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?
