NTL blocking BitTorrent ports? (6881 to 6889)
 
I'm a BitTorrent user (BitTorrent is a P2P program for those who don't know what it is). In the last few days my BitTorrent download speed has gone down dramatically (I'm on the 600k package). After a bit of investigation I discovered the abysmall download speed was due to incoming connections from peers being refused (because somehow ports 6881 to 6889 were blocked). I initially thought I had misconfigured my software Firewall ZoneAlarm but it turns out the problem still exists even when ZoneAlarm is not running.
As I used to be able to accept incoming peer connections I can only deduct NTL has recently decided to block ports 6881 to 6889 to prevent users from achieving proper download speed with BitTorrent.

Has anyone else noticed this problem? Can anyone confirm those ports are indeed blocked by NTL, and can we ever expect these to be unblocked?

i too have experianced a slower to zero download speed thats without upload saturation i do get connection refused errors sometimes

I've not had any problems with it.

Re: NTL blocking BitTorrent ports? (6881 to 6889)
 
LOL, another one.

NTL are not blocking any ports other than the ones listed in thier original article, but just to allay your fears I have just spent nearly 15 mins testing the ports you mention both in and out of the NTL network [to various other networks I have access to] and they all work perfectly.

FYI - ZA has a habit of screwing your network even when you think it is turned off (even when you think you have uninstalled it !!).

Agreed. I've had to reinstall windows before now just to get networking working again. Although, to be fair, I suspect this has more to do with windows being a bag of s***e than zone alarm (as i understand it, za has to plug into windows at a lower level than apps are supposed to just to provide the functionality that should be provided as standard by ms)

Dont use Zonealarm, its famous for doing that, its done that every time ive ever installed it, its worked fin for a few weeks then bang, my internet would behave poorly.

I use Sygate Personal Firewall now and ive never had a problem with that. Touch Wood

SuperCow 06-12-2003 23:35

Re: NTL blocking BitTorrent ports? (6881 to 6889)
 
Thanks for the replies. I'm more than willing to accept the problem is due to some software misconfigurations rather than NTL's fault. I'll try uninstalling ZoneAlarm completely to see if this fixes the problem. Note that BitTorrent *is* working though, it's just the D/L speed that's suffering due to peers being unable to connect.
The BitTorrent client at http://bt.degreez.net/ tells you when you're not accepting peer connections by switching the status LED colour to yellow (instead of green).

Out of Interest Supercow - what routers/pop site are you going through? you can find this out by running a trace and finding out what the router called xxxx-t2core-a...blah...blah or xxxx-t2core-b..blah..blah

SuperCow 09-12-2003 23:57

Re: NTL blocking BitTorrent ports? (6881 to 6889)
 
I resolved the problem btw - it was due to user incompetence!
With all the recent DNS problems with NTL I had enabled a transparent cache in the proxy server settings and "forgot" it was there. Having a proxy server set up was causing incoming BitTorrent connections to be refused. I had read that some ISPs were blocking ports used in some P2P programs so I jumped the gun and wrongly assumed poor'ol NTL was doing this!
Thanks for all the help.

philip.j.fry 13-12-2003 15:25

Re: NTL blocking BitTorrent ports? (6881 to 6889)
 
Sorry to bring this up again but I am very suspicious of NTL attempting to do something to minimise use of BT.

On thursday, I was downloading through BT at near capacity not using the default ports, then my modem went offline, when it came back up dl/ul were reduced.

Starting a new BT download today, I couldn't make any connections at all, until I shifted the listening ports away again, now speeds are back up quite high. It does seem highly suspicious.

Fantastic! This problem has been driving me mad. I was pretty certain that the ports weren't blocked by NTL or my firewall as I could telnet to them from outside the NTL network... It never occurred to me that bittorrent would use the proxy settings from Internet Explorer (or is this just another example of how IE is intimately linked with Windows, despite the court rulings?). Thanks SuperCow!

Hallo all!

Ok, just out of interest here, I have assumed of late that the world of filesharing was just going downhill. To me, getting a full download rate is just laughable. I, on average get around 2-3kb/s no matter what I use. Normally use Kazza Lite but have since tried just about everything else under the sun, including BT, DC++, Shareazza, Limewire, you name it, I've tried it. But everything I try is just pants! Time to download an (out of copyright! :) ) mp3 - 6 years and 31 days!

I'm using a cable modem which is connected to a linksys router (the 4 port one with 41 at the end of the name). I remember the halcyan days of getting 50/60 kb/s, but can't remember if this was only on ADSL. Am I missing something here? Thanks guys! (I lurk a lot but am a shy type!)

P.S. the Shadow's BT client is always on Yellow and this is apparently a bad thing. I'm not running a firewall, windows or otherwise.

