[Tutorial] Get P2P Working behind a Firewall

[alib_i]

Your Freedom is very good .. everybody who has used it says that. Somehow it never worked for me. Tried everything I could, but never clicked. So, I wrote about what I could write . HTTP-Tunnel, it seems, has recently put a speed barrier (earlier the paid service only offered paid servers, which were less clogged).

Emule .. again .. never worked for me, so not in a position to write about it. If you can, write a proper tutorial, I'll patch it up in the first post.

and moshel .. look for somewhere you can put in "socks proxy" .. when you find it .. put in 127.0.0.1 as IP and 8080 as port.

your-freedom is the only one which works here. Because the initial URL is from https source and hence it isnt blocked. Also I dont need an installer for it as I can run the java version of it. All this make it the most viable solution if you ask me.

alib_i..
Its a good turorial but its not working for me. Please help me. I am behind firewall/proxy . Though i can access any web site(http) and download any thing but this p2p is not working as only port no. 80 is open. I can access https site also. Let my proxy is x.y.w.z then how can i use sockscaps , bittorrent client please give me step by step guide. Bittorrents log is given here :
[2005-12-01 01:29:14] -- BitTorrent started --
[2005-12-01 01:29:15] "AbarAranye.avi" : This torrent (or one with the same contents) is already running.
[2005-12-01 01:29:16] (global message) : Could not get latest version from http://version.bittorrent.com/win32/stable
[2005-12-01 01:31:52] "AbarAranye.avi" : Problem connecting to tracker - <urlopen error (7, 'getaddrinfo failed')>
[2005-12-01 01:32:50] "AbarAranye.avi" : Problem connecting to tracker - <urlopen error (7, 'getaddrinfo failed')>
[2005-12-01 01:34:50] "AbarAranye.avi" : Problem connecting to tracker - <urlopen error (7, 'getaddrinfo failed')>

looking forward ...

Is there a software like HTTP-Tunnel for mac?

[alib_i]

shersaha,
I would suggest .. use BitSpirit (link given in last page) and you can forget about SocksCap.

Setup HTTP-Tunnel (or YourFreedom or any similar softie) .. configure your w.x.y.z proxy in it..
and specify socks proxy (127.0.0.1:1080) in BitSpirit.
This combo gives best speed (atleast for me)

As for your log ...
I think either your tracker is down, or your HTTP-tunnel (or whatever) not connecting ..

Post here if you have any more problems ..

PS: It's possible that your proxy server has blocked tunneling ..
It's done in a few proxy servers at my place

[shersaha]

alib_i,

will try tonite and see what happen... is there any way to test whether my proxy is blocking tunneling or not?

[alib_i]

I generally use desproxy for such testing ..
It's a command line socks sever ..
If it gives replies such as "access denied" ( and a HTML code for a webpage showing this access denied info ), then I can be more or less certain that tunnelling is blocked on that proxy.

[shersaha]

I have already downloaded desproxy. But could not know use. please tell me how it works...

I have following :
1.desproxy
2.desproxy-dns
3.desproxy-inetd
4.desproxy-socksserver
5.socket2socket

now tell me how to test whether proxy is blocking tunneling or not?

How can I test what port is open or not ?

Please tell me details procedure..

[alib_i]

hmm ... this is something I do myself ..
It may not be right .. I have no idea if it really works the way I think or not.

that was the disclaimer

.. anyways ..
You need the file desproxy-socksserver ..
# Open command prompt ..
# Navigate to desproxy folder
# Run the file desproxy-socksserver .. using following parameters ..

C:\>desproxy\desproxy-socksserver proxy-ip proxy-port local-port

# local-port is usually 1080
# You need to find out which port is open in the proxy yourself. I cant help you there (you can use programs like BluesPortScanner to find open ports, but it's not that useful)
# Run your P2P application.
# Now if you see a reply similar to this pic .. then most probably your proxy has tunnelling blocked



(can somebody verify this trick ?)

alib_i,
thanks for reply. what I found reproduced below..
I have start desproxy_socksserver proxy proxy_port local-port(1080).

Result is: TCP port 1080 bound and listening
press <ctl+c> to Quit.

scanned the port using blues portscanner.. result is not understandable -- like this--[7-echo],[21-ftp],[80-www-http],[1080-socks] like this. Now tell me whether this port is open or not?

Now I have started Bit Torrent client and setting in network is like this-- starting port 1080.

but there is no error message like you have shown in image.. If I am wrong please corect..

Can you give me step by step procedure so that it will help me better..
Advance thanks for your reply

ps: one more thing pse tell me how I will have to take screen short and publish in forum so that who help me(lik u) can understand the problem easily.

[alib_i]

sorry for the late reply .. i was at home .. (no free net there )

back to topic ...
I think you've ignored one of my previous replies where I asked you to dump BitTorrent client ..

