Configuration Parameters

Top  Previous  Next

The component uses configuration parameters which are specified in the [ScanEngine] section of the integrated configuration file of Dr.Web for UNIX Mail Servers.

This section stores the following parameters:

LogLevel

{logging level}

Logging level of the component.

If the parameter value is not specified, the DefaultLogLevel parameter value from the [Root] section is used.

Default value: Notice

Log

{log type}

Logging method

ExePath

{path to file}

Path to the executable file of the component.

Default value: <opt_dir>/bin/drweb-se

For Linux, Solaris: /opt/drweb.com/bin/drweb-se

For FreeBSD: /usr/local/libexec/drweb.com/bin/drweb-se

FixedSocketPath

{path to file}

Path to the UNIX socket of the fixed Dr.Web Scanning Engine scanning engine instance.

If this parameter is specified, the Dr.Web ConfigD configuration daemon checks that there is always a running component copy of scanning engine that is available to the clients via this socket.

Default value: (not specified)

IdleTimeLimit

{time interval}

Maximum time that the component can remain idle. If the specified value is exceeded, the component shuts down.

Minimum value—10s.

If the FixedSocketPath parameter is set, this setting is ignored (the component does not finish its operation after the time interval expires).

Default value: 30s

MaxForks

{integer}

Maximum allowed number of child processes run by Dr.Web Scanning Engine, which can be run simultaneously.

Default value: Automatically determined as twice the number of available CPU cores; or 4, if the resulting number is less than 4.

MaxForksPerFile

{integer}

Maximum allowed number of Dr.Web Scanning Engine child scanning processes, which can be used simultaneously for scanning container files (such as archive).

Cannot be less than 1 and greater than the MaxForks parameter value.

Default value: Automatically determined as MaxForks/2.

BufferedIo

{On | Off}

Use buffered input/output (I/O) when checking files.

Using buffered I/O in the FreeBSD and Linux OSes can increase scanning speed of the files on slow disks.

Default value: Off

WatchdogInterval

{time interval}

Rate at which Dr.Web Scanning Engine checks whether child processes are operable in order to detect processes that stopped responding (“watchdog”).

Default value: 1.5s
