> Do you have tested both nodes with iperf?


Hi Igor

I'd love to test with iperf but it seems to do nothing for me.

On my "server" :

[root at mailstorage-1 iperf-1.7.0]# ./iperf -s -B 10.1.0.1
------------------------------------------------------------
Server listening on TCP port 5001
Binding to local address 10.1.0.1
TCP window size: 85.3 KByte (default)
------------------------------------------------------------
[  4] local 10.1.0.1 port 5001 connected with 10.1.0.2 port 33688


on the client :

[root at mailstorage-2 iperf-1.7.0]# ./iperf -c 10.1.0.1
------------------------------------------------------------
Client connecting to 10.1.0.1, TCP port 5001
TCP window size: 16.0 KByte (default)
------------------------------------------------------------


nothing changes. From what I can see, it should output some bandwidth
figures after 10 seconds ?

when I kill the client the server shows :

[ ID] Interval       Transfer     Bandwidth
[  4]  0.0-270.1 sec  0.00 Bytes  0.00 bits/sec


I tried again, using the bind address of the 1Gb adapter, but same
results.
