thelowlyone Posted June 20, 2006 Share Posted June 20, 2006 I was wonder if anyone can explain to me how to set up a wireless network like the one in my school's library. The wireless network has no encryption so anyone can just hop on it. When you connect you can't access the internet until after you've opened your browser which gets automatically redirected to the library's login page and enter your student ID and PIN. After you've logged in a popup comes up that you have to keep open in order to remain connected. I want to set up a wireless network similar to this so I hope someone can at least explain to me how it would be setup and how it works. Thanks in advanced.

sentinel Posted June 20, 2006 Share Posted June 20, 2006 often they will use control server devices such as those made by http://www.gss-vernier.co.uk Quote Link to comment Share on other sites More sharing options...
stingwray Posted June 20, 2006 Share Posted June 20, 2006 Captive Portal with Radius authentication. I have that with a VPN pass through which enables me to have the actual wireless totally unsecrued (i.e. without WEP or WPA) but still know that no one is going to be able to get onto my LAN or my Internet. Never had much luck with wireless encyption myself. Quote Link to comment Share on other sites More sharing options...
Uncle Toxie Posted June 20, 2006 Share Posted June 20, 2006 This is a great topic, I was looking to do something like this at work. I wonder, is there a way to tie in a captive portal to an Active Directory server. That way the user can authenticate using their normal logon. Hmmmm, new project!

stingwray Posted June 20, 2006 Share Posted June 20, 2006 If the Captive Portal can authenticate against the Active Directory then it shouldn't have a problem. Most Captive Portals use Radius for authentication, to my memory Active Directory can be authenticated by Radius, so that would be the easiest way, but you might not want to change that over to Radius.

thelowlyone Posted June 20, 2006 Author Share Posted June 20, 2006 Thanks for all the links. I'll have to take my time looking through this new info. And is it hard to setup one of these things (Captive portals)? And is Radius hard to implement? Quote Link to comment Share on other sites More sharing options...
stingwray Posted June 21, 2006 Share Posted June 21, 2006 And is it hard to setup one of these things (Captive portals)? And is Radius hard to implement? You could replace your current router, or just set up a Monowall in the right place and that will allow you to run a Captive portal, with local user authentication. If you want to get into radius then you need to start to look at FreeRadius, but that is a beast. It seems like the config file is about 10km long, and its not particularly well documented. There are other radius servers out there but FreeRadius seems to be the most used and is past the v1.0 stage. Quote Link to comment Share on other sites More sharing options...
thelowlyone Posted June 22, 2006 Author Share Posted June 22, 2006 I've been looking into Monowall and I think thats what I'm going to be using. Quote Link to comment Share on other sites More sharing options...
