I have tried to fix it up but got the same error every time. I have tried several times also tried in google but cannot give a suitable answer.

I have some piece of code like this
import paramiko
try:
client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(IP, username=myusername,password=mypassword,timeout=3)
except:
print ("[-] Wrong : "+ip+" : "+username+" : "+password)
And when I run it, it keeps giving tracebacks about SSH problem such as this:
Traceback (most recent call last):
paramiko.ssh_exception.SSHException: Error reading SSH protocol banner
I would like to know if it is possible to not print at all on the screen any Traceback messages?
Thanks

You could just finish your try and just do a general catch and then do nothing with it.
import paramiko
try:
client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(IP, username=myusername,password=mypassword,timeout=3)
except Exception as e:
pass
Probably the best alternative would be to use the tracebacklimit module.
For Python 2.x you could do:
import sys
import paramiko
sys.tracebacklimit = 0
try:
client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(IP, username=myusername,password=mypassword,timeout=3)
except:
print ("[-] Wrong : "+ip+" : "+username+" : "+password)
For Python 3.5 (tracebacklimit) some people have reported that this should be set to None to work, i.e.:
sys.tracebacklimit = None
For multiple exception raised some people reported is not guaranteed to work (In Python, how do I print an error message without printing a traceback and close the program when a condition is not met?).
This is my code, to delete a remote directory using paramiko sftp.
import paramiko
host = "192.168.1.13"
port = 22
transport = paramiko.Transport((host, port))
username = "root"
password = "abc123"
transport.connect(username = username, password = password)
sftp = paramiko.SFTPClient.from_transport(transport)
filepath = '/root/test_folder'
sftp.rmdir(filepath)
Execute above code will output this error,

IOError: Failure
This is not the case when I'm using sftp.remove(path) for a single file. But sftp.rmdir causing IOError
The syntax is from the documentation.
The error is because the destination directory has got files inside it.
Try recurssive delete instead.. See below..
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(host,username=username,password=password)
filepath="/root/test_folder"
cmd = "rm -rf " + filepath
stdin, stdout, stderr = ssh.exec_command(cmd)

I trying use tor proxy for ssh.
First simple connection without ~/.ssh/config
~$ ssh -p <SERVER_POST> <USER>#<SERVER_HOST>
<USER>#<SERVER_HOST>'s password:
~$ echo $SSH_CONNECTION
<MY_REAL_HOST> <MY_REAL_PORT> <SERVER_HOST> <SERVER_PORT>
Second with next ~/.ssh/config:
Host *
ProxyCommand connect -4 -S 127.0.0.1:9050 $(tor-resolve %h 127.0.0.1:9050) %p
and connect:
~$ ssh -p <SERVER_POST> <USER>#<SERVER_HOST>
<USER>#<SERVER_HOST>'s password:
~$ echo $SSH_CONNECTION
<NOT_MY_REAL_HOST> <NOT_MY_REAL_HOST> <SERVER_HOST> <SERVER_PORT>
Now with paramiko:
>>> import paramiko
>>> client = paramiko.SSHClient()
>>> proxy = None
>>> client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
>>> client.connect(hostname=host, username=user, password=password,
... port=port, sock=proxy)
>>> stdin, stdout, stderr = client.exec_command('echo $SSH_CONNECTION')
>>> print((stdout.read() + stderr.read()).decode('utf8'))
<MY_REAL_HOST> <MY_REAL_PORT> <SERVER_HOST> <SERVER_PORT>
All work fine. But when I try set up proxy:
>>> import paramiko
>>> client = paramiko.SSHClient()
>>> proxy = paramiko.ProxyCommand(
... 'connect -4 -S 127.0.0.1:9050 $(tor-resolve %h 127.0.0.1:9050) %p')
>>> client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
>>> client.connect(hostname=host, username=user, password=password,
... port=port, sock=proxy)
>>> stdin, stdout, stderr = client.exec_command('echo $SSH_CONNECTION')
>>> print((stdout.read() + stderr.read()).decode('utf8'))

So connection with ssh client and tor work fine, but with paramiko not.
Why it's not work and how I can fix it for python?
I try to use python 2.7.1 and paramiko 1.12.0:
connection = paramiko.SSHClient()
connection.load_host_keys(os.path.expanduser(os.path.join("~", ".ssh", "known_hosts")))
connection.set_missing_host_key_policy(paramiko.AutoAddPolicy())
connection.connect(hostIP, 22, 'd', 'd')
command = 'ls'
(stdin, stdout, stderr) = connection.exec_command(command)
response = stdout.readlines()
errormsg = stderr.read()
But I get this error message:

This should work fine with root user on linux. If it's not, you are probably passing wrong values for hostIP (for ex: quotes in the value), username, password.
I need to upload some files using SFTP, this works from the command line:
$sftp myuser#my_remote_host
Connected to my_remote_host
sftp>
This is my Paramiko script:
#!/usr/bin/env python

port = 22
transport = paramiko.Transport((host, port))
username = "myuser"
LOCAL_PATH = "/tmp/"
REMOTE_PATH = "/dcs/tmp/"
FILE = "myfile"
transport.connect(username = username)
sftp = paramiko.SFTPClient.from_transport(transport)
path = LOCAL_PATH + FILE
sftp.put(LOCAL_PATH + FILE, REMOTE_PATH + FILE)
sftp.close()
transport.close()
print 'Upload done.'
When executing I get this error:

In your first example, you can't authenticate with only a username, so the session can't be started.
I can't tell why your privatekey example isn't working without some more information. Is it possible that its the incorrect key for that server? SSH on the command line may be trying multiple keys, or getting it from an agent.
Anyway, it easier to start off with the SSHClient class. It will wrap up all the authentication, and host verification pieces in one package. It also has an open_sftp() convenience method to return an SFTPClient instance.
