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 2531. 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');
}
?>
