class scapy.pipetool.QueueSink(name: str | None = None)

Bases: Sink

Collects messages on the low and high entries into a Queue. Messages are dequeued with recv(). Both high and low entries share the same Queue.

   +-------+
>>-|--.    |->>
   | queue |
 >-|--'    |->
   +-------+

high_push(msg: Any) → None

push(msg: Any) → None

recv(block: bool = True, timeout: int | None = None) → Any | None

Reads the next message from the queue.

If no message is available in the queue, returns None.

Parameters:

• block (bool) – Blocks execution until a packet is available in the queue. Defaults to True.

• timeout (None, int or float) – Controls how long to wait if block=True. If None (the default), this method will wait forever. If a non-negative number, this is a number of seconds to wait before giving up (and returning None).

class scapy.pipetool.RawConsoleSink(name: str | None = None, newlines: bool = True)

Bases: Sink

Print messages on low and high entries, using os.write

   +-------+
>>-|--.    |->>
   | write |
 >-|--'    |->
   +-------+

Parameters:

newlines (bool) – Include a new-line character after printing each packet. Defaults to True.

high_push(msg: str) → None

push(msg: str) → None

class scapy.pipetool.Sink(name: str | None = None)

Bases: Pipe

Does nothing; interface to extend for custom sinks.

All sinks have the following constructor parameters:

Parameters:

name (str) – a human-readable name for the element

high_push(msg: Any) → None

Called by PipeEngine when there is a new message for the high entry.

Parameters:

msg – The message data

Returns:

None

Return type:

None

push(msg: Any) → None

Called by PipeEngine when there is a new message for the low entry.

Parameters:

msg – The message data

Returns:

None

Return type:

None

class scapy.pipetool.Source(name: str | None = None)

Bases: Pipe, ObjectPipe[Any]

deliver() → None

exhausted() → bool

class scapy.pipetool.TermSink(name: str | None = None, keepterm: bool = True, newlines: bool = True, openearly: bool = True)

Bases: Sink

Prints messages on the low and high entries, on a separate terminal (xterm or cmd).

   +-------+
>>-|--.    |->>
   | print |
 >-|--'    |->
   +-------+

Parameters:

• keepterm (bool) – Leave the terminal window open after stop() is called. Defaults to True.

• newlines (bool) – Include a new-line character after printing each packet. Defaults to True.

• openearly (bool) – Automatically starts the terminal when the constructor is called, rather than waiting for start(). Defaults to True.
