Download Firmware Synology Disk Station Manager 5.1 build 5021

Synology has released a new version of Disk Station Manager 5.1. Synology DSM is the management software that runs on several of the company’s NAS products. The Disk, Cube and Rack Stations offer more than just extra storage space. For example, backups of all clients on the network can be made and files can be downloaded via http, ftp, bittorrent, usenet and emule, so that, for example, energy-hungry PCs can switch off at night while the download just comes in. In addition, audio and video files can be streamed over the network via the built-in iTunes server, a dynamic website can be hosted using PHP and MySQL and the device can act as a print server.

In order to install version 5.1, at least version 5.0 must be present. This update can be installed on nas models ending in 10 or higher, which is an improvement, because the first release of DSM 5.1 still required at least one model ending in 11. In version 5.1 we find several improvements related to up to security. For example, there is a security advisor that warns you about unsafe settings and the Application Armor kernel security module is now enabled by default. In version 5.1 build 5021 we find several bug fixes and some security vulnerabilities have been fixed.
