Open file via SSH and Sudo with Emacs

I want to open a file using sudo (say, /etc/hosts) on a remote machine connected by ssh using TRAMP on Emacs.

I tried couple of options, but none of them worked. Can anybody tell me how to go about it?

Thank you

Use following in your .emacs

(set-default 'tramp-default-proxies-alist (quote ((".*" "\\`root\\'" "/ssh:%h:")))) 

Then you can simply type:

C-x C-f /sudo:root@host[#port]:/path/to/file 

It will ask you for your password to access remote shell and then your password again for sudo access.
