TomHey <a href="https://mastodon.bsd.cafe/tags/BSD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BSD</a> friends! Is there a way to set up oauth2 on Dovecot for authentication? (All local Auth, no Google or Microsoft involved). Do I have to run some big chunky java blob like keycloak or is there a much lighter weight implementation in C somewhere? <a href="https://mastodon.bsd.cafe/tags/OpenBSD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#OpenBSD</a> <a href="https://mastodon.bsd.cafe/tags/dovecot" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#dovecot</a> <a href="https://mastodon.bsd.cafe/tags/opensmtpd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#opensmtpd</a> <a href="https://mastodon.bsd.cafe/tags/oauth2" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#oauth2</a>

Stuart Longland (VK4MSL)Well, after a lot of swearing… I *think* I have a Raspberry Pi 400 running <a href="https://aus.social/tags/AlpineLinux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#AlpineLinux</a> … tethered to my 4G phone hotspot … acting as a crude WiFi router/bridge for my border router running <a href="https://aus.social/tags/OpenBSD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#OpenBSD</a> which is tunnelling to my OpenBSD VPS at Binary Lane.Over that tunnel, I now have <a href="https://aus.social/tags/Postfix" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Postfix</a> on the home mail server, relaying over the VPN to <a href="https://aus.social/tags/OpenSMTPD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#OpenSMTPD</a> on the VPS.Should be useful the day I have to leave Internode… but for now, it's bypassing the rather dead NBN service (thank-you <a href="https://aus.social/tags/CycloneAlfred" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CycloneAlfred</a>).

kuijstenI've released an SPF filter for OpenSMTPD: <a class="mention u-url" href="https://netsend.nl/opensmtpd-filter-spf/" rel="nofollow noopener noreferrer" target="_blank">https://netsend.nl/opensmtpd-filter-spf/</a> <a class="mention u-url" href="https://honk.netsend.nl/o/opensmtpd" rel="nofollow noopener noreferrer" target="_blank">#opensmtpd</a> <a class="mention u-url" href="https://honk.netsend.nl/o/milter" rel="nofollow noopener noreferrer" target="_blank">#milter</a> <a class="mention u-url" href="https://honk.netsend.nl/o/spf" rel="nofollow noopener noreferrer" target="_blank">#spf</a>

Stefano MarinelliGood morning, friends of the <a href="https://mastodon.bsd.cafe/tags/BSDcafe" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BSDcafe</a> and <a href="https://mastodon.bsd.cafe/tags/fediverse" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#fediverse</a> I'd like to share some details on the infrastructure of BSD.cafe with you all. Currently, it's quite simple (we're not many and the load isn't high), but I've structured it to be scalable. It's based on <a href="https://mastodon.bsd.cafe/tags/FreeBSD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FreeBSD</a>, connected in both ipv4 and ipv6, and split into jails:* A dedicated jail with nginx acting as a reverse proxy - managing certificates and directing traffic * A jail with a small <a href="https://mastodon.bsd.cafe/tags/opensmtpd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#opensmtpd</a> server - handling email dispatch - didn't want to rely on external services * A jail with <a href="https://mastodon.bsd.cafe/tags/redis" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#redis</a> - the heart of the communication between <a href="https://mastodon.bsd.cafe/tags/Mastodon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Mastodon</a> services - the nervous system of BSDcafe * A jail with <a href="https://mastodon.bsd.cafe/tags/postgresql" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#postgresql</a> - the database, the memory of BSDcafe * A jail for media storage. The 'multimedia memory' of BSDcafe. This jail is on an external server with rotating disks, behind <a href="https://mastodon.bsd.cafe/tags/cloudflare" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cloudflare</a>. Aim is georeplicated caching of multimedia data to reduce bandwidth usage. * A jail with Mastodon itself - <a href="https://mastodon.bsd.cafe/tags/sidekiq" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sidekiq</a>, <a href="https://mastodon.bsd.cafe/tags/puma" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#puma</a>, <a href="https://mastodon.bsd.cafe/tags/streaming" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#streaming</a>. Here is where all processing and connection management takes place.All communicate through a private LAN (in bridge) and is set up for VPN connection to external machines - in case I want to move some services, replicate or add them. The VPN connection can occur via <a href="https://mastodon.bsd.cafe/tags/zerotier" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#zerotier</a> or <a href="https://mastodon.bsd.cafe/tags/wireguard" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#wireguard</a>, and I've also set up a bridge between machines through a <a href="https://mastodon.bsd.cafe/tags/vxlan" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#vxlan</a> interface over <a href="https://mastodon.bsd.cafe/tags/wireguard" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#wireguard</a>.Backups are constantly done via <a href="https://mastodon.bsd.cafe/tags/zfs" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#zfs</a> snapshots and external replication on two different machines, in two different datacenters (and different from the production VPS datacenter).<a href="https://mastodon.bsd.cafe/tags/sysadmin" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sysadmin</a> <a href="https://mastodon.bsd.cafe/tags/tech" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#tech</a> <a href="https://mastodon.bsd.cafe/tags/servers" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#servers</a> <a href="https://mastodon.bsd.cafe/tags/ITinfrastructure" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ITinfrastructure</a> <a href="https://mastodon.bsd.cafe/tags/BSD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BSD</a>
