User Access ControlSECURE CONSOLE SERVERS
2.4 User Access Control
Access to a Port is controlled on a per-user basis via a user profile, which is stored
as a file on the local SCS. This profile is created by the root user using the command
‘adduser’. See Section 8.1.1, adduser, on page 68.
2.4.1 User Sessions
Each SCS supports up to 250 simultaneous user sessions. This is possible since a
user can generate multiple sessions. This number of sessions is perceived to be far
greater than would be needed in most SCS product applications.
2.5 Port Buffers
The Secure Console Servers provide real-time serial port data buffering. Each Port
buffer stores up to 256 KB of data in a buffer, held in RAM in a separate file. This
provides hundreds of pages of port data for each attached device, which can be
reviewed at a later time. The data may be viewed while users are not interacting with
the attached port. Port buffers are enabled by default.
