HTH! After doing the above, the daemon of "NetworkManager" can be activated. That is the good news. However, the nm-applet icon just disppeared after reboot. I am sure that notification area is enabled because the three short lines just having appeared to the left to the nm-applet icon remained there. What can I do next? Or what additional information should I provide to you? -- http://isp.url.com.tw 智邦生活館免費撥接上網 電話 40661234 / 4497890 帳號 url 密碼 url___ networkmanager-list mailing list networkmanager-list@gnome.org http://mail.gnome.org/mailman/listinfo/networkmanager-list

I'd actually advise that you undo the changes you made, because: 1) The file already contains all the security exceptions that are needed, the additional exceptions you added are not necessary (and are actually risky). 2) While a '#' does indeed denote a "remark" in many file formats, this does not apply to DBus config files. These files are XML files, and XML comments take the following form: Thus, the "remarks" you added are invalid syntax, and so dbus won't load the file. This definitely will cause problems. I think Dan William's suggestion should do it for you; I've recently run into the same bug myself, and I've also found that forcing dbus to reload its config files is a workaround. So, in summary: -) Undo the edits to /etc/dbus-1/NetworkManager.conf -) run sudo reload dbus -) run sudo start network-manager And you should be set. HTH!

For a while there's been a bug in D-Bus itself (since fixed) that if you wrote or updated a permissions file in /etc/dbus-1/system.d, the bus would sometimes fail to completely re-read that permissions file. If you run into this problem, you can sometimes: killall -HUP dbus-daemon and then stuff will work. If that doesn't work, then the D-Bus permissions listed in the file may not be correct for your distro.

Yep, that certainly would cause problems, and it's not altogether surprising that this would happen. The DBus system daemon has a very strong security policy, and daemons like NetworkManager need to setup specific security exceptions in order to work. Normally, this is something that distributions take care of, but here it seems to have broken somehow. More specifcally, NetworkManager needs to be able to claim the bus name "org.freedesktop.NetworkManager" on the DBus system bus. By default, no application is allowed to claim any bus names, so we need to configure DBus to allow N-M to claim that name. On Ubuntu, the file /etc/dbus-1/system.d/NetworkManager.conf is supposed to take care of that. What does that file contain on your system? > I opened a terminal and run 'sudo start network-manager', which showed > OK.

If NetworkManager is unable to obtain its characteristic bus name, it quits. The only way to use NetworkManager is over DBus, so it really needs to have those security exceptions in place in order to work at all. HTH!
