digitemp/usb
Hi has someone used digitemp with usb adapter on openbsd ? i currently test digitemp 3.5.0 on 4.0-stable with a ds9490R usb adapter and it segfault like this $ ./digitemp_DS2490 -s /dev/ttyU1 -w DigiTemp v3.5.0 Copyright 1996-2007 by Brian C. Lane GNU Public License v2.0 - http://www.digitemp.com Found DS2490 device #1 at /dev/usb0//dev/ugen0 Segmentation fault (core dumped) thanks a lot Regards Julien note: - used with libusb-0.1.10ap1 - no return on dt-general@

Re: OpenBSD on Xeon 64 bit
Alvaro wrote: Hi, I like to know if the OpenBSD for amd64 is working fine with intel Xeon processors (64 bit). I am reading here ( http://en.wikipedia.org/wiki/AMD64 ) and here ( http://en.wikipedia.org/wiki/Xeon#Xeon_.26_Xeon_MP_.2864-bit.29 ) that these processors are based on AMD64 instruction set. The openBSD faq for AMD64 said: All versions of the AMD Athlon 64 processors and their clones are supported. I assume that their clones are the processors based on AMD64 instruction set...like this xeon. Am i wrong? Right now they are working very well with the OpenBSD i386 release. They will probably work just fine with amd64, then, assuming you have the newer versions which clone the amd64 instruction sets moderately well, as opposed to the older ones that didn't. That's the general answer based on a general question. To know how it works in YOUR case, you would have to provide exact details of your machine and hope someone recognizes it as exactly one that they have in service as you are planning on using yours, and that you don't get mislead by people who THINK their machine is just like yours, but is very different in subtle but critical ways... .. OR, since you already have the machine, try it out! Nothing beats working fine tests done on your own hardware on your own application. Nick.
Re: Dummy Interface In OpenBGPd
On 2007/02/07 13:36, Claudio Jeker wrote:
Btw. for ospfd you can use interface lo1 to reliably redistribute the
loopback address.
I have configured a router with yyy.yy.yyy.247/32 on lo1 and yyy.yy.yyy.247/28
on vlan2244. This seems attractive since BGP sessions can be bound to an address
which is available (at least over one of my metro links) whether or not OSPF
is running - (not to mention because I am working in a fairly small PI block
and would really like to avoid burning another /28 ;-)
The vlan already has a router acting as DR.
If I configure vlan2244 before lo1, all is well, associations are formed,
prefixes are seen.
If I configure lo1 before vlan2244 (default order for /etc/netstart), ospfd
doesn't act on any packets coming from the DR, it believes that it should be
DR itself, but no outbound packets are seen by tcpdump -i vlan2244 (or -i lo1).
I can work-around this at startup by altering netstart as follows,
but I wondered:-
1) is this an acceptable work-around?
2) should ospfd handle this any differently?
3) is it bloody stupid to be doing this?

