I seem to still be using the old format.

In this particular case, I'm ssh'ing from a Debian-woody workstation to a
FreeBSD server, but I get the same results from all of the various
client/server combinations I've tried.  Also note that single-hop
connections have always worked perfectly for me, which is why this never was
a high-priority item for me.  However, I've recently grown very tired of
using 'vi' on remote servers to edit config files.  :)



Here is *tramp/multi address@hidden:address@hidden:* :
