Go2Linux | Linux Operating System

First a small introduction about wicd for those who are not familiar with it, it is a deamon/client application that manage your networks connections, more or less like Networkmanager which is the default in Ubuntu, I was using wifi-radar untill I discovered wicd reading the ArchLinux wiki, well now lets go to the problem I got while running it on Debian and how I solve it.

I have installed wicd to manage my network connections on my Debian Squeeze, the daemon started OK, but when I was trying to start the client I got this error.

Loading...
Attempting to connect tray to daemon...
Success.

The solution was pretty easy, but it was hard to find on google, that is why I want to put it here.

This is the content of my /etc/dbus-1/system.d/wicd.conf

< busconfig >
        < policy user="root" >
                < allow own="org.wicd.daemon"/ >
                < allow send_destination="org.wicd.daemon"/ >
                < allow send_interface="org.wicd.daemon"/ >
        < /policy >
        < policy at_console="true" >
                < deny own="org.wicd.daemon"/ >
                < allow send_destination="org.wicd.daemon"/ >
                < allow send_interface="org.wicd.daemon"/ >
        < /policy >
< !--
        < policy context="default" >
                < deny own="org.wicd.daemon"/ >
                < allow send_destination="org.wicd.daemon"/ >
                < allow send_interface="org.wicd.daemon"/ >
        < /policy >
-- >

        < !-- If you would like to restrict usage of the wicd daemon to some
             subset of users, then you can do something like this after
             commenting the above  block
        -- >
        < policy group="netdev" >
                < deny own="org.wicd.daemon"/ >
                < allow send_destination="org.wicd.daemon"/ >
                < allow send_interface="org.wicd.daemon"/ >
        < /policy >
< /busconfig >

As you can see in the last block it is restricting the use of wicd to the netdev group, so I only had to add my user to that group and it start working, to do that run:

usermod -a -G netdev youruser
