In edge-triggered mode, a call to epoll_wait will return only when a new event is enqueued with the epoll object, while in level-triggered mode, epoll_wait will return as long as the condition holds. For instance, if a pipe registered with epoll has received data, a call to epoll_wait will return, signaling the presence of data to be read ...
However, the default connection timeout of Apache httpd 1.3 and 2.0 is as little as 15 seconds [6] [7] and just 5 seconds for Apache httpd 2.2 and above. [8] [9] The advantage of a short timeout is the ability to deliver multiple components of a web page quickly while not consuming resources to run multiple server processes or threads for too ...
When an application closes a socket, only the interface to the socket is destroyed. It is the kernel's responsibility to destroy the socket internally. Sometimes, a socket may enter a TIME_WAIT state, on the server side, for up to 4 minutes. [15] On SVR4 systems, use of close() may discard data.
In the Microsoft Windows and ReactOS [2] command-line interfaces, the timeout command pauses the command processor for the specified number of seconds. [3] [4] In POP connections, the server will usually close a client connection after a certain period of inactivity (the timeout period). This ensures that connections do not persist forever, if ...
Sockets are created only during the lifetime of a process of an application running in the node. Because of the standardization of the TCP/IP protocols in the development of the Internet, the term network socket is most commonly used in the context of the Internet protocol suite, and is therefore often also referred to as Internet socket.
The common default configuration for community strings are "public" for read-only access and "private" for read-write. [8]: 1874 Because of the well-known defaults, SNMP topped the list of the SANS Institute's Common Default Configuration Issues and was number ten on the SANS Top 10 Most Critical Internet Security Threats for the year 2000.

The requested resource is capable of generating only content not acceptable according to the Accept headers sent in the request. See Content negotiation. 407 Proxy Authentication Required The client must first authenticate itself with the proxy. 408 Request Timeout The server timed out waiting for the request.
timeout: Structure of type struct timeval that specifies a maximum interval to wait for the selection to complete. If the timeout argument points to an object of type struct timeval whose members are 0, select() does not block. If the timeout argument is NULL, select() blocks until an event causes one of the masks to be returned with a valid ...
