA;
fixed-address 192.168.6.47;
}
DHCPDARGS=eth0;
subnet 192.168.100.0 netmask 255.255.255.0 {
option routers 192.168.100.1;
option subnet-mask 255.255.255.0;
option domain-name "lsnet.ucla.edu";
option domain-name-servers 164.67.7.60, 164.67.60.60;
option time-offset -8;
range 192.168.100.11 192.168.100.100;
range 192.168.100.110 192.168.100.200;
}
# reservation example
host apex {
option host-name "test.lifesci.ucla.edu";
hardware ethernet 00:A0:78:8E:9E:AA;
fixed-address 192.168.6.47;
}
DHCPDARGS=eth0;
subnet 192.168.100.0 netmask 255.255.255.0 {
option routers 192.168.100.1;
option subnet-mask 255.255.255.0;
option domain-name "lsnet.mydomain.org";
option domain-name-servers 165.67.7.60, 165.67.60.60;
option time-offset -8;
range 192.168.100.11 192.168.100.100;
range 192.168.100.110 192.168.100.200;
}
# reservation example
host apex {
option host-name "test.mydomain.org";
hardware ethernet 00:A0:78:8E:9D:AA;
fixed-address 192.168.6.47;
}
The red hat box where I'm running the DHCP server doesn't have a defined interfact to the newtowk 192.168.100.0.
After I start the service I get this in the /var/log/messages

Could anybody shed some light on what is wrong on m configuration?
Thanks
