[TYPO3-linux] Cannot access typo3 in browser

[M. Stanley]

I'm trying to install, learn and use typo3 v3.8.1 (quickstart) on a test box 
before rolling it out to production. I have successfully completed the 
initial install steps prior to using the 1-2-3 install tool in the browser, 
but that's where I run into problems. I can't pull up the typo3 site in 
Firefox to save my life...

I created a new virtual host .conf file and Apache can see it; I installed 
the quickstart AND source code packages; I changed permissions as directed 
by the Tgz-INSTALL.txt file... yet when I try to access the new typo3 site 
in the browser it says "firefox can't find the server" or "URL was not 
found"

I'm running RHEL WS4 w/ Apache (2.0.52), MySQL (4.1.12) and PHP (4.3.9-3.9).

Please help!

T.I.A.
