---------------------------------------------------------------
The problem is your client really. It may work on openssh but it still does
not follow the SSH protocol correctly.
A workaround could be to hack the following file:
https://github.com/apache/mina-sshd/blob/master/sshd-core/src/main/java/org/apache/sshd/common/session/AbstractConnectionService.java#L61
Instead of
{code}
protected static final AtomicInteger nextChannelId = new AtomicInteger(100);
{code}
you can try with
{code}
protected final AtomicInteger nextChannelId = new AtomicInteger(0);
{code}
It should work better, but the client is still broken and other use cases could
fail, for example if using port forwarding where the client does not control
channels.
