USB WLAN dongles
Hi, I have a thinkpad T40 running OpenBSD and live in a small, nice city close to Barcelona whose city hall offers free wifi Internet to everybody. Unfortunately they do not have a good coverage and where my building is, I don't get any signal. The card is identified by OpenBSD as ath0. I was thinking, as somebody in the thinkpad forum suggested, of an USB WLAN dongle, but one of those with an external antenna that is connected through a standard (typically: Reverse) SMA-connector. Next, get a sufficiently long, low-loss cable and a parabolic antenna (some 24 dBi gain, e.g.), mount the antenna at a point having preferably line-of-sight to the WLAN source (the public router/access point), and disable the Atheros internal miniPCI interface (or, is this perhaps even not necessary?). If your Linux will support the particular USB WLAN dongle, then you're in business... otherwise, well, you're in trouble! A few images showing what type of USB WLAN dongles I am having in mind are something like this no. 1 http://cgi.ebay.com/USB-11g-Wireless-2-4G-WiFi-WI-FI-LAN-External-Antenna_W0QQitemZ150208258653 or this no. 2 http://cgi.ebay.com/Alfa-50mW-USB-WiFi-24dBi-Grid-w-Mount-WLAN-10-ext_W0QQitemZ130190878170 or this no. 3. http://cgi.ebay.com/802-11g-Wireless-LAN-WLAN-High-Gain-USB-Adapter-Antenna_W0QQitemZ180168479250 An example of an outdoor, high-gain parabolic WLAN antenna is shown here - http://www.embeddedworks.net/antenna/f2400_Outdoor-Parabolic-Grid-Dish.html there are TONS of such available, and at a variety of prices; Google around a bit, and you will find much cheaper ones. Now, my question is... will this work with OpenBSD? Has any of you tried this? I have googled for a while and found nothing... thanks Pau

Perhaps you can mount the dongle in a parabolic dish and run USB back to your system. Standard USB cable is good for about 5 meters; If you're going farther than that, you can get powered repeater cables that are good for up to 30 meters or so, or place a small box like a soekris close to the dish, and run ethernet. Either way signal losses on a digital run will be much, much less than even the most expensive low-loss cable :-) -Ryan

If you can put the USB adapter outdoors with the antenna directly connected, that will keep loss to a minimum. If not, use as short as possible LMR200-type cable, and have the main length as a USB extension (if you need longer than USB allows, use another computer to connect to the wireless network running NAT, and connect to that by ethernet; soekris/pcengines board are useful for this). You might also want to think if you need some protection against lightning. At the very least unplug if an electrical storm is nearby... 24 dBi gain, e.g.), mount the antenna at a point having preferably Maximum power you are allowed to radiate from the antenna in Europe under ETS300/328 is 20dBm (100mW), otherwise you need a license. With a 50mW (17dBi) radio like the ones you show, you're only legally allowed to use an antenna with 3dB gain unless you have software control to reduce transmit power (or use lossy cable etc). A few images showing what type of USB WLAN dongles I am having in mind are something like this no. 1 Images of the cases don't help much. If you can't get information about the type of MAC/radio used, see if you can get a copy of the Windows driver and you'll find the vendor and device id in the inf file, you can look this up in sys/dev/pci/pcidevs and see if there's a driver which claims the device.

At least my 3Com access point can do that, and it should be possible with other devices, especially if you use DD-WRT or some other alternative firmware like that. Ethernet-connected WLAN client devices also exist specifically for the purpose of connecting ethernet-enabled devices to a WLAN. Those usually have a convenient external antenna connection, too. With PoE one of those would probably be my choice to solve the problem if I had an external antenna - if I had to hack something together I'd use a USB dongle and some kitchenware as a reflector. -- Jussi Peltola

You should just take care that for this kind of size, you will have to raise max table-entries in pf.conf. As for the CPU usage, spamd on this machine uses 10% at max of one of the CPUs (2X Intel(R) Xeon(R) CPU 5130 @ 2.00GHz), and is generally at 5% or less.

Hard Drive Errors
Hi Everyone I would like to revisit a problem I was unable to solve about a year ago, an error messages I was getting about pciide temouts. Several times we have had hard drives that will display the following error and then the computer freezes: wd1(pciide1:1:0): timeout type: ata c_bcount: 65536 c_skip: 0 pciide1:1:0: bus-master DMA error: missing interrupt, status=0x21 I tried to find the source of this problem and could not. I'm willing to accept that this could be due to a dying hard drive, overheated hard drive, or any similar causes except for a loose cable. The second error is very similar but does not make the computer lock up. I have been having this problem on many computers and more frequently than the above error. It doesn't seem to have any direct side effects. But the other day I noticed the error on one of my computers and we were having speed troubles with one of the disks. So we tried to reboot and for some reason the system got stuck and the watchdog didnt reboot the machine. I have no idea if this problem is linked to the hard drive error. Anyways, here is the error: wd2(pciide1:1:0): timeout type: ata c_bcount: 49152 c_skip: 0 pciide1:1:0: bus-master DMA error: missing interrupt, status=0x61 wd2a: device timeout reading fsbn 176823520 of 176823520-0 (wd2 bn 176823583; cn 175420 tn 3 sn 34), retrying wd2: soft error (corrected) Does anybody know what this is and if its a bad thing?

