That's good to hear, thanks.

Yes, NIS is mentioned:
$ grep -i nis /etc/nsswitch.conf
netgroup: nis
But I can't make anything out of this. I guess I'll have to read
about portmapper to learn a bit about it -- at the moment, I'm
completely ignorant as I haven't had the need for it or anything.
Still, thanks for the help and your suggestions; the fact, that
nothing listens on port 111 makes me feel a little bit better, and
your sentence "there's no reason to be concerned" makes me feel even
better. :-) Of course, a Paranoid Android should still think, that
you belong to a secret group government has put up to extract
information of my daily use of it...
Thanks!
