Dear Maintainer,

Whilst fail2ban builds successfully on unstable/amd64, according to
Debian Policy 4.9 packages may not attempt network access during
a build.

The full build log (including tcpdump output) is attached.


Regards,

We'll need at least:

There is also some log parsing code that is accessing the internet
too ("failed.dns.ch") but I'm finding it harder to find all the sources
of that.