SOSAGES 12-01-2004 22:52

Re: NTL blocking BitTorrent ports? (6881 to 6889)
 
well if ur torrent client is showing yellow that normally means its behind a firewall that needs ports 6881-9 open

if u connect through a router thats your problem
if yoru running windows xp and that firewall is on then thats ur problem ..

other than that id ask u sure you dont have a firewall on :)


www.grc.com take the shields up test and see what it finds

SOSAGES 12-01-2004 23:02

Re: NTL blocking BitTorrent ports? (6881 to 6889)
 
oh u are behind a router..

right well u need to have a quick lesson in port forwarding :)

its in the manual and pretty easy you want ports 6881-6889 i think (as torrent will use 6881 and if thats being used will move on till it finds a suitble one) if u want in shadows client u can edit the ports to something else of your chosing

anyway dunno what router you have (it has a 41 in it)

but:
http://www.linksys.com/support/top10...%20BEFSR41.asp

or for the other router i found with a "41"

http://www.linksys.com/support/top10faqs/BEFSX41/ have a read of the port forwading/trigger


torrents good but i recomend emule

(that uses port 4662 + 4672) and have a browse of sharereactor.com the emule web site offers a load of help so you cant go wrong or pm me i will help ya

It must be your settings - I use BT, and i'm on the 1Mbit package, and quite often get d/l's of over 100KB/sec - go to your network connections (control panel), right click on your connection icon, select properties, then advanced tab at the top. Make sure the 'protect my computer and network by limiting access.....' ISN'T ticked.

Also check you're not using a proxy server in IE (tools > internet options > connection > lan settings)

HTH...

If your using a router that will be your internal IP ..it will look like 192.168.123.* no doubt

If you are going out via a router then you may have a firewall without knowing it. Nearly all home broadband routers have something called nat built in (called ipchains/IP Masquerading by Linix peeps :) ) . Without a nat you would only be able to connect one pc.

If you have a router with nat then you need to set up port forwarding or put the machine with BT on a dmz.

HTH

As SOSAGES states - port forwarding is better. Having the computer on a dmz does leave it open to atack. :D

Re: NTL blocking BitTorrent ports? (6881 to 6889)
 
I've managed to work out why I was getting slow speeds with BitTorrent: if the tracker is on port 80, NTL's transparant cache intercepts the HTTP request and connects to the tracker from the NTL proxy server.

When the tracker gets this request, it tries to open port 6881 on the proxy rather than on my PC, thus other BitTorrent users cannot connect back to my machine and I get a slow download.

Has anyone worked out how to get round this? :confused: Apart from using Torrents with trackers on other ports, that is.

Cheers

Sorted it now - SHAD0W'S BT client lets you set your IP address so that the tracker won't use the NTL proxy. Get it from here: http://www.shadow2k.org/downloads.php

Wonder why no-one has posted the answer to this before?? (on this forum or any other). People must have wondered why they weren't getting good speeds on BitTorrent/NTL before. Strange.

I use the Shadow Experimental Client to and usually get about 30-50kbps on a 600k NTL connection.I have opened ports 6881-6889.

Does 30-50kbps sound about right or can this be improved?

The fact you're getting d/ls in the 50K's would make me think there's nothing wrong with your setup - although on 600Kb service, i was getting (only on some things) speeds in the 60's - maybe its just the number of other clients you're connected to, or if its not a popular torrent ?

At a guess I would say that on whatever server you are getting it from they have blocked access to port 6881 on that server.

Re: port 6881 blacklisted
 
I doubt it's a problem with your pc, it's not the sort of message I would expect to see from local firewall software - and without knowing what p2p software you are using I could not tell you if you can change any port settings - but I would doubt it.

Re: port 6881 blacklisted
 
This 'may' be caused by the NTL transparant web proxies? IIRC When you download a torrent then part of the process uses HTTP?

I know I had terrible trouble downloading the latest Mandrake Linux ISO's using BitTorrent as the server/tracker was seeing NTL's proxy IP and not my CM IP. Thankfully in my case Mandrake offer HTTP connectivity on port 8080 as well as 80 so it was possible to bypass NTL's proxy.

Some version's of the Bt Torrent software now use PeerGuardian. Some of NTL's ip range have been banned for some reason by the auther of that software. That might be what you are seeing, If not try changeing to port 6882 in your client if it allows you and it should work. :)

Re: [merged] NTL & BitTorrent (ports 6881 to 6889)
 
I just got this error from Bittorrent on my NTL connection and I've also been getting poor download speeds- despite it being completely fine a few weeks ago.

