tcpwrap_check -- Performs a tcpwrap check

Descrição

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.

Parâmetros

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.

Valores de retornado

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

Exemplos

Exemplo 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');
}
?>
