Portserver Security - Digi PortServer/8 User Manual

PortServer Security

The PortServer has four basic security access levels:
Root login
This allows complete access to everything. The root user can write and save any of the con-
figurable parameters for any port.
This login is always present, and must always have a password. It is not possible to remove the
root user entry, or delete the root user password.
Regular user login
Except for parameter changes to his or her own PortServer port, a regular user cannot configure
any of the PortServer parameters.
If the "write" option is turned on for a user's port, the user can save those parameters to become
the default parameters the next time anyone logs in on that port. If the "write" option is off, only
the root user can save port settings.
A regular user can temporarily gain root privileges through the admin command if that user
knows the root password.
This is the most common way of logging into a system. These logins identify a user by name,
restrict access by password, and provide access to the PortServer command line after login.
Example:
User login w/o password
This is similar to the most common method, but saves the user the step of entering his or her
password. This is mostly useful in small, secure environments that do not have dialup ports.
Example:
set users name=george passwd=on
set users name=george passwd=off
