[Guide] Dogie's Comprehensive Bitmain AntMiner S2 Setup [HD]

[jpsmith8488]

Thanks to the advice I have received from those who have contributed to this thread, I have narrowed the problem of non-hashing down to an incompatibility in the addresses of the MacBook Pro, the Internet connection, and the S2 Antminer. I list below the relevant information for consideration:

S2 Antminer
Type: Static
Address: 192.168.1.99
Netmask: 255.255.255.0
Gateway: 192.168.1.1
DNS: 192.168..1.1

The MacBook Pro (connected to the Internet by Wi-Fi):
Configure IPv4: Using DHCP
IPv4 Address: 192.168.168.140
Subnet Mask: 255.255.255.0
Router: 192.168.168.168
DNS: 75.75.75.75, 76.76.76.76

I can easily change the Gateway and DNS on the S2 Antminer. I would greatly appreciate specific suggestions for how to change the settings to enable the S2 Antminer to access the Internet via the MacBook Pro.

Much appreciated.

Justin

Oh man, this is perhaps more complicated that I first surmised.  Are you wanting to use your Ethernet port on your MacBook Pro to feed the S2?  Does your wireless router not have an Ethernet port?  If you can, describe your network for us.

While it's possible to do what you want, it's going to result in a fragile design at best.

The IP address of my Apple Time Capsule router is 192.168.168.62 which is a problem considering that my S2 Antminer IP address is 192.168.1.99. When I try to change the S2 IP address to 192.168.168.63 in the Network section of the GUI, and then select "save & start" the S2 freezes, requiring a restart to regain control. What is the preferred way to change the IP address of the S2 so that it can perform hashing.
Thank you,
Justin

All right-we are getting close:
First off, turn off your macbook wi-fi (it simplifies things)
Then on macbook in network, choose manual (do you have ethernet port? if yes-simple, if not, connect thunderbolt adapter and then in manual choose thunderbolt and NOT ethernet pane), then enter
IP4 192.168.1.254
subnet 255.255.255.0
router 192.168.1.1
DNS 192.168.1.1 (it is perfectly OK to choose the same as router in this case)

<Apply>
use ethernet patch cable to directly connect S2 and macbook.
With wi-fi on macbook still off, turn S2 on (PSU on) or if it was already on, open chrome browser on the macbook
enter 192.168.1.99
you should be in login
root/root
in webgui edit the network

I would choose static, but others disagree

input
IP4 192.168.168.X (X=a number away from your range of home devices, could be 71,81,91, etc). Alternatively, connect your miner directly to Time capsule by ethernet cable beforehand (remember to put it into LAN port, not WAN) and then check what IP is automatically assigned to miner by your network (you can use iNET for this). You can then use this IP number to get X.
Netmask 255.255.255.0
Getway 192.168.168.62
DNS 192.168.168.62

save and apply
wait 5 min (for safety), the "wheel" will be turning.
once you see that miner has a new IP address (it will show on the blue LCD screen)
close the browser
reconnect miner with timecapsule via ethernet cable
power cycle the miner (off, wait 10-20 sec, ON)

turn wi-fi on your macbook on
see if you can connect in chrome to 192.168.168.X (where X is what you have given it)
enjoy

Beware that some recent miners do not accept IP change. If this is the case, download 6/19 firmware to your laptop, then in "system" pane on webgui browse to your laptop download folder, choose the 6/19 tar file and flash it (do not untar the file in the macbook)

Comment: either you made a typo or there is something strange with your network because your macbook has getaway (192.168.168.168) that is different from your router (192.168.168.62) when it should be the same

.... The answer STILL remains to put that S2 into DCHP. That's it, there is no complication.

Interesting S2 behavior on 6/19 version of system software: a "Lazarus" function is active.

Beforehand with my previous S2 once it shut down, it stayed shut down until I power cycled it.

With the last batch version I noticed something different. S2 does shut down on average once in 3-4 days, goes all the way to zero hash for a minute or two, then mysteriously springs back to life automatically. I think that they changed something in software to restore it to "life" automatically (at least my machine behaves like this). This is quite cool if true. Next time your recent S2 miner starts beeping and shows zero hash, don't restart immediately-give it 5 min and see what happens.

Experienced a strange problem but it doesn't seem to affect hashing speed however was worried on resale value.

Fan speeds are all reported at 0 although temperatures are normal and the fans are spinning ok.

I contacted BitMain and they told me to check this:



And lo and behold, the diodes are on the wrong end. Very weird indeed.

I'm waiting to hear what BitMain has to say about that and whether I really need to do anything.

my understanding that you should NOT just burn the image to microSD, instead you have to make the SD bootable, which is a process that takes 20-30 min-see bottom of page 86 on the main S2 thread for EXACT instructions. I did it and bootable microSD 'worked", but you will have to replace pools and also remove known_hosts file (for ssh access) as discussed on this thread.

Can you provide a link to the main S2 thread?

Does someone know specifications of staff fans? Maybe it makes sense to replace the fans with more quiet?

I've seen some estemints that the S1 would be reach its usefulness in November, "meaning it would cost more in power then it could make in a day" … Has anyone seen any estaminets on the S2 ? I know that it somewhat depends on what you pay per kilowatt , but thought there might be a ball park figure… The S2 is under volted in contrast to the S1 so per GHs it draws less power..

I am trying to figure out if and when Bitmain comes out with an upgrade kit to the new less power hungry chip would it be a good idea to make the change. I don't see the point in jumping right on the upgrade train if the S2 in its current state is making money and how far past ROI it is ..

- How do I change the login password?
- Navigate to System -> Administration. Enter the current password and enter your new one twice.

Doesn't work on my S2. It returns a message in red letters "Invalid password" and doesn't change it. Whatever I try, even "123"-"123" as my new password.

That error message suggests you're tying in your current password wrong.

One S2   1TH/s  mine today 0.025BTC
1Kw/h x 24 = 24KW/h  one day
the price of electricity  for S2 one day in my  sountry  is 2,64 EUR

0.025BTC  x 400EUR = 10EUR    Profit 7.34 eur  I currently have a 20 TH/s  20x7,34=
146 EURO profit  in one day   when I would sell BTC , but I do not sell BTC

I hope that the next level of difficulty give me a the same total profit, regardless one S2 miner will then have less of BTC.
Yesterday I bought a 5 AntminerS3  and DHL will bring me one Set of btcgarden-AM-V1 next week. Together  2.8 TH/s   costs 4.25BTC . So I invested BTC in miner.

That error message suggests you're tying in your current password wrong.

Well, I suggest that my current password in miner's web interface is nothing but root. Anyway, I have tried both passwords - root and admin, just to be on the safe side...

What firmware are you on?

[Rabinovitch]

On latest initramfs.bin.SD-Kano-20140611145346.tar from https://github.com/kanoi/cgminer-binaries/tree/master/AntS2.

Ok. AFAIK it was left as a firmware bug. If you're running on a branch I have no idea if its due to it not being fixed in the branch, or that the main was never fixed.

Because accepted is at difficulty 1024 and rej + disc are at difficulty 1. Adjusted you get:

A 141,489,152
R 546
D 3,527,868
=~2.5%

What about HW errors? At which difficulty should we consider it?
