[Tkinter-discuss] ssh login through Tkinter - problem on windows

[Michael Lange]

Hi,

I am writing a small Tkinter app that collects information about incoming
and outgoing phone calls from my router and displays them in a Tkinter
gui. The point is that I want to do a passwordless login via ssh to be
able to see the list of phone calls without having to log into the router.

This works fine on linux, on windows the ssh login works, too, but for
some reason it fails as soon as I open the Tkinter gui.
A minimal example that exhibits the problem:

#########################################

import os, shlex, subprocess, Tkinter

root = Tkinter.Tk()
cmd = '"C:\Programme\ICW\Bin\ssh.exe" -o ConnectTimeout=10 -l root -i "C:\Dokumente und Einstellungen\klappnase\Eigene Dateien\ssh\id_dsa_BS" 192.168.2.1 /bin/bcm_helper -c 1'
#cmd = '"ssh" -o ConnectTimeout=10 -l root -i "/home/klappnase/.ssh/id_dsa_BS" 192.168.2.1 /bin/bcm_helper -c 1'

args = shlex.split(cmd)
pipe = subprocess.Popen(args, stdout=subprocess.PIPE, stderr=subprocess.STDOUT, shell=False)

status = pipe.wait()
output = pipe.stdout.read()

print output# -> the phone calls list as html snippet
root.mainloop()

#########################################

As soon as I comment out the Tk window, the output is printed to stdout as
expected, but with Tk the login fails. I don't know if this has actually
something to do with Tk, though.

Any ideas?

Thanks in advance

Michael
