Comment 7 for bug 688773

@Mathias,
  testing requires that you have an ec2 (or UEC) account set up.

If you did have access to an AWS secret key and access key, recreating would look like:

$ cat > .eucarc <<"EOF"
aws_access_key="AAAAAAAAAAAAAAAAAAAA" # your key here
aws_secret_key="BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB" # your key here
EC2_URL=https://ec2.amazonaws.com
EC2_ACCESS_KEY=${aws_access_key}
EC2_SECRET_KEY=${aws_secret_key}
EOF
$ euca-describe-instances
SignatureDoesNotMatch: The request signature we calculated does not match
the signature you provided. Check your AWS Secret Access Key and signing
method. Consult the service documentation for details.
