Hello Matthew,
router# /usr/local/bin/snort -c /usr/local/etc/snort.conf -i em0 Running in IDS mode Log directory = /var/log/snort Initializing Network Interface em0 ERROR: OpenPcap() device em0 open:
> (no devices found) /dev/bpf0: Device not configured
Fatal Error, Quitting..
It seems that ur kernel jave not build with bpf support.So better enable it by following these steps; The Berkeley Packet Filter (bpf) driver needs to be enabled before running programs that utilize it. Add this to your kernel config file and build a new kernel:
pseudo-device bpfilter # Berkeley Packet FilterSecondly, after rebooting you will have to create the device node. This can be accomplished by a change to the /dev directory, followed by the execution of:
# sh MAKEDEV bpf0
Is the problem related to GigE and libpcap, or have I done something else wrong during the compile? What can be done to fix the issue?
Not relavant to libpcap.It is because,ur kernel doesnot support bpf. Cheers, Prabu.S --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).Version: 6.0.756 / Virus Database: 506 - Release Date: 9/8/2004
