Hey guys,

I'm trying to get a version of the Cryptohaze Multiforcer running on a Amazon EC2 cg1.4xlarge.

The new Multiforcer seems to need >= glibc 2.7 which is like impossible to install on CentOS 5.x
An update to CentOS 6 is nearly impossible, too...

Has someone an idea, what other AMI I can use to get that running?

I already tried to compile the old 0.7 but without success...

</snip>

Do I need a distri like CentOS 6.x, Debian wheezy / Ubuntu 12, gentoo?
Can I just recompile the New Multiforcer against a glibc 2.5?

Thanks for any small hint!

You really, really don't want to use the old one. It's a piece of shit.

I was actually running the new multiforcer on the EC2 GPU instance recently.

I ran it on "Cluster GPU Amazon Linux AMI 2012.03" and had no trouble. Push binaries up and go.

The Linux beta up now is old - I need to push a new one.

Try running it on that instance, though. If that's failing, let me know and I'll see what I can do.

The other option is to build it from scratch on your instance following the directions on the wiki - the Ubuntu 10.04 build setup should more or less work on other OSes, you'll just need to replace the apt-get lines with whatever your preferred package manager and package names are.

Alternately, give me a week or so and I'll have some prebuilt AMIs available with all the tools installed & updated.

Hi Bitweasil,

Any updates on the release of the pre built AMI's?

Thanks in advance.

Still on the list - had a very busy weekend hammering on the network code. It'll happen before Defcon!

It works for me out of the box with the new version. Just run

Code: Select all

sudo yum update

and use the AWS console to reboot the instance.

If you start New-Multiforcer, make sure to add

Code: Select all

--noopencl

. At least for me this made the trick.

Please see:

This is directions and a script for setting up the Multiforcer on EC2 cg1.4xlarge instances.
