Hi, I havea laptop running fully up to date Stretch with NetworkManager, set to use DH|Cp via wireless.
The DHCP server is another Stretch system, with the stanzas host tony-lt { hardware ethernet 0c:60:76:6c:e6:6f; fixed-address 192.168.1.199; } subnet 192.168.1.0 netmask 255.255.255.0 { range 192.168.1.200 192.168.1.254; option routers 192.168.1.10; } That MAC is correct for the laptop. I an expecting to see 192.168.1.199 as the laptop address, but no, if a gives: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 0c:60:76:6c:e6:6f brd ff:ff:ff:ff:ff:ff inet 192.168.1.253/24 brd 192.168.1.255 scope global dynamic wlan0 valid_lft 479sec preferred_lft 479sec Finally, the server shows: Oct 23 14:23:38 routerpi dhcpd[1068]: DHCPREQUEST for 192.168.1.253 from 0c:60:76:6c:e6:6f (tony-lt) via eth0 Oct 23 14:23:38 routerpi dhcpd[1068]: DHCPACK on 192.168.1.253 to 0c:60:76:6c:e6:6f (tony-lt) via eth0 Oct 23 14:23:53 routerpi dhcpd[1068]: reuse_lease: lease age 15 (secs) under 25% threshold, reply with unaltered, existing lease for 192.168.1.253 Oct 23 14:23:53 routerpi dhcpd[1068]: DHCPREQUEST for 192.168.1.253 from 0c:60:76:6c:e6:6f (tony-lt) via eth0 Oct 23 14:23:53 routerpi dhcpd[1068]: DHCPACK on 192.168.1.253 to 0c:60:76:6c:e6:6f (tony-lt) via eth0 So, my question: why is the server handing out .253, when it is configured to provide .199? What is this 'reuse-lease' all about? I've tried 'dhclient -r wlan 0; dhclient -v wlan0' on the laptop, to no avail. Any suggestions, please? -- Tony van der Hoff | mailto:t...@vanderhoff.org Ariège, France |
