I created a quick backport patch for Scapy 2.2.0 so it could run on Python 2.4. Nothing too special. Just the usual removal of with, try/except/finally and defaultdict.

So if you’re stuck with Python 2.4 like me but still want to [ab]use Scapy, apply the patch and get your fuzz on.

The original ticket is available on Scapy Trac.