So, here's the procedure

# Download and install BitSpirit (the link is in 1st page of this thread)
# In BitSpirit .. go to Options-> Preferences-> Proxy and NAT Transversal
# Press 'Add' and enter following details
name = <anything you want>
server = 127.0.0.1
port = 1080
proxy type = SOCKS5
timeout = 12sec (or any such no.)
Check the box 'let proxy resolve host name'
Leave 'proxy auth' part blank
# Now start desproxy like the last time ...
you'll get this message

TCP port 1080 bound and listening
press <ctl+c> to Quit.

It means that the socks server is up and running ... dont close the window .. let it run
# Start the torrents in BitSpirit.

That's it ... as simple as that.
If you still have doubts .. I think you better call any of your friends to help you. I cant specify each and every small detail in writing.

about Bluesportscanner

--[7-echo],[21-ftp],[80-www-http],[1080-socks] like this. Now tell me whether this port is open or not?

All ports you see in that list are open ports.
ie. port 7, 21, 80 and 1080 are open .. others are closed
BluesPortscanner writes some info about the open port ..
like port 21 is generally used for ftp .. so it writes '21-ftp'
port 80 is usually http port .. hence it writes '80-www-http'
you can promptly ignore these extra words ... port 7,21,80 and 1080 are open
but it doesnt mean that there is a proxy server running on each port .. it just means that they're open .. for one reason or other.
(that's why i said in last post... it's not that useful)


about screenshots ...
Press 'PrintScreen' button on your keyboard to catch the screenshots
Open 'paint' from start menu and paste it there .. Save it as .jpg
Upload the image in any popular image upload site like http://imageshack.us
(Alternatively you can press ALT+Printscreen to take a screenshot of only the active window, like I did for that screenshot)

I hope I answered all questions..
Best of luck

thanks for reply. Its late reply as i am on leave. I understand your time constraints. however you have devoted so much time and thanks for that. sorr for wasting your valuable time. I willl try you suggestion ..

[netcracker]

I was using http-tunnel but it is slow.....so i used your freedom and it is realy good...i get realy good speeds..but the problem is that it disconnects after 120 mins is ther any workaround this problem?
or atleast somesoftware or program that will reestablish connection?

I tried desproxy.....but it is bloacked

Also are there any other programs other then that you have mentioned???

[netcracker]

Also I was tring Ragnarok but it is not connecting......do u guyz know how to get it to work........it is just not connecting

[demonsnake]

Hey fellows... i am college student and put up in university hostel. Lately our IT guys have put an annoying proxy cum firewall called Firewall, its a HTTP based service. This has been blocking everything ranging from downloads, porno, games messenger.

I haven been using YOUR freedom for casual web surfing and lil downloading. Few days back i installed HTTP Tunnel, but i don;t know how to use it.. i was ablr to configure it but none of applications seems to tie up and work with it.

MY HTTP Tunnel say:

<>HTTP-Tunnel Client v 4.0.3065
<>Starting HTTP Tunnel, waiting for Client to Connect
<>INIT: Successful
<>Retrieving HTTP-TUnne; server's IP address, please wait
<>Please do not start any application until this is complete
<>RetrieveIP: Using free server #1 [209.8.4.133]
<>IP address succesfully retrived
<>RIP: Using Proxy mode
<>SOCKS 4/5 server succesfully started

as i said i AM able to resolve connections, suppose i would like Yahoo Messenger to use HTTP Tunnel/s SOCK 4/5 Capabilty.

So i open up Yahoo, and in connection preferences i select SOCK 4/5 Proxy, give address as 127.0.0.1 port 1080.

NO LUCK... NOTHING WORKING

My main aim is to use THIS TUNNEL THING WORK WITH KAZAA. pLASE helP...

[anshul]

Though I am a member of this community..............I didn't ever notice this tutorial. I scavenged the net for solutions and had a lot of success. So I would mention some problems and some more solutions for this discussion.............

Firstly
HTTP tunnel is not free..........the one that is free has very less speeds.
I am yet to use socks cap.............

Now for the methods.................



FOR ALL YOU FTP FANS

USE TOR NETWORKS, If your institute has good broadband connection............

You will get very good download speeds from FTP servers. I use TOR+FILEZILLA as flashXP is not free.
(*This will work even for torrents but I urge you not to do it as it unnecessarily burdens the TOR network.If they can respect your desires then you must also respect their's).



Your Freedom free account doesnt allow 64 KBps(kilobytes per second) but 64 bits per sec which is around 8 bytes per sec. But it is still a good solution. So use it..........

I am using both..




There is a online bit torrent client on
http://www2.torrelay.com

it downloads on its servers for you from where you can download it as a normal download. Unfortunately free users have only 3 slots(maybe they decrease it on future)per day and the download from their servers is slow.........does not support resume and is unpredictable for free users.

As of now I am not satisfied with the speeds and am researching more..



Keep each other informed of the latest developments and have fun.

Nice article.Thanks for the information.
