Re: [Dnsmasq-discuss] Different dns config based on network address
Cyro, I think what you want to use is tags. If you read thru the conf file there are numerous references to them. - Jay Sent from my iPhone On Oct 10, 2012, at 9:04, Cyro Wicks wrote: > Hello all, > > I have a firewall and dns server for my entire network, and what i would like > to do is to have dnsmasq to read /etc/hosts_net1 or /etc/hosts_net2 based on > the network address coming from net1 or net2. > > I am trying to implement an internet filtering based on dnsmasq, but i would > like to have net1 users and net2 users with different dns block rules defined > on /etc/hosts_net1 and /etc/hosts_net2 files! > > Is it possible with dnsmasq? > > Thank you very much for any help. > > Cyro > ___ > Dnsmasq-discuss mailing list > Dnsmasq-discuss@lists.thekelleys.org.uk > http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss

I think I read your reply as you want a dhcp and name server for your LAN, right? That is what I have set up right now. A 12.04 desktop VM running in VirtualBox, the NIC is bridged to the host adapter. It works great but I had to fiddle a bit to get the dnsmasq I downloaded with apt-get to run. - Jay Sent from my iPhone On Oct 9, 2012, at 9:06, Chris Green wrote: > On Tue, Oct 09, 2012 at 12:25:41PM +0100, Niall Litchfield wrote: >> Chris >> Did you come across Stephane Graber's website and article >> at [1]http://www.stgraber.org/2012/02/24/dns-in-ubuntu-12-04/ (not sure if > > Yes, I've found and read that.

Re: [Dnsmasq-discuss] How to add local configuration to Network Manager initiated dnsmasq in Ubuntu 12.04
Strange. I installed 12.04 from scratch, and had to install dnsmasq and change it in the NetworkManager. In fact I finally fixed an issue with the Ubuntu machine itself not resolving names outside itself (ie Internet DNS) by changing the line to "dns=dnsmasq,dns" Thus the default on a new install was dns not dnsmasq. I will check the workstation I upgraded to 12.04 later tonight. - Jay Sent from my iPhone On Oct 9, 2012, at 4:39, Chris Green wrote: > On Mon, Oct 08, 2012 at 06:49:38PM -0400, Jay Imerman wrote: >> On Oct 8, 2012, at 14:04, Chris Green wrote: >> >>> I have run dnsmasq with local configuration for quite a while now to >>> provide local DNS services on my home LAN. >>> >>> I am now upgrading my machines to [xl]ubuntu 12.04 and in this version >>> dnsmasq is run automatically by Network Manager.

Re: [Dnsmasq-discuss] System tries to get its address by DHCP before dnsmasq starts up - how to stop it?
There is a NetworkManager.conf file, in there the line dns= should Jane dnsmasq as the setting. I haven't noticed any delays in my setup, same thing: 12.04 with static IP v4 settings, it is nice and snappy. - Jay Sent from my iPhone On Oct 4, 2012, at 11:04, Dan Williams wrote: > On Thu, 2012-10-04 at 12:20 +0100, Chris Green wrote: >> On Thu, Oct 04, 2012 at 10:23:33AM +0100, Chris Green wrote: >>> I have a little server system running dnsmasq version 2.59 under Ubuntu >>> 12.04 (I have just upgraded it from Ubuntu 10.04). >>> >>> While booting it tries to get its network configuration (using DHCP >>> presumably) from the LAN, since *it's* the DHCP server this doesn't work >>> but it wastes a lot of time waiting for things to time out and produces >>> various error messages on the way. >>> >>> How do I configure the system so that it doesn't do this? >> Further to this the delay is cause by /etc/init/failsafe.conf, even if I >> have static IP correctly configured in /etc/network/interfaces the silly >> init sequence still does all the waits in /etc/init/failsafe.conf >> waiting for DHCP. >> >> Google searches just produce the standard way to set up static IP but >> no workaround for the delays. > > Is the machine running NetworkManager?

Re: [Dnsmasq-discuss] Pulling DHCP leases from an external script?
I'm not 100% certain, but the way I read the man page, the script is triggered after the dnsmasq event occurs, so you can pass some custom behavior to a script after dnsmasq has managed the lease. However, it sounds like you want to customize dnsmasq behavior and insert your own algorithm for allocating IP addresses? Just out of curiosity, why? You can specify quite a complex set of allocation rules using tags and more, why would you need to have anything other than that? _______ Jay Imerman T (248) 230-4373 | F (952) 255-2056 4067 Highview Court Waterford, MI 48329-4712 <http://twitter.com/#%21/jimerman> <http://www.linkedin.com/profile/view?id=15203444&trk=tab_pro> <http://www.facebook.com/jay.imerman> On Wed, Oct 3, 2012 at 3:14 PM, Brian Rak wrote: > I'm trying to set up a DHCP server so that on any request for a new lease > I can execute a script and have the script return an IP address (and other > information). > > Is this something that is currently possible with dnsmasq?
