Hi Community,

we have to sync our data over a WAN (Internet) connection and therefor we have to encrypt and compress the data during transmission but not the data itself on the target system. Is there an appropriate setting in viceversa?

Thx & Bye Tom

The connection which ViceVersa provides. ViceVersa should establish the connection, isn't it? Like rsnyc or Robocopy does. Or what exactly did you mean?

Hi , ViceVersa like Robocopy uses the connection that Windows provide. It does not implement its own protocol.

Okay, the reason why we don't want to use Robocopy was, that Robocopy uses the Windows SMB ports, including NetBIOS. If ViceVersa works it in the same way, we run into the same problems. Thank you for your attention...

Hi Tom,

ViceVersa use the Server Message Block (SMB) protocol to copy files between two hosts. SMB-based communications use the following ports:

137 (TCP/UDP) -- NetBIOS Name
138 (UDP) -- NetBIOS Datagram
139 (TCP) -- NetBIOS Session
445 (TCP) -- SMB over TCP

You can disable NetBIOS on a network interface by accessing the interface’s TCP/IP properties, clicking the Advanced button, then clicking the WINS tab, and finally clicking the "Disable NetBIOS over TCP/IP" radio button. With NetBIOS disabled, ViceVersa will automatically connect to the target system using TCP port 445. So you need to allow access through your firewall from the source system to the target system with port 445 as the destination.
