Subject: dhcp 4.2.0-P2 and LDAP: No subnet declaration for eth0
Hello,
I have trouble running dhcp with ldap. Starting the service end into
the well known error message "No subnet declaration for eth0
(172.17.5.254)."
So I checked the network settings, ldap.conf and dhcp config in the
ldap-tree several times but I can't find the missing or wrong entry in
my configs.
Weeks ago, I had nearly the same config running on Fedora 13 with
dhcpd-4.1x without any problems. But this one makes me crazy:
* Here are the facts:
I compiled and installed dhcpd 4.2.0-p2 --with-ldapcrypto on Centos
5.5 without any erros or warnings and copied the dhcp.schema to ldaps
schema directory. (with slapd.conf include entry).

For me the subnet declaration seems to contain all necessary
instructions. The interface eth0 is up and running.
I have no idea how find out whats wrong with the subnet declaration.
Is there a new 'interface' option ?
Any help or hint would be appreciated !

Jürgen

Dear Jürgen,
Can you check the logfile "/var/log/dhcp-ldap-startup.log".
There you should be able to see with what the dhcp server is starting up with.
