[mapserver-users] Trouble with MapServer cgi

[Leigh Holcombe]

Hello,
I've been trying to learn the MapServer software for a few weeks now.  Mostly, I've been running some examples from Bill Kropla's book, but I've also been trying out some things on my own.  I'm running version 5.6.5 on Fedora 13.

My first question is about SELinux context.  After yum installation, the mapserv executable found in /usr/sbin has a context of system_u:object_r:bin_t:s0.  However, this causes serious problems for SELinux.  After trying numerous modifications, I have found that unconfined_u:object_r:httpd_unconfined_script_exec_t:s0 works - however, according to documentation, this is just barely better than turning SELinux off.  Can you offer any advice about setting this properly?  While SELinux is not crucial to my practice development, I feel it's a good idea to learn it.

Secondly, I am having trouble loading map images without forms.  I have a properly configured virtual host, whose docroot is /var/www/html/nwss.dev.  My cgi directory is /var/www/cgi-bin, and my mapfile is located in /var/www/html/nwss.dev/mapserver_test.  According to the documentation, the path passed to the executable should be the path relative to the cgi location.  I take this to mean that either the absolute path above or the relative path ../html/nwss.dev/mapserver_test should work.  However, it does not.  Here is the HTML code I am trying to use (without < >):

img src="http://www.nwss.dev/cgi-bin/mapserv?map=../html/nwss.dev/mapserver_test/map_13.map?mode=map" width="800" height="800" border="0"

The web section (is it necessary in this example?) of my mapfile is:
WEB
	TEMPLATE "/var/www/html/nwss.dev/mapserver_test/map_13.html"
	IMAGEPATH "/var/www/html/nwss.dev/mapserver_test/tmp/"
	IMAGEURL "/mapserver_test/tmp/"
END #end web

Clearly, I'm doing something wrong.  But based on what I've read, it seems right.  Help!  Thanks for your time.
