Bitcoin Forum

Seems that the ISP's are now messing with the p2p network to the point that bitcoind is not syncing, or will take forever to do so. Torrents are no longer working, if they do, it's not worth it.. I believe they are slowing p2p down to the point that this WILL affect bitcoin users worldwide sooner than you think.. This is the lowest price I have seen bitcoin in a long time, and I believe it's due to this ISP messin with the speed at which you can download the blockchain..

Assetion Failed!

Maybe I'm wrong, but I dont think so.. :(

This error is happening every half hour or so..

bam?

ISP's messing with Bitcoin?

I know certain ISP's have throttled the speed of torrents and gnutella in the past due to the high amount of upload traffic from them, but I don't think any ISP has throttled Bitcoin traffic yet.

Currently a full node only needs to download a maximum of 144MB per day, thats not a lot and shouldn't concern ISP's.

That error you are getting doesn't indicate that your connection is being throttled. What version are you running?

The last three versions all come up with the same error, only with a different number.. And whilst I also think that yeah, x amount or so of blockchain should'nt bother the isp's, they are defo blocking p2p here where I live, as in a test, I started a new release torrent and watched it plummet to 0 kbps within less than a minute. Ok, so tried again.. and again.. stopped the torrents now, since it's pointless here, it's got that bad.. and p2p traffic is p2p traffic. I dont think Isp's can differentiate between packets of torrents or blockchain?

Just after crimbo people will realise what I kinda been saying for a while.. all the Isp's need do is block p2p, period. Dont think they wont, assume they will.

Shoulda kept the kill bitcoin thread opened..

Isp's are like google..

And in my opinion, filtering the net is'nt killing it.. it's already dead.

Which ISP are you using?

Lol, this is why I think it will become a major concern to bitcoin users.. Virgin Media..

Just did reformat over weekend, re-installed bitcoin, starts, then closes, firewall shows it starting, but dies, all within less than 10 seconds every time. I am at the point of just giving up, cause even slowing down p2p, will drastically affect download of the blockchain. Quite simply, unless the bitcoin devs are introducing the end of xp support (they should'nt, as the uk gov still pays ms for updates..) slowly, then the only explanation is that virgin branson..

I've heard from friends that have Virgin Media that they are a nightmare, they're blocking torrent & streaming movie & live football sites etc. Nothing would surprise me with them.

It might be just your computer, or perhaps they are really fucking you over. In any case. Get yourself a VPN or/and start using TOR.

I'd say I have a reasonably stable system, considering what I've added to the mobo, it's all running fine, it's just strange that since 0.9.1, I have never had a stable bitcoin app, that actually stayed 'running' like older versions did, kinda like start and forget, I was mining for 6 years constant up until 0.9.1, and since then, the problems are increasing, and the only time I've formatted in last 6 years was at the weekend, which I only did to start afresh, in order to check if my hard-disks were ok, they pass..

As for moving to a new OS, nah, I stopped upgrading when the icloud came along saving my work on others pc's, I thought, how will this affect my copywrite to my own work, if it's saved first on someone else's comp, as this means they own the intellectual right's due to them having the origional! So no more upgrading for me, I got 6tb of audio running fine on ye auld sp3, (shame about only being 3.odd gigs mem). Tbh, I found windows seven prevented the majority of audio apps I have from working in one way or another..

3rd attempt at starting, seems stable for now, but will it be running in the morning.. hmm..

If its starting then its not an ISP problem, if it was blocked it wouldn't start.

Um, slow down ;) It took 4 starts in order to actually start, and it died everytime it connected to the net, not that I think it's being disconnected, or blocked, but what if the p2p protocol was restricted (using data caps? - I dont have data caps, but the method would work) to the point that the app could not download the blockchain, even though it could 'see' it? it's like, downloading a movie at 0.01bytes a second, would this not time out the app?

I'm sorry buddy I don't know. Virgin Media can see the file size and possibly block or restrict transfer of that file.

i dont think That ISP's would do that. If you are mining maybe there are some errors but i guess it would be fixed in some time. Regarding the value of bitcoin , the world is currently upgrading to IPV6 connection and it can be the possible reason why your btc dont sync. By the way, the value of BTC is starting to reach at its peek again. :)

Hmm.. I aint been mining now for three months since my sync prob's began, I still think that Isp's can not only slow down p2p, they could charge for it...?

