Hello,
is there a mean to get a running process running on
a certain cpu (core)? Or restrict it from running on a cpu?
I have a cheap Atom CPU with four cores, and all interrupts,
also network traffic, is using CPU0.
Thus I would like, bgpd does not use CPU0 at all, in order
to avoid, havy cpu
Hello,
I have a router (Host B in following picture) running with OpenBSD 4.7.
One phyiscal interface is bridged to a VLAN:

Hello,
I tried:
route add -inet6 2a00:1ff8:101::/48 2a00:1ff8:102:ac01::1
and got:
route: 2a00:1ff8:101::/48: bad value
I do not understand, what is wrong with that net?
Can anyone give me a hint?
Roger.
Hello,
I've just changed a mainboard, because the old caused
problems.
The machine is acting as router, and with the old board,
CPU was charged about 30% with interrupt processing.
Now with the new board, I have a strange load:
29 processes: 28 idle, 1 on processor
CPU0 states: 0.0% user,
Hello Robert,
I did not assume a bug or similar. Just wanted to know
about IRQ balancing.
Your email does answer my question about IRQ balancing. Thank you!
Your hint about dmesg does however encourage me to post another
mail, asking about my hardware.
Roger.

Hello,
I'm operating a router using a 4 port D-Link ethernet
card with sundance chipset.
Since the machine is not doing much work besides shuffling
IP-packets from one NIC to onother, an Atom processor used
to be sufficent. System was OpenBSD-4.6, and CPU load by
interrupts was approx 30%, idle
Hi,
we've been running a BGP router on OpenBSD for
the months without problems.
Now it crashed two times within 4 days. After the
second crash, I could have a look on the screen:

Hi,
I just downloaded netio-1.26.
In the Makefile, there are the targets linux, unix, freebsd
and others, but no openbsd.
I first tried make freebsd, but received errors about
a missing libthread.
Then I tried make unix, got some warnings, but got a
binary.
However, the binary is not working
Hello,
I did not yet understand very well, how the NIC drivers are
selected. Is it done while installing OpenBSD or is it
done at boot?
In the latter case, I assume, I can replace a PCI network
interface without changing any driver settings.
If the logical interface name will be different, I

Hello,
we are operating a BGP router using OpenBSD 4.5 since
some weeks. Till today everthing went fine.
Today, the system crashed, causing an uptime much too short
for an IP router.
Can someone guess the cause from the console output?
Can we improve the kernel stability by any settings?

Hi,
top show a CPU usage of 50% for interrupts, when
my router forwards 1.5 Mbit/s of IP traffic.
My router is using OpenBSD 4.5, and running with
a VIA Eden Processor 1000MHz, which should imho be
able to handle that amount of IP traffic as router.
dmesg tells, that ACPI is not configured.
Hi,
I'm using OpenBSD 4.5 on a machine with several ethernet interfaces.
Since I have to share some cables with other users, two of the
ethernet interfaces use VLANs. The VLAN-Ids are fixed (by the
network operators leasing the cables and lines).
Since two of those VLANs should build one net,

Put log into your rules:
For example, rather than 'block in' use 'block in log', etc.
Then view the pflog interface to find the offending rule:

I already tried this, but I couldn't find those packets in the log.

Hi,
an explicite pass rule with the no state option solved the
problem.
Imho this makes sense, because a router connecting two (or
