             Summary: SSHD port forwarding. Missing SSH_MSG_CHANNEL_OPEN_FAILURE message
                 Key: SSHD-799
                 URL: https://issues.apache.org/jira/browse/SSHD-799
             Project: MINA SSHD
          Issue Type: Bug
    Affects Versions: 1.7.0
            Reporter: Fulvio Cavarretta

Hi we are faceing issue using port forwarding feature.

An ssh client is requesting to open a remote connection through Apache sshd server.

In case connection to remote server fails, there some cases where sshd do not send back SSH_MSG_CHANNEL_OPEN_FAILURE.

The problem is in _org.apache.sshd.common.session.helpers.AbstractConnectionService_ class 

The offending code seems to be from line 642 to 654: in case Exception is null, no SSH_MSG_CHANNEL_OPEN_FAILURE
is sent back to client.

We'll try to post a pull request for this issue
