I would like to execute some commands on the remote server . Usually that command took 1 hour to complete the task on the remote server .

But this module failed as below .

PROMPT = '.*\$\s+'

Used the above mentioned PROMPT value.

Traceback (most recent call last): File "/usr/local/lib/python3.7/site-packages/paramiko/channel.py", line 699, in recv out = self.in_buffer.read(nbytes, self.timeout) File "/usr/local/lib/python3.7/site-packages/paramiko/buffered_pipe.py", line 164, in read raise PipeTimeout() paramiko.buffered_pipe.PipeTimeout

During handling of the above exception, another exception occurred:

Traceback (most recent call last): File "code.py", line 71, in main interact.expect(PROMPT) File "/usr/local/lib/python3.7/site-packages/paramiko_expect.py", line 144, in expect current_buffer = self.channel.recv(self.buffer_size) File "/usr/local/lib/python3.7/site-packages/paramiko/channel.py", line 701, in recv raise socket.timeout() socket.timeout

Kindly let me know your comments on this issue

The default timeout is 60 seconds, use the timeout parameter to set it to something longer then your command

@k-jayaraman @fruch If the timeout increase is not solving the problem then use the keepalive factor along with the timeout which is mentioned below.

            self._connection = SSHClientInteraction(self.client, timeout=<use_timeout_number>, display=True, buffer_size=2048)
            self._connection.channel.transport.set_keepalive(2)
