Re: Is accounting supported?
May be you could use conntrack events subsystem for accounting? In such way, by using conntrack, it can become an a good solution to control traffic. There is a simple scrypt on python, that catch events from conntrack using ctypes to interact with libnetfilter_conntrack.so, http://code.activestate.com/recipes/577011/. 2010/1/19 Dan Williams d...@redhat.com: On Sun, 2010-01-17 at 17:15 +0100, Daniel Wagner wrote: Hi Dan, Just out of curiosity: where does the accounting information come from?

What about using SNMP data to gather accounting on interfaces? ___ NetworkManager-list mailing list NetworkManager-list@gnome.org http://mail.gnome.org/mailman/listinfo/networkmanager-list

Honestly I'd rather just go to the source (netlink) from which most of these interfaces get their data anyway. Fewer layers in the system that way. Any of the other methods get their data out of the kernel's netdevice, which is where the netlink bits read it from too.

The kernel interface to netfilter is netlink based and the ulogd daemon uses this API. Though I'm not so sure if the authors recommand to use this API. IRC the iptables API should not be used directly. I looked into that a few weeks ago and you get netlink messages with the statistics details for all network interfaces. You get them even when you unplug the adapter suddenly via the DELLINK netlink message. However you don't get periodic updates. It might be useful to extend the kernel with an option to send NEWLINK updates when certain amount of packets/bytes have been received or transmitted. The tricky part here is obvious the case that if you have no consumer of these information you don't want any updates. Meaning if no UI component is showing these information, then don't even bother to make the kernel send out updates.
