Hello,

My use-case requires running both owamp client and server programs in 
one common host to test a virtual network also in the host. Also the 
host happens to be a virtual machine, and the following 2 issues are 
encountered as a result.

1. The first is a well know issue of NTP synchronization in virtual 
machine. However instead of trying to make NTP configuration good for VM 
usage, is it possible to run owamp without NTP since anyways two test 
endpoints are in the same machine and hence no need of NTP?

2. The latency tests in direction from client (owping) to owampd 
(server) do not get started when they both are co-located in one host.

> owping -c 100 -i 0.01 -t 127.0.0.1:8965 -P 9000-9001
owping: FILE=protocol.c, LINE=1515, _OWPReadAcceptSession:Unable to read 
from socket.
owping: FILE=owping.c, LINE=200, Session Failed!

I haven't been able to debug the exact cause of it.

It will be really helpful if you can please provide your inputs on these 
two issues.


Kind Regards,
