Red Hat Bugzilla – Bug 239085
openvpn up script prevented from running by selinux targetted policy
Last modified: 2008-05-06 21:39:42 EDT
Description of problem: using Fedora 7 Test 4. I am using OpenVPN and my client.conf script has the following command in it: up /etc/openvpn/clientup.sh SELinux disallows running the script, generating the info atteched below. Should this be allowed through a boolean in the SELinux management tool? --------- Summary SELinux is preventing sh (openvpn_t) "execute" to clientup.sh (openvpn_etc_t). Detailed Description SELinux denied access requested by sh. It is not expected that this access is required by sh and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. Allowing Access Sometimes labeling problems can cause SELinux denials. You could try to restore the default system file context for clientup.sh, restorecon -v clientup.sh If this does not work, there is currently no automatic way to allow this access. Instead, you can generate a local policy module to allow this access - see http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385 Or you can disable SELinux protection altogether. Disabling SELinux protection is not recommended. Please file a http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this package.
