I see. You can buy a router. And use router with your student account to login.
Your colleage will guide you.

We are using the campus network, only one IP can be assigned to one  student account, so I
think it's not pratical to use bridged mode.  Thanks for the advice though.

You should change your vm to bridge.

 NAT with VM.
You just make sure SSH to VM without password.


But the best way is start to try it now.

Hi,


 May I ask how you configured the VM? The hadoop on other machines can just access the VM
guest on another machine without port forwarding? (just making sure I'm not being paranoid
here :) )

 Hi,

connect to other nodes in this way. To my knowledge the port for the tasktracker is uncertain,
so I can't forward a specific port for it.
