There's a bit of a mess with protocols/services in the latest builds
from IANA-ETC.
1) They require that Python-3 be installed, because you need to generate
these files in these latest releases by running a script 'update.py',
instead of just being given them in the release.
2) The Python-3 script has a bug in the use of an obsolete method name
that needs fixing.
3) The generated services/protocols files are set to permission 600
instead of the proper 644 - which is really annoying, because if these
permissions are retained (such as in an original copy to /etc, where the
files do not previously exist) - then programs that are not run as root
cannot read these files, which means that they get weird errors such as
'unknown protocol tcp' or 'unknown service this-or-that'. Determining
that the cause of these errors are too-strict permissions on the
protocols and services file is not the easiest thing in the world to do.
Net-net, here is the little script I wrote to handle this situation:
sed -i 's?getiterator?iter?g' update.py
python3 update.py out
cp -v out/dist/{protocols,services} /etc
chmod -v u+w,a+r /etc/{protocols,services}
ls -l /etc/{protocols,services}
