The ppp daemon could do this if it knew the associated link and could retrieve the MAC address associated with it. there are several roadblocks.. 1/the ppp daemon doesn't keep a control socket associated with the connection so it can't inquire about the MAC address. 2/ If it were to try create a new control socket, it could not connect it to the existing data socket. It may be possible that the ppp daemon might know the netgraph node name for the data socket node, in which case it could get the information requested. This would require an answer from Brian > 2.

I think you need to leave it to ppp. but maybe ppp can become aware of teh MAc address. > > Result: A log file produced with a session match of: > > MAC add - IP add - username - time of session. > > Should I touch the ng_pppoe code? or should I create a netgraph node to > place between ng_node and ng_ppp? > Am I on the good way Probably not good to touch the pppoe code.. until you discuss it with Brian.
