This happens with dhcpcd 3.2.3-87.1 It does not happen everytime. For me it has happened twice in one week now. The following happens in /var/log/messages: Nov 16 19:39:19 linuxhpd dhcpcd[23254]: eth1: lost lease Nov 16 19:39:19 linuxhpd dhcpcd[23254]: eth1: trying to use old lease in `/var/lib/dhcpcd/dhcpcd-eth1.info' Nov 16 19:39:19 linuxhpd dhcpcd[23254]: eth1: lease expired 53575 seconds ago Nov 16 19:39:19 linuxhpd dhcpcd[23254]: eth1: broadcasting for a lease Nov 16 19:39:19 linuxhpd dhcpcd[23254]: eth1: offered 85.229.132.208 from 85.229.128.1 Nov 16 19:39:39 linuxhpd dhcpcd[23254]: eth1: lost lease Nov 16 19:39:39 linuxhpd dhcpcd[23254]: eth1: trying to use old lease in `/var/lib/dhcpcd/dhcpcd-eth1.info' Nov 16 19:39:39 linuxhpd dhcpcd[23254]: eth1: lease expired 53595 seconds ago Nov 16 19:39:39 linuxhpd dhcpcd[23254]: eth1: broadcasting for a lease Nov 16 19:39:39 linuxhpd dhcpcd[23254]: eth1: offered 85.229.132.209 from 85.229.128.1 Nov 16 19:39:59 linuxhpd dhcpcd[23254]: eth1: lost lease .. And then it continues like that forever. If I do an ifdown eth1 and then ifup eth1 the lease is accepted again. I have logged the behaviour with wireshark and attach those logs for you to look at.

I have: DHCPCD_USER_OPTIONS="-p" default is: DHCPCD_USER_OPTIONS="" I have changed it to the default now and will report if the behaviour changes. I guess I will have to try it out for at least a week or two to be sure. I seem to recall that the reason I changed that option was when I had trouble with cifs shares disappearing when dhcp leases were renewed, see bug https://bugzilla.novell.com/show_bug.cgi?id=573246 -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

As you can see in the log below, the lease is renewed every 30 minutes except after 04:13. There is no renew at 04:43 even though there should be. So when we get to 05:16 where the next renew attempt is, the lease is already lost and I get a new IP address. Removing the -p option seems to have fixed the endless loop of failing to get a new IP though. The remaining problem now is that dhcpcd did not try to renew the address until after the lease had already expired, so I did not get to keep my IP.
