Hi

Can anyone please tell me, why every time codesys boots on the PLC, it rewrites the /etc/resolv.conf file.

Regards

Are you sure that it's Codesys and not some daemon like dhcpcd or NetworkManager?

  Well if I power cycle the PLC, it gets rewritten... so im not sure what rewrites it everytime. is there a way to determine what is doing it?

  I know on the pi-based systems you need to be editing /etc/dhcpcd.conf to configure the network correctly.
  
  Editing resolv.conf manually and trying to keep it from changing is not worth the hassle anymore. I do miss it though.
