How to use "/multi:" method in tramp with emacs23?

How to use "/multi:" method in tramp with emacs23?

[Nikos Apostolakis]

Hello group,

the following syntax works for tramp in emacs22

/multi:ssh:me@host1:ssh:me@host2:/path/to/file

where host2 is a host that I can acces only from host1.  This
doesn't seem to work with emacs23 anymore.  Whenever I try such
paths I get the message

File error: Process has died
tramp-error: Process has died

and a buffer named *tramp/ssh ssh* containing:

ssh: ssh: Name or service not known

Anybody knows how to fix this?

I am using the emacs-snapshot package for Debian:

(version)
"GNU Emacs 23.0.50.1 (i486-pc-linux-gnu, GTK+ Version 2.12.0)
 of 2007-09-30 on elegiac, modified by Debian"

(tramp-version t)
2.1.11-pre

TIA,
Nikos

From etc/NEWS (`C-h n'):

    *** Multihop syntax has been removed.
    The pseudo-method "multi" has been removed.  Instead of, multi hops
    can be specified by the new variable `tramp-default-proxies-alist'.

I see, thanks for your answer.  For some reason the emacs snapshot
package has the info documentation for an older version of tramp and
I did't think to look at the news.  I found the documentation in the
web but stil I am not sure how to set the variable
`tramp-default-proxies-alist' to accomplish what the old "/multi"
syntax did.  In the above example I have the ip addresses of host1
and host2, how should I set the variable?

Thanks,
Nikos

(add-to-list 'tramp-default-proxies-alist
             '("host2" "me" "/ssh:me@host1:"))

Ok, I did that, but it didn't work.  Just to make sure, after
setting the variable, to open the file "/path/to/file" in host2 I
should do "C-x C-f /me@host2:/path/to/file", right?  When I do that 
I get the message "File error: Permission denied" and a buffer 
named *ssh me@host2* containing "ssh: ssh: Name or service not known"
I also tried "C-x C-f /ssh:me@host2:/path/to/file" with the same 
results.

With emacs22 on the same machine I can connect to host2 via host1.

Thanks again,
Nikos
