Hi everybody,

I'm new on this list, i use the dhcp side of dnsmasq on a private 
network to manage 40 win2k computers with restricted access (and static 

Today i tried to use the #252 dhcp option that allow to (indirectly) 
configure proxy options on workstations, this option doesn't give the 
proxy adress/port but the URL of an auto-configuration script that gives 
proxy settings.


It didn't work, so i made a network capture with Ethereal to see which 
DHCP options were really send during the DHCP dialog and the #252 option 
was missing.

After a quick look a the sources it *seems* that this option is not 
implemented yet. As far as dnsmasq was starting fine even with a dhcp 
configuration it didn't support, i think it could be a good idea to 
write a warning to syslog in this kind of case, just to inform which 
dhcp options will be dropped.

Any comment is welcomed,

All the Best
