ToastGodSupreme Posted July 24, 2003 Share Posted July 24, 2003 (edited) On my previous ISP, I was able to run my FTP server no problem. But I have moved, and now am on a T1 service provided by the apt complex I live in (the servers are physically located a couple hundred feet from where I live {they're in the basement of the main office, which I am right behind} and the cost is only $30 a month). Unfortunately, even though I now have a great upload speed, my FTP is unable to work. Why? From what I was able to get out of one of the techs, they have a firewall blocking all unsolicited trafic from outside their network (1. This is what I am told by two diff techs, 2. this is of course the network which I am on). And since my FTP is listen only, nobody can connect to it. :cry: This, from what I've tried, seems true. My FTP will not function in any mode (PORT or PASV) on any port. It will listen, but not a soul can connect. :no: Is there anyway to get my FTP up and running? :ninja: By the way, I'm using Bulletproof FTP Server. Edit: 21 IS BLOCKED 80 IS BLOCKED 81 IS BLOCKED 1337 IS BLOCKED 2000-2100 IS BLOCKED (there's a pattern here... all ports blocked, ya know?) There was no TOS or Agreement signed when we signed up for the service, nor was there any mention of one. All lines are capped at 100Kb\s DOWN/100Kb\s UP (KILOBYTE! NOT BIT) Edited July 24, 2003 by ToastGodSupreme Link to comment Share on other sites More sharing options...
mm3h Posted July 24, 2003 Share Posted July 24, 2003 have u tryed any different program like for eg ws ftp or cute ftp Link to comment Share on other sites More sharing options...
threetonesun Posted July 24, 2003 Share Posted July 24, 2003 Did you try setting up a HTTP server and having traffic go through that? Not as good as an FTP server, but one of my friends got stuck in the same situation and he found that to be a solution. Link to comment Share on other sites More sharing options...
amoeba Posted July 24, 2003 Share Posted July 24, 2003 have u tryed any different program like for eg ws ftp or cute ftp If the techs are even half-decent they'd just be blocking the FTP port (which is 25 if I'm not mistaken). Therefore you are going to have to use a filesharing type program that works like FTP but does not use FTP. The other option is port spoofing. I have no clue how this works and what program(s) you need to do it. As far as I can gather, port spoofing just edits all outgoing packets and their respective headers. In the header of any IP packet lies a port destination. This port is what filtering software at ISPs are blocking. Did that make ANY sense? ;) Link to comment Share on other sites More sharing options...
Dessimat0r Posted July 24, 2003 Share Posted July 24, 2003 If they've blocked your FTP port, then just set up FTP on another port - your FTP server should have this option. However, you will need to put the port after the URL (i.e. ftp://34.23.444.32:35) Link to comment Share on other sites More sharing options...
rezza Veteran Posted July 24, 2003 Veteran Share Posted July 24, 2003 didn't you guys read his post? he's already tried on other ports. so running a http server probably won't work, becasue its basically the same as ftp on port 80 (with a slightly different protocol), but who knows, maybe they'll let port 80 slip past. worth a shot i suppose. and it appears the techs aren't just blocking the ftp port (which is 21 by default by the way) because he's already tried others.

+BudMan MVC Posted July 24, 2003 MVC Share Posted July 24, 2003 If they are blocking inbound traffic - there is nothing you can do. You need to find the ports that are open inbound. And listen on that port. Or ask them to open ftp up for your IP. Does their AUP state that you can NOT run a server? Since you state they said that they are block almost all inbound ports, I would guess the running of servers is against their AUP? Link to comment Share on other sites More sharing options...
ms998 Posted July 24, 2003 Share Posted July 24, 2003 Theres prob a good reason why it would be blocked, eg share of bandwidth for evryone. Your best bet is to possibly speak to the techs and see if they can allocate you a share of the bandwidth Link to comment Share on other sites More sharing options...

