Other interesting Mac alternatives to Advanced Port Scanner are Angry IP Scanner (Free, Open Source), WakeOnLan (Free), ZMap (Free, Open Source) and iNet - Network Scanner (Freemium). MORE APP INFO Alternatives 7. In case you need just the network scan feature of iNet Pro, use the free version iNet - Network Scanner. You can always update to iNet Pro from within iNet to access its full feature set.
Sockets¶
I’m only going to talk about INET (i.e. IPv4) sockets, but they account for at least 99% ofthe sockets in use. And I’ll only talk about STREAM (i.e. TCP) sockets - unless you reallyknow what you’re doing (in which case this HOWTO isn’t for you!), you’ll getbetter behavior and performance from a STREAM socket than anything else. I willtry to clear up the mystery of what a socket is, as well as some hints on how towork with blocking and non-blocking sockets. But I’ll start by talking aboutblocking sockets. You’ll need to know how they work before dealing withnon-blocking sockets.
Part of the trouble with understanding these things is that “socket” can mean anumber of subtly different things, depending on context. Coda 2 5 12 download free. So first, let’s make adistinction between a “client” socket - an endpoint of a conversation, and a“server” socket, which is more like a switchboard operator. The clientapplication (your browser, for example) uses “client” sockets exclusively; theweb server it’s talking to uses both “server” sockets and “client” sockets.

Of the various forms of IPC,sockets are by far the most popular. On any given platform, there arelikely to be other forms of IPC that are faster, but forcross-platform communication, sockets are about the only game in town.

They were invented in Berkeley as part of the BSD flavor of Unix. They spreadlike wildfire with the Internet. With good reason — the combination of socketswith INET makes talking to arbitrary machines around the world unbelievably easy(at least compared to other schemes).
