autoconnect to wifi (script)

[22decembre]

In order to automatize connection to the several wifi network in which my opebsd netbook travel, I tried to write a small script. Here it is :

#!/bin/sh

CONF=/etc/wifi-conf

. $CONF

# void any previous conf
ifconfig $IF -nwid -wpakey

# scan wifi network, list them by network name, and get rid any "nwid" still there
SCAN=`ifconfig $IF scan|grep nwid|cut -d" " -f 2|sed '/nwid/d'`

# read the list of known nets
while read line
do
	# the first args of each line is the net name
	NET=`echo $line|cut -d" " -f 1`

	# the second is the key
	KEY=`echo $line|cut -d" " -f 2`

	# we compare the name to the list of scanned nets
	for ID in $SCAN
	do
		if [ $NET = $ID ]; then
			ifconfig $IF nwid $ID wpakey $KEY
			ifconfig $IF up
			
			if [ $AICCU ]
			then
				aiccu start
			fi
		fi
	done

done < $LIST

The objective is that, as soon as the laptop find a network that I have credentials, it connects. Currently, this does not work at all and it's painfull !

If someone has knowledge of a script working for that purpose, I would use it of course !

Here is the conf :

IF=ral0

AICCU=true
RTSOL=true
DHCP=true

LIST=/etc/wifi-net

and the list of known nets :

What's not working? What does it do, what does it not do?

You don't seem to be running dhclient but I don't even know if you make it that far...

It connects often to a network I can't use.

I placed rtsol and dhcp request in hostname.ral0. I expect that it works when upping ral0.

Apparently not !

So at the end, yes I should dhcp, rtsol and aiccu if I don't have native ipv6 (which I have at home, but not in the two other networks.

But first, I would like that it connect/get an active link to a network I am allowed / have the credentials.

I don't have wifi on this system so I can't try the script as a whole.

I'd echo the value of ID and NET just before you compare them and make sure you are seeing expected values. Then if it's an ifconfig issue, we can focus on that.

Ifconfig doesn't use hostname.if, /etc/netstart does.

My solution to this problem, instead of maintaining a bunch of extra files, would be to configure each access point in hostname.if.nwid and then use the script to copy the right file as hostname.if and and run netstart.

Quite a smart idea ! Yet, I don't know... Will try.

Currently, it works.

Will test in real conditions tomorrow (as I am going in the two other networks).

The ksh(1) -x option is your friend.

Just a few remarks as of last experiments for today :

I don't know why but "rtsol" alone doesn't work in this precise environnement, thus, I don't have ipv6 whereas I have native here (at home). To have it, I had to run it like a command at the end of my hostname file for the local network.

...
blabla...
up
dhcp
rtsol
!rtsol ral0

I launch the script through rc.local. It loads after slim. And bizarrely, slim doesn't run anymore after it. So I launch a graphical session after a text login.

I Tried autoconf, and it failed indeed. But not inet6 autoconf.

Thanks !
