NTP / Time Sync NSLU2

    I've been using the NSLU2 for more than 6 months now, and find it simple, reliable and valuable file server for sharing files among several machines on our home network (I tried two other NAS devices before this one.)

    However, as of recent, I would like to sync files between the NSLU2 and machines on our home network. I would like to use the file timestamp for the syncing. I can easily use NTP to set all the machines on the network to a known time (easily within a 1 second of each other).

    But, I have to set the time on the NSLU2 manually. I find that interface rather combersome and not very repeatable, especially since it doesn't allow entry of time to the second, only the minute.

    Is there not some way to have the NSLU2 sync with an NTP server occasionally? Or, is there someway to telnet into the NSLU2 and set the time manually ... so it can be done accurately within a second or two.

    I'm well aware of the UnSlung firmware and community, but I don't have the time to invest into working the device to that level. So, I'm asking if anyone knows if there is a way to do this with the stock firmware ... 2.3R63.

    If not, anyone know if this is a feature that may be added in a future firmware. There hasn't been a firmware update in a year now, so I'm kinda doubting it.

    Looking at other NAS devices on the market, they seem to have the option to NTP time sync, so I'm surprised not to see it in the NSLU2.

    Thanks for any assistance.

    I know there was a 3rd party project for this product.


    v2.3r72 is a beta i can get for you if you like. i do not however know the changes.

    Thanks for the reply. As I noted in my post, I'm already aware of the efforts of the UnSlung group (at nslu2-linux.org as you noted). With 3 little kids at home, I just don't find the time to work on the NSLU2 to that level.

    I had also noted the beta firmware you posted in this linksysinfo.org thread some time ago. No one has posted any useful information about that firmware since April, so I'm not yet too eager to try it. I've posted the same time syncing question to that thread.

    Should this help anyone else:

    Linksys support confirmed that there are no options to set the NSLU2 time with any resolution greater than 1 minute. From the NSLU2's web page, this seems reasonable as it only gives the option to adjust to the minute.

    However, if you actually read the manual, you see the Setup Wizard showing the time adjustable to the second ... so I've found this to be misleading. What I've learned is that no matter what you enter in the Setup Wizard for seconds, either the wizard or the NSLU2 itself truncates the seconds and just sets the time to the minute with 00 seconds.

    Trying to set the time on the NSLU2 as precisely as possible, I've had the best luck with the Setup Wizard. Using the wizard, enter the time for the next upcoming minute, and then click 'Ok' in the wizard about 4 - 5 second before the minute starts.

    For example, Let's say you want to set the NSLU2 time to 11:10:00. Enter this time into the wizard, click next, then click Save, this will bring up a popup window with OK or Cancel. When you know the actual time is in the range of 11:09:55, plus or minus a couple seconds depending on your network speed, etc, click the OK button.

    This is the best I've been able to do. I can also get close using the web page interface, but I've found use of the Setup Wizard more consistent.

    It's a darn shame that a file server like this doesn't have better time management. I've asked support to consider adding it, but given the NSLU2 is more than 2 years old and they haven't added it yet, I doubt we'll see any updates to the time management.

    I'm in agreement. Worse still is the fact that my NSLU2 (and I imagine I'm not alone here) loses time hand over fist. You would expect better.

    You are definitely not alone. The changelog as far back as v23R25 says "fixed the time that made it lose minutes etc etc...", but I have the v23R72 beta installed and it still loses time badly. Not only that, when it resets itself, it goes all the way back to 1970. Great. If Thibor can add this to Thibor 15c for the WRT54G/GS range, surely Linksys can add it to the NSLU2....can't they? I was hoping unslung would be a bit more like Thibor 15c with a few more GUI type options, but like Syncer I have two small kids at home and just don't have the time to get into the whole unslung experience.
