Re: [Dnsmasq-discuss] dhcp-broadcast

[Tyler Reese]

User error.

I am on RHEL 5, and it comes with dnsmasq-2.45.  The executable is located at 
/usr/sbin/dnsmasq.

I downloaded dnsmasq-2.55 (to get the dhcp-broadcast option) and ran 'make 
install'.  That put the 2.55 executable at /usr/local/sbin/dnsmasq.

The file /etc/init.d/dnsmasq is what I am using to start and stop dnsmasq.  
That file was referencing /usr/sbin/dnsmasq, and 2.45 didn't know anything 
about dhcp-broadcast.  I fixed /etc/init.d/dnsmasq so that it references 
/usr/local/sbin/dnsmasq.  Now, I can just add 'dhcp-broadcast' to 
/etc/dnsmasq.conf and it works as expected.

It was working from the command line because 'which dnsmasq' showed 
/usr/local/sbin/dnsmasq.

I tried this, but it made no difference.  Should it matter if a dnsmasq 
configuration option is in dnsmasq.conf or another file?

When I run 'dnsmasq --dhcp-broadcast' from the command line, it works as 
expected (unconditionally set the broadcast flag, which is what I need).
I also see this line in the log file:
Sep 20 16:59:44 adminportal dnsmasq-dhcp[25074]: 0 broadcast response
No matter how I try to set the option in the configuration file, I don't get a 
broadcast response.
I don't know the correct syntax for using this option in a configuration file 
(dnsmasq.conf or any other specified file).

The timeout error is suppressed if only the final ACK is missing.

Re: [Dnsmasq-discuss] dnsmasq, mfsBSD, status refused

[Samuel Martín Moro]

Hi,


I tried to associate hostnames with IPs in the hosts file.
And it worked...

With my linux gate, declaring hosts (mac,ip,name,lease) in one line works
perfectly...
I don't understand why it won't with FreeBSD...

Whatever, sorry for the disturbance :)

I find that quite acceptable.  At the same time I'd appreciate if the

[Dnsmasq-discuss] dhcp-broadcast

[Tyler Reese]

I'm trying to use this option to force the broadcast bootp flag to be set on 
bootp replies.  The only way I am able to make it work is to run 'dnsmasq 
--dhcp-broadcast' from the command line.  I want the dhcp-broadcast option to 
be used unconditionally.

I haven't found the correct way to add dhcp-broadcast to dnsmasq.conf in order 
to achieve the same thing.

In dnsmasq.conf, I have tried:
dhcp-broadcast
dhcp-broadcast=bootp

After making the change, I restart dnsmasq.  Neither one is making the 
broadcast bit get set, but again, it does work when I run dnsmasq from the 
command line.  What am I missing?  This is on dnsmasq-2.55.

Thanks,
Tyler
