I looked at the file and it was set to "DHCPDARGS=eth1" which is my 
internet NIC; so, I changed that to "DHCPDARGS=eth2" which is my LAN 
NIC, and to your question as to whether I have such an address as 
192.168.2.1, I do, and according to Network Manager, that NIC is 
"connected".

The previous errors being reported in "var/log/messages", the incorrect 
subnet error, and the "Not configured to listen on any interfaces!" 
error, are resolved now.

A new error now being reported is this: "Can't open 
/var/lib/dhcpd/dhcpd.leases for append." and then results in "Unit 
dhcpd.service entered failed state." - I navigated to that file using 
Konqueror running as root, and the file is there and I was able to open 
it just fine...could this be Selinux causing the "unable to open"? I 
just checked sealerts and there are none...

The strange thing about all this is that this was all working the last 
time I had a computer behind this box - it's been awhile but I don't 
know why I would have changed that /sysconfig/dhcpd setting over the 
past months...the mislabeled subnet was probably me when I was trying 
various things to troubleshoot this.
