TAILMON TAILMON v1.3.0 -Aug 24, 2025- WireGuard-based Tailscale Installer, Configurator and Monitor (Available in AMTM!)

[swejuggalo]

Err - I don't know. How do I check?

I used amtm, then "tm", then "C", then option "9"

AMTM, U

 

[alan6854321]

Yes, that says.

tm open TAILMON 1.2.0 -> 1.3.0

What happens if you run this from the router console?

curl https://raw.githubusercontent.com/ViktorJp/TAILMON/main/version.txt

 

[alan6854321]

1.3.0

 

[swejuggalo]

Yes, that says.

tm open TAILMON 1.2.0 -> 1.3.0

If checking again within TM does not work, perhaps you can use this outside of AMTM.

Download links (or use AMTM, or TAILMON Auto update!):
 
curl --retry 3 "https://raw.githubusercontent.com/ViktorJp/TAILMON/main/tailmon.sh" -o "/jffs/scripts/tailmon.sh" && chmod 755 "/jffs/scripts/tailmon.sh"

But you might want to confirm with the author why this happens so a fix can be made.

1.3.0

I've seen instances where for some reason permissions on files change, and can't overwrite it locally. Can you check this?

cat /jffs/addons/tailmon.d/version.txt

And if that still comes back with "1.2.0", try deleting that file.

rm /jffs/addons/tailmon.d/version.txt

Then try updating within TAILMON again?

 

[swejuggalo]

Interesting. Every time I start Tailmon with TM the latest beta of Tailscale the watchdog restarts it, even though it is properly running.

Can anyone confirm?

 

[swejuggalo]

A very minor issue. Still claims it's beta 3 in the mail.

When did it update to 1.3.0? Before or after 12:20?

 

[alan6854321]

Well, I deleted /jffs/addons/tailmon.d/version.txt

and the new version appeared when I ran 'C' followed by '9'
I said 'y' to download it and got this...

Downloading TAILMON v1.3.0

But the version stays at 1.2.0.

I've tried the process several times and the download always happens but the version doesn't update.

Yesterday

I forced a reflash of the update. Beta tag is gone

 

[swejuggalo]

Hmm...

I have a feeling the same thing is happening with your tailmon.sh file. I'm wondering if it's somehow read-only.

See if this command will update it?

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

If it's still stuck on 1.2.0 after running that, I would go through the same process of deleting it, and running the command again, so:

rm /jffs/scripts/tailmon.sh

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

If this is happening with TAILMON, you've got to wonder what else is happening on your router. Just hope something catastrophic isn't going on, and would definitely keep an eye on your syslog?

 

[Viktor Jaep]

Hmm...

Sometimes, when you kill the TAILMON script, it somehow can take the Tailscale services along with it. If you (E)xit cleanly, most of the time, it keeps those services running. That's why I just leave it running under Screen... so it's always on.

 

[alan6854321]

OK - I tried the first 'curl' command and it seemed to work.
TM now reports it's running 1.3.0 and an upgrade attempt tells me I'm running the latest STABLE release.

I have had problems with updating Tailmon before, sometimes it takes several attempts before the new version 'takes'.

Nothing odd in the syslog.

The fact that it takes a few times to 'take' is really pretty odd.

The command I shared with you above is exactly the same thing the script runs to update itself.

I'll take another look at the update process in more detail to see if anything stands out. Throughout testing, I've never encountered a situation where it didn't update right there on the spot. I appreciate your feedback on all this!

EDIT: I think there's probably some opportunity for more error checking on the curl downloads in case something isn't coming over correctly and just not telling you about it. I'll work on that.

It does not happen when I exit, it happens right after attempting to open with TM.
I can even connect with the router as exit point, run AMTM, TM and see it disconnect.

Something I haven't mentioned is that the whole system is incredibly slow.
E.g.
in amtm, I type "tm"
nothing happens for 30 secs, then the screen goes blank
again, nothing happens for 30 secs, then the TAILMON screen appears

from the config screen, I type '9'
nothing happens for 30 secs, then it says "You are on the latest STABLE version!"

I'm guessing there's a couple of 30 second timeouts in there somewhere.

If this happens regardless on how you connect to the router, wired or wireless, with or without VPN it seem to be something much wider than Tailmon/Tailscale.
