They have real USD prices now, they don't seem to be conversion from RMD they have posted

E9+: $2480
E9++: $3880
E10: $5230

Yeah a bit steep. Mabey if BTC was $20k like it was a few days ago.  Grin Roll Eyes Cry

before the bitcoin was hit >15k USD ATH . changelly transaction were doing fine it is until recently when the bitcoin transaction was overload, the changelly tx/rx transaction affected, so the main problem is in the bitcoin network not on changelly exchange service.

I respectfully disagree. The BTC network is a bit slow but that is a known factor and NOT the cause here.

THe cause here is the changelly system is issuing coins, THEY DON"T (yet) HAVE. They should be waiting for any incoming BTC to be confirmed before spending it, period.
Mine was literally 16 transaction deep before I found confirmed coins, all those had to be confirmed before it got to mine. In the mean time, double-spends are of course possible so it's just a bad method to use when you chain up 16 deep pending transactions, no wallet software will let you do that, most won't even let you do it 1 level deep until there's at least 1 confirmation on the incoming coins your trying to spend. That is FAULTY SOFTWARE.
Perhaps it worked great when there was far less transaction in the bTC network, but, come on, scale your crap so it functions, and by all means, don't give people the false impression they'll have their BTC "in 30m" as their estimator said when I initiated the transaction, and STILL says it now, when they are running 1-2-3 I've even hear of 5 days behind. If they had any reputible practice happening, they'd have stopped taking any new BTC (at least outgoing) transction until they clear they're backlog. RIght now they are in a tizzy, many of their real transaction are falling off the back waiting 5 days, miners won't pick those, they have to wait till nodes stop relaying them and re-issue them, a complete mess. I'd surmise changelly is responsible for a good percentage of the perpetual 200k mempool transactions.

After a day and a half finally my transaction was picked up and has a confirmation. Their support is hilarious, "we're overloaded so we can't respond to you" and they proceed to listed reasons like recent weeks explosion in btc activity etc etc etc..no, the reason is, you were not prepared and are too greedy to stop taking peoples new fees/coins and not issuing out the ones your supposed to.
Well, then you should stop taking new transactions for BTC then if your system can't handle it! And certainly don't tell people it's gonna be 30m when the initiate a new transaction.

Now the website lists them all for $0.00 and delivery Feb. Free!! I'll take them all please! I'll even pay for shipping!

Gotta love this develop the website on the production instance for all to witness.

Can anyone actually get a purchase to go through on this new page? Sorry for cross posting, but I keep getting my orders mysteriously disappearing...
I also can't get my ship to info in there very properly - Had to jam in my Canadian address in the "other details" or whatever that field is. I see people had some luck with Lynn direct via skype?
I ordered direct from Lynn via skype back in Nov when then had them then. She made invoice, via skype, I wired money, 2 day later she confirmed, via skype (after I aksed), 2 days later she send tracking (after I asked) via skype.

This new website just came online a few hours ago and looks to be a work in progress, I'm not sure they even have machines, E9 or 10. I wouldn't order anything from the new website yet.
46  Bitcoin / Hardware / Re: Ebit e9 miner with 6.8Th/s from Ebang company a new rival for existing producers on: December 19, 2017, 09:17:13 PM
Ebang has a new website, which is great, because they actually now have a proper web shop system.  Smiley

Ebang official website: http://miner.ebang.com.cn/

But they do have a pricing mistake at their website.

You can compare the Chinese and the English website,
and see that they have forgot to convert the RMB price to a USD price.

So, for example 6840 RMB price is actually about 1035 USD, not 6840 USD.

You can register, but none of the drop downs in the important areas like shipping address and cash register and shopping cart, seem to function. I think they are developing the website still, live, online.

BTG node seems like a joke .I can't even get it to sync despite trying several different ways.
  • I've tried copying my BTC  full nodes block/rev files from the blocks dir to the oct24 or whatever date to the btg node block/rev files  (same as I did with BCH) , the  BTG node won't even start then, segfault/coredump. Real nice.
  • I've tried to let it sync form scratch with and without bootstrap option
  • i've tried bootstap with force connect option to my full btc node, that half works, gets to about may 12 2012 before it hangs and stops.
  • I've tried opeing the upload ports for BTG so other nodes can see I'm willing to relay and not just a drain on other nodes. I see the peers come and go in the debug window and like they dn't like me for some reason and after downloading a few blocks I end up with no outbound peers connected over time.

I've plenty of upload and download bandwidth and have several other crypto nodes running and never really  had any issues.

What's it take to get your btg node going? Is this just junk software? Last I check there was only 24 nodes running for BTG.
 I'm start to get the distinct feeling BTG doesn't want the avg. joe to be running a full node.
48  Bitcoin / Bitcoin Discussion / changelly problems and practices when dealing with BTC on: December 19, 2017, 06:58:32 PM
I've used changelly before and didn't have an issue, I used it last night to transfer from BCH to BTC and it took my BCH, gave me a txid for the BTC but that tx is unconfirmed over 12hrs later. It's not low fee either, it's got .002btc/kb fee.  Looking at it, the single input to the sending address is also unconfirmed and many of the 300 inputs to that address are unconfirmed, basically the sending address doesn't have confirmed btc to send you.
So they are sending you BTC THEY DON"T HAVE!

