Apache shows "welcome" message instead of directory index for virtual host root

By default on CentOS, Apache will show the "welcome" page instead of the directory index for the virtual host root, even if you've added "Options Indexes" in the root directory definition in httpd.conf or in the .htaccess file for that directory.

So annoying. Seriously guys.

The AMAZING SECRET is /etc/httpd/conf.d/welcome.conf - this overrides the index option for any virtual host root. You can either comment out all the lines or edit the LocationMatch regular expression to not match a given host.

force default gateway through eth0

On a CentOS 5.8 machine, I needed to keep the default gateway route through eth0, even though both eth0 and eth1 were receiving DHCP. It took a suprisingly long time to Google that in CentOS, you can simply use GATEWAYDEV=eth0 in /etc/sysconfig/network rather than mucking with /etc/sysconfig/network-scripts/, etc.

It is a little annoying that although CentOS will pick up the hostname from the first dhcp upped interface (eth0 in this case), it will set the default route through the last dhcp upped interface (eth1 in this case).
