Hi,<br>
<br>
Sorry my mistake . I was actually trying it for different ports and
copied the earlier command on client VM. On client VM I am running<br>
<br>
iperf -c 192.168.1.42<br>
<br>
and on server <br>
<br>
iperf -s<br>
<br>
yes the server is listening on port 5001.<br>
<br>
netstat -anp | grep 5001<br>
(Not all processes could be identified, non-owned process info<br>
will not be shown, you would have to be root to see it all.)<br>
tcp 0 0 0.0.0.0:5001 0.0.0.0:*
LISTEN 20227/iperf <br>
<br>
Thanks,<br>
Priyanka<br>

<div>Hi Priyanka,<br>
</div>
Sorry for that. My bad. I actaully meant to say, check if
that client is indeed listening on the port.<br>
<br>
</div>
And wait a minute, I didn't notice!!!<br>

<div>Hi Priyanka,<br>
</div>
First check if you are able to ping the
client VM from the server VM on the specified
port. If not, then there is an issue with the
network configuration.<br>
</div>
Else, if you are able to ping on the specific
port, then there is some tunnelling issue and we
can fix that!<br>
</div>
Let me know this and we can proceed.<br>
