Jul 23, 2025, 7:00 PMCrap, during some IPv6 mishaps in my home network, I somehow disabled the sysctl paramter 'accept_ra' for my primary interface under Debian Sid and I have no clue how, nothing in /etc/sysctl.d and /etc/sysctl.conf doesn't exist because systemd, my shell history has already rotated way past whenever I messed with that parameter and it's neither a kernel command line parameter, nor does grep on the entire filesystem give anything useful back. Oh no :neocat_googly_shocked:
Jul 23, 2025, 7:09 PM@snep can you just set it to 1 again in sydsctl.conf(.d)?
Jul 23, 2025, 7:22 PM@uvok Yeeeh, that's what I went with for now, a full, fresh install is in order sometime soon anyways, so this works as a slightly bodged fix for now :neocat_laugh_sweat:
@snep if you're using systemd-networkd, check the IPv6AcceptRA setting in the interface's .network file, see systemd.network(5)
Jul 23, 2025, 7:20 PM@woelfisch Thank you for the hint! Though I'm on NetworkManager, which doesn't seem to have anything special configured in this regard. I just added a custom sysctl.d configuration which re-enables 'accept_ra' for my interface - Good enough since I plan on doing a fresh install at the latest when Debian Trixie gets released, even if a bit hacky :neocat_laugh_sweat:
