> Hi,

> Git client has been ported to HPE NonStop. This OS is Posix called OSS.

> Currently this git client works with openSSH ssh client also ported to
> OSS.
>
> When we try to use our "native" ssh client, a custom written ssh
> client, using GIT_SSH= to point to it we are running into some
> problems. We are this custom ssh developers.
>
> The problem is there is establish connection to Gitlab, the server,
> and some work is done between git client and git server, but then it
> seems git client just sits waiting. We can't figure out what it
> waiting for not knowing this client/server protocol and would need
> some way of knowing to more productively debug our custom ssh client

> We are not an actor in the communication between git client and git
> server, we just transport data packets transparently with ssh. So
> either one of the communication partners do not go on with the
> protocol or some data is stuck in ssh (or the pipe server on the OS).
> We can only know the details if we know what the git server
> sent/received and what we sent/received. From our side the only thing
> we can do is to dump the data from the git server when we receive it.
> Beyond that we need the data dump from the git server and the git
> client. Additional state info from the git client and server would
> help to understand what went wrong, which data is missing, which state
> it is in.

> How can we get more info from git client? Any helps suggestions welcomed?
