Hi,
I face an issue with econe-describe-images and EC2 tools access. I have an
authentication error.
Following a previous mail I 've seen (see below), I updated encoding to
HmacSHA256 and EC2QueryServer.rb not to include port for version 2010-08-31
However I still have the issue.
I tried with econe-describe-instances -K osallou -S XXXX -U
http://localhost:4567, still fails
As a client I use ruby gem amazon-ec2.
I check EC2Query ruby codes in repository to see if changes were made but I see
no difference.
Thanks
Olivier
Hi! I discovered an AUTHENTICATION PROBLEM when using EC2 Tools
provided by OpenNebula.
On client-side, the HMAC algorithm used is "HmacSHA256" while the
passed parameter is "HmacSHA1" in
$ONE_LOCATION/lib/ruby/cloud/econe/EC2QueryClient.rb:144
this causes an authentication failure.
I found another problem in the file
$ONE_LOCATION/lib/ruby/cloud/econe/EC2QueryServer.rb
While the issue disappeared executing the tool
econe-upload
it is still present in the tools
econe-register
econe-describe-images
This may be caused by the file
$ONE_LOCATION/lib/ruby/cloud/econe/EC2QueryServer.rb
where, in the function "signature_version_2()" definition, the
variable "server_str" depends on the tool executed.
1. econe-upload
server_str = FQDN
2. econe-register
server_str = FQDN:PORT
I think the issue is caused by the missing parameter "Version" which
is not passed in last two utilities.
Best,
PAOLO
