Hi Lidi greeterserver.py is running on a terminal from other terminal i can see that port 50051 is bound to python # lsof -i :50051 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME python 18126 root 6u IPv6 32226 0t0 TCP *:50051 (LISTEN) root@fmx215:~/gRPC/grpc/examples/python/helloworld#
I am behind corporate proxy; but i think they are working fine since I am able to reach ernal internet as well as reach to nodes on internal network i am not sure if corporate proxy would alter or redirect any traffic here. following is my /etc/hosts file 127.0.0.1 localhost 127.0.1.1 fmx215.xx.xxx.com fmx215 # The following lines are desirable for IPv6 capable hosts ::1 localhost ip6-localhost ip6-loopback ff02::1 ip6-allnodes ff02::2 ip6-allrouters I am still unable to get this example working. please let me know what else i can check or do to make it working thanks Ankit On Wednesday, November 7, 2018 at 4:40:59 PM UTC-8, li...@google.com wrote: > > Hi Ankit, > > After the greeter_server.py started, have you observed the port 50051 been > bound in your system?
