Description

2010-04-28 10:27:15 UTC
This is caused by executing ipsec auto --up rh-vpn Which does produce an error messages: 003 "rh-vpn" #3: updateresolvconf-client command exited with status 1 and /etc/resolv.conf isn't updated with the new nameserver After setenforce Permissive there is also the following alert: Summary: SELinux is preventing /bin/bash "create" access on resolv.conf. Detailed Description: [SELinux is in permissive mode. This access was not denied.] SELinux denied access requested by _updown.netkey. It is not expected that this access is required by _updown.netkey 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: You can generate a local policy module to allow this access - see FAQ (http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug report.

Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Major release. This request is not yet committed for inclusion. Fixed in selinux-policy-3.7.19-11.el6 Red Hat Enterprise Linux 6.0 is now available and should resolve the problem described in this bug report. This report is therefore being closed with a resolution of CURRENTRELEASE. You may reopen this bug report if the solution does not work for you. |
