How Do I Upload or Download Files When I Log In to Managed Hosts Using a Web Browser?

During web-based O&M, you can upload or download files in File Transfer tab. This feature enables file transfer between a local computer and managed host and between different managed hosts. The CBH system records the entire file transfer process in detail, making it easier to audit file upload and download operations.

Netdisk is a personal net disk in a CBH system, which is preset for each system user. A user can temporarily store files on it for file transfer between managed hosts. The file content in the personal net disk is visible only to users who creates the file.

Netdisk is directly associated with each system user. If a user is deleted, the files on the personal net disk are cleared and the personal net disk space is released.

Constraints

  • Currently, only SSH and RDP hosts support file upload and download through web-based O&M.
  • During web-based O&M, users cannot upload files to or download files from managed hosts by running the rz or sz command but only through File transfer.

    For Linux hosts, users can transfer files by running commands on the SSH client. For example, users can run the rz or sz command on the SSH client to upload or download files. However, the CBH system cannot record such file upload and download data, and the purpose of security audit cannot be met.

  • Web-based O&M allows you to download one or more files but not folders.
  • Resumable download is not supported. Do not stop or pause the file upload or download process.
  • The size of the file to be transferred cannot exceed 1 GB. It is recommended that large files be split and transferred in several batches.

Prerequisites

  • You have the permissions to upload and download host resource files.
  • You have the host O&M permissions and can log in to the managed host using a web browser.

  2. Choose Operation > Host Operation and locate the target Windows host.
  3. Click Login to open the Windows host O&M session.
  4. Click File Transfer to list of host files on the personal net disk.
