> The rfc4253 does not indicate whether the ssh client must send its own
> version number right after receiving the version number of the server.
> I have encountered a situation where mina-sshd is used to connect to cisco's
> sshd service, sometimes it can be connected, sometimes not connected.
> Some rules are found by capturing packets. If the client sends its own
> version number after receiving the version number of the server, it can be
> connected. If the client sends its own version number before receiving the
> version number of the server, then it will not be connected.
> I think, a better way is to change the SshClient code to send the version
> number of the client right after receiving the version number of the server.
