Bad range, adress xx.xx not in subnet xx.xx?

Question

ubuntu

Good morning! I work as a web developer in one organization, and some time ago I became an enikey developer, without the right to choose. There is a need to configure the server
1.proxy
2.dhcp
3.sambaFiles
Ubuntu server 14.04 dhcpd.conf File contents --- /etc/default/isc-dhcp-server File contents I get the following error: bad range, address 192.168.8.20 not in subnet 192.168.8.0 netmask 255.255.255.255 How to solve this, thanks!

Answer 1

in /etc/interfaces and /etc/dhcp/dhcpd.conf you have the network mask set to 255.255.255.255 , which means that your interface can only communicate with the router ( point-to-point ) i.e. with himself in this case, which is not suitable for your purposes at all.
Change the mask, for example, to 255.255.255.0 in both files and everything should start)

Answer 2

The mask 255.255.255.0 will be more correct for the locale. Edit in interfaces file
