What is with everyone wanting to know how to bypass their campus security? I'm in college, hell... I spend a fair amount of time in the res. fixing things that guys like you f@#$ up. I used to say, yeah if they wanna do that.. fine with me, i'll ignore it but now it just pisses me off. Why is everyone always so intent on breaking the rules? Use an IM and send the file to your friends, upload it to the webspace that you have provided to you and let them download it directly from there.


Now as to your original, "theoretical" question. Yes it would be possible but there are a lot of ifs. If the webserver has both an associated private and public IP (so that it has access to both networks), if you have the correct permissions on the webserver for the php script to execute all the commands, if you have the knowledge to write a script like that, if your school doesn't monitor bandwidth (if they do... i'd say bye bye network privledges), if you don't mind risking expulsion, if they don't have the greatest security. The list goes on and on. I'd suggest you grow the f@#$ up and find logical ways to do something. Hell burn a CD and mail it to them.

F@#$ing lil kids!
