Greetings for The Community.
This will be a bit apart from Wireshark itself but I haven't found a
better place to start.
I need to communicate with a device in LAN and to perform some "standard"
operations using tools like curl, telnet (possibly with Expect) or any
other typical tool. That's elementary.
But, to increase efficiency of the entire process, I'd like to communicate
simultaneously with many devices that have a distinct MAC address BUT the
same IP address - like performing software upgrade for many devices of the
same kind and at the same time using only a single PC machine.
I came to an idea that this is doable but there's a need to create a some
sort of a framework that can be launched in a few instances (or using a
script) and will take care of delivering frames with a particular source
MAC address to particular child processes and also, for that child
processes, replace a standard ARP table with a "local" ARP table attached
to that child processes. For a single instance, a single IP to MAC mapping
would be enough.
In this way, a single PC could communicate with many devices and above
mentioned child processes would not spot any difference (on OSI L3), so
those could be any "standard" networking applications.
I've been crawling the Internet looking for tools that would suit my needs
but apparently there's none. Unfortunately I'm not that skilled to be able
to create it from the scratch, so I've been hoping that someone could
point me to the right direction - how to approach the solution and what
kind of tools would be the best to fulfil it.
Or maybe the way I look for is wrong and there are some better than mine.
