    Im developing an application to connect in a plataform and execute some commands, but this plataform isnt a common computer. She is like and router who communicates ssh.

    When i try to connect using J2SSH lib's i got this message: 

    com.sshtools.j2ssh.transport.TransportProtocolException: The protocol version of the remote computer is not supported!

    And i know that, but i take the risk of connect and execute commands on her. There is a way to do it? Ignore this problem of version...

      What version is it? A log would be helpful showing the full stack trace.

      I only can offer the return off comand "ssh -v <hostname>" executed by my computer, because im not resposable for this plataform and the company that is, probably cant provide this to me.

      I'm doing these test's in production, there is no ambient of test's

      Here is the result of "ssh -v <hostname>":

      OpenSSH_5.2p1, OpenSSL 0.9.8k 25 Mar 2009

      In another research i've discovered that what cause this exception is this line:
      debug1: Remote protocol version 1.5, remote software version HUAWEI-VRP3.1
      debug1: no match: HUAWEI-VRP3.1

      But what i cant understand is why i can connect trought the terminal, and cant trought the code. It has to be a way for ignore this version or something like that!
