You mean you run "crontab -e", and then when it starts its editor
(vi by default) you enter "00 21 * * *  /sbin/ifdown eth0" then save
it?  Yes, that should work.  But why do you want this to be in your
own crontab, not /etc/crontab (or as /etc/cron.d/eth0down)?

This is a strange way to want to set a crontab... "man crontab"
seems to say it'll work, but the file might need to be executable or
something.

I presume you mean that the file "Eth0Dwn" contains that line.
What do you see when you "crontab -l"?

Why do you want to do this anyway?  Isn't it simpler to edit the
crontab directly with "crontab -e"?
