Main Wippien IP database
is located on this URL (append your JID to it):
and provides IP address to peers. It is your choice if you want to have your own manually set IP, or let use provide one (default).
You can always go to Settings ->Network and choose IP by yourself. However, if you plan to work in open environment, you may want to use IP address someone assigned for you.
Even IP is assigned for you, Wippien
will connect on each session start to see if his environment has changed.
In order to maintain IP address database by yoursef, following requirements must be met:
1. You must have PHP installed on your web server
because it is run as small PHP page. Clean and safe approach.... If you want to translate mediator to something else (such as Python or Perl), be my guest.
2. You must have MYSQL installed
since our script stores information about all IP addresses to simple table.
3. Prepare database
you should create new MYSQL database on your system. You can name it IPS, and create it using following SQL command:
CREATE DATABASE 'IPS';
CREATE TABLE 'peers' (
'IP' int(11) NOT NULL auto_increment,
'JID' varchar(100) collate utf8_bin NOT NULL default '',
'TIME' int(11) NOT NULL default '0',
PRIMARY KEY ('IP'),
KEY 'JID' ('JID')
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_bin;
4. Download script files
You can get script file from here: http://www.wippien.com/download/mediator.txt
Save it to your web server, and adjust following:
$baseaddr = ip2long("220.127.116.11"); // this is class A for IPs
$netmask = ip2long("255.0.0.0"); // netmask for class A
and then in function mysql_connect put your MYSQL details
$link = mysql_connect("mysql_server", "mysql_username", "mysql_pass");
At the bottom of mediator file you should put one or more LINK Mediator IPs.
Using different network range than 5.x.x.x
You can specify additional arguments baseaddr
to URL mentioned above, like this:
if you want to use our mediator for your own IP range. Just put your starting address to baseaddr, and put netmask to 255.0.0.0 or 255.255.0.0 and our mediator will perform
calculations on those values, and provide them to Wippien.
performs actual mediation between peers that want to establish connection. If LINK Mediator is unavilable, you will not be able to connect to any
peer. It is not important which LINK Mediators are used, it is important that both peers use the same one. You can run LINK Mediator on your own computer if it is accessible
by outside peers.
1. Server for LINK Mediator must have public IP address
this is important because all peers must be able to send UDP packets to your mediator on predefined port (currently we use 8000 for LINK mediator)
You can pick mediator script from PHP, C and VB6 version. Pick one from here: http://www.weonlydo.com/VPN/Help/Mediator.html
Here are precompiled binaries - for ones that are not familiar with C++ and compiling, but would gladly run LINK mediator.
If you do run
mediator, and would like to share it with others, please send email to email@example.com
mediator IP and Port and we'll add it to the list.
Having more mediators helps Wippien network being more distributed - so there are no weak links.
