#25602 — Need help connecting via a remote VPN

I need to connect to a site/server that's only accessible after logging into 
a remote VPN, then scan a directory for a file pattern and then copy those 
files.  I know how to do the latter using glob, and I think I figured out 
how to connect to the VPN using win32ras and got a response that said "302 
Found" but I'm not sure what to do after that.  Some people recommended 
using SSH or fabric.api modules, but I couldn't find any examples that 
applied to what I'm trying to do.

Starting a VPN simply makes it possible for IP packets to get to the
specified machine.  You still need to match some protocol that the
particular remote machine can handle.  SSH is probably the most common,
but there are lots of other possibilities, some standard and some
custom.  So the question is what does the remote machine (server)
support for file access?

glob will work if the server supports mounting the remote partition as a
file system.  But there are no guarantees that that's possible.  You
haven't even said what the two operating systems involved are, though I
can guess that the local machine is some version of Windows.

The local machine is running Windows 7.  I'm not sure what the other machine 
is running on, but I assume it can handle ssh.  If it helps, I usually 
connect to it manually via an https web link, and then after entering my 
user name and password in a Firepass session manager it runs an active-x 
cache cleaner program and will then let me navigate to server B which is 
behind the firewall.

If the remote machine is Linux, running sshd, and if you have an account
there, then use scp to copy the file.  And if you want to automate it,
run scp from within python, using the subprocess module.  But make sure
it works manually before bothering to automate it.

To get ssh on Windows, one approach is to install cygwin.

If you want more control than subprocess, there are a whole bunch of 3rd
party ssh libraries for Python.  Just google  python ssh library  to get
at least 6 on the first page.
