this one helps. Here is an example for you. It can work as a ssh client. No need to recreate session everytime.
code :
#!/usr/bin/env python
#-*- coding:utf-8 -*-

import os,sys  
import paramiko    
import threading    
import platform  

curr_ssh = None   
curr_prompt = ">>"  

#how to use it    
def printUsage():  
    print "    !ls                     :list sessions."  
    print "    !session id             :connect session."  
    print "    !conn host user password:connect host with user."  
    print "    !exit                   :exit."  

#connect using paramiko   
def conn(ip,username,passwd):  
        ssh = paramiko.SSHClient()    
        print "Connect to ",ip," with ",username  
        global curr_prompt  
        return ssh  
        return None  

#get former session
def loadSessions():  
    global sessions  
        f = open("sessions")  
        sessions = f.readlines()  

#main function   
def exe_cmd_local(cmd):  
    if(cmd == "!ls"):  
        global sessions  
        print "Sessions:"  
        for s in sessions:  
            print"[%d] %s" %(i,s)  
        vals = cmd.split(' ')  
            id = (int)(vals[1])  
                os_name = platform.system()  

                new_console_cmd = ""  
                if(os_name == "Linux"):  
                    new_console_cmd="gnome-terminal -e \"./ssh.py " + sessions[id]+"\""  
                elif(os_name == "Windows"):  
                    new_console_cmd="start ssh.py " + sessions[id]  
                print "Didn't hava sessoin ",vals[1]  
            global curr_ssh  
            curr_ssh = conn(vals[1],vals[2],vals[3])  
            f = open("sessions","a")  
            line = vals[1]+" "+vals[2]+" "+vals[3]+"\n"  

#execute command remotely    
def exe_cmd_ssh(ssh,cmd):  
    if(ssh == None):  
        print "Didn't connect to a server. Use '!conn' to connect please."  
    stdin, stdout, stderr = ssh.exec_command(cmd)    
    print stdout.read()  
    print stderr.read()  

if __name__=='__main__':  
        curr_ssh = conn(sys.argv[1],sys.argv[2],sys.argv[3])  
    while True:  
        cmd = raw_input(curr_prompt)  

        if(cmd == "!exit"):  
            if(curr_ssh != None):  
            if(cmd[0] == '!'):

wish help you to fix your issue I tried the code and it ran fine. I made only a few changes.
First, I didn't know what "user" and "db" are, so I commented out
code :
import user, db
database = db.Database()
Does paramiko close ssh connection on a non-paramiko exception

Does paramiko close ssh connection on a non-paramiko exception

To fix this issue No, paramiko will not automatically close the ssh / sftp session. It doesn't matter if the exception was generated by paramiko code or otherwise; there is nothing in the paramiko code that catches any exceptions and automatically closes them, so you have to do it yourself.
You can ensure that it gets closed by wrapping it in a try/finally block like so:
code :
client = None
    client = SSHClient()
    stdin, stdout, stderr = client.exec_command('ls -l')
    if client:

Max value of Paramiko SSH connection timeout?

Max value of Paramiko SSH connection timeout?

Date : March 29 2020, 07:55 AM
I hope this helps you . I think you have to set it at kernel level. Paramiko set the timeout via socket.settimeout(), and this through the OS (I'm not sure of this, but your case seems so). Linux have its timeout set to 20 seconds (read this). In that same link, they explain how to increase the socket timeout:
