|
Description: turn on the shell tracing (log detailed information on file scanning performed by Dr.Web Virus-Finding Engine).
|
|
|
--LogLevel
|
<logging level>
|
Description: level of detail at which operation of Dr.Web Scanning Engine is logged. Allowed values:
•DEBUG — the most verbose logging level. All messages and debug information are registered. •INFO — all messages are registered. •NOTICE — all error messages, warnings, and notifications are registered. •WARNING — all error messages and warnings are registered. •ERROR — only error messages are registered. |

--Log
|
<destination>

Description: method for logging module messages. Allowed values:
•Stderr[:ShowTimestamp] — messages are output to a standard error stream stderr.
Additional option ShowTimestamp prescribes to add a time stamp to every message. •Syslog[:<facility>] — messages are transmitted to the system logging servicesyslog.
Additional option <facility> is used to specify a level at which syslog registers messages. The following values are possible: oDAEMON — messages of daemons oUSER — messages of user processes oMAIL — messages of mail programs oLOCAL0 — messages of local processes 0 ...
oLOCAL7 — messages of local processes 7. •<path> — path to the file where all messages are registered. Examples:
--Log /var/opt/drweb.com/log/se.log
--Log Stderr:ShowTimestamp
--Log Syslog:DAEMON
|
Example:
$ /opt/drweb.com/bin/drweb-se -c /etc/opt/drweb.com/drweb.ini --MaxForks=5
This command starts an instance of Dr.Web Scanning Engine, instructs it to use the /etc/opt/drweb.com/drweb.ini configuration file, and sets the limit to start no more than 5 child scanning processes.
Notes about startup
When necessary, any number of scanning engine Dr.Web Scanning Engine instances can be started. The instances provide client applications (not only Dr.Web for UNIX File Servers components) with the scanning service. If the parameter Dr.Web for UNIX File Servers SeFixedSocketPath (in the section [ScanEngine]), is specified, one the scanning engine instances will be always running (started by configuration daemon Dr.Web ConfigD). The instances of the scanning engine started directly from the command line, will operate in standalone mode without establishing connection to the configuration daemon, even if it is running.
To scan files at request, use the command-line command-line tool for the solution management from the command line Dr.Web Ctl (it is run by drweb-ctl command).
