wierd sudo problem?

[Matt Price]

hi there,

one of my students has done somehting wierd on his ubuntu system --
which I belive is properly instlaled, but can't be entirely sure! --,
and now the "sudo" command doesn't work.  so e.g., if I type:

echo "hello"

that works; if on the other hand I type:

sudo echo "hello"

I am asked for my password, but then just returned to the command line
with no action having been taken.  Since there's no root access on the
machine, I can't just login and explore what's going on, so I'm pretty
much at a loss.  Is there anything that might be done in this
instance?  ANyone have any idea what's going on?  I've never seen
sudo act this way before, 

thanks,

matt
