[Dnsmasq-discuss] dhcp-match option:hostname fails with syntax error

[Benedikt Hochstrasser]

(dnsmasq 2.63 here)

Hi list,

I am currently setting up a small-time staging system for Windows clients.
dnsmasq is to serve PXE requests (which boot a windows PE image) and DHCP
requests from the aforementioned PE image, but should ignore everything
else.

Now, all Windows clients request their addresses with a vendor id "MSFT",
so I cannot ignore all "MSFT" clients. But all PE images generate a host
name in the form of "minint-abcdef" which is supplied in the DHCPDISCOVER
message. So I just have to catch the client-supplied host name and tag it
accordingly, right?

In an earlier post (<
http://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2012q3/006206.html>)
it was discussed how to wildcard-match host names, but when I enter

   dhcp-match=set:winpe, option:hostname, minint-

I get "dnsmasq: bad dhcp-option at line xyz"

If I use

   dhcp-match=set:winpe, option:domain-name, minint-

then I get no error, but of course I won't get an address as the client is
only supplying the hostname (option 12) and not a domain name. (I also
tried host-name, "12" and every other option I could think of. It just
fails when I use the option "hostname" which, according to line 459 in
dhcp-common.c, is the one I should use.) I also ran wireshark and the
client is indeed supplying option 12.

What am I doing wrong?

(here's my config)
