ProxyCommand support

class paramiko.proxy.ProxyCommand(command_line)

Wraps a subprocess running ProxyCommand-driven programs.

This class implements a the socket-like interface needed by the Transport and Packetizer classes. Using this class instead of a regular socket makes it possible to talk with a Popen'd command that will proxy traffic between the client and a server hosted in another machine.

Instances of this class may be used as context managers.


Create a new CommandProxy instance. The instance created by this class can be passed as an argument to the Transport class.

Read from the standard output of the forked program.

size (int) -- how many chars should be read
the string of bytes read, which may be shorter than requested

Write the content received from the SSH client to the standard input of the forked command.

content (str) -- string to be sent to the forked command
