Pylibnet 3 comes with some nice features for some quick and dirty scripting. Check out lnsh the new libneterpreter. No need to initialize or import things all the time. The whole environment is set up for you right out of the box when you want to test something quickly. Works in both scripted and interpreter (or command line) mode. Just type 'lnsh' after installing and enjoy the magic. Also, a few significant bug fixes to workaround some libnet bugs. Hopefully the bug submissions will be accepted by the authors of libnet in the near future and all these workarounds will become obsolete. As usual, enjoy injecting and let me know if you'd like to see some more features. Check out the examples as well!
