How fast would one need to allocate ephemeral ports in order to get into the TCP port exhaustion condition?
I was told there are ~4k (older Windows), ~16k (newer Windows) or ~28k (RH Linux) ports available for the client requests. Now, is the pool of port numbers global or per remote IP address?
If they are global, since ports do not become reusable until after 240 (Windows) or 60 (RH Linux) seconds, one would need to allocate them at the rate of ~16/66/466 per sec correspondingly?
Is this correct?
In your experience, is this something I should be practically worried about?