Is anyone else having issues with changelly, and I wrong to be shocked about seeing that they are sending me coins from unconfirmed balance places?!?!?!?
49  Bitcoin / Hardware / Re: Ebit e9 miner with 6.8Th/s from Ebang company a new rival for existing producers on: December 19, 2017, 05:14:20 PM
Their website is completely changed now. It shows e9+ for sale but prices seem way out of wack, $650 for a PSU?? $6300 for e9+?  haha.
I think they brought a template in and will change the product and prices later. Rather disconcerting they do stuff like that, edit their website on the production instance.
We'll see if they actually announce anything!
BTW, "firmware" 6.0.20.48 firmware is in their support link now, if anyone cares. Not sure what it really does. It comes down in some messed up format and mislabled 6.2.20.48 but when you untar it it's 6.0.20.48.
50  Bitcoin / Hardware / Re: Ebit e9 miner with 6.8Th/s from Ebang company a new rival for existing producers on: December 18, 2017, 07:36:54 PM
Hey guys. I just got an E9. I am trying to get the Ip address out that thing. Have no success yet. Any help are greatly appreciated.

thanks,

Your going to need a laptop.

Download wireshark to your laptop, take a network cable and connect it directly to the miner and startup wireshark, the arp messages will tell you the ip it's using.
Set your laptop network to another IP on the same subnet, then you'll be able to log to the miner and change the IP via the webui. You'll lose connection at that point, but you can then connect the miner to your regular network and connect it from your new ip and off you go
51  Bitcoin / Hardware / Re: Ebit e9 miner with 6.8Th/s from Ebang company a new rival for existing producers on: December 18, 2017, 04:24:17 AM
This may be a dumb / noob question. Being that btc uses SHA256 algorithm, is it possible to mine peercoin with this miner as well?
Yes. point to a peercoin node or mining pool and your good to go.
52  Bitcoin / Hardware / Re: Ebit e9 miner with 6.8Th/s from Ebang company a new rival for existing producers on: December 13, 2017, 03:37:41 PM
I'm a "real" user.
These are good miners. not quite as efficient as an S9, they work. Some reports of occasional issues like a hash board going out but that happens with any manufactuer. YOur not gonna get any support from ebang, but that seems par for the course with most of the asic makers.
All in all, they were a great deal direct from ebang@1250 or whatever and are proving to be nice machines. I wouldn't give mine up.
53  Bitcoin / Hardware / Re: Ebit e9 miner with 6.8Th/s from Ebang company a new rival for existing producers on: December 08, 2017, 06:45:07 PM
I am going to explain this one last time. This is third and last time I will explain it. Its going to be long winded and complex.

Lets say burn out a miner remotely. Better burn your house down in honor of the
Talking Heads "Burning Down the House"
This Miner will self destuct in 10 seconds


A. You connect to your miner Smiley

B. Appweb sends back the esp file with a little surprise before you Finnish clicking the submit button on login.

C. Its not the miners that are connecting out, Its the machine your using a browser with.

Lets look a little closer.

Before the browser can render a page, it has to build the DOM tree by parsing the HTML markup. Whenever the parser encounters a script it has to stop and execute it before it can continue parsing the HTML. If the script dynamically injects another script, the parser is forced to wait even longer for the resource to download, which can incur one or more network roundtrips and delay the time to first render of the page. Now If you connect to the miner and are retrieving a javascript file from them is it run on the miner noooooo.
It is run on the client. Or the big box that has monitor you connect to miner with.

So thank your Mr Security engineer. A fucking firewall in front of every miner will not catch it because.

A. Its ssl encrypted because its sent from your client.
B. uses you pc that you like to whatever on to get the code.
C. Since it uses javascript you can get/alter/inject or turn off your fans and start your house on fire. Smiley

Lets Create a little sample exploit to Hmm ahh Change your mining pool remotely. Then Hmm set your asics on fire.
First lets disable the submit button

// Disable submit_callback submit buttons redirect to the ajax code to rewrite the variables and submit to the appweb controller after login in
$form['submit'] = array(
);

We have not logged in yet Smiley

Now as you click any code It can basically take any variable and change it like this.
Lets start with the meltdown

         Turn off all those pesky safety features, Like turn your fans on low and disable the auto shutdown
        
         $.post("/alarm/SetAlarmthreshold"

                        setValue("cgminertasknoanswer",data.feedback["cgminertasknoanswer"]);
                        setValue("tempalarmvalue",data.feedback["tempalarmvalue"]);
                        setValue("deviceclosetempvalue",data.feedback["deviceclosetempvalue"]);
                        setValue("devicesllowalarm",data.feedback["devicesllowalarm"]);

         Disable your fan,              
                        setValue("devicefan",data.feedback["devicefan"]);  //设备风扇
                        setValue("devicefan2",data.feedback["devicefan2"]);  

         Set you PLL to the MAX:
                       setValue("pllconfig",data.feedback["pllconfig"]);  

Now That your temp is disabled but it shows its normal, your fan is set to low your asics are set to high.
Remember this is a simple example you can do alot more.          
Because of this is on every page and

<script type="text/javascript">
var _bdhmProtocol = (("https:" == document.locatio[Suspicious link removed]otocol) ? " https://" : " http://");
document.write(unescape("%3Cscript src='" + _bdhmProtocol + "hm.baidu.com/h.js%3F938ac8f30a6ec8c517f65bcdae695111' type='text/javascript'%3E%3C/script%3E"));

Now as you connect to the web interface and it pulls there javascript.  Your miner has been turned into giant bic lighter.

