TAILMON TAILMON v1.1.0 -Jul 12, 2025- WireGuard-based Tailscale Installer, Configurator and Monitor (Now available in AMTM!)

[Viktor Jaep]

Looks like for whatever reason, the newly added Tailscale status check does not like you. Might need to back that out.

Rolled back using :

curl --retry 3 "https://raw.githubusercontent.com/ViktorJp/TAILMON/v1.0.19/tailmon.sh" -o "/jffs/scripts/tailmon.sh" && chmod 755 "/jffs/scripts/tailmon.sh"

Then did a reboot. Will monitor.

OK, that didn't work. It stopped emailing me failures every 5 seconds.... but still showed the memory error... So took off and nuked the whole site from orbit, only way to be sure.

After a full uninstall and reinstall of Tailmon+Tailscale all seems OK.

So are you running the latest version again without issues now? Nice job nuking the site from orbit. Always takes care of all the vermin.

Latest version (Tailmon 1.1.0 w/ Tailscale 1.84.0) = Yes

Without issues now = No

Its no longer in a restart loop, but its still erroring, possibly triggered by me logging in to AMTM/Tailmon:

EDIT: The above showed when I finished reinstalling at 2058 last night then logged in to check at 0837 this morning. I should add that despite this error it all seems to be working OK for the most part.

That is so strange. I can't duplicate this. I've tried launching from amtm, standalone, through screen, back & forth. I can't get any errors.

On my setup, I have it run at startup through screen... then, I will check on it every so often by using the command "tailmon -screen". I don't use amtm to run it. I just drop right to an SSH command.

What produces that runtime error you posted? How did you get that? Doesn't seem to be from the syslog?

 

[frazor77]

I'm going in via amtm, then it appears on the main tailmon screen, just not straight away (after ~20m or so)
