DHCP Error Message

Tags: , ,

We have one machine setup as a gateway, dns and dhcp server which connect by 3 network card and different subnet.

Today, my colleague was told me there is an error message in /var/log/message

Hmmm… there is a mistake.

If you have more than one network card resides in the DHCP server, it is recommended to specify which interface(s) the DHCP server will use. Edit /etc/sysconfig/dhcpd by adding the appropriate interface to the DHCPDARGS= line. The entry in /etc/sysconfig/dhcpd should appear as follows:

Example:
/etc/sysconfig/dhcpd
DHCPDARGS=eth1

Restart the DHCP server and it’s working now!