kernel debug simple question
hi there, i am trying to troubleshoot a usb external disk. the disk detaches while mounted and used. how can i umount / before i am going to reboot? syncing cannot work in this case of course, but that leaves only the external disk in a dirty state, not my /, hence the question. is it possible to do it before getting dropped into ddb? or is it possible to do it from ddb? some posts past implied that anything is possible from ddb :D -f -- why is the alphabet in that order? is it because of that song?
Re: pcn in VMware, 5KB/s
Brad Brad wrote: Scp's between the guest and host only manage about 5KB/s so I tried going back to le which worked great. I configured a new kernel with disable pcn* but on next boot I had no nics at all, so i tried again disable pci* also since I think le is isa, but it still didn't work. That's strange that pcn is giving you worse performance than le. I've had performance problems under VMware (ESX 2.x) where the host's NIC is hard-set speed and duplex, and the guest winds up with a ton of collisions, and setting the duplex in the guest doesn't make a difference. Maybe that's the case here? You could always try using vmxnet/vic.
Re: external usb disk freezing machine (not always)
hi there, some more updates.. feels a bit like talking to myself :} i have compiled a custom kernel with options UMASSDEBUG, UHUBDEBUG. there is a log attached to this mail showing as the disk is attached to the first usb (high speed) port (@17:27:36) and then to the second (high speed) port (@17:29:07). at the end of this session, my usb mouse stopped working also and i had to reinsert it into a high speed port. furthermore, i have found out, that the disk works flawlessly *if* plugged into the usb1 port and misbehaves in the high speed usb2 port: amaaq usbdevs -v Controller /dev/usb0: addr 1: full speed, self powered, config 1, UHCI root hub(0x), Intel(0x8086), rev 1.00 port 1 powered port 2 powered Controller /dev/usb1: addr 1: full speed, self powered, config 1, UHCI root hub(0x), Intel(0x8086), rev 1.00 port 1 addr 3: full speed, self powered, config 1, External HDD(0x0900), Western Digital(0x1058), rev 0.00 ^^ port 2 addr 2: low speed, power 100 mA, config 1, NetScroll+ Traveler(0x002e), KYE(0x0458), rev 0.00 Controller /dev/usb2: addr 1: full speed, self powered, config 1, UHCI root hub(0x), Intel(0x8086), rev 1.00 port 1 powered port 2 powered Controller /dev/usb3: addr 1: high speed, self powered, config 1, EHCI root hub(0x), Intel(0x8086), rev 1.00 port 1 powered port 2 powered port 3 powered port 4 powered port 5 powered port 6 powered this session is still alive and well after more than an hour, while if in an usb2 port, in a matter of a couple of minutes, or sometimes instantly, it detaches. for watching movies it is kind of enough i guess :D i am wondering, maybe a quirk is needed for this drive? if yes, how does one go about finding what and where? it's older brother, a 200G model (also WD) worked fine before, but i have sold it, and can't test it anymore... one more thing i have noticed, gkrellm actually shows read/write stats when the disk is in usb1 and shows nothing when in usb2 port, unless the disk was present at boot time... also, usbdevs(8) blanks these stats for a couple of seconds (shows only 0) but then resumes later. i am starting to run out of ideas, so any help is welcome...

malloc guard page question
Hi everyone,
Recently I have been going over a bunch of the documents in
openbsd.org/papers in order to write an overview of the security
features in OpenBSD for school.
I have a small question concerning the malloc G option.
Theo basically says this in slide:
(http://www.openbsd.org/papers/ven05-deraadt/mgp00028.html)
-
[...SNIP...]
malloc.conf 'G' option:
[...SNIP...]
Cannot enabled by default yet. Maybe never, but we will see.
---
This was written in 2005 (2 years ago). I installed 4.0 and read
through the man page of malloc, and I didn't find any indication that
the G option is enabled by default yet (couldn't find the answer on
google either).
My question is the following: Is there any plans to enable the guard
page feature of malloc ('G' option) in the future? Is so any
timetable?
Thank you for your time,
Jd

I finally got it to work.
I installed syweb for the symon.
There is a script called install_rrdtool.sh which installs the necessary
libs for rrdtool to work in a chroot environment.
I launched that script and it most probably copied a library I missed out.
Unfortunately I have no clue which ones where missing.
The ones on your list are not in mine because they aren't on my system at
all.
Here is the script source:

#!/bin/sh

Re: malloc guard page question
I was hoping re-re-re-reading Theo's slide would help me understand, but unfortunately it only raised another question to which I can't find an answer: On slide 27 (http://www.openbsd.org/papers/ven05-deraadt/mgp00027.html) it says: If you try to read/write beyond the end of an object, maybe there is a guard page there? So is there a guard page or not? :) If the G option of malloc is used I'm under the impression that every object will be surrounded by guard pages. But if the G option is not used, will there be any guard pages at all? If so how are they allocated? Thanks, -Jd
Broadcom Gigabit NIC Interface Translation From Debian/Linux To OpenBSD
Anybody, I have two OpenBSD machines connected with 2Mbps thru a leased-lines in different locations, A B. Both machines colocated at location A and location B has a bge0 NIC card with 100/1000Mbps speed and each of these interfaces shall be connected to a device between the sites. This NIC card is detected and configured in Debian/Linux as: eth1 speed 10 duplex full autoneg off I just wonder how I should re-configure this NIC card in OpenBSD. I tried Location A -- $sudo vi /etc/hostname.bge0 inet 192.168.111.1 netmask 255.255.255.0 NONE Location B -- $sudo vi /etc/hostname.bge0 inet 192.168.111.2 netmask 255.255.255.0 NONE What stumbled me is that I cannot ping location A from location B vice-versa. Any tips to sort this out is equally appreciated. Regards, Demuel
