    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!

    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.

    Большое спасибо! Это решение намного лучше заводской версии прошивки! Было неплохо добавить возможность изменять тему.

    Gave new life to my DNS-325-A2. The stock firmware from D-Link was not that bad but some add-ons were poor, for example aMule add-on. With Alt-F everything works out-of-the-box, my files were preserved and there are a number of add-ons that look interesting. I installed the aMule add-on and it appears to work well, coupled with its corresponding front-end "aMuleGui". The ability to define some shortcuts is really useful for saving time for starting/stopping some services when needed. Keep up the excellent work. Thank you Aldo

    Thank you so much for this... allowed me to expand use of my DNS321 to larger drive sizes and has given it the ability to do self-backups. I just wish I could get the miniDLNA to work...

    Can't figure out this thing at all. About as user-friendly as a sharpened stick. Can't even tell what its doing half the time or if it even properly supports my 4tb Seagates Vague error messages, endless demands to log in whenever I do anything...just a really rough bit of software. Using DNS-321 which from what I can see not that many people have..I can't even find any detailed reports from other owners. You'd need to be a Linux guru to get anywhere with this firmware, I think.

    Hi I boughted NAS D-link DNS 320L, with one WD 3TB hdd, which I placed to slot 2. I have trouble with Alt-F-0.1RC4.1-DNS-320L-rev-A1A2A3 (1).bin. I connected to NAS and upgraded firmware. Then restart and then start my trouble. All diods ( for USB, DISK1 and DISK2 ) glows red, and active slots ( in my case USB and DISK 2 ) glows blue at the same time. When I tried login to DNS,via administrator,nothing happend, my browser after some time writes that the page is unavailable. Can you help me solve this problem, at least return to the original state. Thank you very much for your help.

    it's a very good and stable project if you follow the installation guide step by step, it's fairly simple to setup all the necessary config before you will enjoy a brand new budget gigabit DNS with up to 3 HDD support. the speed before and after switch to Alt-F is about 4~6x speed jump... max out about 30-40MB/s =240~320Mbits.. over a gigabit lan. which is very good.. i would assume using ssd hdd will achieve higher speed.. though may also be capped by the DNS hardware itself (ram, cpu etc..) learn to use ssh commands to access the driver and you will also be able to transfer files to usb3 drives very quickly.. compared to over the gigabit lan.. wonder if there is a app that will allow testing of file transfer speed on alt-f? think there is.. just need to search a bit i guess

    I was about to scrap both my DLINK DNS-321 machines due to insufficient capacity. Thanks to the Alt-F project I can now drop in multiple 3TB or 4TB drives and extend their life. Interface is perfect and minimal. Speed is very good if not better than original DLINK firmware. Ease of install - Just Upload new firmware! In my case the hardware was A2. Worth following instructions. 15 minutes setup start to finish. A very useful project, and great service. THANK YOU ALT-F!

    Absolutely brilliant! I'd had my DNS-320L just a week before I became frustrated with the lack of functionality and the clunky UI. After a bit of searching I discovered Alt-F and it's transformed my budget NAS into a very useful little unit - not to mention how much snappier and responsive the UI is compared to the D-Link firmware. In no time I had it up and running with NZBGet, Sickbeard and Couch Potato and I can SSH to it from anywhere to see what it's up to. It's not necessary but I copied all my data off the existing disk first and let Alt-F format it before copying it back. The partitioning seems a lot tidier under Alt-F and the orange lights which were permanently illuminated are now showing the correct state. Awesome project - thank you!

    Gives us full control over the NAS. Many additional applications can be run.

    This is a great project. The 0.1 release is infinitely better than the factory's own. I was quite close to discarding my DNS-321, because even the latest factory firmware was never stable. Thanks to Alt-F (and all those who contribute to it), the box has a new lease on life.
