-----Original Message----- From: owner-freebsd-questions@FreeBSD.ORG [mailto:owner-freebsd-questions@FreeBSD.ORG]On Behalf Of efb@cotdazr.org Sent: Wednesday, June 23, 1999 7:06 AM To: questions@FreeBSD.ORG Cc: efb@cotdazr.org Subject: /dev/bpf0, modload ? Trying to build a shadow intrusion detector on FreeBSD 2.2.8. It relies upon several pieces ( www.nswc.navy.mil/ISSEC/CID ) which are libpcap, a BPF interface, and tcpdump .. WHICH someone here prolly knows is dependent upon /dev/bpfN .. That is good for the experienced kernel savvy folk .. but I have to plead ignorance . . I remember that my F.BSD 2.0.5 did NOT as I got it support BPF .. so I will guess when I ls -l /dev/bpf0 and find a device present but try to run tcpdump (as root ) and get a tcpdump: /dev/bpf0: Device not configured message .. I will guess I need to find some knowledgebase docs on how to rebuild the kernel to include the /dev/bpfN .. NOT too obvious from /sys/...conf/GENERIC and friends ... True but if you look in /src/src/sys/i386/conf/LINT, it IS in there. pseudo-device bpfilter 4 #Berkeley packet filter ^^- That's all you need to add to the kernel config. DONT suppose I can modload what I need ? Nope... SO .. PLEASE send me to the right hacks list .. thanks /Everett/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
