The network configuration in Kamikaze is stored in \texttt{/etc/config/network}
|
|
and is divided into interface configurations.
|
|
Each interface configuration either refers directly to an ethernet/wifi
|
|
interface (\texttt{eth0}, \texttt{wl0}, ..) or to a bridge containing multiple interfaces.
|
|
It looks like this:
|
|
|
|
\begin{Verbatim}
|
|
config interface "lan"
|
|
option ifname "eth0"
|
|
option proto "static"
|
|
option ipaddr "192.168.1.1"
|
|
option netmask "255.255.255.0"
|
|
option gateway "192.168.1.254"
|
|
option dns "192.168.1.254"
|
|
\end{Verbatim}
|
|
|
|
\texttt{ifname} specifies the Linux interface name.
|
|
If you want to use bridging on one or more interfaces, set \texttt{ifname} to a list
|
|
of interfaces and add:
|
|
\begin{Verbatim}
|
|
option type "bridge"
|
|
\end{Verbatim}
|
|
|
|
It is possible to use VLAN tagging on an interface simply by adding the VLAN IDs
|
|
to it, e.g. \texttt{eth0.1}. These can be nested as well.
|
|
|
|
This sets up a simple static configuration for \texttt{eth0}. \texttt{proto} specifies the
|
|
protocol used for the interface. The default image usually provides \texttt{'none'}
|
|
\texttt{'static'}, \texttt{'dhcp'} and \texttt{'pppoe'}. Others can be added by installing additional
|
|
packages.
|
|
|
|
When using the \texttt{'static'} method like in the example, the options \texttt{ipaddr} and
|
|
\texttt{netmask} are mandatory, while \texttt{gateway} and \texttt{dns} are optional.
|
|
DHCP currently only accepts \texttt{ipaddr} (IP address to request from the server)
|
|
and \texttt{hostname} (client hostname identify as) - both are optional.
|
|
|
|
PPP based protocols (\texttt{pppoe}, \texttt{pptp}, ...) accept these options:
|
|
\begin{itemize}
|
|
\item{username} \\
|
|
The PPP username (usually with PAP authentication)
|
|
\item{password} \\
|
|
The PPP password
|
|
\item{keepalive} \\
|
|
Ping the PPP server (using LCP). The value of this option
|
|
specifies the maximum number of failed pings before reconnecting.
|
|
The ping interval defaults to 5, but can be changed by appending
|
|
",<interval>" to the keepalive value
|
|
\item{demand} \\
|
|
Use Dial on Demand (value specifies the maximum idle time.
|
|
|
|
\item{server: (pptp)} \\
|
|
The remote pptp server IP
|
|
\end{itemize}
|
|
|
|
For all protocol types, you can also specify the MTU by using the \texttt{mtu} option.
|
|
|
|
\subsubsection{Setting up static routes}
|
|
|
|
You can set up static routes for a specific interface that will be brought up
|
|
after the interface is configured.
|
|
|
|
Simply add a config section like this:
|
|
|
|
\begin{Verbatim}
|
|
config route foo
|
|
option interface lan
|
|
option target 1.1.1.0
|
|
option netmask 255.255.255.0
|
|
option gateway 192.168.1.1
|
|
\end{Verbatim}
|
|
|
|
The name for the route section is optional, the \texttt{interface}, \texttt{target} and
|
|
\texttt{gateway} options are mandatory.
|
|
Leaving out the \texttt{netmask} option will turn the route into a host route.
|
|
|
|
\subsubsection{Setting up the switch (currently broadcom only)}
|
|
|
|
The switch configuration is set by adding a \texttt{'switch'} config section.
|
|
Example:
|
|
|
|
\begin{Verbatim}
|
|
config switch "eth0"
|
|
option vlan0 "1 2 3 4 5*"
|
|
option vlan1 "0 5"
|
|
\end{Verbatim}
|
|
|
|
On Broadcom hardware the section name needs to be eth0, as the switch driver
|
|
does not detect the switch on any other physical device.
|
|
Every vlan option needs to have the name vlan<n> where <n> is the VLAN number
|
|
as used in the switch driver.
|
|
As value it takes a list of ports with these optional suffixes:
|
|
|
|
\begin{itemize}
|
|
\item{\texttt{'*'}:}
|
|
Set the default VLAN (PVID) of the Port to the current VLAN
|
|
\item{\texttt{'u'}:}
|
|
Force the port to be untagged
|
|
\item{\texttt{'t'}:}
|
|
Force the port to be tagged
|
|
\end{itemize}
|
|
|
|
The CPU port defaults to tagged, all other ports to untagged.
|
|
On Broadcom hardware the CPU port is always 5. The other ports may vary with
|
|
different hardware.
