Thanks for the rapid response. Here's the information you're asking for:
I. What operating system are you running?
The Mandriva 10.2 (free version) release of Linux. (When it's time to
upgrade, I think we're going with something else. Suggestions welcome.)
II. Does the temporary directory actually exist after hardcopy runs?
What are its user, group, and permissions, and the user, group, and permissions of the enclosing directory?
Yes it exists. Its user and group are apache:wwdata. The web server is
running as user apache, group apache. User apache is a member of the
group wwdata (as verified by "id apache".)
Here's a directory listing from one of these directories (ls -l):
drwxr-sr-x 2 apache wwdata 4096 Jan 7 10:45 work.8wpO3NtB/
All ancestors in the directory tree up to (but not including) /opt are
owned by apache:wwdata and have permission drwxr-sr-x except for
/opt/webwork2, which has permission drwxrwsr-x.
III. Do you have any additional access control in use, such as ACLs or SELinux?
As near as I can tell, SELinux is not active. We haven't explicitly set
up ACLs either. The apache server we're using was compiled locally, not
the one from the distribution.
IV. If you log in as the web server user, are you able to delete it manually?
I can't think of other relevant information. Hardcopy generation worked
fine until the upgrade (modulo the timezone problem noted in a
Thanks for your help.
