[netperf-talk] Running Netperf using IPv6

[Ashenafi D]

Hi Rick,

Using netperf 2.4.3 I got the same error as in 2.4.1. When running
netperf using IPv6 addresses, server starts fine but the client fails to
establish control connection:

SERVER:
--------------
[machine-1 ~]$ netserver243 -6
Starting netserver at port 12865
Starting netserver at hostname ::0 port 12865 and family AF_INET6
[machine-1 ~]$
[machine-1 ~]$ ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:09:3D:00:08:C6
          inet addr:172.29.236.137  Bcast:172.29.239.255  Mask:255.255.252.0
          inet6 addr: fe80::209:3dff:fe00:8c6/64 Scope:Link
....

CLIENT:
-----------
 [machine-2 ~]$ netperf243 -H fe80::209:3dff:fe00:8c6 -6
establish control: are you sure there is a netserver listening on
fe80::209:3dff:fe00:8c6 at port 12865?
establish_control could not establish the control connection from ::0 port 0
address family AF_INET6 to fe80::209:3dff:fe00:8c6 port 12865 address family
AF_INET6
[machine-2 ~]$


Running netperf with strace shows there is an invalid argument when connect
call is used, but not quite clear which argument is invalid.
The only argumet I used in the command line is the IP addres and I was able
to ping the server using this IP address.

 [machine-2 ~]$strace netperf243 -H fe80::209:3dff:fe00:8c6 -6

I really appreciate your help,
