I don't see anything about your config file that looks wrong (although I suggest posting stuff like that and source code in [CODE] [/CODE] tags to preserve readability). What happens if you swap the postions of the two subnet stanzas within the file? Does the server actually work correctly? Are you sure the error message is current, and not from some prior configuration? It might be helpful to post the details of your software & version.

Welcome to LinuxQuestions.

What linux distribution/version are you running?

You need to specify the interface in the dhcpd.conf file by adding dhcdpargs=eth1 or eth0 i.e. whatever adapter is attached to your local LAN. If your network is more complicated please post the details.
