Open FTP behind behind college network?


Recommended Posts

Hi all, I finally got into the college I want and now living in a dorm ;)

Since I'm behind my college's firewall, is there any possible way to open a public ftp (or other means to connect to my comp/hd) so I can grab files while I'm at home during the weekends?

Oh btw, I'm not stupid enough to ask my college's sysop to port forward 21 to my machine in dorm :p

do u have a router?? i run KDX ftp server and it works fine i just open up a random port and have that forwarded to my computer and i know a friend that runs bulletproof ftp just as well with no problems even though i have a router i have to run it with a static ip so i can forward it to my ip address

but wouldn't all public requests to your router come via port 21? or are you telling users to connect via a different port that your router than redirects?

well i dont think the sys op like that kind of things u can try raidenftp and maybe on a other port but i doubt u can. on my school they hate every thing not related to school. what u can do is to get a USB memory stick. we have to have 1 on school. we put our files on it and go home. very easy couse its like a big floppy the 128 mb are about 50 euro so not that expensive.

one of the greatest inventions next to the cd-r.

yes u would have to specify in your ftp program the use that port that u opened in your routor u dont have to use port 21 that is the most common port that it is set to it doesnt mean you have to use that port to run the ftp u can use any port u want u just have to specify it in your settings

OK GUYS, he will not be able to forward his port to his machine because he is on a SCHOOLS NETWORK. The only way to get the FTP server to work is if you get the Sys Admin to forward the port for you, who will probably not every happen.

YES HE CAN ........im in the dorms at my college i am running a linksys router i run static ip with my router connected to the college network all i did was open a port in my router and when my users connect they specify their client to ftp to that port using my wan ip and then my router forwards that to my machines ip behind my router i didnt have to get anything from sys op on campus

Exactly my point.... you were given a static IP. He has a PUBLIC IP address. Unless he gets the admin to forward the port, or he gets a STATIC IP, it can not be done.

This is my ipconfig info, my comp is connected directly to the wall, with no router in between.

Connection-specific DNS Suffix . :

IP Address. . . . . . . . . . . . : 128.208.44.57

Subnet Mask . . . . . . . . . . . : 255.255.255.0

Default Gateway . . . . . . . . . : 128.208.44.100

I'm guessing this is my internal lan ip, but many websites such as http://www.whatismyipaddress.com/ also shows 128.208.44.57 as my (public?) ip.

And please help me define the terms "static/public" ip that you guys were talking about.

Thanks :)

Thanks for the idea, but sometime i prob. will want to grab large files :shifty: :shifty: , so usb/cdr aren't the most effecient solutions to my problem.

Plus I would like to know how to setup ftp behind college firewall :)

So you go to the University of Washington. I agree with dougkinzinger, if inbound is blocked by the school - not going to happen without school admin help. Would you like me to email them, giving your ip address and time of request to bypass their security?

BTW - the discussion of circumvention is against neowin rules, is it not? I would consider asking how to bypass your schools firewall circumvention - wouldn't you? ;)

edit: Here - since you must of missed it somehow?

Rules For Computing and Networking in UW Residence Halls

You MAY NOT use network connections in UW housing to provide any service that is visible off campus (i.e., available on the global Internet). This applies to services such as, but not limited to, HTTP (Web), telnet, FTP, IRC, and email. (Note that you MAY set up public services visible off campus using the servers provided on the C&C Uniform Access computers, provided your use complies with C&C guidelines.)

Seems pretty clear to me that the running of a FTP server visible to OFF campus - ie the public net, is kind of against the rules of UW - unless the machine your talking about is one of these C&C Uniform Access computers? The ip address you posted does put you on the UW campus.

haha thx budman, didn't notice that rule :p but my intention isn't to open a public ftp, but a private one that only I am accessible, but it's still consider a public one since I'll be outside the campus...

It's alrite budman, don't really wana get expell for doing this kind of things :p

Although, I'm interested in how to bypass the security. I just to expand my knowledge in networking.

A better idea would be to set up an FTP server off-site (like using geocities for their free space without making a web page, for example) and upload stuff to there and have your computer automatically sync itself on a regular basis so that it will download whatever you upload.

why don't you just give it a shot.... get a ftp server (such as serv-u) and use a port other than 21 (since it's almost guaranteed to be blocked by your university).. use like port 7495 or something ... then have one of your friends try and access it... when accessing have them put in the ip address:port number .. so let's say 128.208.44.57:7495

sounds like someone wants to be shareing more then personal files if you have such large files... unless your doing digital video productions, i doubt you have a need for such "large" files to be transfered

Very valid discussion reasons. You can not secure something, if you can not figure out how to get around it - But these types of topics are not really suited for neowin ;)

In reading the rules for UW, they do mention that they are blocking normal ports - that would be used for servers from the outside. From the way I read the rules - you can setup servers - but only for other UW machines, ie most likely the next dorm room will be able to access your ftp server.

The way I read the rules, they do provide servers you could setup this type of thing. So that you could store files there - that you could access from outside UW (from home, etc) As long as the files be made available to not break any of their other copyright rules, etc..

I am all about learning and securing, etc.. And there is always away around :) But I would suggest you get with the Admins - tell them what you want to do, I am fairly sure they will provide you will a means to accomplish what you seek (access to your files, when not on campus) to do - without breaking any UW policies.

Yes I think they do provide students space to store file them to access while outside the campus. But I haven't explore into that direction yet since I heard it's only 500mb. So far i'm just curious about the possibility of opening a public server inside school network, and it is not important to me since I have my own ftp/space outside the school network.

I'll try to open a ftp like schwarz2 suggested, but I'm pretty sure the successful rate is extremely slim.

Btw, bittorrent/kazaa/directconnect works (both ul/dl) here, maybe I can look into them as possible transfer mediums.

UW poilcy

no ftps open to the public allowed.

actually, does 128.208.44.57 looks like a public ip to u guys? if so, does that mean my college is actually an isp?

Yes its a public/routable IP address! And yes since your school is providing you with internet access - so I guess you could call them your Internet Service Provider. What does that have to do with anything??

BTW - the entry requirements for UW must be quite slack, since its plain you can NOT read with any level of comprehension?? The rules of your school PLAINLY state that you can not provide access to the OUTSIDE world from your dorm room. And that they do provide you with machines that you can do that from - if needed.

You complain that they limit you to 500MB - I find it hard to believe this would not be enough space for any legit use of the service. The school rules also make it PLAINLY clear that the sharing/storage/xfer of copyrighted material is in VIOLATION of policy.

I do not go to this school - nor have I ever gone to it - and I found the school policies in a matter of a couple of minutes. I am almost 100% sure that when you moved into the dorm - you were presented with these policies. And most likely signed some agreement stating you would follow them.
