Hello I was wondering if someone could explain where I'm going wrong here:
I'm receiving a packet and then trying to send it back out with
self.send_openflow_packet(dpid, packet.tostring(),openflow.OFPP_FLOOD ,
inport)
When I do this I'm getting the following exception:
00290|pyrt|ERR:unable to invoke a Python event handler:
Traceback (most recent call last):
File "./nox/lib/util.py", line 113, in f
event.total_len, buffer_id, packet)
File "./nox/coreapps/examples/aaronswitch.py", line 177, in
packet_in_callback
self.forward(dpid, inport, packet, packet.arr, bufid)
File "./nox/coreapps/examples/aaronswitch.py", line 96, in forward
self.send_openflow_packet(dpid, packet.tostring(),openflow.OFPP_FLOOD ,

return ''.join((buf, self.next.tostring()))
File "./nox/lib/packet/packet_base.py", line 114, in tostring
return ''.join((buf, self.next.tostring()))
File "./nox/lib/packet/packet_base.py", line 109, in tostring
buf = self.hdr()
File "./nox/lib/packet/tcp.py", line 215, in hdr
packet += option.to_bytes()
File "./nox/lib/packet/tcp.py", line 70, in to_bytes
return struct.pack('!BBH',self.type,4,self.val)
TypeError: unsupported operand type(s) for &: 'tuple' and 'long'
Thanks,
Aaron
