3.7.2 The config Directives
The config directives in the snort.conf file allow a user to configure many general settings for Snort. Examples include the location of log files, the order of apply- ing rules and so on. These directives can be used to replace many command line options as well. The general format of applying a config directive is as follows: config directive_name[: value] Table 3-6 shows a list of directives used in the snort.conf file. Table 3-6 Snort config directives Directive Description order Changes the order in which rules are applied. It is equivalent to the –o command line option. alertfile Used to set the name of the alert file. Alert file is created in log direc- tory see logdir directive. classification Builds classification for rules. See explanation of the classtype key- word used in rules. decode_arp Equivalent to –a command line option. It turns ON arp decoding. dump_chars_only Equivalent –C command line option. dump_payload Equivalent to –d command line option. It is used to dump the data part of the packet. decode_data_link Equivalent to –e command line option. Using this directive you can decode data link layer headers Ethernet header, for example. bpf_file Equivalent to –F command line option. set_gid Equivalent to –g command line option. Using this directive you can set the group ID under which Snort runs. For example, you can use “config set_gid: mygroup” daemon Equivalent to –D command line option. It invokes Snort as daemon instead of foreground process. reference_net Equivalent to –h command line option. It sets the home network address. interface Equivalent to –i command line option. It sets the interface for Snort. alert_with_interface_name Equivalent to –T command line option. This directive is used to append the interface name to the alert message. This is sometimes useful if you are monitoring multiple interfaces on the same sensor. logdir Equivalent to –l command line option. It sets the directory where Snort logs data. The default location of the log directory is varlog snort. The Snort Configuration File 115Parts
