[Dnsmasq-discuss] tell window$-xp about NO netbios?

Hi,

my problem is connecting a window$-xp box via ad-hoc wlan.  It seems xp
cannot connect ad-hoc with WPA, only WEP.  Then xp goes on to ask the
"main" host about all sorts of netbios services and won't finish
associating.  I have no experience whatsoever with window$.

This is a log from 2.53test29:

  available DHCP range: 192.168.3.2 -- 192.168.3.14
  client provides name: bie

What does this name mean?  Is this the hostname set there?

  vendor class: MSFT 5.0

When matching vendor-class, is it enough to match "MSFT" or do I need to
match "MSFT 5.0"?

The xp box sees the wlan, connects and picks up its IP, but then asks
the host questions via netbios.  Currently I have this is
etc/dnsmasq.conf:

  # wlan 192.168.3.0/28
  dhcp-range=wlan,192.168.3.2,192.168.3.14,255.255.255.240,192.168.3.15,1h
  dhcp-option = net:wlan, option:dns-server, 192.168.53.1
  dhcp-option = net:wlan, option:router, 192.168.3.1
  
  #dhcp-host=id:bie,00:25:d3:6d:ac:30,sirah,192.168.3.5,30m
  dhcp-host=xx:xx:xx:xx:xx:xx,somebody,192.168.3.5,30m,net:wlan
  
  # vendor class: MSFT 5.0
  dhcp-option=vendor:MSFT,2,1i
  dhcp-option=44 # set netbios-over-TCP/IP nameserver(s) aka WINS server(s)
  dhcp-option=45 # netbios datagram distribution server
  dhcp-option=46,8           # netbios node type

I'm going to convert the "net:x" tags to the new tagging system, in the
meantime:  will xp understand the empty 44 and 45 dhcp options as "no
netbios here, just use regular DNS-over-UDP"?
