Folks:
I am a Network Engineer, but have been trying to teach myself Python since
Cisco will be leverage it on new high end models, yet I am very new to

traffic, more specificity multicast packets from a few sources
Dear all
I have a problem with multicast sockets of the same port but belonging to
different groups.
For example, I have two udp sockets, listening on the same local address and
same port; for each one I set the sockopt to listen on a specific multicast
group (I can also see the igmp packets
EADDR,1)
#The sender is bound on (0.0.0.0:1501)
self.sock.bind((ANY,SENDERPORT))
#Tell the kernel that we want to multicast and that the data is sent
#to everyone (255 is the level of multicasting)
self.sock.setsockopt(socket.IPPROTO_IP, socket.IP_MULTICAST_TTL,
25

I'm trying to get a simple multicast application working using
Twisted; so far I have:
from twisted.internet.protocol import DatagramProtocol
from twisted.internet import reactor
from twisted.application.internet import MulticastServer
class MulticastServerUDP(DatagramProtocol):

in specific conditions, e.g.
when the network or one of the communicating computers is overloaded,
you can loose packets or
receive them in the wrong order.
So, first of all, if you cannon tolerate packet loss, consider
switching the protocol to TCP.
If you cannot chan
Hi all,
I have a question about python and sockets , UDP datagram in
particular. I'm new to socket programming so please bare with me.
I am trying to write a simple application that broadcast files to
another computer on the same network/subnet but I do not want the
receiver computer to have to r
