    55In the IRIS project we are developing a new node concept based on a separation of the 'radio interfaces' and the 'base node'.
    6 Tim Baas, student at Hogeschool Leiden has prototyped  the software as his 'afstudeerwerk'. Documentation is available in the [http://svn.wirelessleiden.nl/svn/projects/iris svn iris-directory] (in Dutch).

    89The [wiki:NanoBSD] page is the place to be for up2date information on how to build/configure/create a [http://www.wirelessleiden.nl WL] node image. As always this project could use your help, by [wiki:Contributing] to various parts of the project.
     
    1415A node, type IRIS, is built using NanoBSD with some extensions a.o. to make package management a bit easier. Also the internet gateway (providing internet connectivity to the local wireless network) is based on NanoBSD.

    16 The '''nodes''' are FreeBSD routers with slave DNS (dnsmasq), lvrouted as a dynamic internal routing daemon, thttpd webserver and a captive portal based on ipfw and tcpserver for the plain HTTP-redirects. Moreover there are some additions which are strictly speaking not essential such as network monitoring (Nagios) and bandwith measurment (iperf).

    18 A '''proxy gateway''' is a http-proxy based on tinyproxy and an authorative DNS server (maradns). Included is also
    19 reverse ssh-tunneling (for remote management behind NAT firewalls). Nodes use pen with a pen-wrapper to select the 'best' proxy (i.e. the highest bandwith). An alternative is a '''packet filtering firewall''' using ipfw to allow only port 80, 443 rate limited traffic. Packet filtering gateways use lvrouted to advertise a default route.

    26 In the course of 2009/2010 we have revamped most of our nodes (some still left to be modified in 2011) and also built some new ones. We have chosen the following hardware configuration:
    27 - nodemachine based on a Alix2D3 board with 1 GB compact flash card containing the software
    28 - 802.11a interlinks based on Ubiquity Nanostation5
    29 - local accesspoint with 8 dB omni antenna and Atheros CM9 minipci wireless card.
