Hey all,

I have been a user of GNU/Linux for a long time. I recently built my
own custom router with the following components:
RouterBoard R52N WiFi miniPCI card with the AR9220 Chipset: http://www.routerboard.com/index.php?showProduct=72
Soekris net5501
Traverse Solos Multi-Port ADSL2+ PCI Modem: http://www.traverse.com.au/productview.php?product_id=116

I did some research and found the OpenSoekris project, so I know there
is compatibility with that. However, I am having trouble finding out
if the other hardware is compatible with OpenBSD 4.7. How well is
Wireless N supported with the Athn driver? Can WPA2 be done with that
without it stop responding after a while. I have this issue with the
current Linux drivers where I think it's hostapd will just stop
responding and disconnect everyone on wireless. How reliable is the
Wireless N with that chipset here?

Also, I have looked for information on the Multi-port ADSL card for
BSD, but have not really found anything. Is this card supported. The
so how do I use it? The command on Linux is:
pppd plugin pppoatm.so 0.0.38 user username password password noauth
This card requires extra information to be sent to pppd to designate
the port. The first port is 0.VCI.VPI, so the second one is 1.VCI.VPI.

I need to be able to do multi-wan with two ADSL2+ connections.

One of the main reasons for wanting to switch is PF. I am having some
very major performance issues with iptables. I've read a lot of great
things about PF when I did search on replacement firewalls. There's
also other reasons for wanting to switch, as well.

One thing that I would like to continue to do is filter packets based
on type, namely P2P type packets. I want to give them a low priority
in the QoS. On Linux, I use Layer7 rules, is there something similar,
or the same for OpenBSD? Also, is it possible to block those packets
between certain times and at other times, just reduce the priority?

These are all the questions I can think of at the moment. The big
thing that I need to know before I switch, is if the hardware is
compatible. I can't take the router off line just to check since there
are people using it. I would need to build the image with all settings
first, and then test via bootp or something like that.

Thanks,
Jon

Hi,

regarding wireless you can check here http://www.openbsd.org/faq/faq6.html#Wireless  especially read caveats
section here  http://www.openbsd.org/cgi-bin/man.cgi?query=athn&sektion=4
(no n-version yet)

Regarding modem I can't find it here http://www.openbsd.org/cgi-bin/man.cgi?query=pci&sektion[..]
. Do you have some outputs available from Linux like some detection
from dmesg, scanpci, lspci ?

In-kernel version of ppp http://www.openbsd.org/cgi-bin/man.cgi?query=pppd&apropo[..]

In-userland version of ppp http://www.openbsd.org/cgi-bin/man.cgi?query=ppp&apropos[..]

pf(4) doesn't work on Layer 7. Anyway all info needed is here http://www.openbsd.org/faq/pf/index.html  and of course in man pages.
I'm not sure right now, but there may be some apps in packages/ports
which provide that functionality.

So it looks like OpenBSD is however not right solution for you right now.

How reliable is the

To my knowledge, there is no 802.11N support in OpenBSD. Read the last
paragraph:

http://www.openbsd.org/cgi-bin/man.cgi?query=athn&sektio[..]

That modem isn't going to work, sorry. I think you'll need an ueagle(4)
( http://www.openbsd.org/cgi-bin/man.cgi?query=ueagle&apro[..] )
modem for OpenBSD.

You'll also have problems with the wireless card: it's supported, but
not in 802.11n mode (OpenBSD doesn't do 802.11n at the moment) and not
as an access point. The somewhat similar ath(4) cards can be used as
access points.

If you still want to know, post back. (Short version: not really, but
you can fake it well enough.)

As to your Linux problems: they are off-topic and I don't know enough
about Linux to help you, but have you tried a Linux list?

Layer 7?  I am assuming you mean Layer 5, where protocols like P2P and such
live,
if you happen to know the port numbers, you can do so with pf's queuing
function
I am not aware of actual time-based system, but you could create different
configs
for the different times and just use PFCTL(8) and CRON(8) to do it.  I have
done a
similar thing at work to prioritize server traffic after hours for syncing
with secondary
datacenters and cut internet access for employees to a total of 10 mbps.

That's a drastic cut.
Down to one byte every 13 minutes or so.
That will generate some agro.

This life is not the real thing.
It is not even in Beta.
If it was, then OpenBSD would already have a man page for it.

Thanks for your replies. I will investigate the freebsd link. I did
read that pf was behind in freebsd, which is why I wanted to use
OpenBSD. :)

Apparently the lspci in embedded linux is quite lacking in features.
This is the most it will give me:
00:0e.0 "Class 0203" "10ee" "0300" "0000" "0000" "solos"

as you can see by this output:
~# lspci --help
BusyBox v1.16.1 (2010-05-12 14:50:22 BST) multi-call binary.

Usage: lspci [-mk]

List all PCI devices

        -m      Parseable output
        -k      Show driver

Maybe I should install a full version of pci utils.

Thanks for your help. I can help out if anyone is writing a driver for
this card.

That's just semantics, above layer 4 it's all "application", we all
know the OSI model is broken. Parsing application protocol is often
referred as layer 7 filtering and not as layer 5 filtering.

-current has only very recently added "initial Host AP bits" for
athn(4) so you probably won't get a lot of feedback on that yet...

No. The only reasonably easily available PCI ADSL card likely to
work is Traverse's single-port one (viking, I think) which presents
as a Realtek NIC. (It's basically a separate router + a nic glued
together onto one PCI card).

You can do that with two of the 1-port cards, or some combination
with external routers, using PF route-to or multipath routing.

Deep packet inspection + QOS + ATM protocol. Not sure exactly what
Solos runs on the host cpu, maybe some of ADSL protocol too. I think
you are asking rather a lot of a low-power geode-based system...

Yes, it's the Viking:

Hi, I am interested in this "weak" point of OpenBSD, so I must say,
how can I achieve such a goal? How can I trap this packets and send
them to /dev/null for example, a guide somewhere?

I think you mean relayd(8), it has been renamed a long time ago.

But yes, the best way to do this is to force all traffic through proxies
and drop/slow everything else.
