Step 3 World Access

The world (other) needs read access to your home directory

This is done using chmod command


chmod a+rx ~


chmod 711 ~

All html files need to be readable by the world

Use:


chmod a+r filename

All cgi programs must:

End in .cgi
be world readable and executable

The latter can be done via:


chmod a+rx filename.cgi
