Besides the other comments I'd use tcpdump to see if there was any response from the DHCP server.
In addition configuring the interface using the IP address assigned by DHCP is a really bad idea. Someday that address could get assigned to a different system, this will most occur when you least expect it. Fixing a problem is always better than a bandaid solution. diana On May 27, 2024 8:38:42 AM MDT, Souji Thenria <m...@souji-thenria.net> wrote: >On Mon May 27, 2024 at 1:51 PM BST, Chris Narkiewicz wrote: >> I have a netcup VPS and it crashed recently.
