I can do ssh from one server to another using this:
# ssh root#1.2.4.148
The following code is doing the same in pythonic way:
import paraminko
#paramiko.util.log_to_file('ssh.log') # sets up logging
client = paramiko.SSHClient()
client.load_system_host_keys()
client.connect('1.2.4.148')
stdin, stdout, stderr = client.exec_command('ls -l')
But if I need to connect to third server from the second server, I can do this:
# ssh -t root#1.2.4.148 ssh root#1.2.4.149
How is this done in python?
My current server (250) has password less keys saved with 148 server for easy access. But connection to 149 from 148 will need password if that matters.
This python function will connect to middle_server first and then to last_server. It will execute the command "mycommand" on last_server and return it's output.
def myconnect():
middle_server='1.2.3.4'
middle_port=3232
middle_user='shantanu'
middle_key_filename='/root/.ssh/id_rsa.pub'
last_server='6.7.8.9'
last_port=1224
last_user='root'
last_password='xxxxx'
mycommand='pwd'
import paramiko
proxy_client = paramiko.SSHClient()
proxy_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
proxy_client.connect(middle_server, port=middle_port, username=middle_user, key_filename=middle_key_filename)
transport = proxy_client.get_transport()
dest_addr = (last_server, last_port)
local_addr = ('127.0.0.1', 1234)
channel = transport.open_channel("direct-tcpip", dest_addr, local_addr)
remote_client = paramiko.SSHClient()
remote_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
try:
remote_client.connect('localhost', port=last_port, username=last_user, password=last_password, sock=channel)
(sshin1, sshout1, ssherr1) = remote_client.exec_command(mycommand)
print sshout1.read()
except:
print "error"
return 0

I have to extract backups from Mikrotik with python and save them in my server so these backups are saved in my computer and also on the servers. I've been searching for info about it but didn't have any luck. Can someone help me?
""" Authentication for remote desktops through ssh protocol """
import paramiko
from getpass import getpass

You cannot do that with plain SSH. It will execute RouterOS commands (so no ls). The task can be done with FTP or SFTP (if you prefer SSH) client:
$ sftp admin#192.0.2.1
admin#192.0.2.1's password:
Connected to 192.0.2.1.
sftp> ls
flash
sftp> cd flash
sftp> ls

sftp> get MikroTik-20210509-1756.backup

I have a manual process of port forwarding using OS based SSH forwarding currently and I would like to do this through Python so that the connection auto closes after. Similar to how a 'with open' would work for a file write.
I am currently using it like so:
ssh jumpserver -L 8000:internal_server_name:8000 -N
and calling the api locally like so:
http://localhost:8000/get-answer/
This method works, but again, I am looking for a using/with open method.
I tried this without luck:
remote_host = "internal_server_name"
remote_port = 8000
local_port = 8000
ssh_host = "jumpserver"
ssh_port = 22
user = "ubuntu"
pkey = "~/.ssh.id_rsa"
transport = paramiko.Transport((ssh_host, ssh_port))
# Command for paramiko-1.7.7.1
transport.connect(hostkey = None,
username = user,
password = None,
pkey = pkey)
try:
forward_tunnel(local_port, remote_host, remote_port, transport)
except KeyboardInterrupt:
print ('Port forwarding stopped.')
sys.exit(0)
I use Python flask and paramiko to execute command on my remote ssh server from my html form.
It should to display the message back to my html file:
(result from the executed file in ssh server)
Any Idea or Website Link are welcoming
Thank you.
You can use something like this within a function. Once the function is called return the "output" to the html.
import sys, paramiko
if len(sys.argv) < 4:
print "args missing"
sys.exit(1)
hostname = sys.argv[1]
password = sys.argv[2]
command = sys.argv[3]
username = "admin"
port = 22
try:
client = paramiko.SSHClient()
client.load_system_host_keys()
client.set_missing_host_key_policy(paramiko.WarningPolicy())
client.connect(hostname, port=port, username=username, password=password)
stdin, stdout, stderr = client.exec_command(command)
output = stdout.read(),
finally:
client.close()
I am using Python 3.6.6 and i need to establish a SSH connection to a server.
I have the IP and port for the server, and i use my credentials to login, usually through putty. The servers is on Linux/Suse .
I need to get the list of directories in the server folder, and copy the content of one of the files out. I am using paramiko, and i need the connection to be open so i can execute and interact with the server.
I am not sure i am clear enough.
Below is my code
import paramiko
nbytes = 4096
hostname = '123.123.123.123'
port = 22020
username = 'uname'
password = 'pwd'
command = 'vi log'
client = paramiko.Transport((hostname, port))
client.connect(username=username, password=password)
stdout_data = []
stderr_data = []
session = client.open_channel(kind='session')
session.exec_command(command)
while True:
if session.recv_ready():
stdout_data.append(session.recv(nbytes))
if session.recv_stderr_ready():
stderr_data.append(session.recv_stderr(nbytes))
if session.exit_status_ready():
break
print ("rec status: ", session.recv_ready())
print ("exit status: ", session.recv_exit_status())
print ("".join(stdout_data))
print ("".join(stderr_data))
session.close()
client.close()
I have the following script to connect to an custom ssh shell.
When I execute the script it just hangs. It doesnt execute the command. I suspect problems with the shell because it does not have any prompt. Do you have any idea?
import sys
import os
import paramiko
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('10.115.130.22', username='admin', password='xxx', timeout = 30)
stdin, stdout, stderr = ssh.exec_command('xconfiguration SystemUnit Name: devicename')
print stdout.readlines()
ssh.close()`
I spent way too much time on this problem. I found that I needed to use the invoke_shell() to be able to get anything past the greeting banner on the Tandberg C/E series video endpoints. Here's my working code, FWIW:
import time
import paramiko
command = 'help'
host = 'x.x.x.x'
port = 22
user = 'admin'
passwd = 'TANDBERG'
def tbgShell(host,port,username,password,cmd):
"""send an arbitrary command to a Cisco/TBG gizmo's ssh and
get the result"""
transport = paramiko.Transport((host, port))
transport.connect(username = user, password = passwd)
chan = transport.open_channel("session")
chan.setblocking(0)
chan.invoke_shell()
out = ''
chan.send(cmd+'\n')
tCheck = 0
while not chan.recv_ready():
time.sleep(1)
tCheck+=1
if tCheck >= 6:
print 'time out'#TODO: add exeption here
return False
out = chan.recv(1024)
return out
output = tbgShell(host, port, user, passwd, command)
print output
This is a custom shell. It is a cisco ex90 video conferencing system.
But I tried different commands like xconfig which show you the config.
