Configuring a policy configuration file
This section provides steps to access the policy.cfg files. For information on
modifying a particular action, refer to the sections the follow this procedure.
1 Connect to the Sidewinder G2 using the Admin Console and select File
Editor. The File Editor window appears.
2 Click Start File Editor and select File > Open. The Open File window
appears.
3 Select the Firewall File radio button. The Open File window appears.
Each burb on Sidewinder G2 has a policy.cfgSMF file associated with it,
allowing you to configure different actions for different burbs on the
Sidewinder G2. To distinguish among files, the corresponding burb index
number is appended to each file (for example, policy.cfg.SMF1 is the configuration
file for burb index 1).
4 Type the following path in the File field:
/etc/sidewinder/authority/policy.cfg.SMFn
where n is the corresponding burb index for the burb you want to configure.
5 Click OK to open the file. The policy.cfg.SMF file for the burb you selected
is displayed.
Actions that are commented out (that is, the first character is a # sign) are
disabled. To enable an action, remove the # signs. To modify a particular
action refer to the previous sections.
About the ADDHEADER action
The ADDHEADER action will apply a new text header line to the message. The
new header can then be used as a flag to sort or discard messages that
contain that header text. The following two configuration options can be used
with this action:
• header—This option allows you to specify the text string that will act as the
name of the questionable header. The default value is X-SPAM.
• value—This option allows you to include the threshold value in the header.
The syntax for this option uses standard C language expansion syntax. The
only syntax supported for this option is %p%%. At run time, the %p portion
of this option is replaced with the specified threshold value and the %%
portion is translated to a single % sign.
The following is an example of a ADDHEADER action that will add a text
header of “X-SPAM **%” to the message:
threshold=**%;action=ADDHEADER;config=[header=X-
SPAM;value=[%p%%]]
