I don't know exactly what socket means. A server runs on a specific computer and has a socket that is bound to a specific port number. The server just waits, listening to the socket for a client to...
174 I’m running a Debian Squeeze web server. I’ve installed memcached on it, and configured memcached to listen on a Unix domain socket (at /tmp/memcached.sock), as it only needs to receive messages from the website, which lives on the same server.
An endpoint (socket) is defined by the combination of a network address and a port identifier. Note that address/port does not completely identify a socket (more on this later). The purpose of ports is to differentiate multiple endpoints on a given network address. You could say that a port is a virtualised endpoint.
A UNIX domain socket has similar behaviour as a TCP/IP or UDP/IP socket. A socket is bidirectional and can be used by a lot of processes simultaneously. A process can accept many connections on the same socket and attend several clients simultaneously. The kernel delivers a new file descriptor each time connect(2) or accept(2) is called on the ...
When the Client tries to connect to a disconnected IP address, there is a long timeout over 15 seconds... How can we reduce this timeout? What is the method to configure it? The code I'm using to ...
If you're reading this in 2019 and using Ubuntu 16.x or 18.x, especially if you're running multiple IPs, a libvirt/kvm host, or expect that your OpenVPN instance only listen on a single specified port, and are encountering the following error: Socket bind failed on local address [AF_INET]XXX.XXX.XXX.XXX:10e94: Cannot assign requested address All of the other answers are incorrect or poor ...
I've been trying to wrap my head around how sockets work, and I've been trying to pick apart some sample code I found at this page for a very simple client socket program. Since this is basic sampl...
113 A socket is a pseudo-file that represents a network connection. Once a socket has been created (identifying the other host and port), writes to that socket are turned into network packets that get sent out, and data received from the network can be read from the socket. Sockets are similar to pipes. Both look like files to the programs ...
Most socket libraries, however, are so used to programmers neglecting to use this piece of etiquette that normally a close is the same as shutdown(); close(). So in most situations, an explicit shutdown is not needed.
The socket is opened and idle - then keepalive limits are interesting. With an idle socket system will wait tcp_keepalive_time seconds, and after that try tcp_keepalive_probes times to send a TCP KEEPALIVE in intervals of tcp_keepalive_intvl seconds. And only after that all failes the socket times out.
