The installation procedure sets up access privileges for the Cisco ANA Gateway and the Cisco ANA Units. These privileges are defined in the .rhosts file of the root account in each machine. These files must remain intact.
The current configuration for Sheer users in all machines is + + which means any user from any machine. If the user's security policy prohibits such promiscuous behavior, then be advised that remote access is required between the Cisco ANA Gateway and all of its Cisco ANA Units in both directions.
If any changes are made to the .rhosts files in the machine please verify (using rlogin or similar software) that access is enabled for the Sheer user from the Cisco ANA Unit to the Cisco ANA Gateway and vice-versa.
