Python3 and SSH Tunnel

0 votes
1,189 views

I am trying to create one SSH tunnel, so that i can connect from a python script running on my pc, to a remote MySQL database running on my Host and id like to stick with Python 3.3 .

I contacted my host and he informed me that this is the only way.

I tried pycrypto + paramiko but from what i have noticed, paramiko is not Python 3.3 ready. Any thoughts?

First hit:
http://zeromq.github.io/pyzmq/ssh.html

Also, search PyPI for "tunnel". There might well be something useful there.

I'm not sure what exactly is going on here, but why not simply establish a tunnel using ssh(1) and then invoke your Python script separately? You simply point your script at a database on localhost, after establishing a tunnel from local 3306 to remote localhost:3306. No need to play with Python crypto.

Alternatively, can you use PostgreSQL instead? :)

Why i am getting “Paramiko : Error reading SSH protocol banner” in below code? What is the solution for it?

I have function in python,(Assume that i have imported all necessary module),

 def DL_Iperf(args):
        ssh=paramiko.SSHClient()
        ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        ssh.connect(server_ip,username="root",password=Password)
some_code

This function is actually a thread and it will be created as many no of UE i have, (Ex: if i have 1 UE than 1 Thread will be created),

So, if i have 1 UE/ 2 UE than its working but if i have 3 UE then it is failing, with error "Paramiko : Error reading SSH protocol banner",

Below is the stderr of the script,

    No handlers could be found for logger "paramiko.transport"

    Unhandled exception in thread started by <function DL_Iperf at 0x02B8ACF0>
    Traceback (most recent call last):

    File "C:\Users\qxdm-5\Desktop\Chirag\LTE_11_Perfect_Working\TCP_Latest_2\Windo
    ws_UE\slave.py", line 379, in DL_Iperf

    ssh.connect(ServerIp,username="root",password=Pwd)

    File "build\bdist.win32\egg\paramiko\client.py", line 295, in connect

    File "build\bdist.win32\egg\paramiko\transport.py", line 451, in start_client

paramiko.SSHException: Error reading SSH protocol banner

From some reference i found that this is because of some network related issue, but my question is if it network related then why everytime in 3rd call of the function i am getting this error? And how do i resolve it?

ssh and svn+ssh with different keys

Is there way to use two different keys for ssh authentication on one machine for the same user to login the same server? I need one key for svn+ssh to run command on remote server and the other key to login and work from shell on that same server.

Http tunnel via a http proxy to another http proxy server

Is that possible create a http tunnel to remote http tunnel server via a middle http proxy?

Here is my situation :
My Company only allow http protocol and they created a http proxy server. So when we want to access internet we have to set the http proxy settings for the browser or application.

Now I want to access outside without restrictions of http protocol and also not limited to 80 port. As they blocked the ssh, so the SSH reverse binding is not possible. So is that possible to create a http tunnel via the http proxy of my company and aim to my own server outside?

MySQL support for Python3?

I'm starting a new project from scratch so I think its finally a time to switch to the latest and greatest Python 3.4.

But I'm puzzled with MySQL support for Python 3. So far the only stable library I've found it pymysql.

All others are either abandoned work-in-progress projects or do not support Python 3:

  • mysqldb - Python 2.x only
  • mysql-ctypes - Python 2.x only
  • amysql - Python 2.x only
  • ultramysql - Python 2.x only
  • MySQL Connector/Python - new guy in block. Does anyone use it?
  • WebScaleSQL + MySQLdb1 - still in development, state unknown?

So what library do you use for MySQL access in Python 3? I'm specifically interested in async support (like in psycopg2 for PostgreSQL) since I'm planning to use Tornado.
