On campus FTP problems! Admin shut it down.

[ander]

I'm on a UC Campus in Southern California. I'm staying in the res halls and I share a cable modem with my neighbor in the dorms. So my neighbor, he had his IP shut down and he just came in to tell me that he got off the phone w/ resnet saying that they shut him down b/c they detected an FTP on his IP and that it was being used for "illicit purposes". So I guess I jacked him because I registered my hardware to his name since the resgistration saw that we were sharing the same box.

1) How'd they know I was running the FTP
2) Any way for me to get the FTP back up without being caught?

Resnet controls and is responsible for all of the IPs that they distribute. All they had to do is monitor your ports and it would have detected that you were running an FTP site. Even if you switched the ports, a scanner would be able to detect that you had an FTP site up. As for your second question....you don't. Even if you were using the FTP site for legit purposes, if the registration policy says that they don't want you running one, you don't or else they can just block you from getting an IP.

they can easily check and see how many connections are connected to a certain computer. then they can cross reference that with the port number. most FTP's run through port 21. if you set up a new FTP using a different port and limit connections to only a few, you should be good to go.

on our resnet we are allowed to run ftps, but they only shut them down when the user's ftp is using so much bandwidth. once again that goes with however many connections there are.

plus since you were caught once, i wouldnt reccomend putting a new ftp site up.

Man, that sucks. There has to be another way to share my stuff besides FTP.

I been running an FTP for about 3 years now, and I'd hate to have to take it down.

i ran one my freshman year, but then i took it done when i started to notice suspicous connections to it.

i was looking at all the active connections and came across one that was from the domain ".gov". I didnt do anything about it immediately but decided to close it down after a week because I kept seeing various ".gov" connections

Ander, use a program called Hotline. You can run a server and it is similar to FTP and IRC in one nice neat package.

I doubt they will be looking for a hotline server.

Yeah back in freshman year and before napster I was running this huge mp3 site....I was eating up so much bandwidth....it was not even funny....but then I started noticing very odd connections too...and then I got some TXT file uploaded saying that I was getting watched and I should really shut down....but yeah I didn't register the warning and continued on....a few weeks later I got a call from Rescomp and the RIAA saying that there would be a "meeting"....and it all went down hill from there.

All in all try to read up on the University's policy to see if you are even "allowed" to have and FTP site up....cuz maybe you will just be bandwidth limited and not FTP banned.
