Actually I was hoping that if it is nothing more than sarcasm Henning
would give a hint -- I'm old enough to remember earlier generations of
i386 architecture where poorly designed graphics card would affect the
entire bus performance to slow down all kinds of I/O (disk, lan, etc.)

| Chris Cappuccio | Re: Strange problem | routing issue
It's hard to tell from the jumble of obfuscated output that you posted to the list, it sounds like you have a larger network (/24?) directly configured on a local interface, and you are expecting to reach parts of it (/30, /27, etc...) through BGP. You should better plan your network configuration so that you have no overlapping subnets on any of your router interfaces.

Hello,
We are facing a strange problem while trying to use openbgpd. We would like to
use openbgpd as our core BGP router on a Dell Poweredge R210 server with quad
core xeon/ 8 GB RAM/ 6 x1GB ports (2 on board Broadcom and quad port Intel
adapter). 4.6 stable installation failed because it could not detect hard disk
(I guess its related to the controller). Then we installed current 4.7
amd64(10 Feb build) which detected the HDD and installed properly. After
configuring BGPD everything camp up ...

Henning, I told you, we should not talk about unfinsihed projects.
We planned to announce this in exactly 7 weeks. Anyway, to late, the cat
is out of the bag.
So Henning and Oga are working at offloading pf into the graphic card
cores by using the DRI interface. The shader will evaluate the ruleset
and packets in parallel and use the graphic memory for the state table.
Additionally if the speed of one card is not enough you can use SLI or
crossfire to use multiple cards in parallel.

Thanks very much guys, much useful information.
I'll be sure to purchase servers with the fastest graphics cards possible!
We had a Juniper tech in today, and he suggested the SRX-3600. It's almost
certainly faster than any single software platform can do (~18Gbps IMIX), but
is it worth 10 times the price, and 5U of rack space? Especially for a
parallisable problem.
Junos can't come close to the scriptable service monitoring and route
manipulation that almost trivially easy on openbsd ...

| Diana Eichert | Re: routing and pf at 10Gbps
yes, people run firewalls on 10G circuits
I am not aware of anyone filtering at 10G who is using off the shelf
hardware, with open source O/S.
Large enterprises use either commercial firewalls, for example
Juniper Netscreens, or build systems using FPGA cards with locally
produced code.
Either way the filtering is done in hardware.
In my experience the Netscreen 5x00 firewalls sold with 10G cards
and MGT3 card can not do line rate 10G, though it was marketed as
capable of 10G ...

Alcatel-Lucent do a AA-ISA card plugin module for their 7750 range of
routers. Which enables you to do filtering at 50GB (and scale it up to
800GB) per 12U router.
Having recently investigated this segment for work. Allot,
Sonicwall(which is a Linux Variant) and a few others are running FOSS
firewalls filtering appliances at 10GB+ and it's not just the router
vendors (nortel, cisco, junper,alcatel) that do that sort of speed
these days. I can't comment on the hardware blobs that may also ...

I know of some.
I don't remember specifics, dunno wether anybody does linerate and
with what kind of packet characteristics.
for the OP, I think it has a fair chance to work out, given the
hardware is picked right. there might be some experiments needed.
basically you want the fastest single core possible (you'll get a
multicore CPU and let the others idle), and, most importantly, fastest
memory access possible, thus an architecture with fast caches -
nehalem should beat core2 there, but i ...

Sorry. These messages are always there and probably describe

What it actually says on boot is
acpitz2: Critical temperature, shutting down.
I don't think there's anything hotter than 112C while the machine boots.
With acpiec disabled, the above does not happen and sysctl hw.sensors
reports reasonable temperatures; the systme runs fine (except acpibat

It worked for a while, but recently, having acpiec enabled
(with the patch above) results in
acpitz0 at acpi0: critical temperature 115 degC
acpitz1 at acpi0: critical temperature 105 degC
acpitz2 at acpi0: critical temperature 112 degC
acpitz3 at acpi0: critical temperature 112 degC
acpitz4 at acpi0: critical temperature 90 degC
acpitz5 at acpi0: critical temperature 112 degC
at boot and the system shuts down (correctly).
So I had to disable even the patched acpiec again.
