WLAN configuration
Hi all, it's a bit embarrassing, but I have troubles connecting to a _free_ Wlan AP. I mean the type where you first have to enter an arbitrary address in the browser, and then get redirected to a server page which asks you for a password. With the standard Crux configuation this doesn't work. Any ideas? Bernd -- http://sudrala.de
It sounds like you're describing some kind of traffic re-routing, like in a hotel where it pushes you to the hotel's site first no matter what so you can authenticate, then it changes your vlan to one with WWW access. I think it's called a radius server, but is that the situation you're in? You might need to tinker with your dns settings. On Tue, Nov 1, 2016 at 5:12 AM, Bernd Eggink <monoped@sudrala.de> wrote:

Yes, that is the situation - in hotels, hospitals etc. Do you know which settings exactly have to be changed? Thanks, Bernd
I do not, but the next time I go to a Starbucks and use their Wifi, I'll take note for you. On Tue, Nov 1, 2016 at 1:26 PM, Bernd Eggink <monoped@sudrala.de> wrote:

I've never encountered one where there was a URL provided. What I've been provided is the SSID of their wireless network. If that is the case then I do the following. What is important is to let the facility set your IP address and the address for the DNS in /etc/resolv.conf. This is so when you use your browser to go _any_ URL it will redirect it to the providers page where you use the authentication provided by the hotel, if any. For me the tricky part is the SSID of the facility. The front desk usually provides it but they often mispell it. Then, as root, I use ip link set wlan1 up iwlist wlan0 scan to find the correct spelling in the ESSID output. I then put the correct SSID in the wpa.conf and start wpa_supplicant. If they only use WEP (unsecured) I use a wpa.conf like: ap_scan=1 ctrl_interface=/var/run/wpa_supplicant network={ scan_ssid=1 ssid="Super8 Drumheller" key_mgmt=NONE } Then I use /sbin/dhcpcd -4 wlan0 to get their IP for my laptop and it automatically sets /etc/resolv.conf and the router gateway needed. After that I fire up my web browser and try to go to google.com. It gets intercepted by the facility and I end up at their login page. I enter the provided credentials. After that their DNS servers will correctly resolve google.com If they should have WPA2 (secured) I use a wpa.conf like: ap_scan=1 ctrl_interface=/var/run/wpa_supplicant network={ scan_ssid=1 proto=WPA RSN key_mgmt=WPA-PSK pairwise=CCMP TKIP group=CCMP TKIP ssid="Astoria Hotel Dickinson" psk="<key the desk gave me>" } Good luck! -Daryl

Daryl, your example was very helpful, thanks a lot! I got it working quickly. The only thing I had to change was "iwlist wlan0 scan", which doesn't work on my system. I use "iw dev wlp2s0 scan" instead. IMHO your example should go into the manual, or (commented out) into /etc/rc.d/net. Thanks again, Bernd
