Hi,
Under your guidance, the python code using ssh-agent ssh-add has been
running successfully. In addition to the code you wrote to me, I also
refer to man ssh-agent and subprocess: Subprocess management. I now know
the importance of environment variables.
This problem has puzzled me for nearly two weeks and solved this
problem with your help.
With your guidance and help, I have learned a lot. You are a very
good teacher. You are my teacher.
BTW, this program is for visit youtube.
Cheers!
Thanks so much.

lines = outinfo.split('\n')
for line in lines[:-1]:

varname, varvalue = left.split('=', 1)
print("got" + varname + "=" + varvalue)

Checking refusal of a network connection
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

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

How should this inter-process communication difficulty be resolved?

I prefer an other approach to clarify relevant software configuration

I can offer other data before.

I hope not.
I can try another server variant out as expected.

Can connections work also with a network service address like “[::1]:35529”
(which would be used by the C++ server implementation so far)?
How does the software situation look like for the support of the IPv6 loopback
address?

Spot the difference between the identifiers I underlined. If you run
this from the command line, the traceback tells you exactly what is
going on.

Did you look at the exception you get when this runs? It might
possibly be able to point you to the problem, and maybe suggest how
you could resolve it (by importing something, perhaps).

It looks like the service isn't listening at the time the so.connect is
called. Are you doing it before the service is ready?
Otherwise you need to print out the server_id and port, and examine the
system to see if that address/port is in LISTEN state. Running "netstat
-an" on the system running the service is a useful way to do this.
Hmm, look like your "ss" command effectively does that.
I'd fall back to the connect then: check that it really is using the
correct address/port. Print them out.
Also, it can be very useful to strace the client process, eg:
strace -e trace=network /usr/bin/python3
~/Projekte/Python/socket-send_json_data.py --server_id localhost --server_port
35529
You can also strace the running service process:
strace -e trace=network -p pid-of-service-process-here
to see if it is responding in any way to the client connect.
Also, on the service side it isn't enough to create the service socket,
you also need to do an accept IIRC. If you're using Python's socket
library the service classes do that for you.

Cameron Simpson
