SELinux is preventing /usr/sbin/httpd.worker from binding to port 9830.

Detailed Description:

[httpd.worker has a permissive type (httpd_t). This access was not denied.]

SELinux has denied the httpd.worker from binding to a network port 9830 which
does not have an SELinux type associated with it. If httpd.worker should be
allowed to listen on 9830, use the semanage command to assign 9830 to a port
type that httpd_t can bind to (ntop_port_t, http_cache_port_t, http_port_t).
If httpd.worker is not supposed to bind to 9830, this could signal an intrusion

Allowing Access:

If you want to allow httpd.worker to bind to port 9830, you can execute
# semanage port -a -t PORT_TYPE -p tcp 9830
where PORT_TYPE is one of the following: ntop_port_t, http_cache_port_t,
If this system is running as an NIS Client, turning on the allow_ypbind boolean
may fix the problem. setsebool -P allow_ypbind=1.

Comment 1 Miroslav Grepl 2010-04-23 12:04:14 UTC
Why is apache trying to listen to port 9830?

The troubleshoot message tells you what to do. For example:

semanage port -a -t  http_port_t -p tcp 9830
