Hello!
I am trying to implement a server and a client using docker containers and setup communication, however when I ran <make tests -e LTESTS=""> on either server or client the following error occurs:

...
...
make[1]: Entering directory '/home/ssh_project/openssh/regress'
run test putty-transfer.sh ...
putty transfer data: compression 0
putty transfer data: compression 1
/home/ssh_project/openssh/regress/test-exec.sh: 377: kill: No such process

/home/ssh_project/openssh/regress/test-exec.sh: 385: kill: No such process

sshd died without cleanup
make[1]: *** [Makefile:239: t-exec-interop] Error 1
make[1]: Leaving directory '/home/ssh_project/openssh/regress'
make: *** [Makefile:730: interop-tests] Error 2

sorry for bringing up silly problems, but I have been stucked for too long. I would appreciate any suggestions.

the following is the full log message

Difficult to comment without knowing the environment/setup you're using.... Have you tried using the ready-made docker image at docker hub openquantumsafe/openssh? Or used the Dockerfile in oqs-demos?

yes, this error appears when using the openquantumsafe/openssh docker image

Hmm -- there is no directory named "/home/ssh_project" in the openquantumsafe/openssh image. Please provide exact steps to reproduce.

Here is what I did: first I pulled the image from the docker hub, created a container with it, attached, entered folder home and mkdir ssh_project and entered;
Next I did git pull and processed steps in Quick start.
Then I saved this container as a separate image, and created two new container name server and client.
I tested "python3 oqs-test/try_connection.py" on both with no error occurring. it is very confusing to me why "make tests -e LTESTS=""" cannot work as expected.

Thanks for the description -- but I can't quite follow it. Could you please share commands/files?

Somewhat confusing is

entered folder home and mkdir ssh_project and entered;

What did you enter?

Most confusing is this statement:

I tested "python3 oqs-test/try_connection.py" on both with no error occurring.

So everything is OK?

"make tests -e LTESTS="""

Can you please state which of the various containers you executed this in (and how exactly you created the corresponding image)?

apologies for making you feel confused!

To start with, I created a container from the openquantumsafe/openssh image, named container0

by entered I mean cd from the root directory into several subfolders
$ cd home/ssh_project/openssh
home folder exists when the container was created; ssh_project is a folder I created; openssh is the resources pulled from open quantum-safe GitHub.

After going through processes in Quickstart - Building OQS-OpenSSH, I tried python3 oqs-test/try_connection.py and got
Success! Key Exchange Algorithm: classic-mceliece-348864-sha256. Signature Algorithm: ssh-ecdsa-nistp256-sphincssha256128fsimple.

To store the above changes in order to duplicate, I ran
docker commit container0 ssh_image

Next, I created a server and a client container from ssh_image
and last I started those two containers, tried to run make tests -e LTESTS="" and result in the above messages in either of the containers.

Thanks for the additional information. I still cannot follow what you did: By creating "a container from the openquantumsafe/openssh image" you a) do not get the tooling required to build oqs-openssh -- making the subsequent steps you describe impossible and b) already have a working oqs-openssh image -- so why do you need to re-build it? So for example, did you re-build liboqs as per the Quickstart or did you just use the executables already built into the image?

I apologize for having to conclude that

I cannot invest more time into a question not coming with a script allowing immediate reproduction of the problem
there are colleagues more deeply involved with the oqs-openssh subproject, so I'd like to ask @christianpaquin @xvzcf to take a look.

Finally the question to @xvzcf whether this discussion shouldn't be moved to open-quantum-safe/openssh (I don't have permission to do so).
