Re: [grpc-io] Re: python quick start "hello world" example fails

2018-11-19 Thread 'Srini Polavarapu' via grpc.io

Your connection issue is due to proxy configuration on your machine. As you 
can see gRPC is connecting to a proxy for localhost.
http_connect_handshaker.cc:300] Connecting to server localhost:50051 via 
HTTP proxy ipv4:10.19.8.225:912

Try setting http_proxy= or try no_proxy=localhost.

Hi Ankit,

To define variables in separate line, you need to export them to the whole 
environment like this:

$ export GRPC_VERBOSITY=DEBUG
$ 
export GRPC_TRACE=api,channel,call_error,connectivity_state,http,server_channel

Then you can run the examples:

$ python greeter_client.py
$ python greeter_server.py

The debug logs will go out through standard error output, which will print 
on your terminal.

 Hi Ankit,

 Sorry to hear that none of the fixes work for you. If the server is 
 started and able to bind tcp port, there is a great chance that this might 
 due to some local network setting.

 To detect whether there is a local network issue or gRPC Python issue, 
 can you try to start other applications that bind a port and try to 
 communicate with it?

 For example, you can try:

 $ python -m SimpleHTTPServer 8000
 $ curl http://localhost:8000
 # Or visit this address in browser, it should show up a valid HTML web 
 page

 or

 $ nc -6 -l 1234  # in one

Hi Ankit,

There is one more thing I would like to try. Can you provide the detailed 
tracing log for the example server and client?
The trace and debug logs can be turned on by setting environment variables.

$ GRPC_VERBOSITY=DEBUG 
GRPC_TRACE=api,channel,call_error,connectivity_state,http,server_channel 
python greeter_server.py
$ GRPC_VERBOSITY=DEBUG 
GRPC_TRACE=api,channel,call_error,connectivity_state,http,server_channel 
python greeter_client.py

 Hi Ankit,

 After the greeter_server.py started, have you observed the port 50051 
 been bound in your system? Also, have you use any sort of VPN or local 
 proxy that may redirect the traffic? One more check, is there a loopback 
 entry for 'localhost' in your /etc/hosts?

[grpc-io] Re: python quick start "hello world" example fails

2018-11-09 Thread lidiz via grpc.io

Hi Ankit,

I span up a Ubuntu 16.04 machine to investigate this issue. I used the 
default Python2.7, and installed `pip` through `get-pip.py`. And I 
Installed `grpcio` through `pip`.

Here are the version infos of my machine:
$ uname -a
Linux lidiz-dev-ubuntu-16-04 4.15.0-1023-gcp #24~16.04.1-Ubuntu SMP Wed Oct 
10 20:39:59 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

$ pip show grpcio
Name: grpcio
Version: 1.16.0
Summary: HTTP/2-based RPC framework
Home-page: https://grpc.io
Author: The gRPC Authors
Author-email: grpc-io@googlegroups.com
License: Apache License 2.0
Location: /home/lidiz/.local/lib/python2.7/site-packages
Requires: six, enum34, futures
Required-by: grpcio-tools

The command I run to get example to work:
# Installation
$ curl https://bootstrap.pypa.io/get-pip.py | sudo python
$ python -m pip install grpcio grpcio-tools googleapis-common-protos --user 
# Install gRPC and dependencies for the example

# First Terminal
lidiz@lidiz-dev-ubuntu-16-04:~/src/grpc/examples/python/helloworld$ python 
greeter_server.py

# Second Terminal
lidiz@lidiz-dev-ubuntu-16-04:~/src/grpc/examples/python/helloworld$ python 
greeter_client.py
Greeter client received: Hello, you!

It works on my machine, I guess there is a difference in the settings. I 
will continue to investigate this.

Hi Ankit,

Sorry to hear that none of the fixes work for you. If the server is started 
and able to bind tcp port, there is a great chance that this might due to 
some local network setting.

To detect whether there is a local network issue or gRPC Python issue, can 
you try to start other applications that bind a port and try to communicate 
with it?

For example, you can try:

$ python -m SimpleHTTPServer 8000
$ curl http://localhost:8000
# Or visit this address in browser, it should show up a valid HTML web page

or

$ nc -6 -l 1234  # in one terminal
$ echo 'Hello' | nc localhost 1234 # in another terminal
# The 'Hello' should appear in the first terminal

If one of those work, then there might be some issue with gRPC Python. If 
so, can you provide your gRPC Python version as well?
# Check your gRPC Python version
$ pip show grpcio

Bests,
Lidi

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 root6u  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

[grpc-io] Re: python quick start "hello world" example fails

2018-11-07 Thread lidiz via grpc.io

Hi Ankit,

After the greeter_server.py started, have you observed the port 50051 been 
bound in your system? Also, have you use any sort of VPN or local proxy 
that may redirect the traffic? One more check, is there a loopback entry 
for 'localhost' in your /etc/hosts?
