### 5.3 Debug levels

The tinc daemon can send a lot of messages to the syslog. The higher the debug level, the more messages it will log. Each level inherits all messages of the previous level:

‘`0`’

  This will log a message indicating tinc has started along with a version number. It will also log any serious error.

‘`1`’

  This will log all connections that are made with other tinc daemons.

‘`2`’

  This will log status and error messages from scripts and other tinc daemons.

‘`3`’

  This will log all requests that are exchanged with other tinc daemons. These include authentication, key exchange and connection list updates.

‘`4`’

  This will log a copy of everything received on the meta socket.

‘`5`’

  This will log all network traffic over the virtual private network.
