Of course I didn't find it anywhere, that's the port on my wife's box
that port 947 was connected to.
Now I even went over to my wife's box and ran
# rpcinfo -p localhost
program vers proto port service
100000 4 tcp 111 portmapper
100000 3 tcp 111 portmapper
100000 2 tcp 111 portmapper
100000 4 udp 111 portmapper
100000 3 udp 111 portmapper
100000 2 udp 111 portmapper
100024 1 udp 34243 status
100024 1 tcp 34498 status
which doesn't show anything.
but something is listening to that port...
# netstat -ntap |grep 55201
tcp 0 0 0.0.0.0:55201 0.0.0.0:* LISTEN
I rebooted again, but this time I ran this on my wife's box:
# trace-cmd record -e nfs -e nfs4 -e net -e skb -e sock -e udp -e workqueue -e sunrpc
I started it when my server started booting the kernel, and kept it
running till the port vanished.
The full trace can be downloaded from
http://rostedt.homelinux.com/private/wife-trace.txt
Here's some interesting output from that trace:
