Package: ifupdown Version: 0.7.54 Severity: normal Tags: ipv6 Dear Maintainer,
Since v4.3, dhclient can comply with RFC 4361 by using some extra options. They are described in the "man" page of dhclient or this webpage : https://deepthought.isc.org/article/AA-01091/0/ISC-DHCP-support-for-Standard- DDNS.html These options are : "-I", "-D" and "-df". Steps to reproduce ================== - have a network configuration as the following auto eth0 iface inet eth0 dhcp iface inet6 eth0 dhcp Result ====== - two "dhclient" processes missing these options dhclient -v -pf /run/dhclient.eth0.pid -lf /var/lib/dhcp/dhclient.eth0.leases eth0 dhclient -6 -pf /run/dhclient6.eth0.pid -lf /var/lib/dhcp/dhclient6.eth0.leases eth0 expected result =============== - two "dhclient" processes with correct options dhclient -v -pf /run/dhclient.eth0.pid -lf /var/lib/dhcp/dhclient.eth0.leases -I -D LLT -df /var/lib/dhcp/dhclient6.eth0.leases eth0 dhclient -6 -pf /run/dhclient6.eth0.pid -lf /var/lib/dhcp/dhclient6.eth0.leases -I -D LLT -df /var/lib/dhcp/dhclient.eth0.leases eth0 Please note that the "-df" option point to the lease file of the *other* client. These extra options may be activated with specific keyword in the network configuration, for example : auto eth0 iface inet eth0 dhcp-rfc4361 iface inet6 eth0 dhcp-rfc4361 Regards, Nicolas -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.1.0-2-amd64 (SMP w/4 CPU cores) Locale: LANG=fr_FR.UTF-8, LC_CTYPE=fr_FR.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages ifupdown depends on: ii adduser 3.113+nmu3 ii initscripts 2.88dsf-59.2 ii iproute2 4.1.1-1 ii libc6 2.19-19 ii lsb-base 9.20150826 Versions of packages ifupdown recommends: ii isc-dhcp-client [dhcp-client] 4.3.3-3 Versions of packages ifupdown suggests: pn ppp <none> pn rdnssd <none> -- no debconf information -- Ce message a ete verifie par MailScanner pour des virus ou des polluriels et rien de suspect n'a ete trouve.
