Dave's questions

I'm looking for ways to monitor the Internet usage - the total amount of data transferred - of individual devices on my network. I'm using FreeBSD 9.0-RELEASE with pf for filtering and NAT. I'm not sure how to go about doing this.

I'm currently using Cacti to monitor my aggregate Internet usage, and I could hook SNMP monitors up to some of the devices, but not everything on the network can run SNMP.

How are other people with FreeBSD (or other BSDs, I suppose), monitoring individual devices on their networks?

I'd like to redirect all messages from dhcpd to their own log file, rather than having them appear in /var/log/messages.

Here is the configuration on /etc/syslog.conf:

!dhcpd
*.*                     /var/log/dhcpd.log

The messages are redirected to dhcpd.log, but they're also going to /var/log/messages.

What's the configuration to exclude them from /var/log/messages?
