The RawSocket app is a bridge between Linux network interfaces (eth0, lo, etc.) and a Snabb app network. Packets taken from the rx port are transmitted over the selected interface. Packets received on the interface are put on the tx port.

Configuration

The RawSocket app accepts a string as its configuration argument. The string denotes the interface to bridge to.

UnixSocket App (apps.socket.unix)

The UnixSocket app provides I/O for a named Unix socket.

Configuration

The UnixSocket app takes a string argument which denotes the Unix socket file name to open, or a table with the fields:

• filename - the Unix socket file name to open.
• listen - if true, listen for incoming connections on the socket rather than connecting to the socket in client mode.
• mode - can be "stream" or "packet" (the default is "stream"): the difference is that in packet mode, the packets are not split or merged (in both modes packets arrive in order).

NOTE: The socket is not opened until the first call to push() or pull(). If connection is lost, the socket will be re-opened on the next call to push() or pull().
