I was asked to post this information here. To explain things,
I have installed FrontPage extensions on FC4
,,,
From Paul Howarth, I tried:
=============================================
If you want httpd to be able to listen on port 8090, and you have the
policy sources installed, you can do this by adding the following line
to /etc/selinux/targeted/src/policy/net_contexts:
portcon tcp 8090 system_u:object_r:http_port_t
Then you need to compile and reload the security contexts:
# make -C /etc/selinux/targeted/src/policy reload
=============================================
This all compiles fine now.
Testing to see if httpd can now restart with the new policies:
1) setsebool -P httpd_disable_trans 0
2) Restart httpd for this to take effect: service httpd restart
Httpd can restart with no failure messages. The httpd server
now runs fine.
HOWEVER - Testing FrontPage client against my FC4 box FAILS to
connect and the reason revealed in /var/log/httpd/error_log:
[Tue Nov 08 15:25:40 2005] [error] (13)Permission denied: Could not create key file "/usr/local/frontpage/version5.0/apache-fp/suidkey.17096" in FrontPageInit(). Until this problem is fixed, the FrontPage security patch is disabled and the FrontPage extensions may not work correctly.
I suspect that there is a SElinux policy that is preventing the FP
client program from creating and deleting the suidkey file it needs
in order to startup and begin listening for FP Client requests. Please
note that the process number is created and destroyed for the suidkey file
and this is happening from within the httpd service file and has nothing
to do with the FP client connection attempts. SELinux policy is preventing
the service file from creating and destroying this file.
There is no SELinux policy defined for anything under /usr/local, since
it is entirely down to the user what goes in there. If you want Fedora's
httpd to work with SELinux and CGI programs under /usr/local, you will
need to set the file contexts appropriately yourself.
Without seeing the actual AVC messages you're getting, it's hard to say
what the contexts should be. However, a useful guide to SELinux and
httpd can be found at:
http://fedora.redhat.com/docs/selinux-apache-fc3/
In the section on customising policy, the document assumes you're
running the "strict" policy, so you'll probably need to change "strict"
to "targeted" wherever it occurs.
