Try 192.168.1.0 / 255.255.255.0

typo - your net is 192.168.2.0 / 255.255.255.0

I tried both suggestions, singly, and both together though I didn't
think the forward slash in lieu of "netmask" was right. (I have another
subnet declaration just above the one it's complaining about that uses
"netmask", not a "/", and it doesn't gripe about that one, and that's
the way it's written in the sample dhcpd.conf file that is buried down
in the dhcpd doc folder in /usr/share/doc/dhcp-4.2.3).
Nothing worked. It's so strange...

192.168.2.1 is not a subnet, 192.168.2.0 is
yup, changed that, and now the error is different, but the service is
still failing - it reports:
Not configured to listen on any interfaces!
my whole dhcpd.conf file:
option domain-name "fedoraleesburg.local";
option domain-name-servers 151.197.0.38, 199.45.32.38;

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.

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. -- Claude Jones Brunswick, MD, USA -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

The owner of the bug from Redhat responded in timely fashion and suggested a few things. I discovered that the file permissions had been set to root:root and I changed them to dhcpd:dhcpd - then, I discovered that the dhcpd service had been disabled at some point along the way. Running "systemctl enable dhcpd.service" as root set it to autostart at boot. After making those two changes and rebooting, I now have dhcp server working again.
