Any advice on how much ram is needed?

Its a CPU miner, not GPU

Yes I'm aware of that. Is there a good rule of thumb as to how much ram is needed? Does the amount of threads (CPU cores) increase the amount of ram required?

configure: error: in `/root/maxcoin-cpuminer':
configure: error: C compiler cannot create executables
See `config.log' for more details

I wish we had a pre-compiled version...

it doesn't want to work for me.

I made sure every single command syntax was right up until then.


I seems to also say

cpu-miner.c:36:21: fatal error: jansson.h: No such file or directory
 #include <jansson.h>
                     ^
compilation terminated.

Hm... I tried with another set of instructions to get a basic scrypt minerd on there and even it has issues with executables:

I'm going to have to ask them for a refund in the morning. What a shame.

That is CFLAGS="O3" ...

made a vid, hope this helps.

(no swap created in the vid but a separate user. If you run a vpn/dedi you might want to disable ssh for that user, and consider if sudo rights a necessary.


EDIT: i recognized the quality is very bad, for some strange reaso youtube is not converting to HD even if the video is HD, i redo it tomorrow eventually…

try this. I am ubuntu. This works fine.

cd maxcoin-cpuminer
sudo apt-get install -y build-essential libjansson-dev libcurl4-openssl-dev unzip automake autoconf
export OBJECT_MODE=64
./autogen.sh
CFLAGS="-O3 -msse2 -march=native" ./configure
make

Ah, this was the problem.

zip md5 = 59df705900e78c52c989ceb08dc55bb6
Make sure to check the md5 to be the same as the file on maxcoin.co.uk! I mirrored the official file on dropbox in case the official site should be ddosed, but you may check this exact md5 hash to confirm this yourself.

In step 11b, how do I check the md5 value? What do I type?

In step 12, I type screen and get the following error. What do I do?
bdarnell@BillsMiner:~/maxcoin-cpuminer$ screen
Cannot open your terminal '/dev/pts/0' - please check

All you have to do is copy paste.

is this guy come from MaxCoin dev teams? can his maxcoin-cpuminer be trusted? is this official miner from MaxCoinProject dev team or not?

As you can read in my guide I am not affiliated with the MaxCoin dev team. The cpuminer was downloaded directly from the official site, md5 sum 59df705900e78c52c989ceb08dc55bb6 / As stated in the guide you can and should confirm this yourself. Apparently the file has been temporarily removed from the maxcoin site, it was available yesterday for many hours. (https://twitter.com/stacyherbert/statuses/431181082310897665)

In step 11b, how do I check the md5 value? What do I type?

md5sum maxcoin-cpuminer.zip

@all: To all experienced with droplet mining before. Is it better to use 1 droplet with 8 cores or 4 droplets with 2 cores?

Anyone has measured the difference?

first time for me and I'm thankful for the guide!
On OSX do i want to run the Digital Oceans console access or do i want to run in terminal?
I have no experience with either.

all you need is Mac OS X's Terminal.app

Hello first off thank you but I'm definitely a n00b as well stuck at step #8...

I was able to add another USERNAME, but a little confused by how to enter in this next part

echo 'USERNAME    ALL=(ALL:ALL) ALL' >> /etc/sudoers

Is this all one line, also, what do you mean by the symbol ' ?

for instance, one line each:

Code:

adduser econcrypto5
echo 'econcrypto5    ALL=(ALL:ALL) ALL' >> /etc/sudoers

hmmm not quite sure the problem

bash: /etc/sudoers: Permission denied

Your sudoers file is broken, you most likely didn't execute the right command syntax earlier.

You will have to destroy your droplet and start again.

k thats what i thought just wanted to make sure will try now thanks again

No problem, if you run into errors just post them here and you'll be helped

so this is what i got...

maxlegendary7@maxlegendary6:~$ sudo dd if=/dev/zero of=/swapfile bs=64M count=16sudo: >>> /etc/sudoers: syntax error near line 31 <<<
sudo: >>> /etc/sudoers: syntax error near line 31 <<<
sudo: parse error in /etc/sudoers near line 31
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin

Unfortunately you still have a syntax error in your sudoers file. Make sure that you don't put it elsewhere first so the encoding of ">>" doesn't change.

Code:

adduser xxx

Code:

echo 'xxx    ALL=(ALL:ALL) ALL' >> /etc/sudoers

You have to put it EXACTLY the same as this, copy and paste it. It works.

PS. You might as well skip this step and run your mining op as root.

From cbuchner1's cudaminer

The new keccak code seems faster than a CPU I think.

Q9550 @3.4 Ghz (one core)
minerd-maxcoin --algo=keccak --benchmark
1151 khash/s.

i3-4130T @2.90GHz (one core)
minerd-maxcoin --algo=keccak --benchmark
599.59 khash/s.  (?? must be a fluke, lots of stuff running on this machine)

Celeron G1630 @ 2.80GHz (one core)
minerd-maxcoin --algo=keccak --benchmark
1020 khash/s

GTX560-448
cudaminer --algo=keccak -d 0 --benchmark -L16 -l F14x16
28468 Kh/s

I could not get cudaminer to run on my Quadro 295NVS. Not sure of the kernel parameters, it wouldn't start (not that I would want to run on this card anyway).

you all know you're doomed with you CPU farms xD
