Source: radvd Version: 1:2.15-2 Severity: important I have no idea why, but I need to do /etc/init.d/radvd restart every few hours to keep everything working on my network correctly.
I have static IPv6 prefix. # cat /etc/radvd.conf interface enp2s0 { AdvSendAdvert on; MaxRtrAdvInterval 30; AdvDefaultPreference high; AdvManagedFlag off; AdvOtherConfigFlag off; AdvLinkMTU 1472; prefix 2a02:xxx:yyyy::/64 { AdvOnLink on; AdvAutonomous on; DeprecatePrefix on; DecrementLifetimes on; }; }; # -- System Information: Debian Release: buster/sid APT prefers unstable APT policy: (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.15.0-1-amd64 (SMP w/12 CPU cores) Locale: LANG=pl_PL.utf8, LC_CTYPE=pl_PL.utf8 (charmap=UTF-8), LANGUAGE=pl_PL.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled
