Hamachi not powering on after computer restart

Can you please provide the option to power on hamachi from a command line?  This is really becoming a problem, here is what happens: workstation restarts, due to windows operating system update, env...

    So, I've figured out a way to deal with this.  I wrote a windows service that monitors the logmein service and it's power on status.  If either get turned off my service restarts them.  So far has been working very well and ended the random shutdowns that can happen.

    Hi Jerry. Can you share more details of how you wrote this Windows service to monitor the LogMeIn application's power status? I've been encountering the same issue. I am able to tell whether the Hamachi service is running, but have been unable to determine whether it's powered on via Windows.

      I can't speak for Jerry but an easy way to check the status of the Hamachi connection is 

      c:\Program Files (x86)\LogMeIn Hamachi\x64\hamachi-2.exe --cli list

      Exclude the full pathname if appropriate in your specific case, etc etc. If the VPN is currently off, this will be the result

      You have no networks.

      If the script picks that up as a response, have it run

      c:\Program Files (x86)\LogMeIn Hamachi\x64\hamachi-2.exe --cli logon

      And that's the equivalent of pressing the power button on the UI. That way whenever the Hamachi is disconnected for whatever reason, it will attempt to reconnect and log back on without the need of the UI.

       

      For some reason on a new computer that I installed Hamachi on, it seems to randomly decide not to auto-connect (aka "Power" on) and it would be offline, requiring me to press the power button on its UI. Other times it would auto-connect just fine. Apparently this is controlled via a config file some place but the fact that it isn't being consistent was something I found odd. So what I did was create a task run in Task Scheduler to execute that previous command (hamachi-2 --cli logon) set to run "At Startup", set it to run with Administrative privileges whether a user is logged in or not, and set a Condition for it to run after getting a Network Connection with the device that provides internet access. This way Hamachi is already connected to the VPN before anyone logs on (assuming the person doesn't log in fast enough to get ahead of it). From now on I won't have to deal with the randomness of it not auto-connecting or worry about its configuration set to do so.

        Thanks nawcom  for sharing this. This is extremely helpful and was not able to find any evidence of these functions existing when searching documentation. Really appreciate it!

      So there is a an ini file that hamachi uses, in the windows serviceprofiles area.

      h2-engine.ini

      In this file, there is a reconnect line

      Reconnect 1  means powered on

      Reconnect 0 means powered off

       

      Basically the service I wrote polls that file every so often, if it finds the state powered off, it stops the service, changes that line, and then restarts the service.   It also checks to make sure the service is running and also starts it up if the service is stopped.  I also keep the hamachi in "do not self update" mode...

       

      The other suggestion is good too.
