I am trying to audit2allow on F10 to allow a cgi-bin perl script to run

I bought the O'Reilly SE Linux book and learned the basics but it does

really seem to help me on Fedora.
there was no /var/log/kernel so I tried /var/log/secure with the
following
command sequence
setenforce 0
# access the cgi from the web
setenforce 1
audit2allow -l -i /var/log/secure
What is strange also is the system is not flagging things up as a
notification icon anymore in enforcing mode.
If someone could guide me or push me in the right direction I would be
most
thankful.
auditd logs to /var/log/audit/audit.log
To use cgi you must set the boolean httpd_enable_cgi.
Great GIT on Apache running now !:) Thanks
But not accessing the repositories, looks like a script is needed.
Then either label the cgi type httpd_sys_script_exec_t or create a
custom domain for your script:
mkdir myscript; cd myscript;
echo "policy_module(myscript, 0.0.1)" > myscript.te
echo "apache_content_template(myscript)" >> myscript.te
echo "/var/www/cgi-bin/myscript.pl --
gen_context(system_u:object_r:httpd_myscript_script_exec_t, s0)" >
myscript.fc
make -f /usr/share/selinux/devel/Makefile
semodule -i myscript.pp
restorecon -R -v /var/www/cgi-bin/myscript.pl
This is interesting. command line, thanks, interesting I will have to learn
this stuff on the command line to understand it properly.
This is just a base module you will likely need to extend it. you can do
so why making the httpd_myscript_script_t permissive and then extend
your source policy with any rules required frpm audit.log/audit2why
semanage permissive -a httpd_myscript_script_t
Nice :)
ausearch -m avc -ts today | grep httpd_myscript_script_t | audit2allow
-R >> myscript.te; make -f /usr/share/selinux/devel/Makefile; semodule
-i myscript.pp
This might just do the job !
semanage permissive -d httpd_myscript_script_t
(to remove the permissive domain)
Is there any reason not to be using setenforce 0/1, on a machine behind
firewall.
I will try this. Looks like theres a need of a good howto that shows how
simple these things can be.
Many thanks Dominick
Aaron
