# Meshbook A way to programmatically manage MeshCentral-managed machines, a bit like Ansible does.
What problem does it solve? Well, what I wanted to be able to do is to automate system updates through [MeshCentral](https://github.com/ylianst/meshcentral).
And many people will be comfortable with YAML configurations! It's almost like JSON, but different!
# Quick-start: The quickest way to start is to grab a template from the templates folder in this repository.
Make sure to correctly pass the MeshCentral websocket API as `wss:///control.ashx`.
And make sure to fill in the credentails of an account which has remote commands permissions.
Then make a yaml with a target and some commands! See below examples as a guideline. And do not forget to look at the bottom's notice.
To install, follow the following commands:
```shell git clone https://github.com/daanselen/meshbook cd ./meshbook python3 -m venv ./venv source ./venv/bin/activate pip3 install -r ./meshbook/requirements.txt ``` Now copy the configuration template from ./templates and fill it in with the correct details. The url should start with `wss://` and end in `control.ashx`.
After this you can use meshbook, for example: ```shell python3 ./meshbook/meshbook.py -pb examples/echo.yaml ``` # Example: For the example, I used the following yaml file: The below group: `Temp-Agents` has four devices, of which one is offline.
You can expand the command chain as follows:
```yaml --- name: Ping Multiple Points company: Temp-Agents variables: - name: host1 value: "1.1.1.1" - name: host2 value: "9.9.9.9" - name: command1 value: "ping" - name: cmd_arguments value: "-c 4" tasks: - name: Ping host1 command: "{{ command1 }} {{ host1 }} {{ cmd_arguments }}" - name: Ping host2 command: "{{ command1 }} {{ host2 }} {{ cmd_arguments }}" ``` The following response it received when executing the first yaml of the above files. ```shell python3 meshbook/meshbook.py -pb examples/variable_example.yaml -si -=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=- Running task: {'name': 'Ping host1', 'command': 'ping 1.1.1.1 -c 4'} -=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=- Current Batch: 1 Current response number: 1 Current Calculation: 1 % 3 = 1 Current Batch: 1 Current response number: 2 Current Calculation: 2 % 3 = 2 Current Batch: 1 Current response number: 3 Current Calculation: 3 % 3 = 0 -=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=- Running task: {'name': 'Ping host2', 'command': 'ping 9.9.9.9 -c 4'} -=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=- Current Batch: 2 Current response number: 4 Current Calculation: 4 % 3 = 1 Current Batch: 2 Current response number: 5 Current Calculation: 5 % 3 = 2 Current Batch: 2 Current response number: 6 Current Calculation: 6 % 3 = 0 -=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=- { "Batch 1": [ { "action": "msg", "type": "runcommands", "result": "PING 1.1.1.1 (1.1.1.1) 56(84) bytes of data.\n64 bytes from 1.1.1.1: icmp_seq=1 ttl=59 time=6.73 ms\n64 bytes from 1.1.1.1: icmp_seq=2 ttl=59 time=6.37 ms\n64 bytes from 1.1.1.1: icmp_seq=3 ttl=59 time=6.31 ms\n64 bytes from 1.1.1.1: icmp_seq=4 ttl=59 time=6.44 ms\n\n--- 1.1.1.1 ping statistics ---\n4 packets transmitted, 4 received, 0% packet loss, time 3004ms\nrtt min/avg/max/mdev = 6.312/6.461/6.727/0.159 ms\n", "responseid": "meshctrl", "nodeid": "MSI" }, { "action": "msg", "type": "runcommands", "result": "PING 1.1.1.1 (1.1.1.1) 56(84) bytes of data.