def Testsshcon(ip,port,username,password):
    try:
        sshcon=paramiko.SSHClient()

        cmds=['dis cpu\n','dis version\n']
        conn=sshcon.invoke_shell()
        for cmd in cmds:
            time.sleep(1)
            conn.send(cmd)
            time.sleep(1)
            print "command"
            out=conn.recv(1024)
            print out
        sshcon.close()
    except Exception,e:
        print "connet error",e
