Alt-F provides a free alternative firmware for the DLINK DNS-320/320L/321/323/325/327L.

Alt-F has Samba and NFS; supports ext2/3/4, VFAT, NTFS and ISO9660 filesystems; RAID 0, 1, 5 (with external USB disk) and JBOD; supports 2/3/4TB disks; rsync, ftp, sftp, ftps, ssh, lpd, DNS and DHCP servers, DDNS, fan and leds control, clean power up and down... and more.

Alt-F also has a set of comprehensive administering web pages, you don't need to use the command line to configure it.

Besides the built-in software, Alt-F also supports additional packages on disk, including ffp and Entware-ng packages, that you can install, update and uninstall using the administering web pages

Alt-F is being developed and tested on a DNS-323-rev-A1/B1, a DNS325-rev-A1, a DNS-320L-rev-A1 and on a DNS-327L-rev-A1 hardware boards. Other models and boards are said to work.

  • Thank you for your work, it's an excellent firmware (DLNA, RSYNC...). It's working very well in version 1.0 on me DNS-323 REV B1

  • I'm a recent Alt-F adopter, and I must say it is a suitably impressive body of work. It is so refreshing to be rid of that lethargically slow D-Link eye candy, and be able to SSH into a proper Linux environment on my NAS boxes. I've successfully installed Alt-F-0.1RC6 on two DNS-320L A3 boxes, each with two 4TB drives in an ext4 raid0 configuration. I was in the process of clobbering both boxes to reconfigure as raid0 using D-Link's firmware, and decided to try the latest Alt-F firmware release instead. My initial configuration retained the hard drive configuration as brought over from D-Link's setup. To be honest, I found that unsatisfactory and reformatted the drives using the Alt-F HDD utilities, which resulted in a vastly cleaner and more familiar Linux file system and environment. I'm running FTP/SFTP, SSH, and Samba services. I configured and tested NFS, but have deactivated it to keep my active NAS services to a bare minimum. I am finding Alt-F to be lean, straight forward and very fast, particularly considering the scarce hardware resources these D-Link boxes offer. The Alt-F administrative web pages are extensive, highly functional, and get the job done with a minimum of fuss and effort. All in all, this is an incredibly well thought out, and rock solid firmware and headless Linux server environment running Linux kernel 4.4.45. It offers a robust package management environment that contains many software choices to satisfy any techie or NAS enthusiast. Yes, it greatly helps to have some experience in building and maintaining Linux servers, but disregard the minimal one star ratings from people who choose to blame others for their own shortcomings. Read and understand everything before you attempt installing ANY firmware, regardless of who made it. Back up your terabytes of "very precious data" before uploading it on any NAS device. Have a backup strategy to begin with. I've got two on-site backup copies of my entire NAS, and I'm building the 2nd NAS box specifically to ship to another family member across the country as an off-site duplicate copy that I will administer from the west coast. This ambitious and robust software effort turns a D-Link multimedia toy into a serious Linux server capable of handling large volumes of data, decent throughput and a variety of web enabled services. Very well done!

  • DNS-323 HW Rev.C. Works just fine

  • Freaking awesome that you invest time and effort into these devices, keep it up

  • New life for my Dlink DNS 325. Not only a NAS with limited functionalities, but expanded also with unexpected server (MySQL ;)). Now is what I wanted to buy years ago. Also appreciated a real good spped increase respect to the original software. Not racomended to newbies due to the fact that some options are not comprhenive to a normal user.
