Client Software Requirements

Clients must exist on the same host as CTE COS S3. External Client connections will be rejected by the COS Proxy.

Clients must be AWS S3 protocol aware, and can directly connect to a S3 bucket without the use of an intermediary service, such as the AWS S3 Management Console website.

Clients must be configured to divert outgoing network connection to a COS proxy (default is localhost:3128 or 127.0.0.1:3128). For more information, see Configure the AWS CLI Network Proxy.

Clients must use the TLS 1.2 / TLS 1.3 network encryption protocol over TCP/IP to establish connections to the COS proxy.

Clients must be configured to use the COS CA Root Certificate of the COS proxy to verify and authenticate TLS connections. For more information, see Configure the AWS CLI to use the COS Root CA Certificate.
