PHPKnock is a web frontend for the port knocking service fwknop . It let you shoot a Single Packet Authorization (SPA) or a port knocking request to any server you configured and ask this server to open a certain port for you or any given IP address.
What is this web frontend good for? You can use it to support any OS or platform that has a browser. E.g. you can install it on an intranet server to open up other servers in your extranet or internet. Another use-case could be to install it in your extranet, so your support staff has the ability to send SPA or port knocking requests from home or somewhere else without installing fwknop to their computer.
- Web server like Apache, Nginx, IIS, or alike
- PHP > 5.3.2 running as SAPI, FastCGI, or CGI
- fwknop client 2.x
Download or clone PHPKnock to your web server. You can put PHPKnock into your document root, but for security reasons, it is NOT a good idea to put your whole Knock directory into your document root of your web server. Instead you should put it somewhere else and use an alias to PHPKnock’s htdocs folder.
Example for your Apache configuration:
"Alias /phpknock /opt/phpknock/htdocs"
For more information visit Apache’s mod_alias.
Copy template configuration file and change configuration as needed:
# cp phpknock/local_config.php.dist phpknock/local_config.php # vi phpknock/local_config.php
Make temporary directory writable for web server user:
# chown www-data:www-data phpknock/tmp # chmod 770 phpknock/tmp
Now you should be able to use PHPKnock thru your web browser. Enter something like
