4. Serial Port, Host, Device and User Conﬁguration

4.2 Add and Edit Users

The Administrator uses this menu selection to set up, edit and delete users, and deﬁne the access permissions for each of

these users.

Users can be authorized to access speciﬁed services, serial ports, power devices and speciﬁed network-attached hosts. These

users can also be given full Administrator status (with full conﬁguration, management and access privileges).

To simplify user set up, they can be conﬁgured as members of Groups. With ﬁrmware V3.5.2 and later, there are six Groups

set up by default (earlier versions only had admin and user by default):

admin Provides users with unlimited conﬁguration and management privileges.

pptpd Group to allow access to the PPTP VPN server. Passwords for users in this group are stored in plain text.

dialin Group to allow dial-in access via modems. Passwords for users in this group are stored in plain text.

ftp Group to allow ftp access and ﬁle access to storage devices.

pmshell Group to set default shell to pmshell.

users Provides users with basic management privileges.

Notes: 1. The admin group provides the admin user with full Administrator privileges. The admin user (Administrator) can access the

console server using any of the services enabled in System: Services (e.g., if only HTTPS has been enabled, then the

Administrator can only access the console server using HTTPS). However, once logged in, they can reconﬁgure the console

server settings (e.g., to enabled HTTP/telnet for future access). They can also access any of the connected hosts or serial port

devices using any of the services enabled for these connections. The Administrator can reconﬁgure the access services for any

host or serial port. Only trusted users should have Administrator access.

2. The user group provides the general user with limited access to the console server, connected hosts and serial devices. These

Users can access only the management section of the Management Console menu with no command line access to the console

server. They also can only access those hosts and serial devices that have been checked for them.

3. If a user is set up with pptd, dialin, ftp or pmshell group membership, they will have restricted user shell access to the

assigned managed devices but will not have any direct access to the console server itself. To add this function, the user must

also be a member of the “users” or “admin” groups.
