Hi all, I'm wondering if someone else is running into the same problem of using temporary addresses under Debian 9.1.
I upgraded my Rasbian box to the latest Debian version (2017-08-16-raspbian-stretch-lite.zip) which is 9.1. $ cat /etc/debian_version 9.1 I changed the network configuration to static IPv4 and IPv6 with autoconfiguration and the use of temporary addresses: $ cat /etc/network/interfaces # interfaces(5) file used by ifup(8) and ifdown(8) # Please note that this file is written to be used with dhcpcd # For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf' auto enxb827ebb0d7c8 iface enxb827ebb0d7c8 inet static <removed part> iface enxb827ebb0d7c8 inet6 auto privext 2 Additionally use_tempaddr = 2 is configured in /etc/sysctl.conf for "all" and "default". (I know that the default for the network configuration is now to use dhcpcd. And of course this is what I used at the very beginning. But I saw the same problems with temporrary addresses, so I thought that it could be a problem of dhcpcd and tried to moved it out of the network config process.) After a reboot, the ethernet interface have a eui-64 based permanent ipv6 address (which was expected) but without any temporary address! This is different to previos Linux version. However the first temporary address is generated after the next router advertisment message comes in, so all seems to be fine. But after two or three days, the generation of new temporary addresses stopps! Now I'm stucked with two deprecated temporary addresses plus the eui64 based on on my interface. $ ip -6 addr show label "en*" scope global | sed "s/scope global//" 2: enxb827ebb0d7c8: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 state UP qlen 1000 inet6 <prfx>:2126:4424:3613:8eed/64 temporary deprecated dynamic valid_lft 7120sec preferred_lft 0sec inet6 <prfx>:d5d:bc76:397d:5d6c/64 temporary deprecated dynamic valid_lft 7120sec preferred_lft 0sec inet6 <prfx>:ba27:ebff:feb0:d7c8/64 mngtmpaddr dynamic valid_lft 7120sec preferred_lft 3520sec I've never seen this behavior before. Has anyone here an idea what's going wrong with my config or with Debian Unix? Has anyone a working config with temporary addresses on newer Debian Linux? Best regards Holger
