This operating system value typically affects Linux and Unix systems. It is important to note that many Unix and Linux installations consider various resources to be ‘files’ including network socket connections. There is a wide range of configuration locations and commands for the various operating systems and versions. In most cases, the settings will be stored in a configuration file in the /etc or /etc/security directories commonly named limits.conf or sysctl.conf. This value may also be affected by the user rights, global system value or a limitation on each open process. Consult your operating system documentation or online sources for configuration details of your server operating system and version.
