(PECL)tcpwrap_check -- Performs a tcpwrap check

Описание

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.

Список параметров

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.

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

Примеры Пример 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'); } ?>
