[Dnsmasq-discuss] Set environment variable for dhcp-script

[Daniel Weller]

Ok sure. I am trying to pass DHCP header option 161 OPTION_MUD_URL_V4 to the dhcp-script. Doing so would allow for the use of dnsmasq to communicate a MUD url via DHCP to a mud manager.


Thanks,


Daniel

mmmm, I was hoping for an answer like

} I do mis DNSMASQ_FOO. FOO is a custom DHCP option, being option number ....
} Having DNSMASQ_FOO in dhcp-script would solve the problem of ...


Without knowing the original problem is not possible to provide
an alternative solution.

Without knowng the DHCP option number is not possible to advice
which existing DHCP option to use as starting point for the currently
missing source code for putting FOO into environment for dhcp-script.
