Re: The driver received an unexpected pre-login response

Hello GuruprasadNijal

At this point the ePO server is not involved, im not an expert with the Arc-sight Connector but i assume it is attempting to communicate to the SQL DB and it fails with that error, if that’s the case then i can suggest testing the connection from that Device back to the DB, we do have an article that explain how to use the Microsoft test.udl file to test the connection from a windows machine:

but if the connection fails from the Arc-sight device then i can suggest to contact their support so they can review the mentioned error

Hello Aguevara,

As suggested we had tested connectivity locally and found port was the issue.

After changing the port in Arcsight parameter we are getting below error(Read timed out error).

Please check if you any solutions let me know.

Error which we are receiving currently:
Connector table parameters did not pass the verification with error [; nested exception is:
java.net.SocketTimeoutException: Read timed out] for connector [McAfee]. Do you still want to continue?

 

Regards,

Guruprasad

Hello GuruprasadNijal

It sounds like still there is something interfering on the network, particularly because of the SocketTimeoutException message, maybe a wireshark trace will help identify why there is a time out, if nothing can be found I can suggest you to please contact Arcsight as they will understand better what is required and their error codes
