Windows: Rotating the log file

[George Thessalonikefs]

Hi RayG,

My colleague Wouter suggested the following and I believe it will work 
on Windows (haven't tested; not a windows user):

1.
`unbound-control.exe set_option logfile: unbound-2.log`
this will change the value for the logfile in the unbound *running* 
configuration.

2.
`unbound-control.exe log_reopen`
this tells unbound to end the old logfile and switch logging to 
unbound-2.log and then starts writing to the new file.

This is of course not automated and not configurable but you can script 
it and rotate however you want.

Note that during 1 above I would also change the value in the 
configuration file itself so that the last logfile value is saved for a 
restart.

Hope that helps.

Best regards,
-- George

At this point in time it would appear to be the event log which is not what I was expecting use_syslog I would have expected it to go to the local system UDP/TCP on port 514 but that does not seem to be happening.
