Connecting to ARCC S3

Once a bucket has been created and ARCC has provided the Access key / secret key combo, connections to ARCC S3 can then be initiated with either an S3 client or programming language package.

S3 Clients

The S3 protocol requires a client to connect to the server. There are a variety of Graphical User Interface (GUI) and Command Line Interface (CLI) clients that can be used to connect to ARCC's S3 service. ARCC has tested a subset of these clients:

Client Name	Operating System	GUI or CLI	Free?	ARCC recommended/supported
MSP360 Explorer (Cloudberry)	Windows, macOS	GUI	Yes, but larger transfers will require a license	Yes
Cyberduck	Windows, macOS	GUI	Yes	Best Effort
Transmit	macOS	GUI	No	Best Effort
Dragon Disk	Windows, macOS, Linux	GUI	Yes	No
rclone	Windows, macOS, Linux	CLI	Yes	Yes
s3cmd	macOS, Linux	CLI	Yes	Best Effort

Scripting/Programming Packages

Some programming languages provide software packages that can use the S3 protocol for accessing data. ARCC has tried a few of these and are detailed in the table below.

Package Name	Language	ARCC Tested
boto3	Python	Yes
aws.s3	R	Yes
AWS	C#	No