Yeah, it seems like port 80 is open more often than 21. I mean, letting someone set up a HTTP server on your line is one thing, letting them set up and FTP server is another.

SunnyB Posted July 24, 2003 Share Posted July 24, 2003 If they are blocking all inbound traffic you will not be successful. Get a port scanner and scan the network to find an open (listening) port. Set your server to listen on that port. If running a server is against their TOC / AUP they will most certainly find out and probably boot you. Not good if this is your only internet option.

ToastGodSupreme Posted July 24, 2003 Author Share Posted July 24, 2003 Updated my post a little. Thanks for the ideas so far, I've emailed one of the office staff about whether or not there was a TOS. But we were neither given one nor informed of one.

John Veteran Posted July 24, 2003 Veteran Share Posted July 24, 2003 just change the port the ftp server uses to 22 or something, and then have everyone connect to the url ftp://192.168.0.1:22 (replace 192.168.0.1 with your own ip). my isp is similar, they block 21, 80, and a bunch of others, but i can run an ftp, web server, whatever i want (except AD, no domain :cry: ). thing is, i have a low upload speed (128kilobits/s compared to my 1.5mbit down) so it's kinda pointless.

That was their solution instead of blocking ports, I guess. Link to comment Share on other sites More sharing options...
spacey Posted July 24, 2003 Share Posted July 24, 2003 try Open WebMail, it has a file sharing thing so you can get access to your files w/o an FTP and even behind Proxy/Firewall... all you need is the ability to browse :) Link to comment Share on other sites More sharing options...

SunnyB Posted July 30, 2003 Share Posted July 30, 2003 If you are paying $30 per month for shared bandwidth with x number of users you might be better off getting your connection from your local telco. Or possibly contacting another provider in your area. If your current connection is your only option you should probably just accept it. If one of your neighbors was running an FTP server on a shared bandwidth line and it restricted your bandwidth to 56K or less, how would you feel about it? Or if you were in a download and got kicked because your transfer rate dropped below the minimums, how would you like it? Get another provider or live with it.

Fred Derf Veteran Posted July 30, 2003 Veteran Share Posted July 30, 2003 Here is a list of common port numbers http://www.iana.org/assignments/port-numbers I doubt they have blocked everything. Some must have legitimate usages. Some programs like ICQ require ports to be open to function fully. Obviously Kazaa and the like do but I can see how they might WANT those blocked. Try running your FTP server on port 4000 (assuming you don't use ICQ). Link to comment Share on other sites More sharing options...
mgicash Posted July 30, 2003 Share Posted July 30, 2003 Everything cant be blocked. If everything was blocked you would not be able to surf the internet....port 80 may be blocked but you are getting internet through a different port that is open then, so find out what port that is and host your ftp server on it. try 8000 or 8080 i have seen many admins use these ports instead of 80 Link to comment Share on other sites More sharing options...
Lomex Posted July 30, 2003 Share Posted July 30, 2003 They can block every incoming port and he'll be able to surf the web, download, etc etc.. Why? Because if they set it up right, when you inisiate the connection to the source, that port is being opened on the router. This allows for traffic flow. In his case nobody can connect to his box because the router just drops the connection. If they wanted to, they could as well block outgoing ports for apps like kazaa for example. So if they do that, just save yourself the frustration and get your own internet connection. Link to comment Share on other sites More sharing options...
mgicash Posted July 30, 2003 Share Posted July 30, 2003 yes lomex your right, sorry I didnt clarify. In his original post he mentioned something about all ports being closed, so I was just telling him that all coulndt be closed....I meant to imply that outbound ports had to still be open to surf web etc...they could have just not opened any inbound ports....but not likely.

Lomex Posted July 30, 2003 Share Posted July 30, 2003 From what he's saying it seems that's what they did, closed all inbound ports.. That way he won't be able to run any type of a server... Conserve the bandwith, since this connection has to be good enough for everybody in the building... Link to comment Share on other sites More sharing options...
