Prevent logging of sensitive info

[Juul]

The nodes are logging which clients associate and disassociate + IP leases offered.

We want to enable this for debugging purposes but it should be default off. Perhaps completely disabling logging is a good idea or perhaps we can filter sensitive information

@Juul As I mentioned after last meeting -- but not exactly what I remembered, and perhaps not as relevant: https://github.com/EFForg/cryptolog

status update?

Logging is still enabled, https://github.com/sudomesh/sudowrt-firmware/blob/master/files/etc/config/system, I suggest commenting it out and then including a script that can be run on the node to uncomment the relevant lines.
