I use a slightly different approach for starting vpnc-connect if that
will help:
1. have your script create a temporary vpnc configuration file
(including your password):
f1=open('/tmp/vpn.conf', 'w')
f1.write('IPSec gateway ' + vpnAddress + '\n')
f1.write('IPSec ID ' + vpnGroup + '\n')....etc.
2. create a temporary results file, such as f2 =
open('/tmp/vpncResults.txt', 'w')
3. start the vpn client: p = subprocess.Popen('/usr/sbin/vpnc-connect
/tmp/vpn.conf', shell=True, stdout=f2).stdout
4. poll the results file to determine whether or not the connection
succeeded
5. delete the temporary configuration file
Creating a temporary configuration file keeps my password out of clear
text other than for the few seconds the configuration file lives on my
hard drive. In reality, my program runs within the Twisted event-driven
framework, so I just create a deferred object when invoking
vpnc-connect and wait for the callback to see if the connection was
successful, but an earlier incarnation of my program worked with the
above code.
