[GUIDE] Mining on Amazon EC2 using Spot instances

[gnarl]

Are people still making a killing with this?
Through various providers, I got a few free VMs to test, some of them have pretty good specs (like on Azure), but I get maybe 5PTS a day... Unless PTS go crazy high I'm not sure how interesting this is... especially when I will have to pay...

What are the things I'm missing to make this profitable?

It was much better a couple days ago when difficulty was 0.000120 instead of 0.000514

Like a hammer to the head.

You can't sudo without a TTY connection therefore sudo on the user-data commands do not working.

Profitability on AWS is very low right now. I shut all mine down. I hope people are doing their math or they will be in for a surprise when they get that bill. It's easy to get carried away trying to mine.

Unless you have a fleet of 1500

then still the ROI would be the same

Works fine from the command line once the system gets started, but doesn't look like its executing when the instance is first starting up.

[gnarl]

Yeah, they are upping the prices and killing my sessions now.
It was fun while it lasted!

Based on my testing it's getting very difficult to get positive ROI when mining on EC2.

Doesn't look like its being executed during startup. Anything else I should do?

First, validate your script by executing it manually as root on a brand new instance. Then when validated, put it as User Data, as you did, and then when the instance starts, log in quick and follow the progress of your commands by listing the processes (ps aux). If that doesn't help, output the stdout/err of your script in some log file.

Can't get the scripts to auto execute when starting up. Any suggestions - adding it to the Advanced details.

Number of instances 1.
Request spot instance checked.
Advanced Details
Kernel - use default
Ram Disk - use default

slicify.com has free servers!

Awesome I didn't know about them, thank you!

I tried slicify.com and everytime I found share always invalid share, reason : Share data time underflow.
Any idea how to fix this?

Yeah, set the time

Thanks but it won't allow me
14 Nov 13:29:07 ntpdate[4504]: bind() fails: Permission denied
and also when saving the cron file, Permission denied
Any idea?

sudo su
apt-get install ntp
then the ntp command from the link

but some of those slicify instances are odd, booked the i7 but that guy got no internet access configured or something, didnt bother to look much further ^^

Nice, No more permission denied, need to try it but ypool is down.

Thanks for the help.
