os.mkdir() and ssh

[Ismatus3]

Hello all , I just need to create a folder in an other machine using ssh or samba ; for example i execute :

os.mkdir( rachid@rachid:/home/rachid/Bureau/new, 0777 );

but It shows the next error :

OSError: [Errno 2] No such file or directory: 'rachid@rachid:/home/rachid/Bureau/new'

Thank you for answering .

hello ismatus...... you can try pexpect module to do the same thing......try it....

[Ismatus3]

Hello sun , thank you for answering , can you give an exemple about how to use this module please , i search right now to see how it is working .

If you're with python 2, try ssh with paramiko. See this thread for examples http://www.daniweb.com/software-development/python/threads/405462

[Ismatus3]

Thank you for answering , but i couldn't understand till now how to deal with that ..

[sun_2588]

Maybe this code could help you.....you need to download the pexpect module....

try:
        enter = "Are you sure you want to continue connecting"
        password_type ="password:"
        p=pexpect.spawn("ssh 192.168.101.101 folder_name")

        i=p.expect([enter, password_type, pexpect.EOF])

        if i==0:
                p.sendline("yes")
                i=p.expect([enter, password_type, pexpect.EOF])

        if i==1:
                p.sendline("123456")
                i=p.expect([enter, password_type, pexpect.EOF])

        elif i==2:
                print "Error...."
                sys.exit(0)

except Exception as error:
                print error
                sys.exit(0)

Oh sun , thank you for your efforts , i am bigining now from down level , so i just tried :

sudo scp fichiertest.py user@10.100.8.22:/home/user/Bureau

, and it works fine after demanding our two passwords . Now i am trying to creat a new folder in that machine so i tried after searching :

sudo ssh user@10.100.8.22:/home/user/Bureau/new

, but i sent me this error message :

ssh: Could not resolve hostname 10.100.8.22:/home/hatim/Bureau/new: Name or service not known

, thank you infinitly friend sun .

[sun_2588]

No need to thank, you also helped me frnd....
you dont have to give colon after the ip in ssh.....

so your command sld be...

sudo ssh user@10.100.8.22 "mkdir /home/user/Bureau/new"

this will work...try it..

[Ismatus3]

:) , ok i will try now .

[Ismatus3]

Thank you again sun , i can not not do it , it worked perfectly , i till you my next problem in few time :).

[Ismatus3]

Hello Sun , you know i think that the function :

tkFileDialog.askdirectory()

must show from the begining the network , not only local folders ...
well , your command worked very well , but i can not apply this for python code :

#!/usr/bin/python
#-*- coding:Utf-8 -*-
import os
import time
import sys

source = []
# 1. Les fichiers et repertoires a sauver sont indiques dans une liste.

print sys.argv

for i in range(len(sys.argv)):
          source.append(sys.argv[i])

source.remove(source[0])
source.remove(source[0])

print source
print sys.argv[1]

#source = ['/home/ismail/Bureau/Doc_Unix' ]

# Notez qu'il faut utiliser des double quotes a l'interieur la chaine pour les noms de fichiers avec des espaces.
 # 2. la sauvegarde est rangee dans un repertoire a part.

target_dir = sys.argv[1]

#target_dir = '/home/ismail/Bureau/Testfolder'
 
 # 3. Les fichiers sont places dans une archive zip.
# 4. Le jour courant est le nom du sous-repertoire dans le repertoire principal

today = target_dir + os.sep + time.strftime('%Y%m%d')

# L'heure courante est le nom de l'archive zip

now = time.strftime('%H%M%S')

 # Creer le sous-repertoire s'il n'existe pas

if not os.path.exists(today):
    os.mkdir(today) # cree le repertoire
     
print 'Sauvegarde reussie vers', today

 # Le nom du fichier zip

target = today + os.sep + now + '.zip'
 
# 5. Nous utilisons la commande zip pour creer une archive
 
zip_command = "zip -qr {0} {1}".format(target, ' '.join(source))
scp_command = "scp {1}.zip {0}".format(target, ' '.join(source))
 
