6.2. User Specific Configuration

The  purpose  of  the  User  Specific  Configuration  mechanism  is  to  provide  a  higher  degree 

of customization and functionality. It allows the sytem administrator to define ESETS antivirus 

scanner parameters based on the user who is accessing file system objects.

A detailed description of this functionality can be found in the esets.cfg (5) man page; in this 

section we will provide only a short example of a user-specific configuration.

Here, the 

esets_smtp

 module is used as a content filter for MTA Postfix. The functionality of 

this module is based on the [smtp] section in the

 

ESETS

 

configuration file (esets.cfg). See below:

   

[smtp]

   

agent_enabled = yes

   

listen_addr = ”localhost”

   

listen_port = 2526

   

server_addr = ”localhost”

   

server_port = 2525

   

action_av = ”scan”

        

To provide individual parameter settings, define a ‘user_config’ parameter with the path to 

the special configuration file where the individual setting will be stored. In the example below, 

we create a reference to the special configuration file ‘esets_smtp_spec.cfg’, which is located in 

the ESETS configuration directory

.

 See below:

   

[smtp]

   

agent_enabled = yes

   

listen_addr = ”localhost”

   

listen_port = 2526

   

server_addr = ”localhost”

   

server_port = 2525

   

action_av = ”scan”

   

user_config = ”esets_smtp_spec.cfg”

        

Once the special configuration file is referenced from within the [smtp] section, create the 

esets_smtp_spec.cfg file in the ESETS configuration directory and add the appropriate individual 

settings. The esets_smtp_spec.cfg file should look like this:

   

[[email protected]]

   

action_av = ”reject”

        

Note that the section header identifies the recipient for which the individual settings have 

been  created,  and  the  section  body  contains  individual  parameters  for  this  recipient.  This 

configuration  will  allow  all  other  users  attempting  to  access  the  file-system  to  be  processed 

normally. All file system objects accessed by other users will be scanned for infiltrations, except 

for the user [email protected], whose access will be rejected (blocked).
