http://www.linuxquestions.org – Published at LXer: 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 available in most Linux distributions. Read More... (HowTos)

Hello.

I am running my ubuntu sever for over 2 years - Ubuntu 12.04.1 LTS (GNU/Linux 3.2.0-32-generic x86_64) as today.

I am using dnsmasq as DHCP server and DNS forwarder.

Today dnsmasq unexpectedly stopped resolving hostnames.

ps aux|grep dnsmasq

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.

[ubuntu] dnsmasq help plz 41 weeks 6 hours ago

Every time I start dnsmasq I get this

Starting DNS forwarder and DHCP server: dnsmasq dnsmasq: no interface with address 10.8.0.1 failed!

and if I start openvpn my vps shuts down were I can not connect to it at all via ssh I have to reset it all using the website I followed this guild http://library.linode.com/networking...bian-6-squeeze I've done everything there but yet ran into this problem.

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'm running Scientific Linux 6.3 and just updated the machine to dnsmasq-2.48-13.el6.x86_64. The machine is on local ip 192.168.1.100. I have a local caching DNS setup that was working until the update.

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.

This might be the right forum, or not.

Old stock DNS (nslookup, dig, ssh) etc would attempt to use each of the domains listed in the search list (/etc/resolv.conf) to find a given target given a base_name (w/out a ".")

The current configuration uses 127.0.0.1 as a caching server and relies on dnsmasq to lookup dns entries from upstream providers. DNSmasq as driven by NetworkManag

I've had dnsmasq installed for years to cache DNS requests.
