Description Geova Ramalho dos Santos 2010-02-08 12:35:32 UTC
Summary:

SELinux is preventing /usr/sbin/proftpd "search" access to /var/www.

Detailed Description:

SELinux denied access to /var/www requested by proftpd. /var/www has a context
used for sharing by a different program. If you would like to share /var/www
from proftpd also, you need to change its file context to public_content_t. If
you did not intend to allow this access, this could signal an intrusion attempt.

Allowing Access:

You can alter the file context by executing chcon -t public_content_t '/var/www'
You must also change the default file context files on the system in order to
preserve them even on a full relabel. "semanage fcontext -a -t public_content_t
'/var/www'"

Fix Command:

chcon -t public_content_t '/var/www'

Comment 1 Daniel Walsh 2010-02-08 20:52:39 UTC
Were you using webmin to manage ftp server?  Any reason why the ftp server would want to look at apache content?

Comment 2 Daniel Walsh 2010-02-09 21:02:58 UTC
Miroslav,

Please add

	# webmin seems to cause this.
	apache_search_sys_content(daemon)

To init.te/.
