Broadcast Traffic on Linux(FC-11) using iperf


Hi,

I tried to send UDP Broadcast traffic from Windows 7 machine to Fedora core 11 and one more windows xp machine using iperf.

On Windows 7 machine I used the following command
"iperf -c 192.168.1.255 -i 2 -t 60 -b 10000 -u"

On windows xp machine, I used
"iperf -s -i 2 -u"
It is able to receive broadcast packets

On fedora core 11 machine I used
"iperf -s -i 2 -u"

machine doesn't show any received packets.
I tried with both promisc mode enable/disable.
iperf version : iperf.2.0.4

Please someone help me in making this work.

Thanks in advance.
uv.

Did tcpdump show the packet on the interface?

hi arun,

Yes, I could see the packets in tcpdump. But in iperf, it is not seen.

Hi -

Did you try unicast packets to the listening iperf? Hope you have no firewalls configured.
