By changing the password back, you mean that your root password has actually been changed? If no, then you need to configure ssh to allow remote root login (not a good idea though). If yes, then it's almost a certainty that your system has been hacked. Wipe and install Fedora 8 or 9.

That wouldn't be my bet. I doubt someone that gained root access to the
machine would change the root password unless it was someone he knows
playing a prank on him. I expect there is something else going on here.

I wonder about pranks since the OP has posted the following on the ubuntu list:

    I have Ubuntu 7.10 installed on my machines. I strangely find
that I am often unable to login to the machine with my regular
root password using ssh. Fortunately I have physical access to the machine,
which allows me to change the password back. Any idea what could be
the reason? Is it necessarily evidence of my machine being hacked
into, or could it also have something to do with my messing around
with ssh keys etc.? What should I do to protect against both
possibilities. In other words if it is a security breach, how do I
plug it and prevent the "hacker" from having continued access.
    If the password change is a result of something else, what are
the possibilities I should address.
