jo<p>Okay, really scary systemd-networkd moment: I replaced a lot of the <a href="https://chaos.social/tags/networkd" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>networkd</span></a> config files on my server with new ones, that create bonds, bridges, etc and even move the IP address I am connected to from one of the interfaces to a bridge and move the interface onto the bridge.</p><p>I prepared the OOB connection and entered `networkctl reload` with the expectation that I will break my config.</p><p>And 2 seconds later my prompt appeared again on my SSH session. I love it when stuff magically just works.😍</p>

NetworkManager<p><span class="h-card" translate="no"><a href="https://infosec.exchange/@alexhaydock" class="u-url mention">@<span>alexhaydock</span></a></span> my intent is to educate myself about CLAT and solicit more input on how reasonable is it to do the translation with a bpf program within NM? What are your (anybody reading this) thoughts on it?</p><p>What about those using <a href="https://fosstodon.org/tags/systemd" class="mention hashtag" rel="tag">#<span>systemd</span></a>-<a href="https://fosstodon.org/tags/networkd" class="mention hashtag" rel="tag">#<span>networkd</span></a> or <a href="https://fosstodon.org/tags/connman" class="mention hashtag" rel="tag">#<span>connman</span></a>? How does this compare to doing CLAT within userspace (via tunnel interface) or the kernel? Does CLAT really matter in GNU/Linux where the userspace is generally in better shape than Mac/Windows and we can just rebuild it?</p><p>[2/2]</p>
Andrew Helwer<p>Seems this is a bug in systemd-networkd unfortunately. So for now I just have to run dhclient after every suspend. <a href="https://bbs.archlinux.org/viewtopic.php?pid=2221138" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">bbs.archlinux.org/viewtopic.ph</span><span class="invisible">p?pid=2221138</span></a></p><p><a href="https://discuss.systems/tags/ArchLinux" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ArchLinux</span></a> <a href="https://discuss.systems/tags/Networkd" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Networkd</span></a></p>
Forst<p>I just hope the rest of the road is smoother.

Otherwise, newer versions of <a href="https://mstdn.social/tags/systemd" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>systemd</span></a> may adopt an incorrect MTU set by RA advertisements.
