Hi Stefan, thanks for your input ... maybe I've forgot to mention that it could be also considered as a regression because in past no such a timer that was periodically refreshing/enforcing policy was in NM .. I've run into this issue after recently upgrading from 15.1 (yep, please forgive me :D) at current 15.6 .. This is clearly new behaviour to see in journal stream of messages like this Oct 02 14:54:50 linux-1b6m NetworkManager[1878]: <info> [1727873690.9813] policy: set 'Pecka' (wlan0) as default for IPv6 routing and DNS Oct 02 15:24:51 linux-1b6m NetworkManager[1878]: <info> [1727875491.0779] policy: set 'Pecka' (wlan0) as default for IPv6 routing and DNS Oct 02 15:54:51 linux-1b6m NetworkManager[1878]: <info> [1727877291.2020] policy: set 'Pecka' (wlan0) as default for IPv6 routing and DNS Oct 02 16:24:51 linux-1b6m NetworkManager[1878]: <info> [1727879091.5914] policy: set 'Pecka' (wlan0) as default for IPv6 routing and DNS Oct 02 16:54:51 linux-1b6m NetworkManager[1878]: <info> [1727880891.4609] policy: set 'Pecka' (wlan0) as default for IPv6 routing and DNS Oct 02 17:24:51 linux-1b6m NetworkManager[1878]: <info> [1727882691.7657] policy: set 'Pecka' (wlan0) as default for IPv6 routing and DNS Oct 02 20:54:00 linux-1b6m NetworkManager[1878]: <info> [1727895240.4170] policy: set 'Pecka' (wlan0) as default for IPv4 routing and DNS Oct 02 20:54:04 linux-1b6m NetworkManager[1878]: <info> [1727895244.0664] policy: set 'Pecka' (wlan0) as default for IPv6 routing and DNS Oct 02 20:54:52 linux-1b6m NetworkManager[1878]: <info> [1727895292.8249] policy: set 'Pecka' (wlan0) as default for IPv6 routing and DNS Oct 02 21:24:52 linux-1b6m NetworkManager[1878]: <info> [1727897092.7127] policy: set 'Pecka' (wlan0) as default for IPv6 routing and DNS Oct 02 21:54:52 linux-1b6m NetworkManager[1878]: <info> [1727898892.9391] policy: set 'Pecka' (wlan0) as default for IPv6 routing and DNS Oct 02 22:24:53 linux-1b6m NetworkManager[1878]: <info> [1727900693.0543] policy: set 'Pecka' (wlan0) as default for IPv6 routing and DNS Oct 02 22:54:53 linux-1b6m NetworkManager[1878]: <info> [1727902493.1649] policy: set 'Pecka' (wlan0) as default for IPv6 routing and DNS Oct 02 23:24:53 linux-1b6m NetworkManager[1878]: <info> [1727904293.5259] policy: set 'Pecka' (wlan0) as default for IPv6 routing and DNS Oct 02 23:54:53 linux-1b6m NetworkManager[1878]: <info> [1727906093.4778] policy: set 'Pecka' (wlan0) as default for IPv6 routing and DNS Oct 03 00:24:53 linux-1b6m NetworkManager[1878]: <info> [1727907893.5797] policy: set 'Pecka' (wlan0) as default for IPv6 routing and DNS Oct 03 08:34:49 linux-1b6m NetworkManager[1878]: <info> [1727937289.9427] policy: set 'Pecka' (wlan0) as default for IPv4 routing and DNS Oct 03 08:34:51 linux-1b6m NetworkManager[1878]: <info> [1727937291.4157] policy: set 'Pecka' (wlan0) as default for IPv6 routing and DNS or perhaps maybe it was there before but NM was not updating (or to be precise `restoring') /etc/resolv.conf every thirty minutes if the resolv.conf was governed by other application (like for instance standalone vpn client) .. regards, ~dan
