Controlling Access to Services
This section describes how to disable services, such as Telnet and Rlogin, for inbound users, which means that
they cannot access the Digi device using those services. This feature allows you to turn off individual services or
to specify a security level, which means that all services not
included in that level are turned off.
Services that Can Be Turned Off
The following services can be turned off.
HTTP
RealPort
•Reverse TCP
Reverse Telnet
Remote login
Remote shell
•SNMP
•SSH
Telnet
Service Levels
These are the secure access levels:
Secure, which means that SSH is the only service available to inbound users
High, which means that SSH, HTTP, SNMP, and RealPort services are available to inbound users
Normal, which means all services are available
Custom, which means you can select services to turn off.
The default service level is normal, which means that all services are available.
