I have no idea, what's the matter with port 1024 (looks suspiciously like 2^10, but I don't what's the significance of such similarlity).


Souhrn:

SELinux is preventing the npviewer.bin (nsplugin_t) from connecting to port
1024.

Podrobný popis:

SELinux has denied the npviewer.bin from connecting to a network port 1024 which
does not have an SELinux type associated with it. If npviewer.bin is supposed to
be allowed to connect on this port, you can use the semanage command to add this
port to a port type that nsplugin_t can connect to. semanage port -L will list
all port types. Please file a bug report
(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against the selinux-policy
package. If npviewer.bin is not supposed to bind to this port, this could signal
a intrusion attempt.

Povolení přístupu:

If you want to allow npviewer.bin to connect to this port semanage port -a -t
PORT_TYPE -p PROTOCOL 1024 Where PORT_TYPE is a type that nsplugin_t can
connect.
