11.6.4 Disabling the FTP and HTTP Servers

The server contains on-board FTP and HTTP servers. You can choose to disable one or both of these servers
using the Set/Define Protocol FTP and Set/Define Protocol HTTP commands.
Local>> DEFINE PROTOCOL FTP DISABLED
Local>> DEFINE PROTOCOL HTTP DISABLED
If you choose to disable the HTTP server, you will not be able to use the web browser interface for
configuration. You will also not be able to use the URL to find the log file when you receive email
notifications of serial events (see Email Alerts for Serial Events on page 3-3).

11.6.5 Packet Filters and Firewalls

Filters enable the SCS to restrict packet traffic. Each filter specifies a particular rule, for example, only IP
packets will be permitted passage. Packets that pass the filter will be forwarded; packets that don't will be
discarded.
Filters are organized into ordered filter lists, which are referenced by name. For example, a filter named
firewall may permit forwarding of packets that match a particular IP rule, but deny passage to packets that
match a generic rule.
For a complete explanation of filter rules, see Set/Define Filter on page 12-166.
Note:
Filter lists are associated with sites. Sites use filter lists for the following purposes:
Type of Filter List
Idle
Figure 11-45: Configuring Connection Type
Figure 11-46: Disabling the HTTP and FTP Servers
Table 11-1: Types of Filter Lists
Purpose
Determines whether the site will remain active. Packets that
pass the filter will reset the site's idle timer, preventing the site
from being timed out.
