notroll.in : heavy ddos, page down, stratum massive rejects and long stops
coinotron : heavy ddos, page down,  long stops , ddos protection failed
litecoinpool : pool down , page up.
newozcoin : under attack, slow like snail massive rejects but some kind of working
ltcmine.ru :  down.  update : look's ok!


WTF!!!


edit:

look's like attack is over. for now.

Indeed.  Can confirm notroll.in and coinotron.  Sad.  Watch the notroll.in pool thread in this subforum for updates.

ltc.kattare.com seems ok

kattare had 25% stales before attack so no need to attack there. of course correct me if those problems where corrected so i can jump to kattare[burnside's].

so what does it mean? no LTC mining, no inflation, price goes up... :)

doesnt seem to be effecting the price much.

no it means someone can pump and dump  or double spend.

no.  pools being ddosed !=51% attack being successfully pulled off. pools have been ddosed before, this is not the first and will not be the last pools are ddosed. people should always setup automatic failover (even to solo mining). the network hash rate does not seem to have been affected, as far as i can tell

I have a failover and its not working now, also I just finished pool testing so i have 20 configuration files for many combination of pools and... cant find working one.

I'm on ozcoin now, which is under attack for a long time now, and getting 7% rejects + 4% fee its a drastic 89% efficiency.

coinotron does appear to be processing shares now, but the website is up and down.

This looks like a major coordinated attack. But even if we all have to solomine until eternity, they cant stop the Litecoins from flowing...

ltcmine.ru is up, been accepting shares throughout the attack too

Someone's trying to game the difficulty, looks like it's not working all that well as many pools are surviving, coinotron and notroll are all still accepting shares, all the other pools are still giving/accepting work

Lame 51% attempt is lame

yes, read the OP. they are accepting some but have a lot of long pauses , up to few minutes.   and even when accepting the rejects rate is really bad.

Can such a thing happen to btc? Why (not)?

ltcmine.ru seems fine, switching

yes. bitcoin is atleast theoretically even more vulnerable to this due to all the centralization and fewer and fewer pools and people having bigger and bigger share of the total network hash rate. all it would take is a few pool operators colluding (or even a few pools having their systems compromised/taken over) to potentially 51% the bitcoin network.

Just solo mine, no ddos worries then.

litecoinpool hashrate is up, coinotron page is up.   looks like its over. massive but short.

notroll still accept share =)) if some one plan to ddos all pool and think they have a change to 51% attack, think about it=))

True.

I think that it was just a free DDoSer services test. They will back soon, when attackers will be paid for the real attack. So, switching to solo or p2pool is recommended as soon as possible, for the next few days.

Notroll is accepting shares, but website is still down.
Wonder what will this do to the price.

Price looks healthy, I think this all was just a blip in the litecoin rocketship exiting the atmosphere

Tenner says Knowledgeable got pissed off when we slagged him for his 51% thread and thus DDOS'd everything. 

If only you knew  ::)

I also had the same thought. There seems to be a loit of animosity to litecoin, which has just made me even more interested in litecoin now.

Typo there..

I mean If only you knew...

As in I know who DDoSed the pools...

anyways...  ::)

Do tell, is it our bible bashing friend Luke?

Nope and I'm not gonna tell you who it is  ;D

So this is the fresh team for DDoS?

At the risk of stating the obvious peer2peer is inherently DDOS resistant. The problem is mining pools.

Solo mine or use p2pool and you don't have to spend a second worrying about DDOS attacks. Or configure a failover to p2pool or solo mining if you must use a mining pool.

Right, p2pool is one choice.

Replying with p2pool website as a note to self for when I get home:  http://www.p2pool.org/static/

Notroll is very slow for me today and having slow submits from my miners....another attack?

Sorry, I don't follow the alt currencies sub forum too much, did you call my name? What's up?

Yep.   :-[

I have a feeling it is someone with a pool attacking these larger pools to get more for themselves.  Just a guess...

Motherfucker.  Now all my pools, including fail overs are down.  When are the big operators going to get some decent DDOS protection? 

DDOS protection costs a lot. Only biggest BTC pools can afford it.

Exactly, and even then, even btcguild has no *paid* ddos protection.

Well, that would explain why my connection conked out last night while I was at work, and I guess why my results have been pitiful so far (just started mining a couple days ago). What a time to start, huh? Here I was thinking I must have had my settings all screwed up or something.... though, I probably still don't have them set right. :-/

P2Pool FTW  ;D

Read the plans better, the free plan has no DDoS mitigation.
