Re: Allowing httpd to connect to specific sockets

[Ian Lists <ian-list securitypimp com>]

This howto is exactly what I have been looking for.  I am trying to allow apache to connect to a listening stunnel process at localhost:9002. I think I have created mystunnel.te correctly, but I keep getting errors when I try to run the make against it.  

Here are the steps I have take so far.


# cat > mystunnel.te << _EOF
policy_module(mystunnel,1.0.0)

gen_require(\`
    type httpd_t;
')

type stunnel_port_t;
corenet_port(stunnel_port_t)

allow httpd_t stunnel_port_t:tcp_socket name_connect;
_EOF

# make -f/usr/share/selinux/devel/Makefile
Compiling targeted mystunnel module
/usr/bin/checkmodule:  loading policy configuration from tmp/mystunnel.tmp
mystunnel.te:8:ERROR 'syntax error' at token 'corenet_port' on line 77035:
type stunnel_port_t;
corenet_port(stunnel_port_t)
/usr/bin/checkmodule:  error(s) encountered while parsing configuration
make: *** [tmp/mystunnel.mod] Error 1



Thanks,

Ian

Hope you don't mind but I answered in my blog.
