SELinux is preventing /usr/sbin/httpd "name_bind" access .
Last modified: 2010-05-03 14:23:50 EDT
Summary: SELinux is preventing /usr/sbin/httpd "name_bind" access . Detailed Description: [SELinux is in permissive mode. This access was not denied.] SELinux denied access requested by httpd. It is not expected that this access is required by httpd 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.

Did you setup your httpd server to listen on port 8000?
yes, sometimes i need to test php app, that for some reason demand everything to be in document root, i have recently set virtualhost configured in apache to listen and respond to http://localhost:8000 for one such app. But even before i established that virtual host and added "Listen 8000" directive in apache configuration files, I regularly have in /var/log/httpd/error_log lines like that ( when httpd starts) [error] avahi_entry_group_add_service_strlst("marina-home") failed: Invalid host name I am not sure if that has something to do with "name_bind" in /etc/hosts I have: -------------------------------------------------------------------------- 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 marina-home.localdomain ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 marina-home.localdomain
Listen 8000 <VirtualHost _default_:8000> ServerAdmin marinalan@shaw.ca DocumentRoot /home/marina/<some_directory_webroot_of_tested_php_app> ServerName marina-home Options FollowSymLinks </VirtualHost>
I needed to use some port, because i use ssh remote port forwarding to have public url
You can add this port by using audit2allow # grep name_bind /var/log/audit/audit.log | audit2allow -M myhttp # semodule -i myhttp.pp If you want to have a document root in /home/marina you will need to setup this directory to have labeling of httpd_sys_content_t. # semanage fcontext -a -t httpd_sys_content_t /home/marina ' /<some_directory_webroot_of_tested_php_app>(/.*)?' # restorecon -R -v /home/marina /home/marina/<some_directory_webroot_of_tested_php_app>
