Hi @netblue30,

the new 0.9.68-rc1 installs the file /etc/firejail/hostnames.
Is this file really supposed to be a configuration file? I.e. is the user supposed to change it?

The geoip-database package has its data for example in /usr/share/GeoIP/GeoIP.dat, which is probably a better place for static data.

I also think hostnames is a bit poorly named. I couldn't find any hostnames in the file, only mappings from IP addresses/ranges to their owners.

In a comment in this file you mention that you obtained it from a geoip package available on Linux distributions. I couldn't find such a file in the source of Debian's geoip-database.
(https://sources.debian.org/src/geoip-database/20191224-3/)
Can you please clarify what the source of the file is? I need to document its license etc in the package.

Bad name: I'll change it to static-ip-map.
I'll move the file to /usr/lib/firejail.

The file was build mainly by running /usr/bin/whois on addresses I saw coming up in the trace. Most webpages are served today from a handful of CDN or cloud providers. For Google, Cloudflare and Amazon I've found the official public webpages where they list their current addresses. We will have to update our list from time to time (I included the official webpages in the file).

The country name is printed in the trace only if geoip-bin is installed on the system. Our program calls /usr/bin/geoiplookup directly.

I'll put the fixes in, thanks.

Later: We are similar to geoip, all the data is compiled from public sources. I saw they use OpenDataLicense for copyright purposes. Probably we can stay with GPLv2.

I think that the license discussion probably deserves its own issue, so I
started one on #4888.

Closing this as the naming and path issues were fixed.
