Hi everyone!
I've temporarily come out of hibernation (and will be gone for about two weeks after this post too) to ask for input on a small PHP script I have just completed.
The script aims to be a remote front-end for Nmap - now for the safety of this post, I ask that any replies refrain from saying anything related to (attack) hacking - god knows Neo's never taken it lightly when a newbie starts spewing his guts (and i'm not challenging his justification - it's his forum, after all).
the tarball is located at:
(i had to make a geocities account for this - it better be worth it! )
i was trying to teach my self bash scripting, just to get a comfortable with it anyway and i wrote a script that uses nmap. its very simple, and the only real thing i learned with it is how to use command line options. anyway it was fun to write and i do use it as an easy way to see if my server is up. right now this script only tests to see if a few services are running, and one fake service just for good measure for my self to see if its working. im gonna add more probably, and try to find a way to remove the dependancy on nmap. its easy to add more, if you want to see it post back and i will post the script. BTW my script has nothing to do with hacking, i just wrote it as an easy way to make sure all services on my server are up.
ah what the hell ill post it. all comments are stripped from the script to save space, everything is very self explanitory as this is very basic.

Credit?! of course! i mentioned in the header of index.php that anyone who contributed would be given proper credit! tell me what you want said! e-mail address, ICQ UIN, url, name, street, phone number, fax, SIN, whatever you want.
While i don't really believe in intellectual property, i *strongly* believe in giving proper credit.
And so does my hybernation begin again - see you in 2 wks... hopefully with your script included.
