Hello,
I can start a service as desired.
elfring@Sonne:~/Projekte/Bau/C++/test-statistic-server1/local>
./test-statistic-server2 & /usr/bin/ss -t -l -p -H|grep test
[1] 8961
waiting for connections
server_id: localhost
server_port: 35529
LISTEN 0 123 [::1]:35529 [::]:*
users:(("test-statistic-",pid=8961,fd=3))
elfring@Sonne:~/Projekte/Bau/C++/test-statistic-server1/local> 0 connections
were handled.
But I wonder about the following error message then.
elfring@Sonne:~/Projekte/Python> /usr/bin/python3
~/Projekte/Python/socket-send_json_data.py --server_id localhost --server_port
35529
Using Python version:
3.7.2 …
Traceback …:
…
File "/home/elfring/Projekte/Python/socket-send_json_data.py", line 17, in
send_data
so.connect((args.server_id, args.server_port))
ConnectionRefusedError: [Errno 111] Connection refused
How should this inter-process communication difficulty be resolved?
Regards,
Markus
