Post by RyanYang »

Target Users:

Note:
If your TOS version is TOS 6, please refer to the TOS 7 update instructions first.
Important: This update is only applicable to TOS 7.0.0746 and newer. Users with older versions must first upgrade to 7.0.0746 before applying this update.

Here, we sincerely thank @nitzer71, @JSCFORCE, @greentower, @Gremlin, @qidi4feet, @Konstantin, @rfbjr, @sianderson, @snapsh0t, @k.wechselberger, @Zymphad, @crisisacting, @EgorA, @apvm, @DCCentR, @joka388, @Nitrokalel, @dgmigdot, @OlRedRooster, @Hendrik, @OttO1916, @ambul and others for your sharing and feedback. Your support helped us quickly identify and fix multiple issues.

Update Notes
Bug Fixes:
1. Fixed an issue where icons might display abnormally after multiple switches when multiple tabs were opened in File Manager.
2. Fixed an issue where MTU configuration became invalid after system reboot when MTU was set and OVS function was enabled.
3. Fixed an issue where system log time was one hour earlier than daylight saving time.
4. Fixed an issue where the Apply button was not properly grayed out when the device name was not modified.
5. Fixed an issue where OpenClaw could not delete users properly via CLI.
6. Fixed an issue where OpenClaw could not create shared folders properly via CLI.
7. Fixed an issue where IP address could not be obtained properly after re-enabling a disabled network interface when directly connected to a computer.
8. Fixed an issue where plugging or unplugging a USB device caused ongoing SMB transfer tasks to be interrupted.

Installing onto test bed units currently; will post if any issues appear in the coming days.

When will a .ins image become available for clean installs & the initboot that's being issued privately for TOS 7, will that become a public build in the coming weeks/months?

Trying to strategize future unit deployment processes & would like a clearer timeline regarding those two aspects.

3. Fixed an issue where system log time was one hour earlier than daylight saving time.

This is now correct in the system log (hurray) but still wrong in Media index last run.

Hi. As with upgrading to TOS 7, there are a few things to keep in mind when installing TOS 7 by flashing a new USB boot drive.
The new USB boot image specifically for TOS 7 can now be downloaded here:

Updated F2-221, F5-221, F2-424, F2-425Plus. And Tnas-PC*

Now both -424 and -425 show a LAN1 connection as well as alb-Bond on Lan1 and Lan2. While this is not a direct issue it is **** annoying.
The Good News: New Version of Tnas-PC no longer shows the errant LAN1 connection in it's listing. Plus WOL now appears to work on alb-Bond connections.

*Is 'Surrogate Com' a part of Tnas-PC? My windows 11 system always has issues with it while updating Tnas-PC. If I opt to try and close, it fails. If I opt to ignore it, it appears to update - but that does not feel "good". I have taken to deleting Tnas-PC entirely and re-installing it. Makes me feel better about the installation, but seems totally unnecessary. The down-side is that details that should be remembered also are deleted - I don't use Terrasync options, but I am guessing that some of that info may be 'lost' as is 'Access History'.
