 Yes it does, on my HP 8630w too. Which gives me acpiec(4) back.
 Which fixes acpibat(4) and acpiac(4). Which fixes apmd(8), who
 correctly reports the battery/AC status now and dims/brightens
 the screen accordingly, too.

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.

Is anyone experiencing the same? Is there any point
upgrading to a 4.7-beta snapshot in this regard?

Hello misc,

Would the following filter work?

match to $my_upstream_1 source-as {some_as} set prepend-self 4

I would like to prepend my as to make as path longer for some_as
trough my_upstream_1 and make it to prefer path trough my_upstream_2.
It does not produce error with bgpd-n but there is no effect as well.


Are you certain it has no effect (and how?) - you can't rely on
AS path prepending to change how traffic flows, if someone gives you
a higher localpref they'll use that path irrespective of the path length.



Hi Stuart,
I am certain as I don't see my prepend on some_as looking glass.

The actual filter looks like this without the comment:

match to $spnet_bg #(AS8717) sourse_as 9070 set prepend-seff 4

and this is what I see on 9070 looking glass:

inet.0: 5185 destinations, 8315 routes (5184 active, 0 holddown, 1 hidden)
+ = Active Route, - = Last Active, * = Both

A DestinationP Prf   Metric 1   Metric 2  Next hopAS path

20682 I


{master:0}

where 20682 is my as.

Filter like:

match to $spnet_gl prefix {$net3 $net4 $net5 $net6} set prepend-self 2

works perfect but it prepends all as paths from this neighbor and it 
changes the routes to me.


I am aware of local preference.

Thanks for the help,

I had the same doubt some time ago, but you are right, these are the
temperature limits.

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

 and others are confused).

I had, with my previous HP nw9440 notebook, the same problem with
those sensors, but not always.
And more often when the machine was first started, almost never on
reboots. I think there is something inside that needs to settle down
before the readings make sense. I saw -2000 degrees on one of them,
one time. :-)

If I waited a few minutes (sometime even a few seconds), pausing in
rc.securelevel at the softraid password prompt I scripted, the problem
solved itself.

You could try putting some sleep xxx inside rc.securelevel and see if
the messages continue to pop up on the console or stop. The system
does not shut itself down until the boot is over.

HTH.

Strange problem | routing issue

2010-02-11 Thread Shailesh Tyagi 
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 nicely.

And like that we have around 8 customers all going thru vlan trunk configured
between bgpd server and cisco switch.
---The Problem-
As soon as we start traffic bgp server starts behaving strangely. for example
if we ping any IP, customer side or towards upstream from the bgpd server,
first few seconds we get no route to host and after few seconds it starts
getting the response. When we try to ping the same IP again, behavior remain
unchanged. which means it can't get the route for few seconds. We have checked
the media connections and under normal conditions (without bgpd and vlans)
everything works fine. I am not sure if its related to so many vlans, bgpd
configuration or bug in routing daemon. Another strange thing I have noticed
is that it shows 10M memory in TOP command where server has 8GB RAM. I am
pasting the dmesg and other logs for your info.

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 filtering.  The newer, ie more expensive Juniper

SRX firewalls supposedly can do it.  They are based on Juniper

Hello there,
I came across a cheap USB flash drive, particularly a SanDisk Cruzer U3:

Reading and writing from/to a raw disk /dev/rsd1c gives same exact

1600+0 records in

1600+0 records in
1600+0 records out
209715200 bytes transferred in 19.253 secs (10892315 bytes/sec)

Which are reasonable numbers.
Now let's put a filesystem on it:

As you can see here, 800KB/s is quite low, compared to raw read rate.
What can be the cause? I don't know, but let's try formatting sd1a with
frag-size of 8192 and block-size of 65536

(same exact sequence of steps as above, just adjust frag-size and
block-size)

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.

for the OP, I think it has a fair chance to work out, given the

basically you want the fastest single core possible (you'll get a

memory access possible, thus an architecture with fast caches -
nehalem should beat core2 there, but i haven't tried yet. you want to
run i386 instead of amd64 (this needs a re-check really, it's been long
that we did that and amd64 changed a lot). good nics help a lot, but i
dunno which 10G ones to use. bus bandwidth/latency etc should not make
a difference here on any quite recent not crap hardware you can buy,
disk i/o is irrelevant. you will need a very very very fast opengl

Re: routing and pf at 10Gbps

2010-02-11 Thread Joel Wiramu Pauling 
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 be
involved in these, as Diana says they will have FPGA's under a
freeOS... i.e JunOS is essentially 4.4 BSD with a bunch of Juniper
FPGA drivers.

 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
 filtering. B The newer, ie more expensive Juniper
 SRX firewalls supposedly can do it. B They are based on Juniper

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.

That's why you see very few servers with video cards.  Even
well-designed cards can rob the system of precious, precious I/O.
Same goes for sound cards (which, from what I've heard, used to create
havoc by not lowering its IRQ after each request), floppy drives,
anything not needed for the system to function basically.

 the

 etc.)
 
 
 
 That's why you see very few servers with video cards.  Even
 well-designed cards can rob the system of precious, precious I/O.
 Same goes for sound cards (which, from what I've heard, used to
 create
 havoc by not lowering its IRQ after each request), floppy drives,
 anything not needed for the system to function basically.

They might not have physical add-in cards, but all i386/amd64 servers 
have graphics hardware attached to some interconnect bus. Otherwise 
they would not be able to paste those Microsoft Windows stickers. And 
on many the only way to turn off the on-board (often inferior) graphics 
hardware is to insert an add-in card...

 Hey all,
 
 I was hoping there are some heavy PF users here, who wouldn't mind sharing 
 some of their experiences?
 So I've watched Hennings talk about PF performance, read the PDF, but I 
 haven't actually seen anyone saying they can, and do, PF at 10Gbps.
 Can it?
 If so, what actual hardware can? Or more precisely, what hardware could 
 sustain our expected usage?
 
 
 We've got a big project in it's earliest stages which would require very 
 basic 
 firewalling at multi-gigabit-per-second. Probably in the region of 3Gbps (yes 
 yes, PPS is the real killer), with peaks for software releases much higher.
 No NAT, just routing (bgpd/ospfd), and simple limits on what ports are 
 available. I can't imagine needing more than 200-300 rules.
 I'm actually a Linux guy, and I'm pretty confident that netfilter simply 
 won't 
 keep up, and while we've not personally used OpenBSD in anger yet, there is 
 plenty of time to get acquainted.
 
 So, at the edges I'm imagining a large hardware router, handing off to 
 OpenBSD 
 to sub-route, VLAN, PF, to the actual servers, and then a few 10s of Mbps of 
 IPSec stuff back to base.
 The traffic patterns expected are very approximately:
 5Mbps DNS
 30Mbps of HTTP requests that elicit a sub-500byte response. 200,000,000 hits 
 per day.
 300Mbps of normal HTTP.
 2-3Gbps of several hundred KB, to many-MB, files over HTTP.
 20Mbps of stuff over IPSec. syslog, ssh, snmp, etc.
 
 Nearer the core will have much more complex PF rules, but only on a few 
 hundred Mbps, so easy for modest hardware.

Performance, cheapness, quality. You should choose only two of these.

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.

Software releases built on or after January 28, 2009 have already fixed the 
issue.

Every OS can have it's vulnerabilities. OpenBSD is very secure, but I'm sure
it cannot route (even without pf) 10Gbit/s traffic.
