Please keep replies on the list.
I would suggest running tcpdump on the server side and see if the
packet is
making it to the stack then. Perhaps there are other UFW rules
dropping things?
You can just use something like 'telnet 192.168.1.42 5001' to verify
that.

Sir,
I added rule tcp 1 65535 but it still did not work.
Thanks,

Like Krishna asked, have you added a security group rule for TCP
port 5001?
Otherwise ingress traffic on that port will be dropped.

Hi,
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
iperf -c 192.168.1.42
and on server
iperf -s
yes the server is listening on port 5001.
netstat -anp | grep 5001
(Not all processes could be identified, non-owned process info

Hi Priyanka,
Sorry for that. My bad. I actaully meant to say, check if that
client is
indeed listening on the port.
And wait a minute, I didn't notice!!!
Your output says:
On iperf server VM
| iperf -s
------------------------------------------------------------
Server listening on TCP *port **5001*
TCP window size: 85.3 KByte (default)
------------------------------------------------------------|
On iperf client VM
| iperf -c 192.168.1.42 *-p 8042* -i 1 -t 10

|Kindly let me know as to why are you using port 8042 in the
client while
the server
is listening on port 5001?

Hi Priyanka,
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.
Else, if you are able to ping on the specific port, then
there is some
tunnelling issue and we can fix that!
Let me know this and we can proceed.
Regards,
Nitish B.
