[[category:system files]]This is a sample of [[dnsmasq.conf]], mainly included because of all the comments. I'm stripping all the comments out of my actual file so I can see which lines are actually in use. This is a fairly basic configuration which uses [[/etc/hosts]] as well as having additional local-machinename definitions in a file called /etc/dnsmasqhosts.

Overview

This is a sample of dnsmasq.conf, mainly included because of all the comments. I'm stripping all the comments out of my actual file so I can see which lines are actually in use. This is a fairly basic configuration which uses /etc/hosts as well as having additional local-machinename definitions in a file called /etc/dnsmasqhosts.

# Set the DHCP server to authoritative mode. In this mode it will barge in
# and take over the lease for any client which broadcasts on the network,
# whether it has a record of the lease or not. This avoids long timeouts
# when a machine wakes up on a new network. DO NOT enable this if there's
# the slighest chance that you might end up accidentally configuring a DHCP
# server for your campus/company accidentally. The ISC server uses the same
# the same option, and this URL provides more information:

# Normally responses which come form /etc/hosts and the DHCP lease
# file have Time-To-Live set as zero, which conventionally means
# do not cache further. If you are happy to trade lower load on the
# server for potentially stale date, you can set a time-to-live (in
# seconds) here.

# If you want dnsmasq to detect attempts by Verisign to send queries

# If you want to fix up DNS results from upstream servers, use the

# and this maps 1.2.3.x to 5.6.7.x

# Change the following lines if you want dnsmasq to serve SRV
