Description of problem: From editipsec.py: def on_generateAHKeyButton_clicked(self, *args): command = '/bin/sh' (status , key ) = gtkExecWithCaptureStatus(command = command, argv = [command, '-c', '(ps aux|md5sum;ps alx|md5sum) | tr -cd 0-9 2>/dev/null']) is not even close to being random enough for generating cryptographic keys. Please use something like dd if=/dev/random count=16 bs=1| xxd -ps which should generate a nice random (tm) 128-bit key in hex, which the ipsec code should handle if a 0x is added to the beginning. Or even better, some native python with the same effect :-) The CIPE config part does something similar.
