Does anyone know how to do this? I want mutilple ftp servers all on port 21 but with different subdomains. e.g. ftp://mydomain.com:21 - ftp://mydomain.com:21 and ftp://mysub1.mydomain.com:21 - ftp://mysub1.mydomain.com:21 .

I can't find anything that tell me how to get this done.

For http, you can add headers, but how do you get the same effect with ftp on IIS?

That would work if they were on different servers. I want them on the same server... so they have the same IP. DNS only resolves IP addresses. The issue has to do with IIS and it's FTP server.

I must be missing something somewhere, because this seems so trivial. It would be a really lame oversight if IIS couldn't handle such a simple thing.

On second server, I use Red Hat linux and Apache (no asp.net here...) and it works like this:

 - In a control panel, create a new subdomain (always using dns)
 - The subdomain name is a folder, so if the subdomain is test.yoursite.net then the folder on the server is like /test/

I'm sure it must be in dns, since you're using a subdomain on port 21... If not, I dont know!

Ok - it didn't work... The DNS stuff was already all done - so no worries there.

I set up the folder the same as the subdomain, but it didn't work.

Is IIS that lame? or am I missing something.

you said... "That would work if they were on different servers. I want them on the same server... so they have the same IP. DNS only resolves IP addresses. The issue has to do with IIS and it's FTP server."

It is impossible to bind port 21 more than once on a same IP address... unless you use two network card with different ip address and use DNS to resolve your domain and subdomain... You can only make use of this IIS feature if you use Window 2000 server (not professional version)
OR...
if you still want to use the same ip number, you have to have DNS too to help you....

try this configuration....
(Im sure that there is only one FTP server that is bound to port 21 on one network card right?...)
In your Internet Information Services, go to your ftp server properties under you computer/server name... on FTP server tab, in Identification frame set IP address as '[All unassigned]"

I think this is nothing to do with IIS's ftp server only thing that maybe you missed some configurations...

Thanks

It kind of doesn't have to do with binding to port 21 - it's more related to the FTP protocol. e.g. Win2K server let's you have multiple web sites, given that they all have DNS records, as long as you use HTTP headers. They all are bound to the same port, but are properly redirected. FTP doesn't have any sort of mechanism like that though it seems.

The server is setup properly, and since there is only 1 NIC, whether they IP address is assigned or not won't make a difference.

I've looked and looked and looked, and I don't think this is MS dropping the ball... I'm more inclined to think that it is a limitation of the FTP protocol instead. I could be wrong, but I'm losing my mind trying to get this to work. I've tried everything mentioned above already with no success.

The ONLY thing that I can think of is to:

1. Set up local user accounts with the same name as the subdomains.
2. Create directories for the users.
3. Remove write permissions for all users on all 'subdomain' directories.

e.g. Directory structure:

• FTPROOT (mydomain.com)
• downloads (downloads.mydomain.com)
• something (something.mydomain.com)
• blah (blah.mydomain.com)

I had thought of doing things that way before, but I really don't want to do it like that. Oh well... such is life I suppose...

My bad. I screwed up your suggesstion and mixed it with what I wanted to happen. What is needed is for the subdomain/subfolder to be under the root ftp folder.

let's use external dns.. maybe you can try free (redirector) dns (i.e cjb.net), create 2 accounts for those two ftp url.. if it works.. maybe microsoft's dns (or active directory) is actually... sucksssssssss.. :)

* dont use dns integrates with active directory... in my case i use stand alone dns services (no active directory)...
