tcpwrap_check

tcpwrap_check

(PECL)tcpwrap_check -- Performs a tcpwrap check

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.

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.

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

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');
}
?>

For more details please consult hosts_access(3) man page.
