If you don't want DHCP to acquire an address for an interface, but you
still want to get DHCP-related parameters, you can run this:
# ifconfig <interface> dhcp inform
Then use /sbin/dhcpinfo to retrieve the variables (perhaps using
/etc/dhcp/eventhook to know *when* to do so). For WPAD, that'd be:
# /sbin/dhcpinfo -i <interface> WPAD
... after setting the system up to understand WPAD:
# echo "WPAD SITE, 252, ASCII, 1, 0, sdmi" >> /etc/dhcp/inittab
Granted, that's not quite what you're asking for. I understand the
desire to send a "simple" DHCP query and get a response without
getting into using a stateful daemon, but we don't have a feature
exactly like that.
