Hosting an external subdomain & DNA Manager

Whoever owns the main domain, needs to setup the subdomain record. That record can point to anywhere, including your LINODE Public IP. Then you setup a Virtual Host for that Subdomain.

First, have your friend add the DNS entry with his provider so the desired domain name resolves to your server's IP address.

Second, configure your server (as appropriate for the web server and/or application you're using) to service that domain name. For a web server, that would be a standard "virtual host" configuration.

The first bit takes care of resolving the name people use so that they contact your server, and the second takes care that your server does the right thing when those people access it.

PS: Under some circumstances, and depending on the capabilities of your friend's DNS provider, it is theoretically possible for your friend to delegate the actual DNS administration for the subdomain to you (at which point you could do the first part yourself through whatever DNS provider you use, or Linode's own DNS manager), but that can get complicated and for simply acting as the host for a single domain name is unlikely to be needed/desired.

Thanks you very much for the assistance on this. I truly appreciate it.

I almost have this working but for one small thing: The external subdomain points to its root folder at Linode just fine, so If I type http://subdomain.domain.com , it happily goes to to root. However, any directory/file below that will not work unless I include the root directory into url path again:

subdomain.domain.com-> DocumentRoot is /var/www/topdirectory. Inside I have a directory and a file: /var/www/topdirectory/somedirectory/index.html

if I visit http://subdomain.domain.com, the root at /var/www/topdirectory loads fine.

if I go to http://subdomain.domain.com/somedirectory/index.html I get an error (URL not found)

if I go to http://subdomain.domain.com/topdirectory/somedirectory/index.html I get no error, but the root path should not be there.

I know this is gonna be a Rewrite module thing but I cannot figure out what. I am guessing I need to write a rewrite rules on the apache file OR make an .htaccess file for that directory.

Any chance you your may have a a hint as of what I need to do?
