paramiko.ssh_exception.SSHException: Channel closed. Trying to connect to a remote machine with key-based...
Python noob here! I am trying to connect to a remote machine with paramiko (Python 3.7.1) with key-based authentication. Once connected I want to execute the command "ls -l" and print its output. But when I try to run the code below I get the error "paramiko.ssh_exception.SSHException: Channel closed".
import paramiko
from paramiko.transport import Transport
destination = '192.168.1.201'
port = 22
user = 'myUser'
privkey = paramiko.RSAKey.from_private_key_file ('/home/test/.ssh/test-private-key')
command = 'ls -l'
paramiko.Transport._preferred_kex = ('diffie-hellman-group14-sha1',)
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(destination,port,user,pkey=privkey)
(stdin, stdout, stderr) = ssh.exec_command(command)
print(stdout.read())
print(stderr.read())
stdin.close()
ssh.close
I have tested the SSH key-based authentication against the remote machine by using the command "myUser@192.168.1.201" which worked as intended. I also made sure that the current user (the user called test, which will run this script) has read permissions for the private key.
I can succesfully connect and run the command "ls -l" when I am not using key-based authentication with paramiko. This means I probably did something wrong when trying to get key-based authentication to work. But I just cannot figure out what I am doing wrong, I have looked up countless examples about paramiko and key-based authentication.

Where do you get the error? Show us a full stacktrace. + Show us Paramiko log file. + Show us a verbose output (ssh -vvv
switch) for your "SSH key-based authentication" test.
