Can't connect to S3 compatible endpoints

infscape-appliance

Hello,

We are using OVH for our S3 object storage. They have many datacenters around the world, which use different region names than AWS.
Instead of us-east-1, ca-central-1, eu-north-1, etc, they use the following regions names: bhs, de, gra, uk, sbg, waw

In our case, we are using the endpoint: https://storage.bhs.cloud.ovh.net
When we try to connect with the infscape-appliance, it doesn’t recognize “bhs” and assume “us-east-1” instead. Consequently, we get this error:

WARNING: AWS-Client: Encountered Unknown AWSError ‘AuthorizationHeaderMalformed’: The authorization header is malformed; the region ‘us-east-1’ is wrong; expecting ‘bhs’

From our experience, there are 2 workarounds:

  1. specify the correct region name in config files
  2. specify to use Signature version 2 of the protocol (This version doesn’t check the region name)

My questions:

  1. How can I specify a custom s3 region name in infscape-appliance?
    I have looked around and I didn’t find a config file that I could change.

  2. Alternatively, how can I specify to use a Signature version 2?

Thanks,
Claude

This is the second service where this is a problem ( The authorization header is malformed; the region 'us-east-1' is wrong; expecting 'fr-par' ), so adding a field does seem to be necessary.

It’s annoying, because it is redundant information if the service already needs a specific endpoint. The S3 service shoud just ignore the region header.

Thank you for the followup.
I will be glad to test the fix as soon as it gets available.

Will the fix be available in the next version?
We are ready to test !
Thanks.

Got wrapped up in other changes. If you want to test replace the “24” at https://www.infscape.com/urbackup-appliance-download/ with “27”, e.g.

wget https://dl3.infscape.com/images/urbackup-app-9-27.sh && bash urbackup-app-9-27.sh

Thanks for adding the “Override S3 region” field.
We can now specify the proper region name.

Urbackup now works perfectly with our provider S3 storage service!
