the problem is they both have valid points. in this,as in nearly all aspects
of unix administration, there is not a single right answer.

First, I can't really understand why either one of you two won't fully
explain your reasonings when going against the other. It helps noone.

Of course, if you have a system with _no_ services running (including
apache, sshd and so on), or a firewall that blocks every and all
incoming connection attempt, then for someone to access /tmp without
having physical access to the system (in which case you're pretty much
screwed anyhow) is, as far as I know, impossible.=20
This doesn't take into account client-side exploits; because with these
the exploiting code has access to whatever resources the user running
the client has, including writing to whatever areas that the user has.=20
