Public bug reported: Package: dhcpcd5 Version: 6.11.5-0ubuntu1 Release: artful
dhcpcd5 in artful is outputting repeated messages about adding/deleting ipv6 default routes. I didn't check other releases. The actual log is not the problem, but the actual behavior seems to be: I don't expect dhcpcd to be adding a default route only to then instantly remove it. The only similar issue I could find was this one: https://serverfault.com/questions/846019/dhcpcd-ipv6-excessive-adding-removing-route-in-log but the solution presented there (removing the route manually) does not work on this case. I found nothing in dhcpcd bug tracking tool at https://dev.marples.name/maniphest/query/all/ Copy & paste from syslog: Jun 7 17:10:18 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:10:18 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 Jun 7 17:10:23 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:10:23 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 Jun 7 17:10:29 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:10:29 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 Jun 7 17:10:36 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:10:36 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 Jun 7 17:10:43 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:10:43 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 Jun 7 17:10:49 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:10:49 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 Jun 7 17:10:56 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:10:56 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 Jun 7 17:11:02 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:11:02 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 Jun 7 17:11:08 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:11:08 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 Jun 7 17:11:15 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:11:15 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 Jun 7 17:11:19 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:11:19 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 Jun 7 17:11:22 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:11:22 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 Jun 7 17:11:26 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:11:26 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 Jun 7 17:11:33 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:11:33 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 Jun 7 17:11:38 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:11:38 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 Jun 7 17:11:48 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:11:48 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 Jun 7 17:11:56 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:11:56 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 Jun 7 17:12:05 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:12:05 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 Jun 7 17:12:14 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:12:14 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 Jun 7 17:12:17 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:12:17 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 Jun 7 17:12:27 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:12:27 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 Jun 7 17:12:34 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:12:34 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 Jun 7 17:12:37 localhost dhcpcd[1585]: wlan0: adding default route via fe80::1:1 Jun 7 17:12:37 localhost dhcpcd[1585]: wlan0: deleted default route via fe80::1:1 ====================== $ cat /etc/dhcpcd.conf # A sample configuration for dhcpcd. # See dhcpcd.conf(5) for details. # Allow users of this group to interact with dhcpcd via the control socket. #controlgroup wheel # Inform the DHCP server of our hostname for DDNS. hostname # Use the hardware address of the interface for the Client ID. #clientid # or # Use the same DUID + IAID as set in DHCPv6 for DHCPv4 ClientID as per RFC4361. # Some non-RFC compliant DHCP servers do not reply with this set. # In this case, comment out duid and enable clientid above. duid # Persist interface configuration when dhcpcd exits. persistent # Rapid commit support. # Safe to enable by default because it requires the equivalent option set # on the server to actually work. option rapid_commit # A list of options to request from the DHCP server. option domain_name_servers, domain_name, domain_search, host_name option classless_static_routes # Most distributions have NTP support. option ntp_servers # Respect the network MTU.
