I have reported the issue as a new bug because all the other where bugs ( #604273, #634880, #636597, #651079, #674186) referring to a different package version

[Stefano Lenzi (kismet-sl)]

The problem in the installation phase of the package is caused by the following part of the dnsproxy.postinst script

if [ -x "/etc/init.d/dnsproxy" ]; then
        update-rc.d dnsproxy defaults >/dev/null
        if [ -x "`which invoke-rc.d 2>/dev/null`" ]; then
                invoke-rc.d dnsproxy start || exit $?
        else
                /etc/init.d/dnsproxy start || exit $?
        fi
fi

which try to start the dnsproxy deamon. Unfortunatly the default configuration that comes with the dnsproxy is not generic. In fact, the package file
/etc/dnsproxy.conf
contains the following line
listen 192.168.168.1
which avoid the starting of the deamon if the host has different IP address.

I believe that the dnsproxy.postinst script should not start the deamon but it should provide a message such as "Please configure the dnsproxy to tailor your need and then start it with the sudo /etc/init.d/dnsproxy start"

[Stefano Lenzi (kismet-sl)]

The patch above is not agains the installation script, because by browsing the bzr maverik branch I figured out that the buggy part of the postinst script is generated automatically by the DEBHELPER "toolchain" so I decided to modify the default network configuration of dnsproxy to be more generic

A better solution would be the modification of the configuratin uppon the actual configuration of the host (but it could be too risky)

Please change it to fix released if you think that is valid