# lancement de la sauvegarde

if os.system(zip_command) == 0:
    print 'Sauvegarde reussie vers', target
    
else:
    print 'Echec de la sauvegarde'

Can you explain to me plz , the problem is in line 42 :

os.mkdir(today) # cree le repertoire

, to explain to you more what i am trying to do ; the application create a crontab line like :

00 17 01 30 * python /home/ismail/Bureau/SaveProg/Backup.py  /home/ismail/Bureau/Boulot  /home/ismail/Bureau/Boulot

, it works in locale , and i just need to execute this Backup.py with destination argument in network , so now , i just need to execute this :

00 17 01 30 * python /home/ismail/Bureau/SaveProg/Backup.py  usertest@10.100.8.22:/home/usertest/Bureau/  /home/ismail/Bureau/Boulot

, that will save the folder Boulot in usertest@10.100.8.22:/home/usertest/Bureau/ , and before this Backup.py have to create a folder : usertest@10.100.8.22:/home/usertest/Bureau/20120131 , but this don't work , i can not create this last folder in netwrk ...

[sun_2588]

it is very interesting problem.....if you dont mind me trying this in my own way, by using pexpect and making remote computer password less......it would be a interesting thing to do, that will do for my own, n post here........ this approch i cant able to understand because comments in the problem are in your local language not in english..so if you convert those in english and post here,,,,,

Good morning Sun ,ok , i try to translate :) : this is the new code :

#!/usr/bin/python
#-*- coding:Utf-8 -*-
import os
import time
import sys

source = []
# 1. Files and directories to save are indicated in a list.

print sys.argv

for i in range(len(sys.argv)):
          source.append(sys.argv[i])

source.remove(source[0])
source.remove(source[0])

print source
print sys.argv[1]

#source = ['/home/ismail/Bureau/Doc_Unix' ]

# Note that you must use double quotes inside a string for the file names with spaces.
 # 2. the backup is stored in a separate folder.

target_dir = sys.argv[1]

#target_dir = '/home/ismail/Bureau/Testfolder'
 
 # 3. The files are placed inside the archive zip .
# 4.The current day is the name of the subdirectory in the directory

today = target_dir + os.sep + time.strftime('%Y%m%d')

#The current time is the name of the zip archive

now = time.strftime('%H%M%S')

 # Create the subdirectory if it does not

if not os.path.exists(today):
    os.mkdir(today) # cree le repertoire
     
print 'Sauvegarde reussie vers', today

 # Le nom du fichier zip

target = today + os.sep + now + '.zip'
 
# 5. We use the zip command to create an archive
 
zip_command = "zip -qr {0} {1}".format(target, ' '.join(source))
scp_command = "scp {1}.zip {0}".format(target, ' '.join(source))
 
# start backup

if os.system(zip_command) == 0:
    print 'Successful backup to', target
    
else:
    print 'Failed to save'

You know , till now I could , in a test script , it can create a folder with some name in a distant machine giving like arguments for example : ./test.py user@10.100.8.22 , with this code for example :

#!/usr/bin/python
#-*- coding:Utf-8 -*-
import os
import time
import sys

source = []
print sys.argv
for i in range(len(sys.argv)):
          source.append(sys.argv[i])

source.remove(source[0])
source.remove(source[0])

print source
print sys.argv[1]

target_dir = sys.argv[1]
today = target_dir + os.sep + time.strftime('%Y%m%d')
now = time.strftime('%H%M%S')

if sys.argv[1][0] == "/" :
   print sys.argv[1] + "local"
   if not os.path.exists(today):
      os.mkdir(today) # cree le repertoire
else :
   print sys.argv[1] + "network"
   os.system('sudo ssh %s "mkdir /home/hatim/Bureau/testfolder"' % (sys.argv[1])) 
        
print 'Sauvegarde reussie vers', today

, is it good ? ;) .
