[wplug] Breakin attempts against the nobody account

Sometime in March Bill Moran assaulted the keyboard and produced:

| My question is: Are there systems out there with an unsecured "nobody"
| account by default?  Or are there installation profiles that enable the
| "nobody" account?

On occasion I've been know to give nobody a shell. The reason that I do
this is that sometimes I run into permission problems (webserver not being
able to read files). The easiest way to check such things is to become the
web user and see if I can read the files. On Redhat this used to be nobody;
on the Debian it's www-data (at least it is for now). Now when I do this, I
set the nobody password to something nontrivial and I change the shell to
/bin/false when I'm done.

| I'm just curious, since I'm not familiar with any way this would ever
| work.

Perhaps other flavors of unix have this enabled by default?
