Realtime additional information of a device

[Skyline643]

I would like to know if there's any possibility or progress to read out some custom information and show it realtime in the overview or a custom colums like you have OS or Address, ... ?
We use MeshCentral and the MeshAgents on multiple Linux Ubuntu devices. and it would be great if we can get some additional information like:

• The result of a command like: dpkg -s networkoptix-mediaserver | grep "Version"
• This command gives for example a result like: "Version: 6.0.6"

The same with the disk state of a device. MeshCentral shows the disks and capacity but we can't see if the state of the disk is ok or not.

This would help us a lot. So we can filter or see which devices have an old version or have issues with disks.

no this type of thing isnt possible,
remember meshcentral is designed as a remote support application
but people keep thinking its turning into a remote management application and we arent.
the only way to do this is through automation and creating your own dashboard etc
use the websocket api to connect to meshcentral, get ya list of nodes, pick a node, then use the runcommands to run your command and get a reply, then with that reply, build your own dashboard etc

Ok thanks. I will give it a try to read this out. If someone has any tutorial or guide for this, always welcome :-)

basically open a websocket to https://my.domain.com/control.ashx
make sure to include the header x-meshauth: (BASE64 your USERNAME),(BASE64 your PASSWORD)
then over the websocket call {action:'nodes'} and you will get an event back and in there will be the nodes you can loop over to get all their ids etc
then once you have a device in question, call over the websocket
{ action:'runcommands', nodeids:['nodeidgoeshere'], type:0, cmds: 'YOURCOMMANDHERE', responseid:'myapp', runasUser: 0, reply: true }
then wait and you will get an event back with the reply of the command

bung that into ai to help you build something 👍

Ok, I'm a bit further, but a bit stuck with the software token.
I ran the command: node node_modules/meshcentral --loginTokenKey and got a token.
I added the token to my .env file which I use to let the websocket connect to Meshcentral (everything is on the same Ubuntu virtual machine).

When I try wscat -c wss://mydomain:port/control.ashx -H "x-meshauth: MYSECRETTOKEN" --no-check I got the following errors:

Connected (press CTRL+C to quit)
< {"action":"close","cause":"noauth","msg":"noauth-2c"}

In the config.json file i added the following into the 'settings' section: "allowsoftwareintegration": true
I think that might be the reason why it doesn't work to get info out of Meshcentral. Maybe this is not the right name or right thing I need to add?

The Websocket connects perfectly - no errors there.

noauth-2c means invalid authentication
OR you havent sent the correct number of values in the x-meshauth
example x-meshauth: dXNlcm5hbWUxMjM=,cGFzc3dvcmQxMjM=
translates to username is username123, password is password123
you dont base64 encode all of it, only the user or pass, NOT the , thats in between

edit: also the is no value allowsoftwareintegration in the config.json (PLEASE IGNORE AI SUGGESTIONS!)
also use https://config.meshcentraltools.com to check for possible config.json values

I used the official parameters instead, but still stuck to log in. I don't use user & passwordt, but an auth token generated via the cli. Unfortunately, still the same error (noauth-2c):

WS connected
Feb 09 16:34:26 node[4407]: WS message received: {"action":"close","cause":"noauth","msg":"noauth-2c"}

It seems that the generated auth key with the oneliner: node node_modules/meshcentral --loginTokenKey is not been accepted somewhere.

This is the part I added in the config.json:

{
"settings": {
"WANonly": true,
"port": 443,
"aliasPort": 8443,
"allowLoginToken": true
}
}
