99 times out of ten, it means that there is already something running, bound to 
port 12865.  Perhaps an older version of netserver or something else - before 
starting netserver try "netstat -an | grep 12865" and see if that shows anything.

There is no call for the second line - netperf will never use UDP for the 
control connection.  Also, editing /etc/services is merely to provide a 
convenient service name to port number mapping, nothing more.

What leads you to believe that is not a proper result?  Particularly if there is 
already a netserver running on the PC.

happy benchmarking,
