Yeah, i need some help with this too. I've succesfully gotten to the part where you can type in commands.
But what commands exist? I've been searching everywhere and found some video tuts. The guy just type "id" and stuff came up when i did this nothing came up, he also typed "uname -a" and stuff came up ... nuthing when i tried.
But well he used it to put in a backdoor and then wallaboom.
So what commands? |

Maybe you cannot execute commands.  Even if: don't try to tell us you have searched! Just look for linux/unix/windowz commands. I'm sure you'll find something. |

| So some servers do not allow commands? I found some useful pages but still nothing seems to happen. |

And you should be able to let it be.
Or am I talking with a blackhat?!
To topic: Yes, it could be that you cannot execute commands, because PHP could has SAFE_MODE activated or they used the "disable_functions"-setting like it should be. In both cases error_reporting seems to be set off, so PHP doesn't show you any errors. |
