[mapserver-users] Access control for wms served from mapserver cgi

[Robert Sanson]

Hi Marc
 
Where do you set this? Is it somewhere in httpd.conf?
 
Many thanks,
 
Robert Sanson

Hello,

We are using this very basic setting:

# Demo WMS
Alias /wms-demo/usr/lib/cgi-bin/mapserver
<Location /wms-demo>
  Deny from all
   #   My network
   Allow from  10.133
   SetHandler cgi-script
   Options ExecCGI
   SetEnv MS_MAPFILE /var/www/wms/wms-demo/wms-demo.map
</Location>

Cheers

Marc Monnerat

mapserver cgi

Hello Rahkonen (and Stephan),

This is an idea that I could make work...I'd have to lock-down mapserv

itself from all connections (otherwise anyone could just replace 
wms*.exe in the URL with the original mapserv.exe), though I guess I 
should be doing that anyway.

In response to Stephan Holl: I recognize there are other strategies
that 
involve proxying the WMS requests.  I was just hoping for something 
quick and easy that could be done with Apache more or less 
out-of-the-box using basic config files and/or modules like
mod_rewrite. 
  There have been a few cases where I needed to use mapserver on one 
machine to serve data using WMS to another server running mapserver as
a 
WMS client.  I just want to be able to do that with as little work as 
possible (i.e., if I can do it in Apache's config, then I can do it 
anywhere).

Essentially, my ideal solution would be if I can get something like 
mod_rewrite to say "if a request to mapserv contains 
'map=/path/to/somefile.map' in the query string, and the client is not

equal to some IP address, return 403, otherwise allow the request".  I

just don't quite know how to get mod_rewrite to work like that for me
(I 
found some promising examples online, but couldn't get them working).

Thanks again,
Mike
