[ANN] FarmCP - Web-based Rig Control Panel on your rig (Linux, BAMT)

[mrbrdo]

Hello guys,

I want to share a little dashboard I've made for my farm. I am using BAMT 1.3 on my rigs, but the web interface was not good enough, I wanted to at least be able to switch pools without sshing to each of my rigs.

Features:

* only need to install on one of your rigs
* works on any Linux-based system
* open-source and free
* pretty cool dashboard on which you can monitor all your rigs hashrate, temperature and rejected shares
* ability to add a pool to all of your rigs at the same time, and switch pools on each rig
* anyone can contribute new features (Ruby on Rails project)

Let me know if you find it helpful. Security audit welcome, some people are always paranoid
I will also probably implement a simple API, which will be supported in my iOS app (Android coming soon).

If you like it, please post a comment and spread the word. Or if you have any problems, let me know as well.

Someone just sent this link to me. This looks very cool. I'm going to review the code then give it a try on my ubuntu rigs this weekend.

[roastbeef]

Code looks pretty decent. I left a couple comments, but found nothing suspect. This looks clean as of 1/31 11PM CST.

[mrbrdo]

Thanks. I did a bit of refactor as per your comments, so code should be cleaner now.

Added profitability calculator. You can enter difficulty and reward manually or fetch it from a MPOS pool website (most common pool web interface).

installation instructions:

Looks nice, but apparently SMOS doesn't have rvm..

user@smos-1:/tmp$ rvm install ruby-2.1.0
-bash: rvm: command not found

Any suggestions? I'm not that good with Linux..

[mrbrdo]

Instructions for installing rvm are already written in README, maybe you missed it: https://github.com/mrbrdo/farmcp/blob/master/README.md
Start at first line (sudo apt-get install curl)..

Also if you are using SMOS or BAMT you might need to plug your usb into some Linux (e.g. Ubuntu) machine (also Virtualbox works) and use GParted to resize the ext4 partition. Because at least on BAMT 1.3 there is only a few MB of space left and this is barely (if even) enough to put farmcp there.

You can check if you need to do this by writing "df -H", find the line that starts with "aufs". Check under "Avail" column, if it says only a few MB then you will probably need to resize. If it is at least 200MB or several GB then you're good.

PS: Are you aware that on SMOS you are mining LTC every day for that serbian guy (at 3 AM in the night...)?

(I am a jquery/php/perl guy myself, haven't got into ruby though)
Great addon, I was installing it on my debian linux box and I am trying to have it connect to my remote cgminers.

miner.php that comes with cgminer is working properly so I know I have the remote cgminer api's setup right, but when I run this script locally, it doesn't show any of the miners.

This is my local config for ~/.farmcp

{

"username" : "user",
"password" : "pass",
"rigs" : [
  "192.168.0.4"
]

}

(fake ip)

(through debugging the json calls)
I see it calling this script:
http://192.168.0.3:8080/data.json  (the server running farmcp is different than the actual farm)

and the response is:
{"btc_value":{"btcde":604.7862170362157,"bitstamp":817.308697879499},"rig_info":[],"rig_overview":{"temp":0,"fan_p":0,"mhs":0,"accepted":0,"rejected":0,"max_temp":0,"max_fan_p":0}}

SO it is reply with 0 rig info meaning its not reading the local config file, even though it asks em for a password when I first login (and the username and password works)

I have the latest git pull from https://github.com/mrbrdo/farmcp/blob/master

Let me know, I am trying to look around the code to see if I can find the issue (curl is working fine on the box from the prompt)


EDIT: I think I need to revert the git pull to before the refactor, I think im seeing the missing rig parser from the config file.

Can this be setup on web-hosting rented from  somewhere and just pointed at CGMiner via API?

[gsupp]

This looks awesome! Any chance of adding per-rig management of pools? I'd like to be able to add/remove/switch pools on a per rig basis, ideally with a way to group rigs together and make changes on a group at a time.

[soothaa]

This looks awesome! Trying it out now!

[crazyates]

Does this need to be run on a miner, or can it be installed on any linux machine on the same network as the miners?

[soothaa]

Does this need to be run on a miner, or can it be installed on any linux machine on the same network as the miners?

I've got 3 instances of it running on my monitoring VM - just needs to be able to access the JSON RPC of cgminer.

[Nachi888]

I've started with 700MB available and it still ran out of space.

can u check if anything went wrong?

SO it is reply with 0 rig info meaning its not reading the local config file, even though it asks em for a password when I first login (and the username and password works)

Sounds to me like you don't have api-listen and api-allow set properly? If farmcp cannot connect to your cgminer RPC then something like this will happen. The info on how to set it up is in the readme.

[mrbrdo]

Can this be setup on web-hosting rented from  somewhere and just pointed at CGMiner via API?

Yes, but you need to open cgminer RPC to the IP of that server. That is actually exactly how I had it set up before on coin.mrbrdo.net (still works but old version).

This looks awesome! Any chance of adding per-rig management of pools? I'd like to be able to add/remove/switch pools on a per rig basis, ideally with a way to group rigs together and make changes on a group at a time.

This is already implemented, you can add a pool to all rigs, and switch pools per-rig. I will add more features for this later probably.

Does this need to be run on a miner, or can it be installed on any linux machine on the same network as the miners?

It doesn't need to run on miner, it can run in local LAN or even on remote server if you open ports and set api-allow correctly.

I've started with 700MB available and it still ran out of space.

can u check if anything went wrong?

At the end it shows that you have no space left.. So it seems you need even more space. Weird, but it seems so.
It is a bit weird because I was able to install on BAMT without resizing partition initially. But perhaps there are temporary files it needs while building and you run out of space while installing. Try running

Code:

rvm cleanup all
bundle install
script/puma start

[wangzr1991]

When I tried to restart it,
it shows:
user@bamt-miner:~/farmcp$ sudo /etc/init.d/puma restart
Restarting Puma rack web server: puma--> About to restart puma /home/user/farmcp:Connection refused - connect(2) for "/home/user/farmcp/log/pumactl.sock"

What should I do?

[softron]

Cool app will try this

[kupan787]

Can anyone with BAMT up let me know the contents of their /etc/apt/sources.list file? I was modifying mine to try and get something else working, and can't install this as it can't find dependencies.

Edit: Nevermind, I just extracted the file from a base install of BAMT. I got this up and running now.

[kupan787]

Any chance you can add in display of the WU as well as hash rate?
