Dualog® Drive - System Requirements

FIREWALL CONFIGURATION

Client registration and client-server communication require an internet connection. A functioning DNS server configuration is also required to ensure a smooth operation. If DNS traffic is blocked, a custom DNS entry, to resolve "apps.dualog.com" as described below, is required to complete the installation and registration of Dualog Drive. 

The following URL’s or IP addresses must be accessible:

Direction Source IP Source Port Remote IP Remote Port

*Mobile to

remote / fixed

All All

93.188.232.76

apps.dualog.com

443

4443** All

All

 

* “Mobile” = Vessel/office installation
* “Remote / fixed” = Shore host
** Port 4443 is used by Sync when client OS is Windows 8/Server 2012 or older. For newer OS it is not required to open this port. Also, if only using Move it is not required to open this port.

In addition, additional IP ports must be open/blocked for carrier detection.

 

FILE SHARE AS SOURCE OR DESTINATION FOR DRIVE TASKS

Dualog Drive uses SMB to access file shares/file servers. Supported SMB versions are 2.02, 2.1, and 3.0.

Samba 2.1 is required. Do make sure that it is enabled. For more information, please check Microsoft Documentation.

As a minimum, port 445 (TCP) must be open in the firewall to allow traffic between the Drive computer and the fileserver. Depending on the SMB version and Operating systems, ports 137 & 138 (UDP) and 139 (TCP) might be required to open as well.

Be aware that opening 137 and 138 is a security risk. We highly recommend upgrading to a newer Operating system.

 

SUPPORTED OPERATING SYSTEMS

The following operating systems are supported:

  • Windows 7 SP 1 (*)
  • Windows 8.1 (*)
  • Windows 10 (version 1607) or later
  • Windows Server 2008 R2 SP1 (*)
  • Windows Server 2012 SP1 (*)
  • Windows Server 2012 R2 (*)
  • Windows Server 2016 or later

 (*) Microsoft Visual C++ 2015 (x86) is required for Windows 8.1/Server 2012 R2 and older. Do make sure it is installed. For more information, please check Microsoft documentation.

HARDWARE REQUIREMENTS

Hardware requirements like CPU, memory, and disk space are very dependent on the type of tasks and number of tasks. As an example, a computer only handling small files to be replicated to shore will not have the same requirements as a computer handling multiple tasks where large amounts of data are received from hundreds of clients.


To reduce bandwidth usage, the protocol for Sync tasks stores data chunks on disk. This data storage will grow, so prepare the disk space to be able to handle approx double the expected data volume to be synchronized.


Required disk space must be calculated based on knowledge of expected data volume.

Recommended disk space: 1TB
