--- Begin Message ---Package: isc-dhcp-client Version: 4.3.1-5 Severity: normal Dear Maintainer, I have a dual-stack home network, with ip6 & ip4 addresses provided by dhcp from my router. However, by default I cannot get both interfaces to come up correctly My /etc/dhcp/dhclient.conf is option rfc3442-classless-static-routes code 121 = array of unsigned integer 8; interface "eth0" { send host-name = gethostname(); #append domain-name-servers 192.168.178.1; #append domain-name "fritz.box"; #append domain-search "fritz.box"; #append dhcp6.name-servers 2001:470:xxxxxx; # ip removed #append dhcp6.domain-search "fritz.box"; supersede domain-name-servers 192.168.178.1; supersede domain-name "fritz.box"; supersede domain-search "fritz.box"; supersede dhcp6.name-servers 2001:470:xxxxxx; # ip removed supersede dhcp6.domain-search "fritz.box"; request subnet-mask, broadcast-address, time-offset, routers, domain-name, domain-name-servers, domain-search, host-name, dhcp6.name-servers, dhcp6.domain-search, netbios-name-servers, netbios-scope, interface-mtu, rfc3442-classless-static-routes, ntp-servers; } in /etc/network/interfaces I have (currently) auto eth0 iface eth0 inet dhcp iface eth0 inet6 dhcp autoconf 1 In the order specified, the v4 and v6 addresses comes up fine, but the ipv6 dhcp overwrites /etc/resolv.conf (ignores the supersede lines) In the reverse order (ipv6 first) the v6 address comes up fine (apart from resolv.conf), but the v4 fails (manually running dhclient -v -4 gives "No broadcast interfaces found - exiting") The bugs are: 1. dhclient seems to be ignoring the supersede (and/or append) lines (at least for ipv6) 2. dhclient -4 fails when an interface is active with an ipv6 address 3. (my router sends the wrong nameserver for ipv6 - not the subject of this bug though) For now, I have added a hook in /etc/dhcp/dhclient-exit-hooks.d/ to recreate resolv.conf using the ipv4 nameservers.
