Problems with running from the module

# --- end sshutils.py

When I run this file from the command line not from the same directory where this file is located it works and the program executes properly. So the module is in:

c:\tmp\ssh-proj\sshutils.py

then I type

c:\tmp\ssh-proj\> python sshutils.py

This is ok. But when I move the file to

c:\Documents and settings\magg\proj\eclipse\py-wksp\unibus\src\unibus\mediators\stdMediators

Then it doesn't work and just hangs on.

In this file I use paramiko and I suspect that there are problems with loading paramiko since it hangs on paramiko getConnection().