\n64 bytes from 1.1.1.1: icmp_seq=1 ttl=57 time=6.18 ms\n64 bytes from 1.1.1.1: icmp_seq=2 ttl=57 time=6.17 ms\n64 bytes from 1.1.1.1: icmp_seq=3 ttl=57 time=6.17 ms\n64 bytes from 1.1.1.1: icmp_seq=4 ttl=57 time=6.27 ms\n\n--- 1.1.1.1 ping statistics ---\n4 packets transmitted, 4 received, 0% packet loss, time 3004ms\nrtt min/avg/max/mdev = 6.170/6.200/6.274/0.042 ms\n", "responseid": "meshctrl", "nodeid": "raspberrypi5" }, { "action": "msg", "type": "runcommands", "result": "PING 1.1.1.1 (1.1.1.1) 56(84) bytes of data.\n64 bytes from 1.1.1.1: icmp_seq=1 ttl=57 time=6.33 ms\n64 bytes from 1.1.1.1: icmp_seq=2 ttl=57 time=6.13 ms\n64 bytes from 1.1.1.1: icmp_seq=3 ttl=57 time=5.92 ms\n64 bytes from 1.1.1.1: icmp_seq=4 ttl=57 time=5.91 ms\n\n--- 1.1.1.1 ping statistics ---\n4 packets transmitted, 4 received, 0% packet loss, time 3005ms\nrtt min/avg/max/mdev = 5.908/6.072/6.334/0.173 ms\n", "responseid": "meshctrl", "nodeid": "server" } ], "Batch 2": [ { "action": "msg", "type": "runcommands", "result": "PING 9.9.9.9 (9.9.9.9) 56(84) bytes of data.\n64 bytes from 9.9.9.9: icmp_seq=1 ttl=61 time=10.4 ms\n64 bytes from 9.9.9.9: icmp_seq=2 ttl=61 time=9.96 ms\n64 bytes from 9.9.9.9: icmp_seq=3 ttl=61 time=9.83 ms\n64 bytes from 9.9.9.9: icmp_seq=4 ttl=61 time=9.96 ms\n\n--- 9.9.9.9 ping statistics ---\n4 packets transmitted, 4 received, 0% packet loss, time 3005ms\nrtt min/avg/max/mdev = 9.830/10.036/10.396/0.214 ms\n", "responseid": "meshctrl", "nodeid": "MSI" }, { "action": "msg", "type": "runcommands", "result": "PING 9.9.9.9 (9.9.9.9) 56(84) bytes of data.\n64 bytes from 9.9.9.9: icmp_seq=1 ttl=60 time=10.8 ms\n64 bytes from 9.9.9.9: icmp_seq=2 ttl=60 time=10.6 ms\n64 bytes from 9.9.9.9: icmp_seq=3 ttl=60 time=10.5 ms\n64 bytes from 9.9.9.9: icmp_seq=4 ttl=60 time=10.5 ms\n\n--- 9.9.9.9 ping statistics ---\n4 packets transmitted, 4 received, 0% packet loss, time 3005ms\nrtt min/avg/max/mdev = 10.450/10.593/10.773/0.118 ms\n", "responseid": "meshctrl", "nodeid": "raspberrypi5" }, { "action": "msg", "type": "runcommands", "result": "PING 9.9.9.9 (9.9.9.9) 56(84) bytes of data.\n64 bytes from 9.9.9.9: icmp_seq=1 ttl=59 time=10.8 ms\n64 bytes from 9.9.9.9: icmp_seq=2 ttl=59 time=10.6 ms\n64 bytes from 9.9.9.9: icmp_seq=3 ttl=59 time=10.9 ms\n64 bytes from 9.9.9.9: icmp_seq=4 ttl=59 time=10.7 ms\n\n--- 9.9.9.9 ping statistics ---\n4 packets transmitted, 4 received, 0% packet loss, time 3006ms\nrtt min/avg/max/mdev = 10.600/10.750/10.898/0.117 ms\n", "responseid": "meshctrl", "nodeid": "server" } ] } All tasks completed successfully: Expected 6 Received 6 ``` The above with `-si` is quite verbose. use `--help` to read about parameters. # Important Notice: If you want to use this, make sure to use `NON-BLOCKING` commands. MeshCentral does not work if you send it commands that wait.
A couple examples of `BLOCKING COMMANDS` which will never get back to the main MeshCentral server: ```shell apt upgrade # without -y. sleep infinity ping 1.1.1.1 # without a -c flag (because it pings forever). ```
