[Dnsmasq-discuss] Setting BOOTP "magic cookie"

[Tyler Reese]

I'm trying to construct a dnsmasq BOOTP reply to match what I am getting using the bootp-dd2 server.

In a wireshark BOOTP trace, it shows a "Magic cookie" attribute which are the first 4 bytes of the "Bootp vendor specific options".  When using bootpd, I can use 'vm=rfc1084' in the desired entry in /etc/bootptab.  This results in the 4 bytes being set to 0x63825363.  After these 4 bytes, the rest of the options follow...and they are decoded in the wireshark packet view.

Using dnsmasq, what is the equivalent way to set those first 4 bytes to 0x63825363?  I am able to set the rest of the following options using dhcp-option, but I can't figure out how to set those first 4 bytes.

Thanks,
Tyler
