Maximum ports

[Oliver Leitner]

you may exactly open 65535 ports tcp outgoing on every pc with a modern os.

the big question is not about ports

the big question would be, how many paralell connections, or in other words,
sockets are you able to open at once...

these things are given by sysctl parameters for example... there are other
ways too, but thats the most common one...

a hot tip for all ppls who try to program networked tools/programs/libs...

*please* close your sockets, if you no longer need them *explicitely*

Greetings
