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'); } ?>
