Beschreibung

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.

Parameter-Liste

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.

Rückgabewerte

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

Beispiele

Beispiel #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');
}
?>
