Mine has not! I'm still on beta 1 even though I'm on the beta track and set to check every night. What should I check!

What does your Tailmon log say from last night?

It ran at my chosen time and said a new version was available, Download/install. But it didn't download and install. I also the same notifications throughout the day other than my chosen time to check/install.

The easiest way to see what's happening is to run "Tailmon -autoupdate" in a separate ssh window. Let me know if anything weird pops up?

That worked. And I know why the update doesn't work! I checked my cron job and it is calling tailmon with the "-reset" option not the "-autoupdate" option. How did that happen?

Oh snap! Yep, I found that in the code... in one particular scenario, it was calling 'tailmon -reset"... but that command doesn't do anything. That's why it wasn't doing any update.

I've created a new beta to quickly patch that issue. I would remove your autoupdate cron schedule through Tailmon, and then re-add it once you have beta 3 installed.

Updated to b3 then disabled/reenabled autoupdate. The cron job is now correct! Thank you!!

TAILMON v1.3.0 Beta 3 is out! This is a emergency patch due the fact that it was incorrectly writing a bad cron command "tailmon.sh -reset", which just doesn't do anything. I believe it's something I copied over from VPNMON-R3, which does use the -reset switch. DOH.

NOTE: If you were running b1 or b2, please make sure you disable the autoupdate scheduler, then re-enable it so it writes the correct command.

v1.3.0b3 - (TBA)
- PATCH: Made an emergency patch update because one of the cron job conditions was accidentally calling 'tailmon -reset', which doesn't do anything. It was supposed to run -autoupdate.

Thanks for catching that!

That won't work if they have the broken cron job lol!

SHhhhhhhhhhhhhhhh!!! LET IT BE A SURPRISE!!

 

[Viktor Jaep]

That won't work if they have the broken cron job lol!

Was also going to mention... this is the inherent risk of running a beta! Lol

Hi All,

I have an ASUS Router with Tailmon installed, however its from over a year ago.

I hate to ask to avoid sounding dumb.... I know I need to update Merlin and Tailmon. Is there any special procedure?

Im just not sure if updating Merlin will mess up Tailmon on the usb drive, and what do I need to update on tne usb drive? Entware? Or is here an auto update option for existing Tailmon installs?

Thanks in advance

Hi All,

I have an ASUS Router with Tailmon installed, however its from over a year ago.

Could you please let us know which Router and which Merlin FW?

If Merlin is quite old, I'd stongly suggest updating that first and hard-resetting it (after FIRST saving all your settings as screenshots). Do not attempt to upload a saved config from the GUI from older FW to newer FW.

I'd also take screenshots of your various current settings screens in Tailmon so you can type these back in again., alhough the basic Tailmon setup is pretty automatic.

I think FW updates are covered much better in many other threads in this forum so I will not repeat here. Here is just one example. Here is another on best practice.

I hate to ask to avoid sounding dumb.... I know I need to update Merlin and Tailmon. Is there any special procedure?

No such thing as dumb, just learning at the speed that fits you best.

Well, the order is:

1. Update Merlin first (hard-reset if old, "dirty" flash over current FW if releatively recent). You will lose all your settings and Addons. @Viktor Jaep can tell you more about whether BackupoMon (an addon you could run BEFORE FW update) might let you put back the Addons but IIRC it is only advsied for theSAME FW; otherwise
2. Install amtm again. Install entware.
3. Reinstall your Add-ons via amtm, like Tailmon.

Im just not sure if updating Merlin will mess up Tailmon on the usb drive, and what do I need to update on tne usb drive? Entware? Or is here an auto update option for existing Tailmon installs?

If it's a dirty upgrade Tailmon should stay intact. In this (only) I'd suggest maybe just updating Tailmon from within Tailmon first.

From amtm menu, tm, C, 9 will update Tailmon and restart it.
From amtm menu, tm, C, p will update Tailscale and restart it.

Thanks in advance

You won't mess it up whichever way you go. I would probably update scripts and entware first with amtm.

Then update the firmware.

Once you're all set, you're welcome to enable autoupdate in TAILMON to help keep things updated.

New TAILMON v1.3.0 Release today... huge thanks to all the awesome beta testers helping smooth out the rough parts - @swejuggalo @Stephen Harrington @rung @jksmurf

What's new?!
v1.3.0 - (August 24, 2025)
- MINOR: Revamped the entire check updates/autoupdates process. Going into the "Check for Updates" section in the main setup / configuration menu, you now have the option to subscribe to either the BETA or STABLE (default) track. Once you are enrolled in either of these 2 tracks, TAILMON will only recommend updates and autoupdates for this specific track.
- PATCH: Fixed some minor UI changes
- PATCH: Fixed some of the logging messaging as it was still recommending an upgrade to a stable release even if you were enrolled in the beta track.
- PATCH: Made an emergency patch update because one of the cron job conditions was accidentally calling 'tailmon -reset', which doesn't do anything. It was supposed to run -autoupdate.

Download links (or use AMTM, or TAILMON Autoupdate!):

curl --retry 3 "https://raw.githubusercontent.com/ViktorJp/TAILMON/main/tailmon.sh" -o "/jffs/scripts/tailmon.sh" && chmod 755 "/jffs/scripts/tailmon.sh"

Significant Screenshots:

Update utility now showing BETA/STABLE track subscription options!
