K4 Really struggled

Hi everyone.

I have just got my Kindle 4 NonTouch (silver) and I am a total newcomer for Kindle. Please DO NOT be annoyed by my silly questions..., as I really really need your help

I want to run the vnc viewer. But I am totally stucked and couldn't the tutorials : http://www.mobileread.com/forums/sho...d.php?t=150434

I have Jail Broken my K4 (4.1.0). But I found it does not allow SSH access from putty.

Because of no SSH access, I think I suppose to install the USBnet first. For all the discussion about USBnet, it has a link : http://www.mobileread.com/forums/sho...88&postcount=1 However, I really CANNOT find how to install and how to use USB networking from that link.

I have searched/googled since 48 hours ago and I still could work this out. If you have any ideas, could you please give me some hints?
