60 DSView Installer/User Guide Appendix B: TCP Ports When the DSView Client is launched, the Node Manager will become active. Node Manager will attempt to establish a Security Support Provider Interface (SSPI) Messenger Class session using TCP/IP over port 2068 to the DSAuth Server (Authentication Service).
Appendices 61 After the browse list is returned to Node Manager, the user may double-click on a specific port to initiate a KVM session with that port on the DS appliance. The DSView Client contacts the DSAuth Server, which checks the permissions on the port again.
62 DSView Installer/User Guide Figure B.3: DSView Client Establishing a Session with a DS Unit If the DSView user wishes to establish a session with another port on the DS appliance, the same process is used.
Appendices 63 DSAdmin functions similarly to the DSView Client. It establishes a connec- tion using TCP/IP port 2068, and uses the same process for authentication and return of the browse list. Changes made to the browse list through DSAdmin are transmitted back to the DSAuth Server using TCP/IP port 8190.