Hi Misc@, I'm currently setup bgp router using openbgp. Routes learned from openbgpd are stored in routing table 1. So, I got this client from NET2, coming from the same interface that my ibgp peer coming from, and I want to pass client from NET2 going to regional exchange to QUAGGA router. I got no luck with: pass on $ext_if from $NET2 to any modulate state rtable 1, NET2 always use the default route via $ext_if when going to regional exchange I appreciate any input and suggestion regarding this.

Re: Hard Drive Errors
Both look like a disk going bad. run a dd and read the entire contents of the disk to allow the disk to reallocate the bad sectors. Then run it again to see if it is clean; if it is you have a good chance that the drive will be fine. If not it is going to be dead soonish...

setup degraded array using raidframe
Hi misc! First of all i'm a newbie, so please excuse my lack of knowledge. Now, let's get to the point. I'm trying to setup a raid 1 degraded array using RAIDFRAME. I'm using a PII machine with hard-drives wd0,wd1. Step 1) a) recompiled the kernel with pseudo-device raid 4 option RAID_AUTOCONFIG b) recompiled userland. c) made a release. 4) made a bootable iso image from the release files and burned that image on a CDROM. Step 2) a) install base system with the new boot cd on wd0. b) fdisk -i wd1; disklabel -E wd1.

Re: brute force voip QoS
1. Your topology: On the inside lan, are you hosting clients or
service? So is this an outside-to-inside -or- an inside-to-outside
problem?
2. altq queue-type priq effectively does what your asking -- if voip
traffic is allocated to priority 6, then nothing flows from queues 5, 4,
3, 2, and 1 while the q6 bucket is wet.
I run altq priq on my voip/sip/asterisk setups with priority 7 being
tos, 6 being voip, 5 being vpn and then general traffic at 1 and bulk
stuff at 0.
My VOIP is NEVER affected by anything else going on and works
flawlessly. I, therefore, don't understand why you'd need to or want to
go to further extreme configurations.
As for some of the other stuff raised,
use a table
table VoipSrvrProviders const \
{did.voicenetwork.ca. stun.voicenetwork.ca.}
May or may not need the static-port modifier
nat log on outside inet proto udp \
from SipClients to VoipSrvrProviders \
- (outside:0) static-port
use altq priq
altq on outisde priq bandwidth 825Kb queue { Q0, Q1, Q4, Q5VPN, Q6VOIP,
Q7 }
queue Q7 priority 7
queue Q6VOIP priority 6
queue Q5VPN priority 5
queue Q4 priority 4
queue Q1 priority 1 priq(default)
queue Q0 priority 0
If your case is an outside-to-inside scenario, then reverse the
directions, i.e. use either an inside-edge nat or a rdr instead.

Hi,
I would like to know if this is possible and how, regardless of what
happenned with other applications.
I would like to setup PF so that, whenever an initial voip flow was
detetcted, all other non relevant traffic would be blocked, and normal
packet flow being restored only after some voip idleness be detected.
Can it be done? Can someone give some ideas of how?
Thanks in advance.
Best regards,
Jeff.

OT: Can an SSH alternative to WebDav be use on OpenBSD
Hi, I need some possible suggestions if I may asked to not setup, or have to setup WebDav on OpenBSD to allow users to do their web folder stuff. It can be setup with ftp for example to allow them to map a folder in their network place on XP for example, but then they can't do the stupid save as and just for that, they want to use the WebDav. However, then it need to allow write access via http and the full load of issues that could with that when combine with php, etc. I only allow ssh access and in very special case, I had accepted ftp from specific locations control via PF, but because of the stupid save as, they are screaming for WebDav, or mod_dav, witch I really would like to avoid totally. I just don't see the benefit worth the risk required to allow it. May be I am wrong and someone could in light me, witch I would very much appreciate, but again, may be there is an alternative using SSH that I do not know. I provided WinSCP years ago and it sure works well, plus I can control access via ssh with PF too, witch I would loose introducing WebDav. I hate all these users that can only work using a GUI like interface all the time and fell they need everything to be done via http. Anyone can provide me some ideas, or alternative here as I am running out of them and being view as the asshole that always refuse flexibility for security is fine, but may be there is something I can do to keep it safe and give the winers a bone. I hate the Microsoft centric bias users that care less for security, but would also be the first to scream should there be compromise too. Any suggestions here? Sorry for the somewhat off topic question, but I need suggestion if there is any. Best, Daniel.

I really didn't fully understand you - do you want or not to allow FTP acces, and why clients are not able to save as when using it? Do you mean that they need it mapped as a network drive? If so, they can use something like this: http://www.acs.uwosh.edu/novell/netdrive.htm to map the FTP account you provide to their own PC as a drive. Then they can use whatever they want to read/edit/write stuff. Sorry for the fuzz if i've misunderstood you. Kind regards, Doichin

It's also configure in the My Network Places of XP, but they can't from that work live on the server for example, or do save as from inside applications as this ftp mapping do not map to drive if you want. This might work, but I can't download as it does required an account. Might work. Sorry for the fuzz if i've misunderstood you. Kind regards, Doichin
