Description Harjit Singh Mavi 2007-08-22 01:51:47 UTC
Description of problem:
Summary
    SELinux is preventing /usr/sbin/in.tftpd (tftpd_t) "create" to <Unknown>
    (tftpd_t).

Detailed Description
    SELinux denied access requested by /usr/sbin/in.tftpd. It is not expected
    that this access is required by /usr/sbin/in.tftpd 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
    http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385 Or you can disable
    SELinux protection altogether. Disabling SELinux protection is not
    recommended. Please file a http://bugzilla.redhat.com/bugzilla/enter_bug.cgi
    against this package.
