Thanks to Andrei, Russell, and Thomas for replying.
I am getting closer but still no cigar. I followed your advice on
running truss and here are the results
USER:
5515/1: open("/var/run/rpc_door/rpc_100029.2", O_RDONLY) = 8
5515/1: open("/dev/udp", O_RDONLY) = 9
5515/1: open("/dev/udp", O_RDONLY) = 9
5515/1: open("/dev/udp", O_RDWR) = 9
ROOT:
5633/1: open("/var/run/rpc_door/rpc_100029.1", O_RDONLY) = 8
5633/1: open("/dev/udp", O_RDONLY) = 9
5633/1: open("/dev/udp", O_RDONLY) = 9
5633/1: open("/dev/udp", O_RDWR) = 9
5633/1: open("/var/run/rpc_door/rpc_100029.2", O_RDONLY) = 8
5633/1: open("/dev/des", O_RDONLY) Err#2
ENOENT
5633/1: open("/dev/udp", O_RDONLY) = 9
5633/1: open("/dev/udp", O_RDONLY) = 9
5633/1: open("/dev/udp", O_RDONLY) = 9
5633/1: open("/dev/udp", O_RDONLY) = 9
5633/1: open("/dev/udp", O_RDONLY) = 9
5633/1: open("/dev/udp", O_RDONLY) = 9
As the user open("/var/run/rpc_door/rpc_100029.1", O_RDONLY) = 8 never
gets called, rpc_200029.2 gets created first. So I'm not sure if that
signifies anything.
The snoops look like this for udp traffic:
USER:

The user never sends the RPCBIND C GETTING packet to the server
(nyedsdev4). Apparently it is getting stuck opening /dev/udp as RW.
Thanks for reading.
