Updater

when we start an update the reverse tunnel opens, but after on pheromon there is this error:

admin client data received

This problem comes from pheromon, not 6brain.

We need to append theses lines in /etc/ssh/sshd_config on the server:

# In order to enable reverse SSH from sensor to docker
AllowTcpForwarding yes
GatewayPorts yes

Then restart the ssh server

sudo service ssh restart

@4rzael you mean you managed to solve the problem of the update ? should I add this to the server ?

[4rzael]

I still have an error, but it allows the docker to connect to the sensor.

[vallettea]

awesome. Just changed the ssh config on the server

[4rzael]

Okay, it should work.

[4rzael]

Changing the configuration file on the server fixed this.
