Re: [Tutor] how to control putty window
Hello,
I've installed Paramiko on my PC with Python 2.7.
My code is:
import paramiko
import os
ssh = paramiko.SSHClient()
ssh.connect('10.10.10.10', username='ufuk', password='ufuk')
But I'm getting this error:
Traceback (most recent call last):
File C:/Users/eufuesk/Desktop/paramiko.py, line 1, in module
import paramiko
File C:/Users/eufuesk/Desktop\paramiko.py, line 4, in module
ssh = paramiko.SSHClient()
AttributeError: 'module' object has no attribute 'SSHClient'
Anybody familiar with paramiko?

But then I want to input new commands to this Putty new window. How can
I do it?
Do you need to control Putty or just SSH to another computer?
If all you need to SSH then I would recommend using a 3rd
party module such as Fabric (which relies on Paramiko). Those modules
will simply SSH significantly. They are Python 2.x but you should
be able to use Paramiko in 3.x except for SFTP. This link might help
to install Paramiko if you are using Python 3.

If you need to control Putty specifically then I cannot help.

What happens if you do

dir(paramiko)
or
help(paramiko)
If those didn't work it suggests the install didn't work properly.
If they do work then I don't know what's wrong.

The problem is that you have a file named paramiko.py in the current directory. When python executes an import, it looks first in the list of built-in modules, and then in a set of directories listed in sys.path. The first directory in sys.path is always the current directory of the script. So when you do import paramiko python looks in the current directory, finds a file called paramiko.py, and imports that happily. The lesson is that you should never give your python scripts the same as a module you're using, because then python will be confused about which file to import, and you'll be confused why your imported module has none of the names it should have.

Looks to me like you're testing it with a script file called paramiko.py So when you import paramiko, it's finding your script instead of the installed paramiko. Even in the best of times, importing a module with the same name as your script is problematic. But in this case, you're completely masking the actual module. So rename your script and move it somewhere other than the desktop.

Re: [Tutor] how to control putty window
It looks like you have named your program paramiko.py? That is hiding the
module.
Try renaming your script.
BTW its probavbly a bad idea to keepm Python scripts on the Desktop.
Better to create a folder.

That said, if you just have a single command, it's simpler to have the ssh client execute it. Get the result using check_output (it sets up and calls communicate): user = 'ufuk' password = 'password' host = 10.10.10.10 remote_cmd = 'r van' cmd = ['plink', '-ssh', '-l', user, '-pw', password, '%s' % remote_cmd] result = subprocess.check_output(cmd, stdin=subprocess.PIPE) I had to add stdin=subprocess.PIPE when trying this interactively. Otherwise plink leaves the console stdin in an unusable state. This is probably the source of the lockup you're getting. If you need an interactive, stateful session, then communicate() won't help since it closes the streams. You'll have to roll your own by manually handling the stdin/stdout pipes. That means you'll need a background thread to get around readline blocking (select only works for sockets on Windows). You'll hit a brick wall with this approach if the program uses full buffering in a pipe. With Linux you can sometimes tweak the streams using stdbuf, but not if the program uses setvbuf(). To get around this in Unix you can use pexpect to fake a tty. I think that's only available on Windows via Cygwin. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

If it's only one or two, you might be able to set up a putty profile with a couple auto-commands on connect, but that's not the same thing. If it's a long string of commands, you might be better to pscp a shell script to the target with one command, and then call that script with the putty profile. I would research automating putty first, then see if there are any options within python to accomplish the same things. -- David Rock da...@graniteweb.com ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
