What is the theoretical maximum number of open TCP connections that a modern Linux box can have
...
If you used a raw socket (SOCK_RAW) and re-implemented TCP in userland, I think the answer is limited in this case only by the number of (local address, source port, destination address, destination port) tuples (~2^64 per local address).
