DBUS refused NetworkManager connection to system_dbus_socket

[Eugéne Suter]

Hi there,

I've just finished compiling NetworkManager 0.6.4 on VectorLinux 5.8.
This is my setup:

DBUS 1.0.1
PolicyKit 0.2
HAL 0.5.8.1
Kernel 2.6.18.5
XFCE 4.4

Anyway, after installing NetworkManager, I tried to run "nm-applet" in a
terminal, to see if I got any errors. It seems to be a DBUS related problem:



# nm-applet

(nm-applet:20521): GnomeUI-WARNING **: While connecting to session manager:
Authentication Rejected, reason : None of the authentication protocols
specified are supported and host-based authentication failed.

** (nm-applet:20521): WARNING **: <WARNING>      nma_dbus_init ():
org.freedesktop.DBus.Error.NoServer raised:
 Failed to connect to socket /var/run/dbus/system_bus_socket: Connection
refused




Is it a policy related issue? This is what my /etc/dbus-1/system.conf file
looks like:




<!-- This configuration file controls the systemwide message bus.
     Add a system-local.conf and edit that rather than changing this
     file directly. -->

<!-- Note that there are any number of ways you can hose yourself
     security-wise by screwing up this file; in particular, you
     probably don't want to listen on any more addresses, add any more
     auth mechanisms, run as a different user, etc. -->

<!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-Bus Bus
Configuration 1.0//EN"
"http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd">
<busconfig>

  <!-- Our well-known bus type, do not change this -->
  <type>system</type>

  <!-- Run as special user -->
  <user>messagebus</user>

  <!-- Fork into daemon mode -->
  <fork/>

  <!-- Write a pid file -->
  <pidfile>/var/run/dbus/pid</pidfile>

  <!-- Only allow socket-credentials-based authentication -->
  <auth>EXTERNAL</auth>

  <!-- Only listen on a local socket. (abstract=/path/to/socket
       means use abstract namespace, don't really create filesystem
       file; only Linux supports this. Use path=/whatever on other
       systems.) -->
  <listen>unix:path=/var/run/dbus/system_bus_socket</listen>

  <policy context="default">
    <!-- Deny everything then punch holes -->

    <deny receive_interface="*"/>
    <deny own="*"/>
    <!-- But allow all users to connect -->
    <allow user="*"/>
    <!-- Allow anyone to talk to the message bus -->
    <!-- FIXME I think currently these allow rules are always implicit
         even if they aren't in here -->
    <allow send_destination="org.freedesktop.DBus"/>
    <allow receive_sender="org.freedesktop.DBus"/>
    <!-- valid replies are always allowed -->
    <allow send_requested_reply="true"/>
    <allow receive_requested_reply="true"/>
    <allow own="org.freedesktop.NetworkManagerInfo"/>
  </policy>

  <!-- Config files are placed here that among other things, punch
       holes in the above policy for specific services. -->
  <includedir>system.d</includedir>

  <!-- This is included last so local configuration can override what's
       in this standard file -->
  <include ignore_missing="yes">system-local.conf</include>

  <include if_selinux_enabled="yes"
selinux_root_relative="yes">contexts/dbus_contexts</include>

</busconfig>


Any help is much appreciated.

Regards,

Eugéne
