1. Select the Administration item in the main menu of the Control Center.
2. Select Web server Configuration in the control menu. A window with Web server configuration will be opened.
Values of fields, marked by the * sign, must be obligatory specified.
3. On the toolbar, the following buttons to manage the section settings are available:
Restart Dr.Web Server—restart the Server to apply changes that have been specified in this section. The button become enabled after you specified the changes in the section settings ans click Save.
Restore configuration from the backup—drop-down list with the backup of all section set-tings, which you can restore after making changes. The button become enabled after you specified the changes in the section settings ans click Save.
Reset all parameters to initial values—restore the values that all parameters in this section had before current editing (last saved values).
Reset all parameters to default values—restore default values of all parameters in this sec-tion.
4. To apply the changes specified in the section settings, click Save, after this the Server must be re-booted. To do this, click Restart Dr.Web Server on the toolbar of this section.
7.5.1. General
On the General tab, specify the following Web server settings:
uDr.Web Server address—IP address or DNS name of Dr.Web Server.
Parameter is specified in the following format:
<Server IP address or DNS name>[:<port>]
If the Server address is not specified, computer name returned by the operating system or the Server network address: DNS name, if available, otherwise—IP address are used.
If the port number is not specified, the port from a request is used (e.g., for requests to the Server from the Control Center or via the Web API). Particularly, for the requests from the Control Center it is the port specified in the address line for connection of the Control Center to the Server.
The value is stored in the <server-name /> parameter of the webmin.conf configuration file.
This parameter value is also used to generate the link for downloading the Agent installation file for an anti-virus network stations.
uParallel requests number—number of parallel requests processed by the Web server. This para-meter affects server performance. It is not recommended to change this parapara-meter without need.
uIO threads number—number of threads serving data transmitted in network. This parameter af-fects Server performance. It is not recommended to change this parameter without need.
uTimeout (sec)—HTTP session timeout. For persistent connections, Server releases the connection, if there are no requests received from a client during specific time slot.
uMinimal send rate (BPS)—minimal acceptable data send rate. If outgoing network speed is lower than this value, connection will be rejected. Specify 0 to ignore this limit.
uMinimal receive rate (BPS)—minimal acceptable data receive rate. If incoming network speed is lower than this value, connection will be rejected. Specify 0 to ignore this limit.
uSend buffer size (KB)—size of buffers used when sending data. This parameter affects server per-formance. It is not recommended to change this parameter without need.
uReceive buffer size (KB)—size of buffers used when receiving data. This parameter affects server performance. It is not recommended to change this parameter without need.
uMax request length (KB)—Maximum allowed size of HTTP request.
uUse compression—set the flag to use traffic compression for data transmission over a communica-tion channel with the Web server via HTTP/HTTPS.
· If the flag is set, the Compression level drop-down list become available. In this list, you can select the data compression level from 1 to 9, where the 1 is minimal level and the 9 is maximal compression level.
uReplace IP addresses—set the flag to replace IP address with DNS names of computers in the Server log file.
uKeep-alive SSL connection—set the flag to use keep-alive SSL connection. Older browsers may not work properly with regular SSL connections. Disable this parameter, if you have problems with SSL protocol.
uSSL certificate—path to SSL certificate file. The drop-down list contains available certificates from the Server folder.
uSSL private key—path to SSL private key file. The drop-down list contains available private keys from the Server folder.
7.5.2. Additional
On the Additional tab, specify the following Web server settings:
uSet the Show script errors flag to show script errors in browser. This parameter is used by tech-nical support and developers. It is not recommended to change this parameter without need.
uSet the Trace scripts flag to enable scripts tracing. This parameter is used by technical support and developers. It is not recommended to change this parameter without need.
uSet the Abort scripts flag to allow aborting of scripts execution. This parameter is used by technical support and developers. It is not recommended to change this parameter without need.
7.5.3. Transport
On the Transport tab, you can configure network addresses to listen for accepting incoming connec-tions by the Web server, e.g., for connection of the Control Center or executing requests via the Web API:
uIn the Addresses to listen on HTTP section, you can configure the list of interfaces to listen for ac-cepting connections via the HTTP protocol:
In the Address and Port fields, specify correspondingly the IP address and the port number of the network interface from which HTTP connections can be accepted.
By default, the following parameters are set to "listen" by the Web server:
· Address: 0.0.0.0—use "all network interfaces" for this computer, on which the Web server is installed.
· Port: 9080—use the standard 9080 port for the HTTP protocol.
uIn the Addresses to listen on HTTPS section, you can configure the list of interfaces to listen for accepting connections via the HTTPS protocol:
In the Address and Port fields, specify correspondingly the IP address and the port number of the network interface from which HTTPS connections can be accepted.
By default, the following parameters are set to "listen" by the Web server:
· Address: 0.0.0.0—use "all network interfaces" for this computer, on which the Web server is installed.
· Port: 9081—use the standard 9081 port for the HTTPS protocol.
To add a new address field, click in the corresponding section. To delete a field, click next to the deleting field.
7.5.4. Security
On the Security tab, you can configure restrictions for network addresses from which the Web server receives HTTP and HTTPS requests.
