tcpwrap_check

(PECL tcpwrap:0.1-1.0)

tcpwrap_check — Performs a tcpwrap check

Description

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.

Parameters

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.

Return Values

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

Examples

Example #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');
}
?>
