I don't know if this is an easy one to answer, but I have a VPS and I have noticed a while back that all files created can be read by other users (because files are +r for "others", for some reason).
Why is it like this? I'm using Ubuntu Server edition, is it only like that on Ubuntu?
I think it doesn't respect users' privacy...
Is there a good reason to keep it that way?
If not, how can I change it so all files created by a user in its home folder, for example, is not readable by others?
