Hi List,

I am using Network manager with Gnome network applet on Fedora 12.

Are there any options for getting accounting like information about connect
times, data bytes in and out etc?

Not yet, but I've been trying to get somebody interested in doing the
feature since I'm swamped with a bunch of other stuff at this point.  It
shouldn't be too bad; we just keep a sqlite database around of all
connection start/stop/bytecounts and then expose that as a D-Bus
interface that applets can read.  Either somebody needs to step up or I
guess just wait until I get around to it.

I'd like to volunteer to do this. I'll get around to it over the weekend
and send you patches if you like. All I need is a list of desired
features and I'll implement it. Just my way of contributing to NM!

Excellent!  I put a summary of what I think should be done here:

Does the stuff in Comment #3 sound doable?  You don't have to do
everything at the start but we can do it incrementally.  Like you don't
need to populate the "user-id" and "user-name" fields yet, since we need
to do a bit more internally to NM to store that information in the
NMActRequest structure (by pulling the uid off the D-Bus request to
start the connection).

Let me know if you have any questions.

Just out of curiosity: where does the accounting information come from? I see one possible solution using netfilter with ULOG target and the ulogd daemon.

I guess when using ulogd there is always a certain lag between the number of bytes transferred/received and the user defined maximum of bytes transferred/received (probably enforced by PolicyKit). I don't think that's a real problem and could be workaround if there isn't the need to have exact numbers.
