From the command line, you could try:
telnet webserver_ip_address_here 80 (or whatever port you configured it to listen on) GET / [press enter twice and see if you see some html code] Basically that should give you a clue. Perhaps the webserver is not running for some reason (check your httpd-error.log) or perhaps the firewall is blocking port 80 on the webserver. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ "If you have nothing good to say about someone, just shut up!." -- Lucky Dube

if you are using a squid proxy, check its status. mis configured squid proxies usually result in frequent outages too. why dont you roll back your changes, then see if that sorts out your problem. re starting some fedora servers may also result in loss of iptable settings On 03/09/2009, I.

Please elaborate on this creation of an upload folder again. You needed to upload via Apache or via some other application? Mode 777 compromises your server badly. If I were you, I'd do mode 1777 instead, but that's just a suggestion. Is httpd running? Is there an errors you can see on the logs? Always look at the logs first as the clues are most likely there. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ "If you have nothing good to say about someone, just shut up!." -- Lucky Dube

I think there is another application using port 80; apachectl -k restart The line above is supposed to restart apache if its running or just start it if its not Permission denied: make_sock: could not bind to address 0.0.0.0:80<http://0.0.0.0/> The line above shows that it cannot use port 80. I am not sure what that "Permission denied:" there means, but making an educated guess, which user account is apache running with? Maybe that user account does not have sufficient permissions to "make_sock:" :-) Running apache as root is normally discouraged.
