I must say i'm impressed on this small utility (PHP Shell). It's a PHP scripts, but it a tool you can use to execute arbitrary shell-commands or browse the filesystem on your remote webserver. This replaces, to a degree, a normal telnet connection, and to a lesser degree a SSH connection.
It will shows a forms that can be used to login and execute several commands in your servers via your web server web interface.
Installation is very simple. All you need is unpack the package and place it on a directory where you can access it. Next thing is generate a randomize password using the password generator provided and put it on the configuration file and you are set to go.
It has some limitations though, for example not working when Safe Mode is ON, can't be used to run an application and it can't receive user input after it has been launched. So basically, you can do all administration stuff, but you can't run an application with this utility. Nevertheless, it's still a simple and useful scripts. Great job Martin
