Package: network-manager Version: 1.30.0-2 tags: ipv6 I'm running a Debian system on a LAN segment configured to assign IPv6 addresses via SLAAC. After upgrading from Buster to Bullseye, NetworkManager starts the system with an IPv6 stable-privacy address as usual. However, after some time (possibly during address renewal), a standard EUI-64 address with the "mngtmpaddr" flag is created in addition and this address takes precedence (i.e. new connections originate from this EUI-64 address).
The sysctl values for this are, I assume, default, as I have not changed them: $ sudo sysctl -a | grep use_tempaddr net.ipv6.conf.all.use_tempaddr = 0 net.ipv6.conf.default.use_tempaddr = 0 net.ipv6.conf.eno1.use_tempaddr = 0 net.ipv6.conf.lo.use_tempaddr = -1 As is NetworkManager's config: $ nmcli conn show "Ifupdown (eno1)" | grep addr-gen-mode ipv6.addr-gen-mode: stable-privacy Restarting the NetworkManager service and bringing the interface down, then up, resets everything back to the expected stable-privacy addresses. In case it could be relevant, the Ethernet controller being used on this system is an Intel I219-V. The latest point release kernel as of this writing (5.10.0-9-amd64/5.10.70-1) is also being used. _______________________________________________ Pkg-utopia-maintainers mailing list [email protected] https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/pkg-utopia-maintainers
