Hello im wondering if anyone could help me out. I've bought an ebit e9 plus before and had no problems, set it up relatively easy within 10mins was all working fine hashing at 9th etc.

I placed another order of 10, some units are working fine but i have several that when fully connected same as the working units i can't find an i.p at all. Nothing appears through my router and i've tried using an i.p scanner to find it as well but to no avail.

Kind of lost on what to do now and any help would be great!

Install wireshark on a laptop, connect laptop network port to miner network port, call up wireshark and the arp messages will tell you what ip. Change your laptop network to a different address on that found subnet, connect to miner webui, change ip to what you want.

Thankyou so much! worked like a charm!  Cheesy Cheesy

Honestly, I do not recommend to deal with Ebit at all. Now I understand that it was my huge mistake to transfer the payment to Ebit. I dealt with cannan and bitmain before and they are far ahead of these crooks.
I placed the order with Ebit for the November batch, transferred the requested amount and it took some patience to get payment confirmed by Lynn through Skype. When the shipping date approached, I contacted Lynn again to confirm the tracking number, but none replied for 3 days and I dialed the hotline. They connected me with Lynn and she said there-there is no miners to be shipped because they are out of stock! I kindly asked her when they would be available and she replied that has no clue when they would be available again! She said if I do not want to wait, they can transfer a refund and I agreed to it.
Now, for almost a week she was replying by skype requesting my bank details etc but no reply on when the refund is going to be processed! That is really a ponzi company without proper customer support. Again, I have dealt with Chinese companies a lot, but such a bad experience the first time...

I especially like the way the clock resets to midnight on July 21st 2010 everytime you reboot.
What kind of epoch is that and why is it starting from epoch every time?!??!?!?!?

DON'T DOWNLOAD ANYTHING without VIRUS scanning if before install!  Don't trust anyone. I made the MISTAKE of donating to one of these so called hackers (punk-ass crook who needs a fractured skull) (not smartass11 BTW)  Got a nice pile of malware.  Avoid promises of delivery based on donation up front.  It's a scam/hoax/malware/bullshit.  You've been warned.

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.

Stop buying industrial miners, running them at home, and then complaining about the noise.

Try it for free, your rep is good enough for that. If you think than that this work doesn't deserve some fee - okay than.
There is only ability to overclock, and ssh added - for everything else you decide how to use.

And you always can keep using second bank

As for proof against unit damage etc - I recorded video with ebit e9+ updating using this FW
https://drive.google.com/file/d/1-1HbVozjc4P5d9ybRoF7bphFoJIvQG57/view

And sadly to hear such words since I also provided detailed steps how to get that access yourself without any fees. But it takes time per unit and requires some skills (you can ask how much that cost in any laptop/cellphone repair shop)


About fans. they are controlled directly by miner software (it is separate module), not by linux OS
all I understood - in latest FW (40, 42) they try to keep temp around 60C for the hottest board (this value is set in one of config files)
to control fan speed on your own I see 3 options
- keep using existing control, play with available settings
- rewrite and rebuild own cgminer (very hard work in general)
- external control (detach blue wire for max cooling, buy/develop some 555-based michrochip circuit and attached it to the wire)

more about access, what you get as a user:
- ability to upload new FW even with broken UI
- ability to restart unit remotely
- ability to change webUI password
- ability to restart just hanging UI
- secure it little bit if you want (snmp, firewall etc)
- explore things if you are a little bit familiar with linux

say thanks:

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.

It is always good to do some R&D, just make sure the equipment has costed you some money and there is a lot to be made out of the devices.

Quote from bitmain:

"We hereby declare that this function is designed for those mine workers who trust their miners to a mining plant, to allow them to remotely shut down miners when miners are stolen or detained without permission, and meanwhile to provide tracing clues to the law enforcement agency. Just like the function of remote removal and shutdown provided by many smartphone manufacturers, Bitmain will never employ the function without miners’ permissions. This feature is especially important when thefts or mine staffs’ delinquency happen in mining plants."

I already found similar code in the ebang miners and posted it to the forum.

Smartass11 is only asking for $15 and actually provides something useful. AVOID TEKCOMM - he is a threat to you and your miners. He's a blackhat punk hacker who poses as being helpful - asks for $50+ to install his "honest mistake" malware so he can steal from you some more. Then gives grade school bullshit excuses and after he gets paid.  The very definition of a SCAMMER.

All, there is no need to pay someone for some fancy firmware, put your miners behind a statefull firewall like an ubiquity edgemax ($70) and just block all inside to outside ip connections that have nothing to do with the pool you are using. Manage your miners via an encrypted vpn (ubiquity supports ssl and ipsec) and you are golden.

Actually if you are running miners behind some NAT (in internal network behind router) - you don't need to worry about firewall I think

You may worry about china soft itself (inbound connections that cgminer make) - for example there are china pools hardcoded for sure

Just now ssh is just very very handy way to manage your miners remotely. And some insurance for cases when WebUI went down.
May be some more things and modifications will come in future (like nxsub support or fan control)

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.
City:
   Hangzhou
Country:
   China

It's live, you can ssh there.
I made a policy on my main router to send that address to oblivion.

I created FW based on 6.0.20.40. You can download it here
https://www.dropbox.com/s/f05u5oantyk45ki/btc_upgrade_6.0.20.40_mod_root.tar.gz?dl=0
https://drive.google.com/file/d/1IxlJSVQ9RT4VQ7gMhDwIjdOo6MH-4p1Z/view?usp=sharing
please double check sha1hash after downloading
b3a851093dc13eafe3e0f48bc0f2557c21ad2267  btc_upgrade_6.0.20.40_mod_root.tar.gz

I see unclaimed root password changes. Don't be shy, ask for them in PM or here (provide mac address and time you rebooted your miner after flashing)

Yes you should. These things are shipped with a firmware that is basically a black box, it makes a connection from the inside to the outside. There is a very big misconception that NAT is a security feature

I meant that nobody can control your miner using web/ssh/snmp behind NAT

Of course SW you have running inside OS behind NAT can connect somewhere and after that receive commands

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

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!?!?!?!?

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.
