Description (last modified by dkocher)

Hi All,

I seem to having issue with a upload limit for a IAM user policy it seems to be a cyberduck specific issue because it will upload fine with the browser uploader.

My policy is as follows.

                "Version": "2012-10-17",
                "Statement": [{
                    "Effect": "Allow",
                    "Action": ["s3:*"],
                    "Resource": ["arn:aws:s3:::myusers", "arn:aws:s3:::myusers/*"],
                    "Condition": {
                        "StringLike": {
                            "s3:prefix": ["1/*"]
                }, {
                    "Effect": "Allow",
                    "Action": ["s3:*"],
                    "Resource": ["arn:aws:s3:::myusers/1/*"]

It will allow me to upload small files but limits anything over about 100mb?

Does Cyberduck limit uploads for IAM policies?

  • Resolution set to duplicate
  • Status changed from new to closed

My guess is that the policy is missing the permission s3:ListBucketMultipartUploads action on a bucket to list multipart uploads in progress to that bucket.

Hi Dkocher,

Should it be actioning all permissions in the policy with s3:* ?

Is there a special setting for ListBucketMultipartUploads?
