http://ubuntuforums.org – Making server for school. ISP is PPPoe. internet-modem/router-server-WAN(eth0)-LAN(eth2)-switch-clients. eth0 is dhcp. eth2 is static 10.10.0.1 255.255.255.0. I am attemting to use dnsmasq to create dns caching and dhcp on LAN. I commented out dns-dnsmasq in NM, downloaded and installed dnsmasq, and configured dnsmasq.conf, but no caching and no dhcp. If clients are set to static ip and gateway, etc. then they go to internet fine. dig shows repeated 50ms to google.com and client shows "unknown network no internet" when i re-set the properties to dhcp.

Stories similar to [64 bit] Need dns cache-dnsmasq

I am trying to set up a small "lab" at home. Like many modern homes, I have a regular DSL service which comes with a 2Wire 3600HGV router, which acts also as a DHCP server.

I am sharing internet from eth1 to eth2. I do this by editing the eth2 properties and setting method to Shared to other computers.

I also use dnsmasq for dns caching. Now if I enable Internet sharing I have to stop the existing dnsmasq instance as network manager starts its own dnsmasq instance. But this new dnsmasq instance has no dns caching options.

Now my dns query is taking more time.

I've got a problem with dnsmasq on my server everything but dns works on it, it currently gives out dhcp fine and points to the router etc however when i go to a website it wont find it, the dns is pointed to the server on the client machines.

dnsmasq is a lightweight, open-source DNS forwarder and DHCP server. In this article we go through how to prepare the system in order to run dnsmasq and also how to configure the latter as a caching-only DNS server. A configuration file is also provided as a drop-in replacement for the default dnsmasq.conf that ships with your system.

Dnsmasq is a lightweight server designed to provide DNS (and optionally DHCP and TFTP) services to a small-scale network. It can serve the names of local machines which are not in the global DNS.

after I install libvirt-bin and ubuntu-virt-server etc, my resolv.conf auto reset by dnsmasq about every hour

I haven't install network-manager and resolvconf and I search for dnsmasq, only dnsmasq-base have been installed.

when I try to remove dnsmasq-base, libvirt-bin will be removed automatically

how to keep dns config not be changed?

So I've configured my home connections to work with dnsmasq since it bundles a dhcp server with it and is quite nice to set up.

There is another package - isc-dhcp-... that also does this and perhaps is its intended purpose.

What am I losing out on?

dnsmasq can do a three-some: DHCP, TFTP, and DNS. Most modem/router-boxes do use it.As DHCP the dnsmasq can give all the machines on your lan their IP, gateway IP, DNS IP, and more. I... [by jlehtone]

Dnsmasq and dhcpclient problem 3 years 30 weeks ago

Server Terminal: Fedora 11 Client Terminal: Opensuse 11.1

I had Dnsmasq server running for a while now and only thing I changed since on the DNS/DHCP server is running fwbuilder script at startup in init. The fwbuilder script is still the same script I have been using since setting up Dnsmasq. The client terminal is having trouble reaching the outside world.
