But, how does one go about securing a "tilde town".
That is, when you're letting random strangers have access to your machine with a fully operating shell, all of the Unix tool suite, and even programming languages, what's the threat level like?
Most security today is keeping people off the server in the first place, but here we're holding the door open for them.
Back in the day, I had a Netcom dial up shell account. So, I assume there's some way to secure a system where folks log in to a random machine and have their home directory NFS mounted. In the old days, there was NIS, but that's right out from what I can read. Replaced with LDAP I reckon.
Anyway, I appreciate that many of these communities are "Friendly", with several "don't do that" clauses in their guidelines, but that doesn't mean there's not room for stuff to be better secured.
Any write ups on this?