I'm using the latest Azureus client, with no firewall and no router. I changed the port setting in Azureus and the download worked. Unfortunately, it's also been a bit up and down speed-wise. It started off at my connection's full speed, but keep slowing down to around 4/5kbps and then speeding up again. Right now it has levelled out at about 5kbps, although I'm uploading at a much faster rate- which leads me to believe it's something to do with NTL.

Is there anything else I can do to ensure it'll work better on my connection? What if I were to change my IP address in Azureus- would this make any difference and what should I change it to? What's all this port-forwarding and how would I stop the NTL proxy messing things up? Sorry for being a complete n00b, but if anybody could help I'll be extremely grateful! :)

What speed you on? Does the client show a greenlight or yellow?

Can I remind people that the speed depends how many peers/seeders are in the torrent.

Hi all,

Desperate help needed here :-(

I am with NTL on 1mb, but getting awful download speeds using Shadow Client.

I have configured Norton to allow the ports etc, switched off my xp firewall, but no joy:-(

I read somewhere in the forum that SHAD0W'S BT client lets you set your IP address so that the tracker won't use the NTL proxy.

I'm pretty ignorant at this, and was wondering if someone could take the time out to give me an idiot's guide (no really, I am an idiot) on exactly how to do this :confused:

Can I remind people that the speed depends how many peers/seeders are in the torrent.

Sorry - I am on 1mb speed, I was connecting to 28 others but downloading at 5k

This means your ports are still being blocked by something. Check your firewall again.

Okay - am using Norton Internet Security and this is the steps I took:

1. Went to personal firewall - checked on BT Client.
2. Allowed it to use TCP & UDP Protocols.
3. Allowed it to use ports 6881 to 6889

Still the same results :-(

Do you know how I can configure the shadow client to set lets you set my IP address so that the tracker won't use the NTL proxy ?

Thinking this may be my only hope.

Does it have anything to do with this below ?

Re: [merged] NTL & BitTorrent (ports 6881 to 6889)
 
Although I don't use NTL, I have received the download error message "rejected by tracker - Port 6882 is blacklisted." The site had this help: Why is my port number reported as "---"? (And why should I care?)

The tracker has determined that you are firewalled or NATed and cannot accept incoming connections.

This means that other peers in the swarm will be unable to connect to you, only you to them. Even worse, if two peers are both in this state they will not be able to connect at all. This has obviously a detrimental effect on the overall speed.

The way to solve the problem involves opening the ports used for incoming connections (the same range you defined in your client) on the firewall and/or configuring your NAT server to use a basic form of NAT for that range instead of NAPT (the actual process differs widely between different router models. Check your router documentation and/or support forum. You will also find lots of information on the subject at PortForward http://portforward.com/).

Re: [merged] NTL & BitTorrent (ports 6881 to 6889)
 
OK on my 600k connection thru a router im not downloading anymore than im uploading and my upload is limited to 13kb/s. Im currently connected to 2 seeds and 30 peers. My share rating has been between 0.75 and 2, now its at 1.25.

Router has ports 6881-6999 forwarded
Xp firewall is disabled
No errors in the bt experimental client
Only ie is used now and again for sites
In total there are 34 seeds and 1350 leechers
Read every single faq and guide and problem yet still cannot solve this.

Surely it cant just be that im getting these sh1tty speeds since 8am this morning?

Any ideas?

Thanks

It's probably the problem - if the selfish leechers aren't sharing the speed is so diluted you will only get a small portion. Using the advanced tab can you see how fast the others are downloading?

And heres me at 9kb/s :/

Downquark,

How do you know they are being selfish?

jtwn,

Have you actualy tried throttling the upload bandwidth? Because if that maxes out then it will affect your download speed.

SOSAGES 02-06-2004 08:54

Re: [merged] NTL & BitTorrent (ports 6881 to 6889)
 
put your upload on 5k or so for a while - and its torrent like any bit of software like it u can never expect full download speeds, but u can get lucky.

imback 02-06-2004 08:56

Re: [merged] NTL & BitTorrent (ports 6881 to 6889)
 
BT is full of leachers now, it's gone bad, I can still max out my connection every now and then but it's hit and miss.

My advice, spend a day learning how to use news groups, sign up with a provider and go that way, max speed all the time, it's worth the effort.

Yes but if you set your upload limit to a few bytes below the actual limit you get consistant speeds. I was under the impression that 'leecher' meant they didn't upload at all.

Of course somepeople refuse to do it because bittorrent reminds them of communism :rolleyes:

jtwn 02-06-2004 11:42

Re: [merged] NTL & BitTorrent (ports 6881 to 6889)
 
On all p2p apps i set my upload on netlimiter to 12~13kb.

On Azerus the health is yellow, yet i have done everything to make it not go onto yellow.