As for btc climbing, I've noticed when gold goes up in value, btc drops and vice versa..

Unless you've got serious hashpower its a complete waste of time solo mining anyway. You'd be better joining a pool for regular smaller payments, plus you wouldn't have this problem ;)

I prefer solo mining, cause ya get 50 btc with every score ;)

Block reward is 25 at the moment and has been for a while, you could always try bitsolo.net (http://bitsolo.net) or solopool.net (http://solopool.net). That way you haven't got the hastle of trying to keep the wallet in sync plus you get a nice payout if you find a block ;)

Shows how long it's been since my last score lol..

Lol. Difficulty has gone through the roof since as well that's why solo mining is hugely unsuccessful unless you have serious hashing power. Some people still solo mine on a smaller scale for fun but the chances of hitting a block are very slim.

As I see it, I leave my pc running 24/7, and it may as well be doing more than one thing when I go to sleep..

Yeah why not don't blame you :)

As I said, it just wont sync.. comes back from lunch, bitcoinapp not running when it should be.

2014-10-15 12:00:38 ProcessBlock: ACCEPTED
2014-10-15 12:00:38 socket recv error An existing connection was forcibly closed by the remote host.  (10054)

This is preventing me syncing, but what I cant understand, is what or why the app is terminated, I'd love to know why it terminates.. even if its toiling to sync, it should remain active no?

Edit: Would'nt the remote host be virgin?

This is not an error due to ISP interference, it could be any system error. 

1. Virgin Media are by far THE worst ISP you can be with. the way there lines work you loose most of your speed during the day due to a very very over sold network.
2. Bitcoin should remain active even if theres no connection at all so theres a problem on your side if its terminating
3. most ISP's now throttle P2P connections and there software does not reconise the diffrence between Torrents or Bitcoin as they both use the same protocol
4. to bypass ISP throttle there are a few solutions
    4.1 invest a small amount in a VPN service such as PIA (private internet access) this encrypts traffic so ISP's dont know what it is being sent or received meaning
         your connection should be unthrottled
    4.2 let Bitcoin sync at night alot of ISP's use traffic management to keep the network fair for all during peak times so off peak normally considered 9pm to 6am is
         a better time to download
    4.3 find a free wifi zone to use. these usually are business grade connections and bypass alot of censorship and restrictions including P2P


normally an app terminates because its run into Ram or CPU issues over a period of time, the O.S will the force the program or app to close to save itself from more issues arising the is very clear on most O.s's    

Dunno likes, I mean, I'm not the remote host, so the next suspect would be virgin followed by the blockchain.

Please stop telling me that it's a systems error, my pc is old but fine, and with a fresh format and nowt installed, (for testing purpose's) and I never had problems previous to the last 3 versions of bitcoin

So it's either Bitcoin app, virgin, or blockchain, take your pick, I'm claiming virgin, in that they are blocking p2p traffic, nothing else.

no the host is not virgin it is normally a program on the PC thats not the same program ordering the program to close

e.g windows forcing bitcoin to close classes as a remote host closing bitcoin

I've kinda already stated most of what you said, but the app crashes as soon as the socket received error kicks in, which is from a remote host, not this end. I agree the app should not terminate, especially with a fresh system, so it occured to me that they may not just be throttling p2p, but sending some sig kill/terminate to the 'offending' app that wont show, since it would be sent via snmp.

its not virgin. its unlikely to be the blockchain as you cant sync so its either a bad install of bitcoin which would easily be solved with a fresh reinstall of bitcoin simply back up you wallet go to C:\Program Files\Bitcoin delete all the contents and reinstall this will the be a fresh install

if this dosnt work then somethings wrong with either the windows O.S or your network.

At last your getting the hint: Network.

not virgins network YOUR Network

my only other suggestion is to try this
go to
C:\Users\Windows 7\AppData\Roaming\Bitcoin
and replace Peer.dat wih this one
http://bloginhell.me/wp-content/uploads/2014/08/New-WinRAR-ZIP-archive.zip
take the peer.dat file out of the zip and place it where the old one was
theres a small chance this will help but its all i can recommend right now

Virgins network mate, I know docsis for sure, and see sig_kill in modem ;)
