netstat -an shows me an open "phantom" tcp6 port

[Thomas Vogt]

Hi

I'm confused. I've a new installed FreeBSD system. I'm running NFS, 
http, ntpd and a ftp server. If i look for open ports netstat shows me 
something on port 1000 (ipv6)

netstat -an | grep 1000
tcp6       0      0 *.1000                 *.*                    LISTEN

But sockstat shows me nothing:

sockstat -6 | grep tcp6
root     sshd       704   3  tcp6   *:22                  *:*
root     rpc.statd  599   6  tcp6   *:912                 *:*
root     rpcbind    597   8  tcp6   *:111                 *:*


Also lsof -i 6 -a -P shows me nothing on port 1000.

Any idea who i can figure out whats running on port 1000 with ipv6? Only 
the loopback interface has an ipv6 address.

System:
FreeBSD 7.2-RELEASE-p4 amd64

Thomas
