I have cross-compiled the code successfully for QNX ARM 7.0, and able to 
generate the binaries.


Very first thing I am going to do is to run the helloworld code on the 
target. So I built the helloworld code available in cpp folder(since I am 
using cpp). 


I copied only two files greeter_server and greeter_client in target 
machine. I am able to start server using greeter_server successfully. But 
when I run greeter_client in another window, I get failure message.

14: DNS resolution failed
Greeter received: RPC failed

Here is the logs 
<https://drive.google.com/file/d/1_kv0PxlcvzHlffVxdQn-KkBBmALQ3x2P/view?usp=sharing>
 after 
enabling GRPC_TRACE=ALL, GRPC_VERBOSITY=DEBUG.


Please help me know the issue.


We do not have DNS server, I tried using GRPC_DNS_RESOLVER=native, but did 
not helped. 


Do we need DNS? If its not DNS then, what is it failing?



Thank you in advance.
