I am running CentOS 6.5. I know this is not a CentOS specific problem.
Netstat shows several open ports and no pid.

tcp    0  0 *:48720                 *:*                 LISTEN      -
tcp    0  0 *:43422
*:*                 LISTEN      -
udp    0  0 *:50216                 *:*

alias netstat='/bin/netstat --numeric-hosts --numeric-ports --notrim
--programs -u -t'
       /bin/netstat

This netstat show exactly the same. Lsof does not show these ports.

This looks like these port are opened by kernel, not by a process, for
example like nfs.


How can I know for sure?
