Re: wifiprobe script
Hi, sorry for the spam. This is an update to the wifiprobe script. For some reason the ath0 scan output differs from the ipw0, iwi0, iwn0 etc... ath0 gives the signal strength in % (of what?), whilst iwi0, ipw0, iwn0 specifies the units (dB) In any case, this is the update to the script: www.aei.mpg.de/~pau/OpenBSD_wifiprobe.sh I hope you find it useful Pau 2007/11/7, Pau Amaro-Seoane <[EMAIL PROTECTED]>: > Hi, > > I use very frequently the wireless to connect to different nets and I > have a script for personal use which probably (??) could be useful for > some of you.

Re: wifiprobe script
PS: No offense, please "I also have seen/read a lot of critics to obsd for not having a couple of tools for doing such things. I hope this helps obsd a bit" ahem... the tools are ALREADY there, of course, and they're fantastic (ifconfig, dhclient, and all iwi, iwn, ipw Damien wrote!) what I of course mean is something like a "wrapper"... for all those tools, since I personally sometimes have problems remembering the different options and I'm in a hurry or just a stupid lazybones to do "man bla"
wifiprobe script
Hi,
I use very frequently the wireless to connect to different nets and I
have a script for personal use which probably (??) could be useful for
some of you. At least some of the misc people I know asked me to post
this here.
I also have seen/read a lot of critics to obsd for not having a couple
of tools for doing such things. I hope this helps obsd a bit (???).
In any case, I hope I don't overwhelm your inbox with unwished spam. I
am sure that a lot of you have already done something similar...
This script is thought to help you find the different available
connections (named "beams" for historical reasons) where you happen to
be when you execute it. It will display them in the following order:
1- "Public" connections (i.e. without wep key)
2- "Secured" connections (i.e. with wep)
They are also shown in order according to the strength of the signal
and then you're prompted to choose the number of the beam you wish to
connect to. Of course, if a wep password is required, you will be
asked for it. Afterwards it'll connect to it.
Please note that you will have to modify the script to
a- select your IFACE (in my case iwi0)
b- select your LANG (in my case "catala", but "english" is also available)
ah, so... author? Let's say... an "anonymous donor to the public domain" ;)
A big thank you to everybody and in this occasion especially to Damien
for his great work.
Cheers,
Pau
