      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 ?

        dead on arrival, nowhere to be found.

          I think you are missing a value for "--c "

          But the line tailscale ping --c 3 --timeout 2 XYZ still 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.

            dead on arrival, nowhere to be found.

                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

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

                    I hope they include this in the next pfSense upgrade.

                      The scripts worked, thx!

                      --timeout option seems to be broken. Did you get it to work?

                        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 functional

                          TIA

                            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.

                              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 :(

                                  @chudak 4 months later, I think this time frame tell us something.
                                  Problem should be with tailscale itself, or the other node..

                                    Frankly, there is nothing to update and I still did not get to the bottom of it.

                                    TS sometimes is up and running and very stable for long periods. And then it gets flaky and can't connect.

                                    I do run "restart_tailscale" script in crontab, so I assume it makes it start.

                                    But in general, I am puzzled ...

                                    Any clues?

                                      Any logs when the problem starts ?
                                      What happens when you try to ping the other node ?
                                      What status it shows in the GUI ?

                                      I have been using that script with the following scenario, which works fine:

                                      I have a customer that runs multi WAN in their headquarters.
                                      One of this links is a CGNAT and other is not.

                                      The branch office connects directly to the primary non CGNAT link (I have opened a port in the firewall for that connection).
                                      If a link failover happens in the headquarters, sometimes it loses connections to the TS network and that's when the script "fixes" the problem by forcing the headquarter firewall to restart the service but now using the CGNAT link, thus connecting through the TS node and not a directly connection anymore.

                                      The reverse is also true, I mean, when the primary link which is not CGNAT comes back online.

                                      dead on arrival, nowhere to be found.

                                        I don't know exactly where to look :(

                                        On a high level, only what I see is TS service is green (which is confusing but that's in a different thread and unrelated) and TS connection status is down.

                                        My use case is:

                                        pfS runs TS
                                        iPad runs TS
                                        iPhone runs TS
                                        Windows 11 VM runs TS

                                        So when psF is down, others actually work fine.
                                        I even noticed that routes get resolved.

                                          TS connection status is down.

                                          isn't the script working for that ?
                                          script tries to ping and if it fails, it will restart the service.

                                            That's an interesting part.
                                            Yesterday I found TS down

                                            I tried to start it manually, and switched Kea DHCP to ISC DHCP and back, removed /tmp/kea4-ctrl-socket.lock and could not make it start.

                                            Then today in the morning - everything is up and running normally

                                            ??!!
