tcpwrap_check

(PECL)

tcpwrap_check -- Performs a tcpwrap check

Opis

bool tcpwrap_check ( string daemon, string address [, string user [, bool nodns]] )

This function consults the /etc/hosts.allow and /etc/hosts.deny files to check if access to service daemon should be granted or denied for a client.

Parametry

daemon: The service name.
address: The client remote address. Can be either an IP address or a domain name.
user: An optional user name.
nodns: If address looks like domain name then DNS is used to resolve it to IP address; set nodns to TRUE to avoid this.

Zwracane wartości

This function returns TRUE if access should be granted, FALSE otherwise.

Przykłady

Przykład 1. Deny all connections from localhost

If your /etc/hosts.deny file contains:

php: 127.0.0.1

And your code looks like:


<?php
if (!tcpwrap_check('php', $_SERVER['REMOTE_ADDR'])) {
  die('You are not welcome here');
}
?>
