How to set Option 66 and Option 67 for DHCP in isc-dhcp-server?

  • 066 Boot Server Host Name
  • 067 Bootfile Name
  • Could you please add a little more detail? What exactly did you do, what did you want to achieve and what happened instead? Did you encounter any warning or error messages? Please reproduce them in their entirety in your question. You can select, copy and paste terminal content and most dialogue messages in Ubuntu. (see How do I ask a good question?) – David Foerster Jan 22 '17 at 1:41

I should edit dhcpd.conf file

nano -w /etc/dhcp/dhcpd.conf

and to add the following entries for activating the option 66 and 67.

#option 66
option tftp-server-name "w.x.y.z";

#option 67
option bootfile-name "test.cfg";

Then to restart the DHCP Server.

sudo service isc-dhcp-server restart

  • man dhcp-options option tftp-server-name text; This option is used to identify a TFTP server and, if sup- ported by the client, should have the same effect as the server-name declaration. BOOTP clients are unlikely to support this option. Some DHCP clients will support it, and others actually require it. – emoxam Apr 1 at 14:02

man dhcpd.conf

   next-server server-name;

   The next-server statement is  used  to  specify  the  host
   address  of  the  server  from which the initial boot file
   (specified in the filename statement)  is  to  be  loaded.
   Server-name  should  be  a  numeric IP address or a domain
