"Tailscale is not online" problem

@chudak said in "Tailscale is not online" problem:
API key does not exis
I regenerated Auth keys and got it online, but not local local hosts resolve when connected, interesting...
-
I have had several occasions where the Tailscale installed on my pfSense CE (Zimaboard 432), failed to connect to my Tailnet following a pfSense Restart and it last night's instance the Tailscale Status was reporting my "API key does not exist"...
Although I tried Restarting the Tailscale Service a few times, my pfSense's Tailscale was failing to connect to my Tailnet...
Then I tried a Tailscale Service "Stop", followed by a Tailscale Service "Start" and curiously this time Tailscale was able to connect to my Tailnet!!!
Although my last resort would have been to generate a "New" Key, in this case I did NOT have to, since API key following the Stop/Start the API key did exist???
NOTE: Although I did have "Service Watchdog" running and Tailscale was selected with "Notification", it appears the Service was still running...

For those interested, I got a script here in the forum and changed it a little bit to work with tailscale and to check the connectivity every two minutes. It restarts the service if the ping fails.
#!/bin/sh ALLDEST="headquarters" COUNT=1 while [ $COUNT -le 2 ] do for DEST in $ALLDEST do tailscale ping --c 1 $DEST >/dev/null 2>/dev/null if [ $? -eq 0 ] then exit 0 fi done if [ $COUNT -le 1 ] then /usr/local/sbin/pfSsh.php playback svc stop tailscale # /usr/local/sbin/pfSsh.php playback svc restart tailscale sleep 5 /usr/local/sbin/pfSsh.php playback svc start tailscale sleep 10 exit 1 fi COUNT=`expr $COUNT + 1` doneThen, chmod +x this script, install cron package and create a routine to run every 5 minutes, or 2 minutes, you choose.
If you improve this script somehow, please post the changes.

Is ALLDEST="192.168.10.1" your TS IP?

This is the remote site LAN IP address (other pfsense).
This network is advertised through tailscale.You can use any ip address that tailscale is expected to ping when it is online.

It restarted TS for me all the time regardless of the condition
./restart_tailscale
Attempting to issue stop to tailscale service...tailscale has been stopped.
Attempting to issue start to tailscale service...tailscale has been started.

@chudak What is the output of the command: tailscale ping IP that you are trying to ping ?

I think you are missing a value for "--c "
But the line
tailscale ping --c 3 --timeout 2 XYZstill does not work for me :( -

hmm, I think I may have provided the previous script, the one I was testing before deployment, let me search for the fixed one.
Edit: https://tailscale.com/kb/1080/cli#ping
You can ping a 100.x.x.x address or the node's name directly.
Also, if I remember correctly, try --c1(without space),Edit2: script is updated in the previous post.

nice, good job for reporting that.
Did you manage to use the script ?

I thought you were looking for a better version of the script.
Were you?Did you see the Christian McDonald said it’s not a bug?
Apparently the current widget reports only about if the TS process running, no wonder it’s not useful -

Were you?I updated it, check above. Replace headquarters for the node's name.

Maybe for the release after 24.03 I'll do a proper Tailscale widget. As I said in the Redmine, service status in pfSense can only report service running or not running. There are two Tailscale binaries, tailscale and tailscaled. tailscaled is the service and tailscale is the front end. By design tailscaled has to be running to receive commands from tailscale, even before it's authenticated and connected.

Pls do!
This seems like a simple UI bug but in fact it’s very misleading.
I suspect that start/stop from the current widget also non functionalTIA

@chudak said in "Tailscale is not online" problem:
--timeout option seems to be broken. Did you get it to work?
The default is fine, 5s.
The "Tailscale is not online" issue happens pretty fast, so there is no need for the timeout option as I see it.. -
Hi Guys,
For anyone interested: here is the script that I used that is working 100%.
The --timeout 2 is not a flag within the tailscale CLI commands.

whois Show the machine and user associated with a Tailscale IP (v4 or v6)Anyone has comments, please let leave them.
Note: you must make it executable with chmod +x and I just modified the above script to make it work for my use case. The tailscale node keeps on falling off (exit node unavailable) after either a reboot or it fails after a few days ofd being online. Added error checking display message.
@cmcdonald, this is still occurring in the 24.03 BETA (latest revision) as you are aware.

Today TS is again shows
Tailscale is not online. Refresh or check the Tailscale status page.The scrip says
tailscale has been started.But in fact TS is down :(
WTH
