Hello,
I'm in the final stages of setting up a new wireless connection but have
been having problems getting bpf running. For some reason, even though bpf
has been compiled into a new kernel, the system won't automatically create a
bpf0 device. On boot, the system complains pcap_open_live: (no devices
found) /dev/bpf0: No such file or directory.
The ultimate goal is to have this laptop connect wirelessly to my
WPA2-protected WAP (already working fine with other boxes) using a static
IP.
I've successfully compiled in support for the Atheros-based PCMCIA card,
edited rc.conf to exclude DHCP and to use wpa_supplicant.conf, and
eventually compiled in bpf when I started receiving the pcap_open_live
messages.
I suspect bpf is needed not for DHCP which is not running, but for some of
the parameters I added to wpa_supplicant.conf, which is as follows:
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
network={
ssid=my_ssid
scan_ssid=1
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP
psk=my_ssid
}
If someone would be so kind as to explain what is calling bpf and how I can
create a bpf0 device by hand, I would be indebted.
Thanks...

Are you *sure* you've compiled in bpf? Did you reboot after recompiling?

I have two servers here at home, one is the afore mentioned gateway and the other is an Apache/MySQL/Samba server. Looking at the /dev on both I noticed that the gateway box has the bpf entries while the web server box does not. So I believe there needs to be an interface such as a firewall or DHCP which will consume the bpf in order for the /dev entry to be created. I suspect that you may have skipped over the proper creation of your wireless interface which would have created the bpf when initialized. You may consider trying to get the interface up and running with wireless connectivity without WEP/WPA first, then work on adding in the supplicant afterwards. My belief is when the network interface for the card comes up you will automagically then have the bpf entries in /dev. You may also take a look at /etc/devd.conf and /etc/defaults/pccard.conf for brain-jogging ideas. I do confess to not knowing enough about them. -Mike ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
