Logging In to Managed Resources Using a Web Browser for O&M

Constraints

• Only hosts using character protocols (SSH and Telnet) or image protocols (RDP and VNC) can be logged in using a web browser.
• The file transfer and management functions are unavailable for hosts using the Telnet protocol.
• Although using a web browser for O&M allows you to copy and paste a large number of characters without garbled characters, a maximum of 80,000 characters can be copied from the local to the remote, and a maximum of 1000,000 of bytes can be copied from the remote to the local.
• If you log in to a bastion host as a non-admin user and want to manage Windows host resources, deselect the admin console. To do so, go to the Operation > Host Operations page, click Web OPS Settings in the upper right corner, then deselect admin console.
• File management

  Files and folders cannot be edited in batches.

• File Transmission
  • By default, the system supports the upload of a single file with a maximum size of 100 GB. However, the size of a single file to be uploaded is limited by the Personal Netdisk space and browser type.
    

    If the disk space is insufficient, the upload will fail. In this case, you need to clear the disk or expand the disk capacity.

  • Folders cannot be downloaded.
  • For the hosts using the RDP protocol, only Netdisk can be select as the destination address.

Prerequisites

• You have the management permissions for the Host Operations module.
• You have obtained the access permissions for the resources.
• The network connection between the managed host and the system is normal, and the account username and password for logging in to the managed host are correct.
