Hey Russell,
  The drop stats are generated by libpcap, so if there are
problems, especially in the libpcap, the report could be
unreliable.

   How are you determining that there is a problem?

Subject: argus and snort ?


Hi All,
	I have just noticed that one of my argus recorders seems to be 
missing packets, the irony is that the one loosing data is a 500MHz 
machine and the other is 166MHz.

When I kill the argus suspect argus process it reports:

263828758 packets recv'd by filter
0 packets dropped by kernel

I have recently started running snort on the same machine (a FreeBSD 
4.1 box) and I am wondering if there is some interaction that means 
that argus is not getting some of the packets.

Any ideas?

Cheers, Russell.
