https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D218980 Bug ID: 218980 Summary: dhclient incorrectly handles very long lease times, setting expiry in the past Product: Base System Version: 11.0-STABLE Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: bin Assignee: freebsd-bugs@FreeBSD.org Reporter: bob@eager.cx Created attachment 182197 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D182197&action= =3Dedit Contents of typical dhclient.leases.INTERFACE file If the DHCP server is set to hand out a long lease time (effectively infini= te) then dhclient calculates an expiry time (and a renew time) in the past. Repeat-by: 1) set DHCP server to hand out a lease of (say) 2147483600 2) boot a relevant client running latest dhclient Observed: DHCP server assigns an IP address, and dhclient gets it. It doesn= 't appear on the interface, and dhclient tries continually to get another one (look in /var/log/messages). Also observed: /var/db/dhclient.leases.$INTERFACE contains a valid rebind d= ate, but invalid renew and expire dates, in the past. It appears that any assigned address is immediately expired! --=20 You are receiving this mail because: You are the assignee for the bug.=
