Originalnachricht

Name        : dnsmasq
Product : Fedora 18
Version : 2.65
Release : 4.fc18
URL : http://www.thekelleys.org.uk/dnsmasq/
Summary : A lightweight DHCP/caching DNS server
Description :
Dnsmasq is lightweight, easy to configure DNS forwarder and DHCP server.
It is designed to provide DNS and, optionally, DHCP, to a small network.
It can serve the names of local machines which are not in the global
DNS. The DHCP server integrates with the DNS server and allows machines
with DHCP-allocated addresses to appear in the DNS with names configured
either in each host or in a central configuration file. Dnsmasq supports
static and dynamic DHCP leases and BOOTP for network booting of diskless
machines.

Update Information:

From dnsmasq's CHANGELOG:

Add code to make behaviour for TCP DNS requests that same
as for UDP requests, when a request arrives for an allowed
address, but via a banned interface. This change is only
active on Linux, since the relevant API is missing (AFAIK)
on other platforms.

- dnsmasq now answers local queries if --except-interface lo is used
(libvirt's use case).

- dnsmasq is now built with $RPM_OPT_FLAGS, $RPM_LD_FLAGS explicitly.
