so vsm server it is used to assign user grants on cluster, management of session, etc.
Yes.
vdm agents are instead the hosts on which I would connect.
The server(s) running vsmagent is where the actual session will be started and kept, i.e. your desktop environment.
ok perfect, so with host_aliases I can use the same ip address (on public side) with differents ports to reach out the internal vsm agent? perfect, I will try this.
Correct.
