Mar 14, 2012 · Packet Captures : Wiresharp – CISCO recommends this capturing Tool Span: Instructs a switch to send copies of packets seen on one port to another port. We can connect packet capture device to this other port In large environment, a network capture device connected to one switch might need to capture packets

I did a packet trace (with wireshark) on the ghost server. It appears that the clients query the server with a TCP connection to port 1347 on the server every 20 seconds (heartbeat is set to 30 sec). At each query, the client closes the TCP right after the server sends a packet containing the name of my AI package.

Each host used IGMPv3 to join all 200 multicast groups. Once all joins were complete and the multicast tree was fully populated, we offered 64-, 256- and 1,518-byte frames using a binary search ...
This mechanism helps track network errors or abnormal packet transmission without interrupting the flow of data, allowing ingress traffic (RX mode) to be monitored by a single port that is defined as mirror capture port. The mirror capture port can be any 10/100 port, 10/100/1000 port.
What if you load a linux virtual machine and it becomes a question of how to do it in linux. There is a program called netsed which can change packets, do a find and replace on packets.. so you could stop it that way but would be messy. Or a firewall that lets you specify things within a packet. Linux should have something – barlop Jul 26 '14 ...
