Recently i got a task , where i need to connect to linux box,copy some files and run some shell scripts before i am going to validate my UI using selenium in my windows box.
I felt both are good to use
1. Python - paramiko
2.
sshxcute
I want to share w.r.t paramiko,as for #2 , there are good examples available in the same site/page.
import paramiko
import ConfigParser
from config import *
import glob
import os
import md5
global ssh
dir_local = 'c:\paramikoLearn'
dir_remote = "/home/test"
filePattern = "*.txt"
def connectTo():
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(HOSTNAME, username=USERNAME, password=PASSWORD)
def closeConnection():
ssh.close();
def copy():
# Get paramiko Transport to negotiate SSH2 across the connection
try:
t = ssh.get_transport()
print "Start client"
if not t.is_authenticated():
print "Connect Client"
t.connect(username=USERNAME, password=PASSWORD)
t.connect
print "StartClient successful"
else:
sftp = t.open_session()
print "StartClient successful"
sftp = paramiko.SFTPClient.from_transport(t)
# BETTER: use the get() and put() methods
# for fname in os.listdir(dir_local):
for fname in glob.glob(dir_local + os.sep + filePattern):
is_up_to_date = False
if fname.lower().endswith('txt'):
local_file = os.path.join(dir_local, fname)
remote_file = dir_remote + '/' + os.path.basename(fname)
#if remote file exists
try:
if sftp.stat(remote_file):
local_file_data = open(local_file, "rb").read()
remote_file_data = sftp.open(remote_file).read()
md1 = md5.new(local_file_data).digest()
md2 = md5.new(remote_file_data).digest()
if md1 == md2:
is_up_to_date = True
print "UNCHANGED:", os.path.basename(fname)
else:
print "MODIFIED:", os.path.basename(fname),
except:
print "NEW: ", os.path.basename(fname),
if not is_up_to_date:
print 'Copying', local_file, 'to ', remote_file
sftp.put(local_file, remote_file)
t.close()
except Exception as e:
print '*** Caught exception: %s: %s' % (e.__class__, e)
try:
t.close()
except:
pass
def executeShellScript():
return ssh.exec_command("ls -l")
if __name__ == '__main__':
ssh = paramiko.SSHClient()
try:
connectTo()
output = executeShellScript()
print output[1].read()
closeConnection()
except:
closeConnection()
************
In my junit testscript by using RunTime,Process i was able to run the python script and able to complete the task. :)
