You could possibly use rsh (if you have a .rhosts file). I just tested
it on Solaris, and it doesn't use /bin/login when running a remote command,
so maybe Linux is similar.

Eg:

rsh hostname csh -i

It'll give you a prompt, but no tty, so you won't have access to full
screen editors or anything like that. But it might be enough to allow you
to su to root and copy back /bin/login (you may have to use something like
snarf or wget to fetch it from somewhere if it's not on the box already).

But a bootdisk is probably easier ;)

Cheers,

Paul.
