Re: Why do the mpi packages depend on rsh, etc?
Greetings! I don't know about mpich, but lam does have support for
using ssh in place of rsh. The problem is is that the default is a
compile time option, which can optionally be over-ridden at run-time.
So in building a Debian package, one has to choose a default, (which
should be rsh instead of ssh for most users, due to speed and the
internal network topology of most clusters), and if a dependency is
not made on that default, then the package simply won't work unless
the user sets their LAMRSH environment variable. I suppose one could
duplicate lam-runtime into a lam-runtime-ssh, but this seems a bit
excessive. If you want to use lam with ssh, just install rsh, disable
it in inetd, set LAMRSH="ssh -x", and you're ready to go!
Take care,
