Ghost multicast Server to client negotiation

I need a solution


we are using ghost server to multi clients using multicast.

Just a question on bandwidth and communication.

When the image is being transferred my understanding is that the communication is via udp.

Does anyone know how the client server communication for setup works?

Also what determines the max transfer speed? I know this is the slowest client but how does this

client communicate the speed it is happy with to the server, is this again tcp?

Is there a tcp “management” stream between client and server checking for variations in speed capabilities?

Any help or if anyone knows where to find it much appreciated.

Download, Send, Rename or Delete a Folder

Download Folder

Right-click the folder and select Download from the drop down menu.

Download Folder Limitations

  • If any file within the folder has a file path longer than 180 characters, you will be unable to download the entire folder. You will need to shorten that file path or navigate further into the folder to download individual files or subfolders.
  • Download speed is determined by your connection speed and the size of the folder being downloaded.

Rename a Folder

You can rename folders and subfolders as needed. This action requires the Admin and Delete permissions on the folder. The original creator or owner of this folder will automatically have the Admin permissions required to rename it.

To rename a folder:

  1. Right-click the folder and select Rename.
  1. Type in the new name in the text box.
  1. Click Save.

Share a Folder

After you have uploaded files to a folder, right-click the folder and select Share. You can share by utilizing Email with ShareFile or Get a Link to send from your email app.

Delete a Folder

To delete a folder, right-click the folder and choose the Delete option.

The Delete Folder option will only be available to the owner of the folder or a member of the Super User Group. For a user without these permissions, the Delete Folder option will simply be absent from the drop-down menu.


Workspace Web: Managing Folder Permissions

  • Email users when files are downloaded

With download alerts, users are notified with an email that files were downloaded from the folder. A user must be granted admin permission on the folder to be granted download alerts, as it will allow them to identify other users on the folder when they download documents.

  • Email users when files are uploaded

With upload alerts, users are notified with an email that files were uploaded to the folder. In order to be granted this permission, the user does have to also be granted the download permission. Users with download permission will also be able to grant themselves this permission through a checkbox on the folder.
