Alright everyone thanks so much for the comments. It reaaly gave me the courage to go ahead and tell the system admin. So what happened is I went and sent him the presentation I did it was like 16 pages power point on how to ARP spoof attack and steal any type of info. After I showed him that he gave me the third degree asking me about why i did it, what i was thinkigng, I told him I was bored and Did it because I knew id be able to exploit it, and He was very impressed, He then asked if i had shared it with anyone which i havent.
I then asked him how he would feel if I continue searching for exploits and he said as long as you dont screw anything up. So anyone have any suggestions the server I'm looking at is behind a firewall all 1000 ports are filtered I have basic services though.

Again thanks again to everyone who answered
