Try to connect androidTV via SSH

I have some problems with SSH connection, I've started the SSH server on my androidTV(it's root), and I've seen connection, but commands didn't run on the device. I'm trying to run vlc-stream on androidTVs. If I use putty for connection, I have no problem, but my program not working. I`m using jcaft.

It`s class for connect

           String password, String connectionIP, String knownHostsFileName)
