I'm looking for what essentially amounts to an "interactive" Wireshark.
I am looking for a tool that allows me to view network traffic on a given port and allow/deny/modify traffic on a per-packet basis. Ideally, the tool could be scripted as there might be a substantial volume of traffic.
It seems that Paros might fit the bill, but it is restricted to HTTP only; I would prefer a tool that is protocol-agnostic. Scapy would be a better fit, but arguably affords too much flexibility -- is there a pretty GUI for it that fits my use case?
Does such a tool exist or shall I have to roll my own?
