G1. Dr.Web Server Configuration File

The drwcsd.conf Dr.Web Server configuration file resides by default in the etc subfolder of the Dr.Web Server installation folder. If Dr.Web Server is run with a command line parameter, a non-standard location and name of the configuration file can be set (for more read Appendix H3. Dr.Web Server).

To manage Dr.Web Server configuration file manually, do the following:

1.Stop Dr.Web Server (see Administrator Manual, p. Start and Stop Dr.Web Server).

2.Disable self-protection (in case of installed Agent with the active self-protection—in the Agent context menu).

3.Manage the Dr.Web Server configuration file.

4.Start Dr.Web Server (see Administrator Manual, p. Start and Stop Dr.Web Server).

Dr.Web Server Configuration File Format

Dr.Web Server configuration file is in XML format.

Description of Dr.Web Server configuration file parameters:

<version value="" />

Current version of the configuration file.

<name value="" />

Name of Dr.Web Server or a cluster of Dr.Web Servers, which is used when it is searched by Agent, Agent installers and Control Center. Leave the value blank ("" is used by default), to use the name of a computer where Dr.Web Server software is installed.

<id value="" />

The Dr.Web Server unique identifier. In the previous versions was placed in the Dr.Web Server license key. Starting from version 10, it is stored in the Dr.Web Server configuration file.

<passwd-salt value="" />

A cryptographic salt. A string of random data that is added to administrator password. The combined value is hashed by a hash function and stored as a single hash in the database to protect the password from brute force cracking. The salt is generated by default after installation or upgrade of Dr.Web Server from previous versions. An empty value prescribes not to use the password encryption (not recommended).

info

Viewing or changing the administrator password using the provided database management utility (drwidbsh3) is impossible when the salt is present.

warning

When using a Dr.Web Server cluster, make sure to manually set the same salt value on every Dr.Web Server included in the cluster.

Child element

Attribute

Description

Default

port

<port value="" />

value

The Dr.Web Server's network interface port number that is used by transport multicast protocol to transmit the updates. This port is used by all multicast groups.

For multicast updates, you must specify any unused port that will be different from the one specified in the Dr.Web Server's transport protocol settings.

2197

ttl

<ttl value="" />

value

Time-to-live of transferred UDP-datagram. This value will be used by all multicast groups.

8

group

<group address="" />

address

IP address of a multicast group the stations will receive multicast updates from.

233.192.86.0 for IPv4

FF0E::176 for IPv6

on

<on interface="" ttl="" />

interface

IP address of Dr.Web Server network interface that transport multicast protocol is bound to for updates transmission.

ttl

Time-to-live of a UDP-datagram transferred through specified network interface. Has a higher priority than the general <ttl value="" /> child element.

8

transfer

<transfer datagram-size="" assembly-timeout="" updates-interval="" chunks-interval="" resend-interval="" silence-interval="" accumulate-interval="" announce-send-times="" />

datagram-size

UDP datagram size (bytes)—size of UDP datagrams in bytes.

Allowed range is 512–8192. To avoid fragmentation, it is recommended that you set a value less than MTU (Maximum Transmission Unit) of the network.

1400

assembly-timeout

File transmission time (ms.)—during the specified time, single update file is transmitted, after that Dr.Web Server starts sending the next file.

All files, which failed to transmit as a part of multicast protocol update, will be transmitted as a part of standard update process over the TCP protocol.

180000

updates-interval

Duration of multicast updates (ms.)—duration of update process via multicast protocol.

All files that failed to transmit at the stage of updating via multicast protocol will be transmitted as a part of the standard update via TCP protocol.

600000

chunks-interval

Package transmission interval (ms.)—interval of package transmission to a multicast group.

The low interval value may cause significant losses during package transfer and overload the network. It is not recommended to change this parameter.

14

resend-interval

Interval between requests for retransmission (ms.)—at this interval Agents send out requests for retransmission of lost packages.

Dr.Web Server accumulates these requests and sends out any lost blocks afterwards.

1000

silence-interval

“Silence” interval on the line (ms.)—whenever a file transmission is over before the allowed time has expired and if during a specified “silence” interval no requests for retransmission of lost packages are received from Agents, Dr.Web Server assumes that all Agents successfully received update files and initiates transmission of the next file.

10000

accumulate-interval

Retransmission request accumulation interval (ms.)—during the specified interval, Dr.Web Server accumulates requests from Agents for retransmission of lost packages.

Agents request for lost packages. Dr.Web Server accumulates these requests throughout the specified time and sends out any lost blocks afterwards.

2000

announce-send-times

Number of file transmission announcements—A number of times Dr.Web Server announces a file transmission to a multicast group before the update transmission starts.

The announcement means a UDP-datagram with file metadata, which is sent to a multicast group. Increasing the number of announcements can potentially improve transmission reliability, but at the same time can lead to decreased amount of data that can be transmitted over the multicast protocol for the time allowed.

3
