I have installed isc-dhcp-server, and I wish to using this dhcp server as wireless hotspot. I have the following dhcpd.conf file in /etc/dhcp/dhcpd.conf

ddns-update-style none; 
option domain-name-servers,;
log-facility local7;
subnet netmask { 
option routers; 
option subnet-mask; 
option domain-name-servers,; 

I run the following command

sudo dhcpd -t /etc/dhcp/dhcpd.conf 

It gives the following output

interface name too long (is 20).
