Zdravim vsechny,
mam maly problem s ukladanim scapy paketu do fronty (multiprocess). Priklad:
from multiprocessing import Process
from multiprocessing.managers import BaseManager
from scapy.all import sniff
class Worker(Process):
'''
Class for sniffing packets, runnig as root
'''
def __init__(self):
super(Worker, self).__init__()
self.iface = ''
self.expr = ''
# key for queue daemon, remotely on localhost:5000
self._keyQ = '10b222970537b97919db36ec757370d2'
class QueueManager(BaseManager): pass
QueueManager.register('get_dataQueue')
self._m = QueueManager(address=('127.0.0.1', 5000),
authkey=self._keyQ)
self._m.connect()
self.dataQueue = self._m.get_dataQueue()
def go(self, iface, expr):
print "Starting sniffer"
self.iface = iface
self.expr = expr
super(Worker, self).start()
def run(self):
print "sniffing ..."
print self.iface
print self.expr
print self.dataQueue
packets = sniff(filter=self.expr, count=10, timeout=10,
iface=self.iface)
print packets
self.dataQueue.put(packets)
print "... done"
But always getting:
Traceback (most recent call last):
File "/usr/lib/python2.6/multiprocessing/process.py", line 232, in
_bootstrap
self.run()
File "/home/tom/web2py/applications/NetSim/DAEMON/Worker.py", line
32, in run
self.dataQueue.put(packets)
File "<string>", line 2, in put
File "/usr/lib/python2.6/multiprocessing/managers.py", line 725, in
_callmethod
conn.send((self._id, methodname, args, kwds))
PicklingError: Can't pickle <type 'function'>: attribute lookup
__builtin__.function failed
PAkety nejsou snad serializovatelne? Nesetkal se s touto chybou uz nekdo
drive?
Diky za rady
