Apache Reference Manual (6)
as a port, the server will listen on the given port and interface. Note that you may still require a Port directive so that URLs that Apache generates that point to your server still work. Multiple Listen directives may be used to specify a number of addresses and ports to listen to. The server will respond to requests from any of the listed addresses and ports. For example, to make the server accept connections on both port 80 and port 8000, use: Listen 80 Listen 8000 To make the server accept connections on two specified interfaces and port numbers, use Listen 192.170.2.1:80 Listen 192.170.2.5:8000 See Also: DNS Issues See Also: Setting which addresses and ports Apache uses See Also: Known Bugs -------------------------------------------------------------------------------- ListenBacklog directive Syntax: ListenBacklog backlog Default: ListenBacklog 511 Context: server config Status: Core Compatibility: ListenBacklog is only available in Apache versions after 1.2.0. The maximum length of the queue of pending connections. Generally no tuning is needed or desired, however on some systems it is desirable to increase this when under a TCP SYN flood attack. See the backlog parameter to the listen(2) system call. This will often be limited to a smaller number by the operating system. This varies from OS to OS. Also note that many OSes do not use exactly what is specified as the backlog, but use a number based on (but normally larger than) what is set. ------------------------------------------------ |
