links?

proof?

Hmmm all my apps work fine here, no problems at all. It could be the application you are using, or possibly your router. I recently experienced my router(Linksys) locking while running utorrent, and it was the firmware. You might be able to find some help here »Filesharing Software

Adelphia seems to be blocking bittorrent seeding. Regular bittorrent is fine, but when you complete/switch to seeding, the new incoming connections are forced close. Guess they\'re sniffing packets and seeing the file is completed header and then dropping.

The symptoms are like the ones described in the RCN, OOL, Cox, Shaw, Rogers, etc... forums. If you tried to seed from a cold start, you\'ll see peers try to connect for like half a second, and then get dropped.

Maybe it\'s just a regional thing. I\'m in SoCal, like the original poster. This started about a couple of days ago. Go read the RCN thread on BT throttling.

They were denying it all along until that one exec finally admitted it. I remember it was on the front page news.

»RCN Exec Speaks on Traffic Shaping

I've never had any problems with bit torrent and seeding the files. I just use bit torrent for downloading live music, so maybe it sniffs illegal files too...:)

I guess adelphia could be denying it...but I would expect everyone would have the same symptoms...not just a few. Oh well, go figure.

"Go read the RCN thread on BT throttling."

No, because that is not relevant. I want to see these links that show that Adelphia customers have these issues.

Thank You

i might also be experiencing this issue. still trying to track it down...

one other explanation is that a large percentage of the rest of the clients have been updated to the versions that include encryption... and at least some people are suggesting that one should ONLY connect to clients that have that option. little groups of clients that do that can drastically change the behavior of a swarm.

it's all happened at about the same time, hard to point the finger with conviction.

i'm starting to lean towards the client issue.

My Limewire Pro works without a hitch, my BT Client works with no problem. Me thinks someone cannot get his programs configured correctly and wants to point his finger at someone else.

I might suggest going back to Earthlink.:)

No animals were harmed in the transmission of this post, but the pitbull living next door is living on borrowed time i tell you!

do you seed heavily with your bt client?

reply to jeffy82
Found this via a Google search after I noticed my Limewire uploads have dwindled to virtually nothing for no obvious reason.

With others having similar problems at exactly the same time, methinks the problem is Adelphia.

Does anyone have a workaround?

I had to quote myself on this one. Read my post again. Limewire works fine, and BT works fine on Adelphia's network.

I get 750kbps or more a minute with uTorrent with Adelphia with or without any encyption .I have UTorrent configured with 40 connections open .

With Peer Impact a commercial entertainment industry approved p2p network . Ive been able to get speeds of 800kbps or higher but thier seed servers are based in Albany New York and thier offices are in Saratoga Springs so they are not to far from me in Southern Vermont .
I seed all day long with Peer Impact flooding my upstream most of the time .

Peer Impact is a network aware p2p network that gives you system credit for uploading paid for content.

»www.peerimpact.com

I dont see Adelphia packet shaping p2p at all when running tests with ethereal for Peer Impact and the Peer Impact developers who I chat with daily would tell me if my connection was losing packets .

I have had some speeds issues in the past with Adelphia but they fixed those after a few months of me protesting .

Of Course Im not in Soutern Cali, so It may be a regional problem as some have indicated in this thread .

Could this be your Problem With Bittorrent


Modems/routers that are known to have problems with P2P apps (from Azureus, but applies to µTorrent too),
List of routers that have problems with Azureus (and µTorrent), if you have one of those... either try the solution specified with it (if there is any), update the firmware or get a new one. If your router or modem freezes/reboots, you should turn off IP resolving, DHT, and/or reduce the number of connections to try to remedy the problem, even if it's not on this list.

Reason not yet verified
Apple airport extreme (802.11g wireless with wep 128bit)
Due to too many connections
SpeedStream 5660 in Router/NAPT configuration. There is no firmware newer than 2.(3).7. Switch to bridged mode and firewall your network to fix it. Otherwise, when it dies just power-cycle the router and continue on.
The following modems/routers have known problems with too many global connections, limiting them to 200 or less should fix the problems:

Netgear WGT524
D-Link DSL-G664T
Linksys BEFSR41V4
W-Linx MB401-S (and SMC Barricade 7004 BR, which is identical in construction)
Netgear DG834G
Westell 6100
Due to UPnP
Most D-Link 5xx and 6xx (can also be caused by too many connections)
Zyxel Prestige 660hw
Some SpeedStreams
Common fixes for routers/modems freezing/crashing/etc
Updating the router firmware
Turning off the UPnP (in the client and in the router) and doing manual port forwarding
Restricting the number of global connections to 200 or less (may need to go below 100, depending on the router)
Turning off DHT
Lowering net.max_halfopen and bt.connect_speed
Putting the modem/router into bridge or gateway mode (doesn't apply to modems that aren't routers)
Getting a new router/modem
Sourced from (with some modifications): Bad routers - AzureusWiki

Special note for users with Linksys WRT54G/GL/GS routers, there are severe problems with them when running any P2P app (read for fix)
The default firmware for Linksys (and all replacement firmwares except for one) have a severe problem where they track old connections for FIVE days, which causes the router to hang when using P2P apps, or any software that generates a lot of connections. DHT only aggravates the situation because of the number of connections it generates.

