The DNS queries and responses captured on an IB-4030 appliance does do not contain cached query information.


    • Select Capture queries/responses for all domains to capture queries and responses to all domains and zones.
    • Select Limit capture to these domains to capture DNS queries and responses to domains and zones one at a time.
    • Specify domains for DNS capture operations in the Domain table by clicking the Add icon, and choosing Add Domain or Bulk Add Domains from the menu.
    • Select Exclude The Following Domains to exclude individual domains and their subdomains from DNS query and response capturing. For more information, see Excluding Domains From Query and Response Capture.
    • To define the destination for capture files, do the following:
      • Retain captured queries/replies on the local disk: Select this check box to save the DNS queries on the appliance. In addition to the local disk, you can select to export the DNS queries to the remote server by selecting SCP in the Export to drop-down list.
      • Export to: From the drop-down list, select SCP to back up the DNS queries on the remote server and None to save queries only on the appliance. To save the captured DNS queries on both the appliance and the remote server, select the Retain captured queries/replies on the local disk check box and SCP from the Export to drop-down list.

When you configure an SCP server and enable the MGMT port, the NIOS appliance uses SSH for data transfer. It uses the same authentication and provides the same security as SSH. SCP uses the LAN1 port to communicate with the external servers.

    • TCP port: If you have configured a Data Connector as an SCP source into which to send the DNS log files, specify the port number for the Data Connector. You can specify a range between 1 to 65535. The default port number is 22.
    • When you select FTP or SCP from the Export to drop-down list, complete the following:
      • In the Directory Path field, enter the directory to which the capture file will be saved on the server. Infoblox recommends that you use the ~ symbol for the remote server.
      • In the Server Address field, enter the IP address of the remote server to which the capture files will be saved.
      • Enter the file server account Username and Password values.
    • Limit query data collected per file to minutes or 100MB (whichever comes first): This option limits the collection of query data per capture file. A capture file for logging DNS queries and responses is rolled over based on the configured time limit or when the file reaches 100 MB in size, whichever is sooner. The default time limit is 10 minutes. You can enter a value from 1 to 10.
