Oops. Figured it: Download ‘elb*’ tools from here:

(as you specify on your next post. Thanks!)

Very dumb newbie question:

Where do the commands that start ‘elb*’ come from, e.g. ‘elb-create-lb’ (this is for creating an AWS LoadBalancer.)

I’ve downloaded the command-line tools in ‘ec2-api-tools.zip’, but all the executables in the bin directory there start with ‘exc2′. So all my’ec2*’ commands work just fine:

> ec2ver

I’m on Windows.

This is a outstanding article, I located your blog checking yahoo for a related topic and came to this. I couldnt find to much other info on this posting, so it was nice to discover this one. I probably will end up being returning to check out some other posts that you have another time.

Wow, thank you, spent hours on AWS site, just trying to find something to assist, and your instructions worked a treat.

Once I got the paths sorted of course

Thanks

Dave,

If your using cygwin then you would want to follow Unix based instructions. My instructions here are with the assumption you will use the windows command prompt (aka a DOS prompt).

Thats funny I don’t have the cmd version but it was working the other day without any issues.

I think what happened is that when I first setup my environment I installed cygwin and that installation set up the right conditions but didn’t persist them so that when I rebooted everything stopped working.

This is workign for me for now, but I will take your advice and update the tools soon.

C:\Users\dave>bash ec2-describe-regions
REGION eu-west-1 ec2.eu-west-1.amazonaws.com
REGION us-east-1 ec2.us-east-1.amazonaws.com
REGION us-west-1 ec2.us-west-1.amazonaws.com
REGION ap-southeast-1 ec2.ap-southeast-1.amazonaws.com

Mostly solved!

First issue is that my OS is not recognizing the bash scripts as scripts. If I type:
c:\bash ec2-describe-regions

It ran the script and provided the information I need to move forward. When I ran the script it told me that I needed to use unix stlye delims (eg. / vs \) in my paths.

Eg.
EC2_HOME=c:/ec2-tools
EC2_CERT=
EC2_PRIVATE_KEY=

For now I can specify bash directly but it would be nice to be able to set the file association up again.

Dave,

The bin folder should contain a file called ‘ec2-describe-regions’ without an extension and another file called ‘ec2-describe-regions.cmd’. If you don’t have the cmd files then I would download the API again and unzip again.

Just as a follow up. The problem I am having is not path related because even if I specify the fully qualified path I still get the error. The trouble is not that it can not find the ec2-* files but that it does not recognize them as command files.

The error I am getting is what you would get if you just typed “bob.txt” at a cmd prompt.

‘bob.txt’ is not recognized as an internal or external command,
operable program or batch file.

So I wonder what I did before to get the OS to recognize all those ec2- files as command files. They are bash scripts right? When I run bash at the cmd prompt it loads fine so my cygwin setup seems to be fine.

could it be the declaration at the top of ec2-cmd?
#!/usr/bin/env bash

Looks like a comment but is it?

Hi thanks for your post. I am a bit frustrated because I had my environment setup and working but after a reboot things seem to have come undone.

I am getting the “‘ec2-describe-regions’ is not recognized as an internal or external command” error.

The thing is I am sure that all my paths are correct. I dropped a boo.bat file in my %EC2_HOME&\bin folder and when I run boo, it find it and runs it. When I run java -version it responds correctly as well.

It seems to me that it might be a file associatation issues? None of the scripts in the ec2_home\bin have extensions, so how does windows know to run them with java?

set JAVA_HOME=”C:\Program Files\Java\jre6″
set EC2_PRIVATE_KEY=E:\EC2\ec2-keys\pk-[[snip]].pem
set EC2_CERT=E:\EC2\ec2-keys\cert-[[snip]].pem
set EC2_HOME=C:\Apps\ec2-api-tools-1.3-51254
set PATH=%PATH%;%EC2_HOME%\bin
