Previously, it was hosted on Ionos’s VMware-based infrastructure. I
already had a VPS on their new KVM-based infrastructure, as I was
planning to migrate okarin to it eventually (as it is cheaper). However,
the new infrastructure does not offer PTR records for IPv6 addresses.
Therefore, I was waiting until they would implement that feature (as the
support promised me they would to in the near future).
However, they are now migrating the (at least my) guests from their
VMware hypervisors onto the KVM ones, assigning new IPv6 addresses to
them. This makes the old VPS essentially the same as the old one, but
with less memory and more expensive. So I decided to migrate now.
It currently fails (logging an error message on every scrape). This
disables the netlink collector, making it fall back to reading ARP
entries from /proc/net/arp.
I am no longer willing to accept hours upon hours of debugging just to
get the client to work. I don’t get why they would ship a 32-bit GTK2
executable that uses CEF with its sandbox disabled in 2024. Obviously,
this makes debugging quite hard as things don’t work well, even when
they work. This leaves red herrings everywhere (“Is this segfault a
symptom of the issue I’m facing or is that also happening to other users
where it works fine?”).
Flatpak also seems to have quite good sandboxing features when Flatseal
is used for every application to take away any unnecessary permissions.
This still allows requesting a DSN over submission, so trusted clients
are not affected. It only affects sending DSN to other systems, which
now no longer takes place. This is done to avoid leaking rspamd
internals.
The previous implementation was copy-pasted from a source that did not
allow redistribution or sublicensing. Therefore, I reimplemented the
function myself.
