Pyrit errors after Dist-Upgrade Fix

I experienced the following error after upgrading my Kali distribution when I tried to run Pyrit:

Code:

---

Traceback (most recent call last):
  File "/usr/bin/pyrit", line 6, in <module>
    pyrit_cli.Pyrit_CLI().initFromArgv()
  File "/usr/lib/python2.7/dist-packages/pyrit_cli.py", line 115, in initFromArgv
    func(self, **options)
  File "/usr/lib/python2.7/dist-packages/pyrit_cli.py", line 163, in new_f
    f(*args, **kwds)
  File "/usr/lib/python2.7/dist-packages/pyrit_cli.py", line 447, in analyze
    parser = self._getParser(capturefile)
  File "/usr/lib/python2.7/dist-packages/pyrit_cli.py", line 179, in _getParser
    parser.parse_pcapdevice(dev)
  File "/usr/lib/python2.7/dist-packages/cpyrit/pckttools.py", line 601, in parse_pcapdevice
    self.parse_packet(pckt)
  File "/usr/lib/python2.7/dist-packages/cpyrit/pckttools.py", line 614, in parse_packet
    if dot11_pckt.isFlagSet('type', 'Control'):
  File "/usr/lib/python2.7/dist-packages/cpyrit/pckttools.py", line 66, in isFlagSet
    return (1 << field.names.index([value])) & self.__getattr__(name) != 0
AttributeError: 'BitEnumField' object has no attribute 'names'

I was able to fix this issue by uninstalling Scapy 2.3.3 that was included in the upgrade and downgrading to Scapy 2.3.2.

You can download Scapy 2.3.2 at https://github.com/secdev/scapy/archive/v2.3.2.zip. Unpack and run the following in a terminal window in the same directory you unpacked the files in (that contains the file setup.py):

Code:

---

sudo python setup.py install

---

After doing this Pyrit ran fine.

Hope this helps.

Thanks for posting the fix :) Was having this trouble with Pyrit, too.

Your suggestion to downgrade Scapy, worked. It immediately fixed the problem with Pyrit.
Thanks!

But now that Pyrit has been updated.... how would I undo the Scapy downgrade?
(And again allow automatic updates from this day forward.)
