I think the ISC dhclient (which is what I use here) does try to return to its original server. Rather than reboot anything, I simply stopped the DHCP server on that machine. Apparently clients then started back at the beginning. Shortening the lease time accelerates that process. -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/
