## Installation

```python
pip install dnsdist_console
```

## Generate key

Generate a shared secret key.
It will be used between the client and the server.

```python
from dnsdist_console import Key

k = Key().generate()
print(k)
OTgmgAR6zbrfrYlKgsAAJn+by4faMqI1bVCvzacXMW0=
```

The command in one line 

```bash
python3 -c "from dnsdist_console import Key;print(Key().generate())"
```

Save-it in your `/etc/dnsdist/dnsdist.conf` with the `setKey` directive.

```
controlSocket('0.0.0.0:5199')
setKey("GQpEpQoIuzA6kzgwDokX9JcXPXFvO1Emg1wAXToJ0ag=")
```

## Handshake

```python
from dnsdist_console import Console

console_ip = "127.0.0.1"
console_port = 5199
console_key = "GQpEpQoIuzA6kzgwDokX9JcXPXFvO1Emg1wAXToJ0ag="

console = Console(host=console_ip,
                  port=console_port, 
                  key=console_key)
```

## Run command

Please refer to the dnsdist documentation for available commands.

```python
o = console.send_command(cmd="showVersion()")
print(o)
dnsdist 1.4.0

```

## Get statistics

Get statistics from dnsdist in JSON format. 

```python
from dnsdist_console import Console
from dnsdist_console import Statistics

# dnsdist console
console_ip = "10.0.0.27"
console_port = 5199
console_key = "OTgmgAR6zbrfrYlKgsAAJn+by4faMqI1bVCvzacXMW0="

c = Console(host=console_ip, port=console_port, key=console_key)
s = Statistics(console=c)

stats = s.get_jsonstats()
print(stats)
