It's been an interesting two days. About a week ago, my OLPC XO arrived
in the mail; I turned it on and tried to find my wireless network.
Almost immediately my family complains there's no internet! Panic on
the OpenBSD router. Well, I had my work cut out for me because I'd
never setup serial console before. Thanks to FAQ; changes on router
were quite easy (even though it's i386 and there were lots of caveats
about maybe it won't work). Then to find a null-modem cable (I knew I
had usb/serial cable, but it took some time to find it). I could have
done it with just the null-modem cable; but that would mean I'd use a
windows system for console and I thought if I was going to do this; I'd
do it right - OpenBSD all the way. I did use a windows machine to make
sure everything was setup and hookup correctly; since I had used
hyperterm and null modems cables in another life. Then came a BIG
problem (for me). What program does one use on OpenBSD to talk on the
serial port? I figured the answer had to be out there somewhere (it was
- 'tip'); but it took me HOURS to find it. By comparison, it took only
a few minutes to learn how to modify /etc/remote to talk to usb/serial
cable on ttyU0. Then I had to wait for the people in the house to stop
using the internet...
panic is easily reproducible...
- power up the OLPC XO
- goto "neighbourhood"
- click on icon for my router.
- the OpenBSD router panics.
I'm not sure what to include, but here is ifconfig, trace, ps, dmesg.
