3.1. Anti-virus Scanning Commands
The following commands to manage anti-virus scanning are available:
Command
|
Description
|
scan <path>
|
Purpose: Start checking the specified file or directory via the Dr.Web File Checker component.
Arguments:
<path>—path to the file or directory which is selected for scanning.
This argument may be omitted, if you use the --stdin or the --stdin0 option. To specify several files that satisfy a certain criterion, use the find utility (see the Usage Examples) and the --stdin or --stdin0 option.
Options:
-a [--Autonomous]—run a separate instance of Dr.Web Scanning Engine and Dr.Web File Checker to perform specified checks and terminate their operation after the scanning task is completed. Note that threats detected during stand-alone scanning are not added in the common threat list that is displayed using the threats command (see below).
--stdin—get the list of paths to scan from the standard input string (stdin). Paths in the list need to be separated by the next line character ('\n').
--stdin0—get the list of paths to scan from the standard input string (stdin). Paths in the list need to be separated by the zero character NUL ('\0').
|
When using --stdin and --stdin0 options, the paths in the list should not contain patterns or regular expressions for a search. Recommended usage of the --stdin and --stdin0 options is processing a path list (generated by an external utility, for example, find) in the scan command (see Usage Examples).

|
|
3.3. Configuration Management Commands
The following commands to manage configuration are available:
Command
|
Description
|
cfset
<section>.<parameter> <value>
|
Purpose: to change the active value of the specified parameter in the current configuration.
Note that an equals sign is not allowed.
Arguments:
•<section>—name of the configuration file’s section where the parameter resides. This argument is mandatory. •<parameter>—name of the parameter. The argument is mandatory. •<value>—new value that is to be assigned to the parameter. The argument is mandatory. The following format is always used to specify a parameter value: <section>.<parameter> <value>.
Note that if you want to indicate several parameter values, you need to repeat the call of the command cfset as many times as the number of parameter values you want to ass. In addition, to ass a new value to the list of the parameter values, you need to use an option -a (see below). You cannot use the command option <parameter> value1, value2, because the string value1, value2 will be considered a unified parameter value.
For description of the configuration file, refer to the section Appendix D. Configuration File, or to the documentation page displayed by man 5 drweb.ini.
Options:
-a [--Add]—do not substitute the current parameter value but add the specified value to the list (allowed only for parameters that can have several values, specified as a list). You should also use this option to when adding a new parameter group identified by a tag.
-e [--Erase]—do not substitute the current parameter value but remove the specified value from the list (allowed only for parameters that can have several values, specified as a list). You can also use this option to delete the whole group of parameters with a tag.
-r [--Reset]—reset the parameter value to the default. At that, <value> is not required in the command and is ignored if specified.
Options are not mandatory. If they are not specified, then the current parameter value (the entire list of values, if the parameter currently holds several values) are substituted with the specified value.
If you use the -r option for sections that contain individualized parameter settings for different connection points to the Dr.Web ClamD component or for sections that contain individualized parameter settings for different shared directories for the SpIDer Guard for SMB monitor, parameter value in the individualized settings section will be changed to the value of its “parent” parameter having the same name and located in the general settings section of this component.
If it is necessary to add a new connection point <point> for Dr.Web ClamD or a section containing parameters for a Sambashared directory with the <tag>, use the following command:
cfset ClamD.Endpoint.<point> -a, for example:
cfset ClamD.Endpoint.point1 -a
cfset SmbSpider.Share.<tag> -a, for example:
cfset SmbSpider.Share.BuhFiles -a
|
This command requires drweb-ctl to be started with root privileges. If necessary, use the su or sudo commands.
|
|
cfshow
[<section>][.<parameter>]
|
Purpose: to display parameter values in the current configuration. The parameters are output to the display as follows <section>.<parameter> = <value>. Sections and parameters of non-installed components are not displayed.
Arguments:
•<section>—name of the configuration file section parameters of which are to be displayed. The argument is optional. If not specified, parameters of all configuration file sections are displayed. •<parameter>—name of the displayed parameter. If not specified, all parameters of the section are displayed. Otherwise, only this parameter is displayed. If a parameter is specified without the section name, all parameters with this name from all of the configuration file sections are displayed. Options:
--Uncut—display all configuration parameters (not only those used with the currently installed set of components). If the option is not specified, only parameters used for configuration of the installed components are displayed.
--Changed—output only those parameters which have values different from the default ones.
--Ini—display parameter values in the INI file format: at first, the section name is specified in square brackets, then the section parameters listed as <parameter> = <value> pairs (one pair per line).
--Value—output only value of the specified parameter (the <parameter> argument is mandatory in this case).
|
reload
|
Purpose: to send the SIGHUP signal to the Dr.Web ConfigD configuration daemon.
On receiving this signal, the Dr.Web ConfigD configuration daemon rereads the configuration and sends the required changes of it to Dr.Web for UNIX File Servers components. Then the configuration daemon reopens the program log, restarts the components that use virus databases (including the anti-virus engine), and attempts to restart those components which were terminated abnormally.
Arguments: None.
Options: None

