For most of these troubles, further tools are important. Beneath certainly are a handful of resources and utilities that might help or not less than deliver some clues.
See Wikipedia’s write-up on endianness for information on how diverse CPUs retail outlet byte orderings in memory. When interpreting particular person bytes, this isn’t a challenge.
The TCP4-Hear:8080 and TCP6-Pay attention:8080 arguments tend to be the protocol type and port quantity to employ. They convey to socat to make TCP sockets on port 8080 on all IPv4 and IPv6 interfaces, and to listen to Every socket for incoming connections.
