Dave,
Very cool! Thanks for sharing this script.
I am having a problem when the SESAME doesn't contain tcp or udp (or
matches what appears to be the regex for hex).
I modified the script to print some more stuff:
http://etherpad.mozilla.org/RDSg72wbmy
And this is the output:
http://etherpad.mozilla.org/k8gXPyHZdR
Most notably is the system call to echo the $contents to $cmd, where $cmd==''
Any ideas?
Thanks,
Matt
