IP Services
Certain System Services can be enabled or disabled. They are DNS Relay, FTP, TFTP, SNMP, and the
WEB Server.
The importance of disabling any of these services is an issue of security. If you are not using a particular service,
it is best to disable it. By disabling it, the associated port is not active, which means it is not available to abuse
with the intent of unauthorized access.

WEB Server
The System Service which must be wisely disabled is the WEB Server. After you disable the WEB Server from
the web page, you can no longer access the any of the OnSite device’s web pages. The only way to enable it is
through the Command Line Interface (CLI).
CLI Configuration
After configuring a terminal emulator to access the OnSite device’s serial port, there are two commands for the
enabling or disabling the WEB Server. The following command enables the WEB Server so you can access the
management web pages via a browser. Remember that by only doing this command, the change is saved only in
volatile memory. Be sure to execute the next command to save it in non-volatile memory.
webserver enable
system config save
The next command disables the WEB server.
