Hmmm. But if I am another user on this box, I can set up a cgi script to update this data, because my cgi script is also run by the server as nobody. Yes?

If you have root access or a friendly sysadmin, ask them to install cgiwrap. Then you can run scripts as yourself, and set datafile permissions to 600. The cobalt RaQ servers come with cgiwrap seamlessly installed (not a plug, have had both good and bad experiences with these).

Alternatively, you can set the effective uid of the script with chmod u+s (I'm sure there are tutorials - I'm a little fuzzy on this as I use cgiwrap). Or write a C wrapper for the script and suid that (more robust for scripts that use system or backticks I think - but again, I'm not sure about this either, so look around).

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
