How to setup network ? #8

saberioon · 2021-01-29T09:08:13Z

How to connect to the server for transmitting data automatically? I understand that the config file has the address and name of the folder for storing data but what about the password? Also How to force to upload data? Probably you write it somewhere but I couldn't find it. Your advice is appreciated

javierconcha · 2021-01-29T15:44:13Z

I also wonder about this. I remember from last week meeting that NPL or RBINS have to give us an account on the server. Is this related to that @clemgoyens @shunt16?

Hi Javier, Hi Mehdi,

Yes indeed, NPL will provide GFZ an account on the NPL server and Alex should give you the instructions on how to transfer the data automatically from the rugged PC to the server (I have some notes on how to do it but these are incomplete). For the water sites I still need to check how I can manage the RBINS server (sorry it has been on my to-do list for so long now!!). I will make sure the RBINS server will be able to welcome data from the water sites in February! Once I have tested it I will make you an account Javier and let you know about how to implement it!!

Hi all !

@saberioon : yes, you well understood about the configuration file. For the password step and automatic mode at boot time, you can try this :

sudo ./install/08_setup_server_communication.sh

When it asks about ssh passphrase and file location, let it empty (just press enter)

saberioon · 2021-02-02T14:22:18Z

Still, I cannot push readings automatically to the server even after I set it up!

this is output of sudo ./install/08_setup_server_communication.sh

Hello @saberioon ,

Can you test the following please :
cd hypernets_tools/
rm -rf LOGS/
sudo ./install/08_setup_server_communication.sh

saberioon · 2021-02-03T08:49:35Z

sudo ./install/08_setup_server_communication.sh

I have this outputs:

I guess there is a trailing space in your config file after the IP address ?

corizzi · 2021-02-03T10:51:23Z

should be fixed now, thanks for the feedback

saberioon · 2021-02-03T10:56:58Z

@corizzi
first I manually remove space after the IP and it successfully synced.

after your fix, I have tested it again and it successfully synced 👍🏼

Hi @corizzi ,

Somehow the communication between system and server interrupted and I cannot make the connection again!
this is the message in hello.log :

Hi Mehdi,

I had the same error at Blankaart. I thought it was an issue with my account but apparently not.
Can you check if you can sync

saberioon · 2021-03-01T15:42:18Z

@clemgoyens
Nope, It is not syncing!

clemgoyens · 2021-03-01T17:37:04Z

Oops sorry Mehdi, I didn't realise my message left. I was looking for the command I used to sync (and which worked while I had the same error as yours). Ok maybe @corizzi can help with it...
Also can you connect from the rugged PC to the NPL server using your password and simple ssh command (ssh [account_name]@[npl server])?
