I have a hub, with some computers plugged into it, and a cable modem. All of the computers except one have statically-configured addresses. The remaining computer runs a DHCP client, to get an IP address from the cable modem. It routes and NATs for the other boxes.
The router also runs a DHCP server, which I cannot disable. Is there any way that DHCP requests from the internet could reach it, affecting other customers of my ISP?
I already have an apache webserver set up, and it is working for PHP.
It has no static VirtualHosts set up, and dynamically routes all requests.
A request for http://example.com/ would be served from the document root /var/www/example.com (VirtualDocumentRoot), and a request for http://example.com/~user/ would be served from the document root /home/user/public_html (mod_userdir). The latter works no matter what the domain.
I would like to be able to serve Ruby on Rails applications, from the root of a document root, or from a subdirectory, using Phusion Passenger. However, it requires me to add some lines to the <VirtualHost> directive, which obviously isn't there.
I would prefer a solution that does not require root to deploy an application, but this is not critical. I also do not mind a solution that does not use Passenger, if I have the same ease of deployment.
How can I export a Kerberos keytab with a given password, so I can use it to authenticate passwordlessly with MIT KfW, while still being able to authenticate with a password elsewhere? If it matters due to enctype issues or something like that, the KDC is MIT.
Thanks
