User Models and User Permissions in Digi Connect Products
The user model in a Digi Connect product influences the commands that
users can issue. There are three user models implemented in the various
Digi Connect and ConnectPort devices: one-user model, two-user model,
and more than two-user model.
Identifying the User Model for Your Digi Connect Product
To determine which user model is implemented in your Digi Connect
product, issue a “show user” or “set user” command (see "show" on page
249 and "set user" on page 220). In the command output, note how many
user IDs are defined: one, two, or more than two. You can also issue a
“set user ?” command and note the range for the “id=” option. If the “id=”
option is not listed, there is one user. Otherwise, the range for user IDs is
displayed.
One-user Model
In the one-user model, by default there is no login prompt, and the default
name for user 1 is “root.”
To enable the login prompt, you must issue a “newpass” command with a
password length of one or more characters (see "newpass" on page 51).
Once a password is enabled, issuing a “newpass” command with a zero-
length password will disable it.
• User 1 has a default name of “root.”
• User 1 has permissions that enables it to do all commands.
Permissions cannot be altered.
Two-user Model
• User 1 has a default name of “root.” This user is also known as the
administrative user.
• User 1 has default permissions that enables it to issue all commands.
• Permissions for User 1 can be changed to be less than the default root
permissions.
• User 2 is undefined. That is, it does not exist by default, but it can be
defined.
• When defined, User 2 has a limited set of permissions, defined by the
“set permissions” command (see "set permissions" on page 157).
• Permissions for User 2 can be changed to be either greater than or less
than its default.
More than Two-user model
User definitions are exactly the same as the two-user model, with the
addition of user groups and more users. The “set group” command defines
user groups (see "set group" on page 115).
