Gliederung
- introduction: Original motivation and project history
- technology
- officially supported Access Points - Linksys WRT54g and Asus WL-500g
- IEEE80.211 compliant WIFI (ad-hoc mode), IPv4, OLSR
- node types
- stationary nodes
- antennas placed on the roof
- APs placed inside flats or offices
- to maintain an effective infrastructure, the association owns and administers APs at some important locations
- mobile nodes
- basically just notebooks with wifi-cards that run OLSR
- usable anywhere in the area serviced by ON
- stationary nodes
- history of infrastructure development
- temporary installations for test purposes
- point-to-point connections using highly directional antennas
- growth; mixed use of directional antennas and omnidirectional antennas placed inside of buildings
- tendency of members to attempt to establish direct wifi-links to APs linked by LAN to an internet-gateway, stagnation
- growth and increase of redundant routes through increase in AP density and use of less directional antennas
- history of transmission protocols
- WDS; bridging; ethernet Spanning Tree Protocol to deactivate redundant routes
- ad-hoc mode; IPv4 routing; OLSR
- address spaces
- gateway "titan"
- SNAT Opennet -> Internet
- OpenVPN 2.0; authentication through certificates signed by our CA
- DNAT (i.e. port forwarding) to openvpn Addresses; currently 10 ports per user
- DSL; theoretical bandwith 3000/384 (kbit/s)?
- logging of individual connections
- Ocellata - Connection Quality; measured by using ICMP ECHO Requests
- Crinoidea (MySQLdb) - topN IP Addresses according to ON-Internet traffic caused
- Alfredi (PIM) - Maps with colored nodes and connections
- Ketupo (olsrd, olsrd_dd_ti, dot, Pydot) - Topology Dot Graphs
- Teucrium (netfilter, rrdtool, pyrddtool) - Traffic Graphs
- interfaces for users
- ethernet on their own AP
- possibility of using a second AP for private wireless use
- OpenVPN for internet-routing (endpoints on user-APs or client-systems)
- ethernet on their own AP
- Acccess Point Firmware
- started out using Sveasoft's Alchemy on Linksys, default FW on Asus APs
- current versions based on OpenWRT
- legacy ON FW: based on Freifunk-Firmware 1.0.2, minor modifications
- "Opennet Firmware" based on OpenWRT whiterussian (currently rc2) (several modifications, including the FFF-webinterface)
- web-based installation and configuration possible
- OpenVPN use on the AP explicitly supported; automated certificate creation
- individual extensions still possible, of course
- social issues
- general structure
- loosely organized, no pervasive hierarchical structure
- high importance of technologically skilled members
- day-to-day operation
- workshoops and meetings - also effective ways for interested persons to get involved
- documentation (e.g. HOWTOs) is collaboratively maintained on the ON wiki
- communication mostly per Forum, IRC and e-mail
- increasing interest in public relations issues
- motivation for individual members
- cheap internet access
- relatively fast internet access compared to the alternatives in areas without DSL coverage
- interest in technology / the community / ideological issues
- mobile internet access in the covered area
- general structure
- organisation
- some explicit internal rules
- responsibility for most of the infrastructure lies with AP-owners (i.e. individual members)
- individual competent members responsible for
- firmware design
- gateway administration
- management of jointly owned APs
- Public Relations
- support of new members
- future relevance
- connecting villages without broadband-coverage?
- supported by people interested in technological and social issues in areas covered by broadband
- mobile use
- guesstimated use of communication methods
- 45% - Forum (Wortlab Burning Board)
- 30% - Wiki (Mediawiki)
- 15% - Opennet IRC, increasing relevance
- 6% - Opennet mailing list (Mailman)
- 3% - Opennet Mail (apXX@..)
- 1% - Gallery
