Thomas Wolf commented on SSHD-1308:
-----------------------------------
Like OpenSSH, Apache MINA sshd sends the channel requests for setting
environment variables with {{{}want-reply = false{}}}.
You could implement this yourself, but it'd be quite involved. Better figure
some other way to pass data to the server-side command, for instance via
command arguments.

> Project: MINA SSHD
> Issue Type: Improvement
> Affects Versions: 2.9.1
> Environment: Java 8
> Reporter: dgü
> Priority: Major
>
> Hello!
> If an environment variable set by
> _org.apache.sshd.client.session.ClientSession#createExecChannel(command,null,env)_
> is ignored by SSH server and exit code returns 0, then this may cause
> unexpected behaviour in client application.
> For example, client application may do different tasks when an environment
> variable is set and not set. In both cases, client application may return 0.
> Client application may assume that it worked successfully. But, indeed its
> environment variable is ignored and worked as if environment variable is not
> set.
> is it possible throw an exception if setting environment variable is ignored
> by SSH server ?
> Thanks in advance...
