Re: gnunet-rest-server shutdown issues

[Nikita Ronja Gillmann]

Hi,

so the issue still exists, but I didn't have the time to send more information,
busy last months.
I'll try to get back to you soon.

As an aside: I haven't followed gnunet development that much recently,
but as I have started to add invocations for a couple of BSDs to
gnunet-dns-helper (a long time ago and ran out of time as well), I was
wondering if those firewall parts would eventually become obsolete in
the rewrites you are doing right now, long-term?
