Default NetBSD 5.0 wifi/wireless network browser/scanner

I have nicely working connection using wpi(4) driver on Intel 3945abg wifi card setup with wpa_supplicant and so, but to add a new network I first have to know BOTH SSID and PRE-SHARED KEY to connect.

Is there some tool/way to get a list of available wifi/wireless networks around on NetBSD 5.0?

Maybe from pkgsrc?

Not being an ass, but perhaps you could use a linux distribution to help set those values?

According to ifconfig(8):
# ifconfig wpi0 list scan

Hope that helps.. if not, wlanctl(8) might be another option.

Umm, I don't mean to sound like a prick, but isn't this what you are looking for?

Code:
list scan       (IEEE 802.11 devices only) Display the access points
                     and/or ad-hoc neighbors located in the vicinity.  The -v
                     flag may be used to display long SSIDs.  -v also causes
                     received information elements to be displayed symboli-
                     caly.  Only the super-user can use this command.
# ifconfig wpi0 list scan

If I would want Linux this question would not happen, but thanks anyway, it works under Linux.

Thanks BSDfan666, but I have strange error (see below).

I read ifconfig man page, but somehow overlooked list scan :/

Yes apologies, I found countless mailing list entires that seem to indicate scanning for access points is.. flaky.. and that the interface needs to be up for it to work on NetBSD.

I'm pretty sure that wiconfig(8) is for a specific family of wireless drivers, but perhaps the following might work?
# wiconfig wpi0 -D

If it does not work, perhaps you should file a bug report.. or.. send an email to their mailing lists.

One reference on NetBSD's "tech-net" list indicates that net/kismet can be used to scan for access points.

http://mail-index.netbsd.org/tech-ne...msg001046.html

Ironically the topic is about how broken ifconfig+list+scan is.

Hope that helps.

Thanks BSDfan666, I checked wiconfig(8) but unfortunelly:
Code:
The wiconfig command controls the operation
of WaveLAN/IEEE wireless networking devices
via the wi(4) and awi(4) drivers.
So no go here :/

I'll try net/kismet port later, and post results here.

I also tried wiconfig wpi0 -D (no matter what the man page says) but no, it does not work.

I'll also submit a bug(s) later on NetBSD MLs, propably they know these problems but do not have time ti cope with it.

It's strange, since wpa_supplicant connection seems to be reliable on NetBSD ...

I haven't got much experience with wifi as I don't have a suported card.
Could you try to get the AP's list by using wlanctl(8)?

Also could you try:
Code:
ifconfig wpi0 mediaopts monitor
ifconfig wpi0 list scan
Are you using dhcp for that interface? Check this out: http://blog.netbsd.org/tnf/entry/introducing_dhcpcd_gtk
