Hi @misc,
I have a Beagleboard-xM with Ansgtrom Linux and a PC running OpenBSD 4.8, AMD64
version. My PC is connected via TP-Link wifi to household router (my otus0
internet address for this connection is 192.168.1.101). The beagleboard is
connected to the PC via ethernet.
On the Beagle I configured the ethernet device (which shows up as usb0 on
Angstrom):
# ifconfig usb0 inet 192.168.10.10 netmask 255.255.255.0
# route add default gw 192.168.10.12 netmask 255.255.255.0 dev usb0
Also, in /etc/resolv.conf I added nameservers 203.12.160.35 & 203.12.160.36
On the OpenBSD PC I created a bridge:
# ifconfig nfe0 inet 192.168.10.12 netmask 255.255.255.0
# ifconfig bridge0 create
In /etc/hostname.nfe0 is the single word: up
In /etc/hostname.otus0 is the single word: up
In /etc/bridgename.bridge0 is: add nfe0 add otus0 up
In /etc/sysctl.conf I uncommented: net.inet.ip.forwarding=1
I have also tried uncommenting net.inet6.ip6.mforwarding=1 but it did not help.
I can ping 192.168.10.12 from the Beagle, and 192.168.10.10 from the PC, but I
cannot ping 192.168.1.101 (the PC's wifi connection from the Beagle, "network
is unreachable").
The first time I set this up (a few days ago), I could ping the outside world
from the Beagle running Angstrom. I loaded Ubuntu onto the Beagle tried the
setup again, and could not reach the outside internet. Now I've gone back to
Angstrom and cannot get the connection to come back up. I am not sure why it
worked before and not now but it seems like my OpenBSD bridge0 is not working.
When it was working, typing ifconfig (as below) I seem to remember the output
for bridge0 was longer than it is now, but am not sure. Probably it is some
simple forgotten command but I do not know what it could be.
Thanks for any help!
Brett.
