using DBus between hosts

[Sergey Struzh]

Hi Havoc!

Thank you for your fast reply!

I've been trying to work with 1.1.2 but the results are pretty much the
same, except that connecting client exits with the weird "Family none"
printing appears for every error to occur.

Here's conf file I am using to run the daemon-dbus:


<!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>session</type>

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

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

  <!-- Write a pid file -->
  <pidfile>/tmp/dbus/sergey-pid</pidfile>

  <!-- Only allow socket-credentials-based authentication -->
  <auth>ANONYMOUS</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> -->
  <listen>tcp:host=0.0.0.0,port=6666</listen>

  <policy context="default">
    <!-- Deny everything then punch holes -->
    <allow send_interface="*"/>
    <allow receive_interface="*"/>

  <allow 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"/>
  </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>


 What am I doing wrong?
