\subsection{Accessing the Container}
|
||||
Access the container's shell:
|
||||
\begin{lstlisting}[language=bash]
|
||||
incus exec dnsmasq-container -- bash
|
||||
incus exec dnsmasq-container -- su - user

\section{Setting Up a Veth Pair Between Container and Network Namespace}
|
||||
To enable direct communication between a container and a network namespace, a virtual Ethernet (\texttt{veth}) pair is created. The following Python script (\texttt{link.py}) is used to create a \texttt{veth} pair between the \texttt{dnsmasq-container} (an Incus container) and the \texttt{ns1} network namespace, with interfaces named \texttt{vA} and \texttt{vB}.
|
||||
|
||||
\begin{lstlisting}
|
||||
sudo python3 link.py -n1 vA -t2 incus -ns2 dnsmasq-container -n2 vB
|
||||
\end{lstlisting}
|
||||
|
||||
This command:
|
||||
\begin{itemize}
|
||||
\item Creates a \texttt{veth} pair with one end (\texttt{vA}) in the default namespace and the other end (\texttt{vB}) in the \texttt{dnsmasq-container}'s network namespace.
|
||||
\item Ensures the interfaces are set up and operational, allowing network traffic to flow between the container and the \texttt{ns1} namespace (or default namespace if \texttt{ns1} is not explicitly created).
|
||||
\end{itemize}
|
||||
|
||||
The script uses the \texttt{pyroute2} library to manage network interfaces and namespaces, and supports container types such as Incus, LXC, LXD, and Docker. Ensure the \texttt{dnsmasq-container} is running in Incus before executing the command.
|
||||
|
||||
\subsection{Installing dnsmasq}
|
||||
Update the package list and install \texttt{dnsmasq}:
