\begin{frame}{Was ist freifunk?}
\begin{itemize}
\item Initiative für freie, offene, kostenlose Netzwerke
\item Öffentlich - freifunk steht jedem offen, als Nutzer oder Anbieter
\item Im Besitz der Gemeinschaft - Wird von den Menschen betrieben, die es nutzen
\item Nicht kommerziell
\item Nur freie, quelloffene software
\item Netzneutral - keine Manipulation der Datenströme
\item In \href{http://freifunk.net/wie-mache-ich-mit/community-finden/}{69 Orten} gibt es bereits Freifunknetze mit mehr als 3300 Zugangspunkten
\end{itemize}

Was ist ein mesh?
\begin{itemize}
\item to mesh = Englisch: vermaschen
\item Selbst organisierende Netzwerke
\item Jeder Router ist automatisch aktiver Teil des Netzwerks
\item hamburg.freifunk.net Nutzt das Protokoll B.A.T.M.A.N.-adv.
\end{itemize}
Zwei SSIDs
\begin{itemize}
\item Freifunk Zugang: hamburg.freifunk.net
\item Mashing (adhoc): f8:d1:11:87:52:2e

\begin{frame}{Sicherheit}
\begin{itemize}
\item Da freifunk kein Kennwort nutzt, ist die Funkstrecke zum Zugangspunkt (wie bei allen offenen WLANs) unverschlüsselt
\item Wie sonst im Netz auch, nutzt nach Möglichkeit Ende-zu-Ende-Verschlüsselung
\item Verbindungen über die gateways laufen durch VPNs und sind verschlüsselt --> kein Zugriff auf das „Heimnetzwerk“ möglich
\end{itemize}
\end{frame}
%11
\begin{frame}{Störerhaftung}
\begin{itemize}
\item Die Zugangspunkte gehen nicht direkt in das Internet
\item Es wird über das Internet eine verschlüsselte VPN-Verbindung zu den gateways aufgebaut
\item Selbst die gateways sind nicht die Ausgänge ins GBI, sondern bauen wiederum VPNs ins Ausland auf
\end{itemize}
\end{frame}

\begin{frame}{Dienste}
Implementiert
\begin{itemize}
\item Internet
\item Stadtweites Intranet (IPv4 \& IPv6)
\item Internet Dienste \href{http://hamburg.freifunk.net/wo-wird-gefunkt\#Dienste}{http://hamburg.freifunk.net/wo-wird-gefunkt\#Dienste}
\item Verbindungen zu anderen Städten und Netzwerken sowie deren Diensten
\end{itemize}
\end{frame}
%13
\begin{frame}{Wie kann man mitmachen?}
\begin{itemize}
\item Alle können Freifunker\textunderscore innen werden, besondere technische Kenntnisse sind nicht notwendig
\item Werde ein Teil des Netzwerks, indem du bei dir im Haus einen Freifunk-Knoten aufstellst
\item Treffen jeden Montag ab 19:45 Uhr in den Rämen des CCCHH (z.Z. Humanist Lab)
\item Verbreite die Idee! Entwickelt mit!
