[netperf-talk] netserver fails to establish endpoint

[Edward Collins]

I tried an alternate port. It works in one direction but not the other direction.
Here's the failing case.

Thanks if you have any info or advice.

# ./netperf -p 12777 -H 172.24.50.21
TCP STREAM TEST to 172.24.50.21
recv_response: partial response received: 0 bytes

Here's the run from the working system side of he setup:

# ./netperf -p 12777 -H 172.24.10.33
TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 172.24.10.33 (172.24.10
.33) port 0 AF_INET

You could try typing:

ps -Af | grep netserver

and see if it prints out any line. Could be that your System automatically starts a netserver on startup.
Also you can try giving it a different Port by using:

netserver -p xxx

Where xxx is the portnumber (Should be greater than 1024 if you don't run as root)
If you do this, you need to also add the "-p xxx" option to the netperf commandline so that netperf doesn't try connecting on the normal Port.

As far as I know there is only on, is there a way to verify it?
Or who is using the ports.

I am very new to hp-ux.

thanks

This happens to me, if port 12865 is already in use. Do you maybe have another netserver running?

Has anyone else seen this error? I am setting up two systems for use and the
first one does the binding OK but the second one shows this.  Ver 2.4 netperf


# ./netserver
Starting netserver at port 12865
set_up_server could not establish a listen endpoint for  port 12865 with family
AF_UNSPEC

thanks, Ed
