Unable to start netserver with 'IN(6)ADDR_ANY' port '12865' when run netperf

-> When i execute below command i am getting the error like:
     $ netserver
        Unable to start netserver with  'IN(6)ADDR_ANY' port '12865'
and family AF_UNSPEC

This is because port might be busy, because of netserver is already running.
You can check port status using command netstat -ant|grep 12865. / or just
run ps x|grep netserver to see that netserver is already running.
You want to run in any other port(49152) use the command netserver
"netserver -p 49152 -L 172.28.132.100"


-> Please tell me How can i check the TCP/IP performance(Throughput)
for 15min  duration using "netperf" command. (On Linux and Genode
Microkernel).

netperf  -p 49152   -H 172.28.132.100 -L 172.28.132.79 -l 900 -t tcp_stream
this will run for 15 min(900 Sec) and check tcp_stream performance. You can
change test type also.
