Roberto Deandrea commented on SSHD-964:
---------------------------------------
Hi Lyor,
For local and remote port forwarding tunnels when sendEof() is executed,
isClosing() is always true because the channel is not in Opened state and the
SSH_MSG_CHANNEL_EOF is never sent.
_protected void sendEof() throws IOException {_
_if (isClosing()) {_
_if (log.isDebugEnabled()) {_
_log.debug("sendEof({}) already closing or closed", this);_
_}_
_return;_
_}_
...........................................................................
_public final boolean isClosing() {_
_return state.get() != State.Opened;_
_}_
When a SSH_MSG_CHANNEL_EOF is received In TcpipClientChannel.handleEof()
serverSession.shudownOutputStream() causes the socket between SSH client and
SSH server to be closed, and this is not the rigth behaviour.
_@Override_
_public void handleEof() throws IOException {_
_super.handleEof();_
_serverSession.shudownOutputStream();_
_}_
I hope this can clarify this issue.
Kind Regards
Roberto

> Project: MINA SSHD
> Issue Type: Bug
> Affects Versions: 2.3.0, 2.3.1
> Reporter: Roberto Deandrea
> Assignee: Lyor Goldstein
> Priority: Major
>
> We found that the message SSH_MSG_CHANNEL_EOF is never sent or received for
> local and remote port forwarding connections.
> We found probably the issue and we changed the code locally in a couple of
> java classes to fix this issue.
> Let me know if we can commit our changes in a pull request (into a specific
> Apache SSHD branch) so that you can peer review the changes and decide if
> you can accept them...
