Devil in the details.

Was trying to get a list of systems up on the network. Pingall.sh would not work at all. It was driving me nuts. So I went to another system and it worked.

$ cat pingall.sh
a=""
for i in {1..254}
do
ping 192.168.1.$i -c1 -w1 -v | grep "icmp_seq=1"
done

$ ./pingall.sh
64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=0.623 ms
64 bytes from 192.168.1.32: icmp_seq=1 ttl=64 time=0.113 ms

NUMA, Linus and the Ancient Conundrum

Non Uniform Memory Architecture is kind of a dry subject for most. Where a bit of code or data sits in processor cache is of little importance to the average user, unless you become interested in things like virtualization (which seeks to maximize the utilization of that cache and slams face first into the issue ) or you're interested in performance testing, in which case squeezing every extra productive cycle out of the hardware becomes a pressing concern. I happen to be interested in both, so...

I love this place.

First, you aren't **EVER** supposed to skip versions when you upgrade OpenBSD. If you have an OpenBSD 5.5 machine and you want to upgrade to OpenBSD-5.7, you need to upgrade to 5.6 first, then upgrade again to 5.7 (or backup everything, perform...
