For Tracy and others who might be interested.

After some experimentation, I have had success with the method described in the Tramp user manual for using sudo on a remote host: http://www.gnu.org/software/tramp/#Multi_002dhops.

For example, let’s say you connect to the domain yellow.chalk with the user manerva:

(add-to-list ‘tramp-default-proxies-alist
‘(”yellow.chalk” “\\`root\\’” “/ssh:manerva@%h:”))

Using the above rule, you would do C-x C-f /sudo:yellow.chalk:
You would then be prompted first to login via ssh, and subsequently, if all goes well, you will get the sudo prompt. You can then find a file as usual.

Tracy,
I’m searching for a solution to the same issue. If I find anything, I’ll leave a reply here.

Sometimes it does gives just a couple of errors, but other times it just keeps coming. Well… hopefully they’ll fix it in the future.

Ritchie: I just opened a file on a remote machine with tramp and got this error, but only the first time it was opened. doing pabbrev-scavenge-buffer works, and after that pabbrev works normally, but I don’t know what as causing it.

I’m wondering if you have ever had any problem with using tramp and pabbrev-mode in emacs 23. Tramp version is 2.1.15 in emacs 23 and is extremely slow comparing to 2.0.58-pre. When the pabbrev-mode try to scavenge words in a opened file, tramp keeps giving some file error, complaining about invalid lisp expression, virtually makes me unable to edit the file while in pabbrev-mode with tramp. Have you experienced something like this?

Right. But we like sudo. Logging in as root is discouraged and some machines (Ubuntu especially) don’t even have a root password. It is nice not having a root password because then you don’t have to worry about memorizing/securing it. We just use sudo for everything. Even for console access our machines drop you to a root prompt in single user mode, never need the password.

Tracy: If you have the root password, you should just be able to do:

C-x C-f //ssh:root@hostname:path/to/file

My problem has always been: How do I use Tramp to open another file using sudo on ANOTHER computer. I’m a sysadmin and would like to be able to use emacs a lot more than I do. Here you show us how to edit files on another computer and how to edit files as root on the local computer. I need to combine these two.

Nevermind that last comment. That’d only work w/ the same buffer and the same file.
