[jira] [Commented] (SSHD-1296) Clientchannel returning null value as a command status (channel.getExitStatus).

    [ https://issues.apache.org/jira/browse/SSHD-1296?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17605538#comment-17605538 ] 

Thomas Wolf commented on SSHD-1296:
-----------------------------------

Try using heartbeats to keep the SSH connection open until the command terminates.

> Hi Team,
> We are using Apache mina SSHD to execute remote SSH commands while executing a remote SSH command on Linux which takes a long time to complete( more than 1 or 2hr.). but apache mina came out from the session and returned null as a response even though the command execution was not completed properly and the process is still running in the background. someone, please help me to overcome this issue. I also tried like channel.waitFor(ClientChannelEvent.EXIT_STATUS).  then the thread goes into a forever loop. I am using the apache mina  2.6.0 version and the java 1.8 environment.

> Thanks and Regards,
> Siva.
