Subject: Re: [OMPI devel] Ssh tunnelling broken in trunk?
From: Jeff Squyres (jsquyres_at_[hidden])

Can you diagnose a little further:

1. in the case where it works, can you verify that the ssh to launch

2. in the case where it doesn't work, can you verify that the ssh to
launch the orteds has actually died?
