[aprssig] Web page index?

As you suggest, it's a security risk unless very carefully controlled and
understood. The NWS directories you mention are an example of this control
(there are some UK weather sat servers set up in a very similar way), in
that only specific information is in the folder.

If you can browse the raw website script files, you can often get database
passwords and other internal information, which is highly undesirable for
obvious reasons.

I think it is rare to see it enabled on an entire server. However it is
often used, and is not a security risk, for individual directories,
particularly those whose contents change dynamically. For example, the NWS
radar directories where each file name includes a timestamp is shown this
way. This is easily done with a file ".htaccess" for Apache web servers.

Bob, if you are hosted on an Apache web server (by far the most common) try
creating a file .htaccess in the directory you want to show, in the file put
the line

Options +Indexes

There are a couple different ways to show the index, depending on the server
default you can add either of these to get the non-default

IndexOptions +FancyIndexing

IndexOptions -FancyIndexing

if you have files you don't want to show, like jpgs and gifs for example,
you can use this line to exclude them from the listing

IndexIgnore *.gif *.jpg
