If we had used s.bind(('localhost', 80)) or s.bind(('127.0.0.1', 80)) we would still have a “server” socket,īut one that was only visible within the same machine. listen ( 5 )Ī couple things to notice: we used socket.gethostname() so that the socket gethostname (), 80 )) # become a server socket serversocket. SOCK_STREAM ) # bind the socket to a public host, and a well-known port serversocket. # create an INET, STREAMing socket serversocket = socket. Your browser did something like the following: Roughly speaking, when you clicked on the link that brought you to this page, With INET makes talking to arbitrary machines around the world unbelievably easy With good reason - the combination of sockets They were invented in Berkeley as part of the BSD flavor of Unix. Likely to be other forms of IPC that are faster, but forĬross-platform communication, sockets are about the only game in town. Web server it’s talking to uses both “server” sockets and “client” sockets. The clientĪpplication (your browser, for example) uses “client” sockets exclusively the “server” socket, which is more like a switchboard operator. So first, let’s make aĭistinction between a “client” socket - an endpoint of a conversation, and a

Number of subtly different things, depending on context.

Work with blocking and non-blocking sockets. Try to clear up the mystery of what a socket is, as well as some hints on how to Know what you’re doing (in which case this HOWTO isn’t for you!), you’ll getīetter behavior and performance from a STREAM socket than anything else.

It doesn’t cover the fine points (and there are a lot of them), but It’s not really a tutorial - you’ll still have work to do in getting things This is a 10,000 foot overview of sockets.
