Question: DHCP requests? #214

Closed hspindel closed 10 months ago

hspindel commented 10 months ago

If I'm reading my logs right, piAlert is making frequent DHCP requests. The DHCP server makes an offer, which is not ACK'ed.

Is this expected behavior? What would disable it?

Thank you.

If the search for rogue DHCP servers is active, this is normal. If this is not desired, it can be switched off in the configuration file.

If the search is enabled, you see entries like this in the scan log
