Torsten commented on PLC4X-303:
-------------------------------
Hi [~hutcheb], I have verified at our customer that the patch for an empty
password works as espected.
class org.apache.plc4x.java.opcua.context.SecureChannel#getIdentityToken
{{case userTokenTypeUserName:
//Encrypt the password using the server nonce and server public
key
byte[] passwordBytes = this.password == null ? new byte[0] :
this.password.getBytes();}}
According to Your change "I have added a hostname lookup when trying to resolve
endpoints": we have the situation that the endpoint (configured using an
IP4-Address) sends all available endpoints using a hostname like in this URL
"opc.tcp://br-automation:4840". The client side are not able to resolve the
hostname "br-automation" and no endpoint is selected.
If have modified method onConnectActivateSessionRequest in class SecureChannel
as follow:
1. convert endpointDescription.getEndpointUrl().getStringValue() to an URL
2. compare only port and path ignoring the host
if( String.valueOf( url.getPort() ).equals( configuration.getPort() ) &&
url.getPath().equals( configuration.getTransportEndpoint() ) )
3. remove loop: for (String hostEndpoints : endpoints) {
With that changes an endpoint is selected. Should I open another ticket for
that or miss I something on that point?
