OPC UA Interoperability Testing with OpcCmd

This article is mainly for internal usage.

Session

CreateSession() over an insecure channel with UA TCP and SecurityPolicy =None

Example: uaClient read opc.tcp://opcua.demo-this.com:51210/UA/SampleServer i=2255 --EndpointAllowedMessagedSecurity SecurityNone

CreateSession() over a secure channel with UA TCP and SecurityPolicy=Basic128Rsa15 where the key length is minimum 2048.

Example: uaClient read opc.tcp://opcua.demo-this.com:51210/UA/SampleServer i=2255 --EndpointSecurityPolicyDisplayName Basic128Rsa15

ActivateSession() with user identity = username/password

Example: uaClient read opc.tcp://opcua.demo-this.com:58810/GlobalDiscoveryServer i=2255 --EndpointUser appadmin:demo

ActivateSession() with user identity = anonymous

Example: uaClient read //opcua.demo-this.com:51210/UA/SampleServer i=2255 --EndpointAnonymous True

However, the anonymous identity is the default, and as such is used in other tests unless other identity is explicitly specified.

ActivateSession - change user in an existing session.

Not supported.

Use CloseSession() to end session. If possible, verify that the following service calls to the session are rejected.

Create and use multiple sessions.

CreateSession() with an application instance certificate

CreateSession() over a secure channel with HTTPS and SecurityPolicy =None.

ActivateSession() with user identity = X509 certificate

CreateSession() over a secure channel with UA TCP and SecurityPolicy=Basic256Sha256

CreateSession() over a secure channel with UA TCP and SecurityPolicy=Aes128-Sha256-RsaOaep

CreateSession() over a secure channel with UA TCP and SecurityPolicy=Aes256-Sha256-RsaPss