In the faq - 'If you only see L connections, chances are you have a Port Forwarding problem'

All my connections are L, yet the ports are forwarded and no firewalls or other stuff is on...i might just take that newsgroup route you mentioned... :/

Anyway i thought your download is proportional to your upload so even if you didnt bother uploading you wouldnt get much of a download either?

That is usually the case, but I think it depends how each client is configured.

Use this port scanner to check the ports you have opened/forwarded.

I did try this before and it did report 6881-99 were open.

Ive tried it again -


----------------------------------------------------------------------

GRC Port Authority Report created on UTC: 2004-06-02 at 13:20:10

Results from scan of ports: 6881-6900

0 Ports Open
20 Ports Closed
0 Ports Stealth
---------------------
20 Ports Tested

ALL PORTS tested were found to be: CLOSED.

TruStealth: FAILED - NOT all tested ports were STEALTH,
- NO unsolicited packets were received,
- NO Ping reply (ICMP Echo) was received.

----------------------------------------------------------------------

All ports closed? Is that normal? Those ports are forwarded and werent in use when I did the test...

Thanks

Repeat the test while the torrent is running, you should get some of them 'open'

jtwn 02-06-2004 15:30

Re: [merged] NTL & BitTorrent (ports 6881 to 6889)
 
Oh yeah, im using a different port in Azureus - 50160, i ran the test then and it said its open.

Ive also tried this but get 'Attempting connect to: 62.254.0.36 (cache8-nott.server.ntli.net) port 50160
Fail!
Unable to connect. This likely means you need to adjust your port forwarding configuration, or there is no client running on that port. '

Dodgy ntl cache maybe? Just a non-technical guess :) I have tried putting a proxy in Azerus but i dont remember a difference.

Health is still yellow on the torrent...i just cant get my head around this :(.

Ive had a look at the logs..alot of requests, some are eventually cancelled, nothing to myself looks too bad but then again...to me. I might try ABC as a few people on a long bt thread on port forwarding problems said it worked for them.

by the looks of this I am coming into this thread quite late and I dont have time to go over the last few pages as I am leaving for work in a minute.
By the looks of it you are trying to get your connection working in active mode rather than passive mode, correct??
I will tell you what got my connection working green in Shadows experimental with Zone Alarm Pro.

opened ports 80, 6000-6999 for both incoming and outgoing TCP/IP on the trusted and Internet Zones.
Manually specified BitTorrent to use ports 6000+
Specified my IP as bittorrent was detecting my proxy as my IP address and it was causing me to act as passive (yellow) rather than active (Green). When I did this BitTorrent said I would have to restart my client for the changes to take affect, this didnt work, it wasnt until I rebooted my computer that the changes took effect.

Now I download at some mighty fast speeds and my upload works properly at last :D

Re: [merged] NTL & BitTorrent (ports 6881 to 6889)
 
Ok i entered my ip in azurereus and now im in the green and receiving remote connections :)

but...now i am only uploading at half what i would without the ip (6-7kB/s) and my dl is, tbh, worse :(

Help!

It could just be the particular torrent you are on, have you tried it on any different torrents? (dont forget your speed can be affected by the speed and quality of the connection that other peers are on)

Re: [merged] NTL & BitTorrent (ports 6881 to 6889)
 
I guess, but i wouldnt of thought that many people on poor connections would be downloading a 4.5gb file..im just going to try another torrent now.

Hi

I am on NTL 1 MEG Cable Modem using azureus.

How do i open ports?

I only have 6881 and 6882 open according to the check above. I have no firewall and no router.

Also where do i enter my IP IN Azureus?

What are the ideal settings i should enter into Azureus - i average 60 download but i should be getting nearer or over 100 on a well seede torrent.

Thanks

Dave

I recommend you do use some kind of firewall or router for protection. But since you don't have one, then you don't need to worry about opening ports.

As for making it faster try limiting you upload to something like 23. Nothing else can be done, bittorrent isn't the most predictable of protocols.

You shouldn't enter your ip unless you have problems but it's in config under force ip address on tracker or something.

any probs in the belfast area with torrent files. i have gone from a solid 125k a second to less than 10k a second. web browsing is unaffected and microshaft update come down at a good rate of knots.

Then I'd guess the uploader (s) arent uploading at the same rate.
If browinf etc is fine, the only place the problem can be is the person (s) sending you the file. Check the amount of sources, look at them in detail and see how many of the sources have ALL the file.

I dont use torrents now purely because I could get stuff faster on 9.2k dialup!!

is this not an apple mac client? i am using the latest shadow client here btw. oh look on the bright side my download has gone up from 10k/sec to 25k/sec, with little bursts of 125k/sec. so no worries NTL must be ballixing about again. thanks for the replies guys.

just download and installed azureus. pretty slick :). does it resume BT downloads auto matically if your router/pc/modem goes down.
