Yesterday I noticed a warning my terminal window showed when I installed Samba. The warning was:
WARN: /etc/default/ufw is group writable!
WARN: /etc/default is group writable!
WARN: /etc is group writable!
WARN: / is group writable!

WARN: /etc/ufw/before.rules is group writable!
WARN: /usr/sbin/ufw is group writable!

I don't know how long this problem has been around (although I don't think it has been more than a few weeks at most), since I don't use the terminal very often. And I don't know what caused the shift in permissions.

My question is, what are normal values for permissions in these folders? Would it solve the problem if I removed the group write permissions through the chmod command? And are there any other things I should look out for?
Thanks!
