[mpich-discuss] mpdboot for ssh with password - a suggestion

[Swatch Puppy]

Hello,

The problem is that if your working without root privileges, like i am in
the school fedora images loaded from pxe to the lab's computer, maybe this
could be helpful. Additionally the fedora image is set up so that no ssh
without password can be made (don't ask me why or how).
I have to check hydra out, once that on my home computer i'm still using
mpdboot.

The best regards,
SwatchPuppy
