SymptomsParallels H-Sphere Control Panel can not pass PCI (payment card industry) scan because off the following security information found on port/service "sunrpc (111/tcp)":
ResolutionFilter incoming traffic to TCP port 111 if desired.
# netstat -anp|grep 111
tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN 1597/portmap
udp 0 0 0.0.0.0:111 0.0.0.0:* 1597/portmap
The portmapper manages RPC connections, which are used by protocols such as NFS and NIS.
Disable the service if NFS/NIS not used. In other case, filter out all not needed requests.
To disable the service, run:
# service portmap stop
# chkconfig portmap off
# chkconfig --del portmap
