When i try to start dnsmasq ,I face the following error dnsmasq: failed to bind DHCP server socket: Adress already in use


Given the information provided I'd say you already have a DHCP server running on that machine.

Perhaps you have started dnsmasq more than once?

Try the following command to see if anything else is acting as a DHCP server on port 67.

sudo netstat -tulpn|grep 67

  • Thank you,, I've got this when typing the command udp 0 0* 474/dnsmasq – ligand Jan 28 '16 at 15:10
  • That just shows that dnsmasq is running. Did you start it? – joan Jan 28 '16 at 15:13
  • No i didn't but i think it's related to dnsmasq-base program thats implemented natively into the os as I read in an other forum – ligand Jan 29 '16 at 16:35
