• Question 156:

  Examine the sequence:

  # sealert -l dda34207-61fd-4de2-831d-039c79270864

  SELinux is preventing /usr/sbin/httpd from read access on the

  file /var/www/manual/new_features_2_2.html.

  ***** Plugin restorecon (85.9 confidence) suggests *****

  If you want to fix the label.

  /var/www/manual/new_features_2_2.html default label should be httpd_sys_content_t.

  Then you can run restorecon.

  Do

  # /sbin/restorecon -v /var/www/manual/new_features_2_2.html

  ***** Plugin catchall_boolen (7.33 confidence) suggests *****

  If you want to allow httpd to read user content

  Then you must tell SELinux about this by enabling the `httpd_read_user_content' boolean. You can read

  `user_selinux' man page for more details.

  Do

  setsebool -p httpd_read_user_content 1

  What action must you take for fix this problem?

  A. Relabel the file in question by using the restorecon command.

  B. Allow httpd to read user content by using the setsebool command.

  C. Allow httpd to read home directories by using the setsebool command.

  D. Report a bug.
