Prerequisites for the agentless configuration

Prerequisites for using the agentless feature in Linux

Have the following information with you:
- Host user name
- Host password or SSH key
CloudPoint requires these details to gain access to the host and perform requested operations.
On hosts where you wish to configure this feature, grant password-less sudo access to the host user account that you provide to CloudPoint.

Granting password-less sudo access to host user account

CloudPoint requires a host user account to connect and perform operations on the host. You must grant password-less sudo access to the user account that you provide to CloudPoint. This is required for all the hosts where you wish to configure the agentless feature.

Note:

The following steps are provided as a general guideline. Refer to the operating system or the distribution-specific documentation for detailed instructions on how to grant password-less sudo access to a user account.

Perform the following steps on a host where you want to configure the agentless feature
Verify that the host user name that you provide to CloudPoint is part of the wheel group.
Log on as a root user and run the following command:
# usermod -aG wheel hostuserID
Here, hostuserID is the host user name that you provide to CloudPoint.
Log out and log in again for the changes to take effect.
Edit the /etc/sudoers file using the visudo command:
# sudo visudo
Add the following entry to the /etc/sudoers file:
hostuserID ALL=(ALL) NOPASSWD: ALL
In the /etc/sudoers file, edit the entries for the wheel group as follows:
- Comment out (add a # character at the start of the line) the following line entry:
  # %wheel ALL=(ALL) ALL
- Uncomment (remove the # character at the start of the line) the following line entry:
  %wheel ALL=(ALL) NOPASSWD: ALL
The changes should appear as follows:
```
## Allows people in group wheel to run all commands
# %wheel ALL=(ALL) ALL

## Same thing without a password
%wheel ALL=(ALL) NOPASSWD: ALL
```
Save the changes to the /etc/sudoers file.
Log out and log on to the host again using the user account that you provide to CloudPoint.
Run the following command to confirm that the changes are in effect:
# sudo su
If you do not see any prompt requesting for a password, then the user account has been granted password-less sudo access.
You can now proceed to configure the CloudPoint agentless feature.

Prerequisites for using the agentless feature in Windows

The user account used to connect to remote instance should be able to:
- Access remote admin share (ADMIN$). Enabled by default.
- Access to root\cimv2
Configure the following ports:
- Modify the security group to allow inbound traffic on the ports 135, 445 and dynamic port or fixed port for WMI .
- Enable inbound rules in the firewall for the ports 135, 445 and the dynamic or fixed WMI-IN ports on Windows hosts.
  Note:
  The dynamic range for the ports is 49152-65535.
- You can use fixed or dynamic WMI-IN ports. If you want to configure a fixed WMI-IN port, see https://docs.microsoft.com/en-us/windows/win32/wmisdk/setting-up-a-fixed-port-for-wmi

Disable User Account Control for the users groups accessing the agentless feature.
For protecting SQL applications, the user account used for connecting to the cloud host, must have the required admin privileges to access the SQL server.