Black hole the address. This is like one of the more simple back doors.

You disabled/killoff  your appweb, I thought. I still use the appweb, but I got rid of all this crap from the esp files in my "firmware". the miners are still trying to talk to at least two entities in china when dwang starts up, it's still a good idea to box your miners in by firewall, IMHO. tekcomm is right though, those esp files are also loaded with phone home crap that is execute on the browser/machine your using to connect to your miner. (if you havn't cracked your miner, al lyou have to do is view source on the frame in the web pages and you can see the stmts that are making your client machine connect to outside sources).

I thought about ditching the resolv.conf too, but that seems rather brute-force-ish. The rule on the firewall works great, allow out to your pools via FQDN so you don't need manage the round-robin ip's the pools use, then deny all  outbound from your miner group addys.
#      From   To   Priority   Source         Destination   Service   Action   Users

37      LAN      WAN   9   EbitMiner40-50           Any            Any      Deny            All   
I have defined on my firewall/router EbitMiner40-50 address object  as a range of addresses that only the miners fall in and MinerPools address object  as my pools by name, the router will keep track of the various ip's associated with those names
I've had a running trace on 37 to show me exactly what's being blocked..
After dwang is going, nothing, but during dwang startup..watch out, it wants to connect to all kinds of internet ip's, as well as many 192.168 internal ips they must being using in their development office.

I would HIGHLY recommend anyone with a ebang miner to create that rule-set on their firewall. It won't affect it's operation, there's no hack or code required and you don't need to touch your miners or break into them, just some rules to box in your miners so they can only talk to your pools,  and keeps your miner from reporting all kinds of stuff to various entities in china.

Has anyone tried to just compile cgminer for arm and see if it picks up the asics on that thing? Never looked into how the mining software actually works, not sure how they talk to the asics.
the dwang crap really needs to go, dirty dirty stuff.
56  Bitcoin / Hardware / Re: Ebit e9 miner with 6.8Th/s from Ebang company a new rival for existing producers on: December 07, 2017, 10:18:01 PM
Actually I just added a rule to allow to my pools and deny everything else.
The deny everything else has produced about 8 denials/hr/miner to various places, most of which you can ssh to and get a prompt. WTF ebang!?!?!?!?

127.0.0.1 it.



I made a rule on my firewall to deny packets from my miner group addresses out to any of these hardcoded BS sites. THe nice thing about that is the firewall keeps track of how many times it was denied and you can see those stats.
So far, hm.baidu.com was only once, it doesn't seem to get called on every page load. The e.g703.cn (114.215.172.52) gets hit every time dwang starts, this one looks bad, it's definitely reporting some crap to this site.
also hardcoded in dwang are several hidden pools, I denied all those too based on fqdn.
stratum+tcp://stratum.f2pool.com:3333
stratum+tcp://stratum.haobtc.com:3333
stratum+tcp://vipebite.btcxo.com:3334
stratum+tcp://stratum.btcchina.com:3333

none of those have been hit though, i think they may only exist to auto fill the details , when you go to the miner config webpage it has radio buttons for haobtc and btcchina (but not the other two???!?!?!?) ... but the rule to deny stays! We'll see if they get hit attempts over time

WHen I turned on packet monitor , during dwang startup I've found  they are reporting or trying to report something to:
get ipaddr : 114.215.172.52officail name : e.g703.cn
their_ipaddr =114.215.172.52


that IP.
It comes back to some
Aliyun Computing Co.

It's live, you can ssh there.

Why would people pay for firmware that will just damage the unit? Overclocking asics is just plain stupid. Even if they survive the machine will drop the s7 levels of efficiency. Also it sounds like none of these guys understand how the fan controls work, yet another failure point. Also, $15 per unit for firmware? fuck you.

I think the object was to secure the thing, not so much to overclock it.   They come shipped with admin/admin for the web interface with no way to change it, damn near wide open snmp active,  and no ssh access so you can't administer them enmasse very easily without remote command line access not to mention there is no way to shut them off remotely without ssh, so if you sent your miner to a farm for cheaper power or your away for weeks at a time from your miners and the price of BTC drops dramatically...people want a way to shut the thing off.
I believe I posted many days ago on the very subject of "why do you want to overclock it" and all the caveats with overclocking your asics, and also on the subject of "why do you want to take control of your fans" when the manufacturer seems to have gone through great lengths to keep very specific control on the fans.
But, some people want to overclock and mess with their fans anyway, who is anyone to judge them. Mabey they just want to play, learn, mabey they don't care about efficiency or lifespan,  who knows. It's their miner, they can do what they wish with it.