Linksys has yet to address this issue, but there is a fix. If you use alternative firmware, you can put in a start-up script to fix this problem. DD-WRT and HyperWRT support custom start-up scripts. I am not responsible if you screw up your router, so you do this at your own risk. This page has instructions on recovering a bricked router. For those using HyperWRT or willing to switch to it:

HyperWRT2.1b1 tofu12 (54G/GL only, excluding hardware revision V5 of 54G) (does not require the following steps, but it can still improve performance over the firmware's defaults)
DD-WRT v23 beta 2 (54G/GL/GS excluding hardware revision V5 of 54G) (requires the following steps)
HyperWRT2.1b1 Thibor (54GS only) (requires the following steps)
You should avoid upgrading over a wireless connection, since the connection may drop out.

To upgrade the firmware, HyperWRT2.1b1 tofu12 or Thibor ONLY, follow the instructions on HyperWRT Manual - Installation
Note that tofu12 names the .bin file as code.bin, not hyperwrt*.bin

Go to the web interface (default password is admin) by typing »192.168.1.1 into your browser.
Click Administration, then Edit Startup. Put the following commands in the box:

echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts
echo 1 > /proc/sys/net/ipv4/icmp_ignore_bogus_error_responses
echo "600 1800 120 60 120 120 10 60 30 120" > /proc/sys/net/ipv4/ip_conntrack_tcp_timeouts
Click Save, close the window, then click Save settings.
Reboot the router (the Administration page has a Reboot button) and you'll be done.
To upgrade to DD-WRT, follow the instructions on this page. The Right Way to Flash Your WRT54G/GL/GS. The following instructions are for DD-WRT only

Do not use the web interface method as it cuts off part of the commands.
Enable SSH (Admin, Services) as we are going to use the NVRAM method @ »wrt-wiki.bsr-clan.de/index.php?t···M_Method
Login to the router with an SSH client (root/your password).
Put the following commands into the SSH client.
~ # nvram set rc_startup="
> echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts
> echo 1 > /proc/sys/net/ipv4/icmp_ignore_bogus_error_responses
> echo '600 1800 120 60 120 120 10 60 30 120' > /proc/sys/net/ipv4/ip_conntrack_tcp_timeouts
> "
~ # nvram commit
~ # reboot
The system is going down NOW !!
Sending SIGTERM to all processes.
Note the ' instead of " on the third command line. Using " on the third command line closes the set command (as on last line), meaning that the last command will get cut off prematurely.
Make sure your "Maximum Ports" is set to 4096 on the Management page.
You can check the settings worked by loggin in via SSH and viewing the contents of each fileas below or using the "nvram get rc_startup" command.
~ # more /proc/sys/net/ipv4/icmp_ignore_bogus_error_responses
1
Enjoy instant µTorrent speed increase from pretty much zero on each torrent to full speed!
Thanks frankw for the instructions for DD-WRT

Remember, I am not responsible if you screw up your router, so it's your problem if something goes wrong. However, if something does go wrong, this page has instructions on recovering a bricked ("dead") router.

If you require further assistance with either firmware, please visit HyperWRT.org (the main site does not have the latest builds however), HyperWRT Forum's Advanced Help Section, DD-WRT.org, and DD-WRT's Wiki.

My personal SPECULATION and OPINION.

said by CED magazine article :

Fawaz said the capital cost of doubling bandwidth (on just one 6 MHz channel) runs between $4 to $5 per home serviced.

Re: [Connectivity] Adelphia Blocking P2P Packets

I think this site is tesament to the fact that no one is interested in P2P unlesds everything is free.

For this article to suggest that cable companies need IPTV to provide "free" TV to a computer is very naive. this site proves that people are not interested in paying for anything, they want it all for nothing...whether its content or a connection.

Currently P2P impacts everything that the majority are trying to do online.

Like Macleech I am speculating, but if my neighbour is impacting my enjoyment......
