Hi everybody, just for your information - you might remember that I have been working part-time on the WiFi project in Aberdeen - a project developed by Station House Media Unit, Woodside (www.shmu.org.uk). After almost two years of development we now have a very stable WiFi infrastructure throughout north of Aberdeen - from Tillydrone through Woodside to Middlefield (and surrounding areas) with the Middlefield area completely covered with a free WiFi signal. >From the open source technologies several projects are being used extensively including: FreeRADIUS Apache httpd OpenWRT GNU/Linux Nagios Smokeping MySQL Munin bandwidthd ROSinfo NTOP Squid3 CACTI and MRTG We have also developed several in-hose scripts to gather network information using PHP, Perl, shell script (BASH) and snippets of Ruby. The WiFi network infrastructure is built using MTI AP5822E0 5GHz bridges and MOIRE access points (designed by myself using Mikrotik Routerboards http://moire.maco.sk/ ) and OpenWRT solution flashed into NanoStation2 Ubiquity devices. The wired infrastructure is a mix of Linux-based routers and gateways running Ubuntu LTS 8.04 on ML110 HP servers, HP managed switches and many different unmanaged switches. I'm trying my best to keep the infrastructure as open as possible in means of used solutions, however sometimes (like in case of Mikrotik - which is based on GNU/Linux, but has many proprietary add-ons)) there are much cheaper and more efficient solutions available on the market than OSS. OSS can become very expensive :) The network uses OpenDNS solution to make the service more secure and to filter improper traffic. We are also preparing a community-driven portal page for WiFi users based on Drupal as a part of the European-funded project Incluso (http://www.incluso.org/) . Besides other information the portal will also include webcams from some interesting spots from the target areas. I would really appreciate some help with RTP-based webcams (Axis or anything else) - my idea is to stream RTP to a Linux server, get VLC to get the stream and transcode that stream to a format which Flash understands, so it can be displayed on the website. I have developed a solution,however I'm far from feeling happy about it, so if anybody has any experience with such setup please let me know. I am totally opened to other solutions - maybe moving JPEG would do?! If you have any questions about the project or if you might want to be involved in it (let me know how:) please mail me. And - if you (or your mates) happen to live in Middlefield even better - we can get you a fast connection to the internet for free. Or a bit slower connection by simply connecting to the WiFi network (SSID: ConnectedMiddlefield) using your laptop or mobile phone. Have a great time.
