Hamachi randomly disconnects on Ubuntu 20.04 (and Chrome OS Flex)

[Michael_Logies]

I deinstalled Haguichi, problem solved. I have no time for playing around too much. At the moment I`m using Chrome Remote Desktop (CRD) instead of Remmina over Hamachi, because it is faster, shows better quality.

Hola. Efectivamente la GUI interrumpe el servicio.  Nosotros tenemos redes con 36 usuarios y hemos optado por no usar el GUI en Linux, sino todo por linea de comando y funciona muy bien , es muy estable y no es dificil de configurar.

Hello. Effectively the GUI breaks the service. We have networks with 36 users and we have chosen not to use the GUI in Linux, but everything through the command line and it works very well, it is very stable and it is not difficult to configure.

i will like to confirm haguichi is really the problem because the developer is very collaborative and can fix this is this situation if is haguichi the real problem. The gui with the commands editable is a great tool, so why have interest in this working as expected.

How can i test the service dont crash in an easy way? where is the crash logged? Which file?

Best regards

En mi caso, cerré la aplicación haguichi e incicié por terminal el servicio hamachi. el resultado es la estabilidad del servicio sin la GUI, y por terminal puedes ver el estado del servicio también

In my case, I closed the haguichi application and started the hamachi service by terminal. the result is the stability of the service without the GUI, and by terminal you can see the status of the service as well

Here the commands I use, all with sudo

hamachi login
hamachi set-nick PC-NAME
hamachi set-ip-mode ipv4
hamachi attach ACCOUNT_TO_ATTACH

To view status

sudo hamachi

[germangentile]

I already knew the commands. What i need is a log service showing crash of hamachi to verify behavior with and without the GUI.

Haguichi stinks

I already emailed the developer of Haguichi and got 2 answers:

Hello Michael,

Good to hear that Haguichi works on Chrome OS (Flex). But I cannot fully
verify Chrome OS as a supported system because I don't have a Chromebook
myself.

Hamachi crashing on Ubuntu 20.04 (or any other later version) is very
well known and documented in many places including the very same thread
you linked to and responded in:
https://community.logmein.com/t5/LogMeIn-Hamachi-Discussions/Hamachi-randomly-disconnects-on-Ubuntu-...
https://github.com/ztefn/haguichi/issues/38
https://github.com/ejtagle/hamachi-fix-ubuntu20.04-or-newer

In short, Hamachi is incompatible with the newer glibc version shipped
in Ubuntu 20.04 which causes it to crash when executing certain
instructions. LogMeIn was made aware of the problems and didn't give a
**bleep** about it. And now Hamachi is owned by a company called GoTo which
doesn't even list Hamachi as one of its products:
https://www.goto.com/products

So claiming that Haguichi is the origin for these problem is frankly
quite absurd. Haguichi merely sends commands to the Hamachi command line
interface to get the info it needs to display in the GUI. If that causes
Hamachi to crash faster then the only options that remain is either turn
of network list updates in Haguichi's preferences and refresh the
network list manually when needed, or don't use Haguichi at all and use
Hamachi command line interface yourself:

hamachi -h

Cheers,

Stephen

Hi Michael,

Haguichi has implemented an inhibitor
<https://github.com/ztefn/haguichi/blob/master/src/inhibitor.vala> for
exactly this scenario since version 1.3.7
<https://haguichi.net/news/release137/>. It listens to a DBus signal
that the system is about to sleep or wakeup and then runs the hamachi
logout command to properly stop the connection before going into sleep
or runs hamachi login when internet connection is available after wakeup

On your Linux subsystem there are likely no such DBus signals because
its unaware of Chrome OS going to standby.

Cheers,

Stephen
