Один раз вписать точку доступа это конечно удобно, но не всегда, особенно когда точки доступа постоянно меняются.
Кто чем пользуется для этого? (ifconfig ес-но не предлагать)

Нашёл хороший скрипт, дописал пару строчек и решил с вами поделиться, вдруг понадобится: https://github.com/soko1/OpenBSD/blob/master/scripts/auto-wifi.sh

А поясни как именно этот конфиг используешь, плз. Я в курсе только /etc/hostname.* , но оно не всегда удобно когда точек доступа дофига и часто меняются. Ну или может там можно сразу несколько вписывать - не пробовал ещё.

> Ну или может там можно сразу несколько вписывать - не пробовал ещё.

честно говоря, не знаю, можно ли там вписать много :) обычно использую, как в faq написано...

Самое смешное, что раньше я просто писал все пары SSID/пароль и останавливалось на первой успешной. :)
А потом перестало.

Я уже писал как то на obsd.ru ставил и пользовался вот этим http://undeadly.org/cgi?action=article&sid=20120113172334
В принципе меня устраивало.

пусть тогда скрипт тут и лежит, для коллекции :)

# NAME
#	wiconfig - simplifies the configuration of wireless interfaces 
#
# SYNOPSIS
#	wiconfig [-dqs] interface
#
# EXAMPLE
#	Manually configure a wireless interface
#
#		# sh /etc/wiconfig iwi0 
#
#	Automatically scan for wireless networks and, using previous manual
#	configurations, configure the wireless interface based on the strongest
#	wireless signal (for use with hostname.if(5) files)
#
#		$ cat /etc/hostname.iwi0
#		!/bin/sh /etc/wiconfig -q \$if
#
#	With the above /etc/hostname.iwi0 in place, iwi0 will be configured
#	upon startup or whenever /etc/netstart iwi0 is invoked.
#
#	wiconfig can also be used in conjunction with apmd(8).  In the
#	following example, upon resume, it'll check the status of the wireless
#	connection and, if there is no network connection, it'll automatically
#	scan for wireless networks and, using previous manual configurations,
#	configure the wireless interface based on the strongest wireless
#	signal.
#
#		$ cat /etc/apmd/resume
#		#!/bin/sh
#		/bin/sh /etc/wiconfig -qs iwi0
#
#	apmd will need this file to be executable so you'll want to do this as
#	well
#
#		# chmod 0744 /etc/apm/resume
#
# FILES
#	/etc/wiconfig.db	Wireless network database
#
# CAVEATS
#	1) Only DHCP is supported
#	2) No user-defined nwid prioritization--the nwid with the strongest
#		signal will always be preferred
#	3) Only the first 20 nwids with the strongest signals are used
#	4) When used within a hostname.if(5), host startup will be delayed
#		slightly while a wireless network scan is performed
#	5) Database records are never purged--existing entries will be updated,
#		but unwanted entries need to be removed manually  
#	6) Hidden nwids are not supported
