SELinux is preventing /usr/bin/mpd "name_connect" access .
Last modified: 2011-06-01 11:32:46 EDT
Summary: SELinux is preventing /usr/bin/mpd "name_connect" access . Detailed Description: [mpd has a permissive type (mpd_t). This access was not denied.] SELinux denied access requested by mpd. It is not expected that this access is required by mpd 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.

Hash String generated from catchall,mpd,mpd_t,http_cache_port_t,tcp_socket,name_connect audit2allow suggests: #============= mpd_t ============== allow mpd_t http_cache_port_t:tcp_socket name_connect;
You can add this rule for now using # grep mpd /var/log/audit/audit.log | audit2allow -M mympd # semodule -i mympd.pp
(In reply to comment #1) Thank you for help me!
Which PORT_TYPE? Next message: Summary: SELinux is preventing /usr/bin/mpd from connecting to port 8010. Detailed Description: SELinux has denied mpd from connecting to a network port 8010 which does not have an SELinux type associated with it. If mpd should be allowed to connect on 8010, use the semanage command to assign 8010 to a port type that mpd_t can connect to (ldap_port_t, dns_port_t, http_cache_port_t, http_port_t, pulseaudio_port_t, kerberos_port_t, ocsp_port_t). If mpd is not supposed to connect to 8010, this could signal a intrusion attempt. Allowing Access: If you want to allow mpd to connect to 8010, you can execute semanage port -a -t PORT_TYPE -p tcp 8010 where PORT_TYPE is one of the following: ldap_port_t, dns_port_t, http_cache_port_t, http_port_t, pulseaudio_port_t, kerberos_port_t, ocsp_port_t.

(In reply to comment #4) > Fixed in selinux-policy-3.7.19-34.fc13 Are you sure? I used selinux-policy-3.7.19-34.fc13. You fixed in -35.
Oops. Yes, you are right. I will build -35 release today. Thanks.
selinux-policy-3.7.19-37.fc13 has been submitted as an update for Fedora 13. http://admin.fedoraproject.org/updates/selinux-policy-3.7.19-37.fc13
selinux-policy-3.7.19-37.fc13 has been pushed to the Fedora 13 testing repository. If problems still persist, please make note of it in this bug report. If you want to test the update, you can install it with su -c 'yum --enablerepo=updates-testing update selinux-policy'.

This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
This message is a reminder that Fedora 13 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 13. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '13'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 13's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 13 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
