Hi,

I just started using the python dbus API, but am having some difficulties, hoping someone here might be able to help me? (I did find the old thread in this list with an example script but API has changed so much that no longer works even with significant changes).

In brief:

- I can successfully configure and use an ADHOC network using (1) manual edits of host file (after disabling NetworkManager), and (2) using iwconfig.

- I can create an ADHOC with nm-applette gui but cannot connect to it.

- What I need to do is create an adhoc with dbus but the attached script which works perfectly to create a hotspot (with mode 'ap') fails with bellow syslog messages when mode is 'adhoc'

It looks like it creates the connection fine and even attempts to activate but then hits some weird authentication issue I can't debug?

Any chance someone has a working dbus API Adhoc network setup script they could share with me?
