[Dnsmasq-discuss] Cannot send dhcp option 12 hostname to clients

[Kevin Flynn]

Hello everyone.

I'm currently working on a small home network voip system, and I cannot 
for the life of me figure out how to get dnsmasq to send dhcp option 12 
hostnames to clients. I've tried all the obvious methods, including 
/etc/ethers, dhcp-hostsfile entries, dhcp-ignore-names, 
dhcp-generate-names, tag sets, etc. with no luck.

As I was searching the list archices, I noticed a comment from Simon 
mentioning that dnsmasq will not send a dhcp option 12 hostname to a 
client if the client sends a hostname to dnsmasq, and none of my 
configuration attempts seem to be able to override this behavior.

The reason for attempting this, is that I have 2 voip ata adapters, 
which are Linksys/Cisco SPA3000 and they are configured by default to 
send the hostname "SipuraSPA." and I am attempting to configure and 
provision these devices automatically, as opposed to logging into each 
device individually everytime they need to be configured.

So in summary, is there any way to tell dnsmasq to send a dhcp option 12 
hostname to a client reliably, everytime, regardless of what the client 
is sending ?

Thanks in advance.
