Testing internet connection reliability

["Ben Beuchler" <insyte@emt-p.org>]

I'm starting to play with my new DSL, running qmail and Apache servers...
Even have a domain or two of my own.  I would like to be able to provide
e-mail forwarding for my friends and maybe host their personal sites.
However, I'm a little nervous about the reliability of my internet
connection.  Is there some sort of script or program that will test it at
regular intervals (maybe pinging a reliable host) and log the results?

I imagine I could patch something together to ping Yahoo! or something but
I'm sure there are more variables to consider then I've thought of...

Thanks,
Ben