Note that objects are deleted from quarantine permanently—this action is irreversible.
--Cure <object>—try to cure the specified object in the quarantine.
Note that even if the object is successfully cured, it will remain in quarantine. To restore the cured object from quarantine, use the --Restore command.
--Restore <object>—restore the specified object from the quarantine to its original location.
Note that this command may require drweb-ctl to be started with superuser privileges. You can restore the file from quarantine even if it is infected.
--TargetPath <path>—restore an object from the quarantine to the specified location: either as a file with the name specified here (if the <path> is a path to a file), or just to the specified directory (if the <path> is a path to a directory). Can be used only in combination with the --Restore command.
As an <object> specify the object identifier in quarantine. To apply the command to all quarantined objects, specify All instead of <object>. For example,
$ drweb-ctl quarantine --Restore All
|
restores all quarantined objects.
Note that for the --Restore All variant the additional option --TargetPath, if specified, must set a path to a directory, not a path to a file.
|
nss_threats
[<action> <object>]
|
Purpose: Apply the specified action to threats detected on NSS volumes; threats are selected by their identifiers. Type of the action is specified by the command’s option.
If the action is not specified, displays information on detected but not neutralized threats. The displayed information is essentially the same as the one that is displayed by calling the threats command (see above); but the scope of the information may be extended or modified based on the peculiarities of NSS storage.
|
To use this command, it is necessary to have SpIDer Guard for NSS installed and started.
|
Arguments: None.
Options:
-f [--Follow]—wait for new messages about new threats and display the messages once they are received (CTRL+C interrupts the waiting).
--Cure <threat list>—attempt to cure the listed threats (list threat identifiers separating them with commas).
--Quarantine <threat list>—move the listed threats to NSS quarantine (specify threat identifiers as a comma-separated list).
--Delete <threat list>—delete the listed threats (list threat identifiers separating them with commas).
--Ignore <threat list>—ignore the listed threats (list threat identifiers separating them with commas).
If it is required to apply the command to all the threats detected on NSS volumes specify All instead of a <threat list>. For example:
$ drweb-ctl nss_threats --Quarantine All
|
moves all detected malicious objects to NSS quarantine.
|
nss_quarantine
[<action> <object>]
|
Purpose: to apply an action to the specified object located in quarantine on NSS volumes.
If not specified, the following information is output: object identifier in NSS quarantine and brief information on original files. The displayed information is essentially the same as the one that is displayed by calling the quarantine command (see above); but the scope of the information may be extended or modified based on the peculiarities of NSS storage.
|
To use this command, it is necessary to have SpIDer Guard for NSS installed and started.
|
Arguments: None.
Options:
--Delete <object>—delete the specified object from quarantine NSS.
Note that objects are deleted from quarantine permanently—this action is irreversible.
--Cure <object>—try to cure the specified object in the quarantine NSS.
Note that even if the object is successfully cured, it will remain in quarantine. To restore the cured object from quarantine, use the --Restore command.
--Rescan <object>—rescan the specified object in the NSS quarantine.
Note that even if the rescanning will determine that the object is clean (not infected), it will stay in quarantine. To restore the object from quarantine, use the --Restore option.
--Restore <object>—restore the specified object from the NSS quarantine.
Note that this command may require drweb-ctl to be started with superuser privileges. You can restore the file from quarantine even if it is infected.
--TargetPath <path>—restore an object from the quarantine to the specified location: either as a file with the name specified here (if the <path> is a path to a file), or just to the specified directory (if the <path> is a path to a directory).
Can be used only in combination with the --Restore command.
As an <object> specify the object identifier in NSS quarantine. To apply the command to all quarantined objects, specify all as an <object>. For example, the following command:
$ drweb-ctl quarantine --Restore All
|
restores all quarantined objects.
Note that for the --Restore All variant the additional option --TargetPath, if specified, must set a path to a directory, not a path to a file.
|
|
If the Quarantine action is specified for some threat type in the settings of SpIDer Guard for NSS, the object containing a threat of this type will be placed to quarantine again on attempt to restore this object from quarantine to an NSS volume by the nss_quarantine command. For example, the following default settings:
NSS.OnKnownVirus = Cure
NSS.OnIncurable = Quarantine
move all incurable objects to quarantine. This is why, when any incurable object is restored from quarantine to an NSS volume by the nss_quarantine command, this object is automatically returned to quarantine.

3.5. Information Commands
The following information commands are available:
Command
|
Description
|
appinfo
|
Purpose: Output information on active Dr.Web for UNIX File Servers components.
The following information is displayed about each component that is currently running:
•Internally-used name •Process identifier GNU/Linux (PID) •State (running, stopped etc.) •Error code, if the work of the component has been terminated because of an error •Additional information (optionally). For the configuration daemon Dr.Web ConfigD the following is displayed as additional information:
•The list of installed components—Installed •The list of components which must be launched by the configuration daemon—Should run. Arguments: None.
Options:
-f [--Follow]—wait for new messages on component status change and output them once such a message is received (interrupt waiting by pressing CTRL+C).
|
baseinfo
|
Purpose: Display the information on the current version of the Virus-Finding Engine and status of virus databases.
The following information is displayed:
•Version of the anti-virus engine •Date and time when the virus databases that are currently used were issued. •The number of available virus records (in the virus databases) •The time of the last successful update of the virus databases and of the anti-virus engine •The time of the next scheduled automatic update Arguments: None.
