Compile from source (when you need precisely 6.8.2): dhcpcd-6.8.2-armv7l
Requesting and renewing dynamic IP addresses from a DHCP server.
However, for specific embedded use-cases, you will need to modify this file. Below is a breakdown of common configurations, including a sample snippet from a real-world dhcpcd-6.8.2.conf file used in an Android system: # Run in foreground with debug output dhcpcd
