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

This netstat show exactly the same
boah then call it as root, for a unprivileged user it shows only executeable and PID of own processes for good reasons
Lsof does not show these ports
because you just have no permissions
My bad I should have said. My original commands were sudo netstat -tulpn | less sudo lsof | less I have several CentOS 6.5 machines and only one shows these odd ports. I have also run chkrootkit and used clamscan to check filesystems. It may be harmless but my curiosity is killing me.
