v23 v24 4 4 5 5 In 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). 6 7 Tim Baas, student at [http://hsleiden.nl Hogeschool Leiden] has prototyped the software as his ''afstudeerwerk''.

As always this project could use your help, by [wiki:Contributing] to various parts of the project. … … 14 15 A 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. 15 16 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).17 The '''nodes''' are FreeBSD routers with slave DNS ({{{dnsmasq}}}), {{{lvrouted}}} as a dynamic internal routing daemon, {{{thttpd}}} webserver and a {{{python}}} based [wiki:WLCaptivePortal captive portal] based on {{{ipfw}}} and {{{{tcpserver}}} for the plain HTTP-redirects.

Included is also19 reverse ssh-tunneling (for remote management behind NAT firewalls). Nodes use pen with a pen-wrapperto 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.19 A '''proxy gateway''' is a http-proxy based on {{{tinyproxy}}} and an authorative DNS server ({{{MaraDNS}}}).

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 minipciwireless card.27 In the course of 2009/2010/2011/2012 we have revamped most of our nodes (some still left to be modified in 2012) and also built some new ones.
