SSL connects to MQ using .net mq SSLV3 client?

Question

I am currently having a problem connecting to the server due to the following problem:

When I tried to connect to the server, it returned an error: MQRC_SSL_INITIALIZATION_ERROR

After a more thorough analysis through WireShark, I found that the Client is trying to connect to the server using SSL v2 , while the server can only accept SSL V3 , thereby rejecting the connection.

I checked the document, but I can not find any information about which version of SSL the .Net client supports.

I would like to check if the SSL version is controlled from the .Net MQ client, and if so, how can we configure it to connect via SSL v3?

Thanks.

I am not sure I agree with your conclusion, as WMQ supported SSL V3.0 and TLS V1.0 since at least V6.0 and, possibly, earlier. It is rather a configuration mismatch between the client and server. The recommended procedure for resolving SSL / TLS problems is as follows:

My method for debugging SSL connections in WMQ should go through the following sequence so that each step works before moving on to the next:

• Get a channel without SSL. This confirms that the channel names are spelled correctly, that there is a QMgr listener between the endpoints, and that the client points to the right port. You would be surprised how many times someone incorrectly enters a port or channel name.
