Has anyone figured out a good way to single out a problematic miner in an array of miners?  I rather not have to run them all individually to find the problem child.

Head to www.bittawmart.com to get some of these little beasts ! preorder open

Install screen.
Then once you log in run screen which will just give you a new shell.
Anything you have running in screen will remain running if you get disconnected.
When you have to reconnect just run screen -r and you'll be right back in your previous session.

Here is a question for our Linux/Raspbian crowd:

My plan was to run this off my RPI 3 as a headless system. I can putty in, do admin tasks, start, etc.
Trouble starts when I try to figure out how to log out & leave the pi mining.
Anyone have a good method for this?

I tried some tests with nohup command:
nohup ./startmoonlander.sh &
-
This does load bfgminer in background (with red LEDs flashing),
But not sure how to bring if forward again and worse the mining still stops when I close putty session.

If you are SSH(putty) into a raspberry pi the "Smart" power management may give problems to that connection also..
I'm logging into my RPI 3 "headless" using putty from a Win 7 CPU on my local net. Just got my new sticks running last night *yahoo* - and after my Win 7 CPU "slept" all sticks were not hashing next morning.

I'm running six Moonlander2s on two "Plugable" 7 port Charging/Data Hubs. I inspected the board in these and they DO NOT have three control chips on them. 1,2,3 are on one chip and 4,5,6,7 is on a second. I think these are a newer model where they have planned a cheaper way of making them. We had extra time waiting on shipping so I also ordered six "Y" USB cables, they are 12" long with two male ends - one is Data & power while the other is only power - they both go to a USB female socket for the Moonlander2 to plug in. Hoping I now have up to 3 Amps available for each stick. The RPI is loaded with Raspbian Stretch-Lite. I'm still running stock except for clocking to 756 and raising diff to 256. I WILL be tweaking these up over time.

Is it true that default diff of 128 is best for running one stick and we need to raise this some when running multiple moonlanders (like my example of six)?

Thanks to jstefanop for all your efforts & wish me luck with mining *red-flash* *red-flash*..

Thanks also to Astrali for the Raspberry pi guide - helped me a lot..

Thanks for clearing that up! I'm currently in coinpool.nl and haven't had a single (afaik) stale one! Where hash to coins gave me lots of problems, errors, HW errors and the ML fell completely silent this pool seems to be working just fine.
I'm awaiting two more ML's and another 2 in february , you think around 20 mhs will be better in hash to coins?

I've been getting that but not from minera. Symantec only seems to catch the problem but not solve it. I had to run the Microsoft Windows malicious software removal tool to get it to stop. I think that has been going around he web some.

 I have found a fix for most users that are experiencing issues with the miners just stopping!

 if you use the conf file and you add more than 1 pool the miners will all stop when network difficulty information is gathered from the other pools.

 Fix: set 1 pool in your conf and remove the pool from the cmd/bat file, if you leave the same pool in the cmd/bat file it still treats it like having 2 pools.

my bat file:

bfgminer.exe --scrypt -S MLD:all
pause
exit


hope that helps!

Hi all,

I have a little question about minera.. Every time I go to the website of minera I get this virus pop up from Symantec  "PUA.JScoinminer" are there more people getting this message in there virus program.

Thx. in advance.

With litecoinpool.org is very unstable. With default settings it starts at 3.5MH and after a couple of hours I get 0.1-0.3 MH.

Can someone help me to configure it at maximum? With stable performance?

An other things I got this warning:
I saw a warning: failed to sanity check in lowl-vcom.c windows_usb_get_string():508


Edit:
OS: Windows 10 64Bit

any idea when the driver release may be available with auto-restart? once my hub comes i'm thinking about just loading minera on my raspberry pi but until then...

it will just take 16x as long on average to submit a share to your pool. On average you will be hashing at 4.33MH but if you look short term you'll see crazy swings from like 20MH down to .5MH on pool side.

This is the same reason some newer people think they are not working, because most pools have initial diffs set to 8k or higher for larger ASICS so takes forever to submit first share to pool(or 256k like nicehash had...guess we don't have to worry about them anymore  )

Going to try this out this afternoon, thanks!
Maybe a bit offtopic, or not, but if i'd not specify the difficulty and just leave in password, will it use the default 8192 difficulty?
What would be pro and cons about using 8192 instead of the 512 you mention?

For now it's hashing 4.33 Mhs on 768 mhz

Keep in mind the are not the highest quality fans unfortunately. When I decided to add the fan thermal setup halfway in development I didn't have the funds to buy higher end ball bearing fans. These have a sleeve bearing, which after it wears in has the side affect of increasing the fan speed. They are supposed to spin at 10k RPM, but I have measured some that spin up to 13-15k, so at those speeds they get noisy and vibrate more.

These are so fun... I have no powered hub at all. It works out-of-the-box on my 3.0 laptop port at suggested 600MHz. Only one FB2 connected. 5y old Acer running linux Mint.  No problems whatsoever. Getting about 3,33Mh/s. It even runs on my headless Pi Zero 1.3 running latest stretch lite+zero4U hub+wifi dongle, all powered only by Emtec U500 powerbank(!)... so, I have the first mobile mining unit, not that envion guys...

First you need to register within some pool. Try https://www.litecoinpool.org (your LTC address goes to account settings/Payment address field)
Visit the help section to see how configure miner.

Are you windows user? If so then you just download the bfg miner ( see OP) and you only need to edit the start.bat file. Put in your credentials (username and pass) as per help page on the pool. Everything else you can keep.
If you are linux, i saw some guide few pages back.

Hi "jstefanop"
I need your help if you don't mind.
I'm quite new to mining stuff.
I bought 2 moonlander but I don't know how to configure them.
Can you help me make the setup? I understand that I have to use my wallet address, username, and password.
Can you give me some ideas of other configuration for mining?
As I said, I don't have experience but I want to learn. I already read all the 31 pages of this post, and I didn't find information about that.
I will appreciate a lot your help.
Thanks.

That's a god price they have, but they only allow to order 2 at a time   Problem is that while all prices are quoted in USD it seems you have to pay in BTC? That's a pain. (right now I prefer to hold on to my BTC)

Located in Norway, so shipping costs are bad as they are, import duty is worse. In this country it can only be a hobby. That's fine too. The german distributor (forgot so quickly the name) only sends to EU, not to Norway. They have good prices too but it doesnt help me.

static diff
stratum+tcp://hash-to-coins.com:4444

works fine for mine

d=512 in the worker password field  and  in -p d=512

I've been watching my miner all day and I think you're right about hash-to-coins. They're doing something that's causing the miner to lock up after a while.

I did notice that on the site, it listed the difficulty as 1024. I wonder if their vardiff calculation is bad.

Well, for now I've switched to only mine at mining-dutch. I'm steady at 5Mh/s there.
