Discover agentless servers

You can use the SA Client to install agents on a large number of servers. To discover agentless servers, you specify a location to scan for servers and a set of IP addresses. SA performs a network scan to locate and identify servers. Instead of entering addresses into the input field, you can import a file containing of IP addresses or IP address ranges. When the scan is complete, SA displays a list of scanned servers.

SA determines the status of each server, its IP address, its host name, detected operating system, and open ports used to connect to the server.

To scan for agentless servers and install agents on them using the SA Client:

  1. From the SA Client navigation pane, select the Devices tab and then select Servers > SA Agent Installation.
  2. Select a realm to scan for servers from the “Scan in” drop-down list. For more information about realms, see the SA 10.51 Administer section.

  3. In the Targets field, click the ... button to select a realm and enter as many IPv4 or IPv6 addresses as you want to scan.
  4. Click Scan to scan for servers. When the scan is complete, the list of servers is shown. For each server, SA determines the status of the server, its IP address, its host name, the detected operating system and open ports that can be used to connect to the server. You can click on any of the column headings to sort the server list by that column.

    If you have a firewall enabled, SA may not be able to accurately detect a server’s actual installed operating system. Some firewalls can interfere with the methods SA uses to detect the operating system. SA must be able to access at minimum one open port and one closed port to gather the information needed to determine the operating system. If you find that SA has not identified any operating system or has misidentified the operating system, you may need to configure your firewall to allow network packets from the SA core.

    The following figure shows the results of a network scan for servers. The actual operating system of the server can be only determined if SA is able to successfully log into the server.

5. Install the SA agent on these servers, as described in Install the SA Agent.
