The college I'm attending provides accounts on a SunOS server for students taking technical-type classes (programming, web design, etc). I was trying to find where the sysadmin had buried Apache's log files one night when I noticed find
was returning some odd errors. I didn't have read permissions for several directories that I thought I should be able to access.

That seemed odd, yet familiar... I double-checked:
<font face="Courier New">superhost-james% cat /etc/passwd | grep :755:
superhost-james%</font>
Sure enough, no 755 user.
