Question

Multiple Web sites on Citrix WI and CSG

Asked by: ckstanley12

Is it possible to host another SSL enabled website on the same server that hosts Citrix Web Interface and Citrix Secure Gateway?

Here's the setup:  Single W2K3/IIS6 server in the DMZ.  It's currently running Citrix WI 5.0 (in the default web site) and Secure Gateway 3.1.  I want to run another SSL protected website on that same server.  I have a wildcard SSL certificate.

Approach #1 - I tried assigning separate IP addresses to the two websites, but when I did that I got the error "The process cannot access the file because it is being used by another process".  When I did the netstat -ano, it indicated that port 443 was being used by ctxsgsvc.  Trying to add the ListenOnlyList in the registry (according to http://support.microsoft.com/kb/890015) didn't work.

Approach #2 - Immediately after trying the above, I tried to disable socket pooling according to http://support.microsoft.com/kb/813368/en-us.  That didn't work either.

Approach #3 - I tried assigning host headers to each of the web sites and using the adsutil.vbs script described here:  http://lanestechblog.blogspot.com/2008/03/creating-self-signed-wildcard-ssl.html.  This only resulted in both the default web site (Citrix) and my second web site not being able to start.  If I changed the ports on the 2nd web site, it would start, but not the default web site.

At this point, I rolled back the system state on the server in order to get my Citrix to work again.  After a bit more testing today, I've made the following observations:

 - Citrix Web Interface/Secure Gateway does not work if I assign it a specific IP address through the configuration wizard.  It would only work if I told it to monitor all IP v4 addresses.

 - Citrix Web Interface/Secure Gateway does not work if I add a host header to the IIS config of the default gateway

So, I'm either missing something in one of my approaches above, or Citrix Web Interface/Secure Gateway commandeers SSL for the entire server and I am not going to be able to run a second SSL secured web site on that same server.

Any suggestions?

I am in the middle of setting one of these up now actually; I will let you know if/when I succeed.

Citrix gets wonky when you try goofing with the SSL setup. It uses 443 and forwards to 444 if memory serves...I've screwed with a similar setup it and brought the entire farm down.
Usually you want the secure gateway dedicated to Citrix only.

 

by: BLipmanPosted on 2009-11-05 at 15:42:24ID: 25755344

Yeah, it is tricky, the server in question is now configured to have CSG run only on the IP address it should be.  The trick will be to see if I can get the other site to use the other IP and not complain about anything.  It is an uphill battle for sure.  

 

by: BLipmanPosted on 2009-11-09 at 14:07:52ID: 25780641

Ok, I have a working environment with a CSG/WI site on the main IP and only bound to that IP.  WI is on 80 and 444, CSG is on 443.  The second IP runs a DotNetNuke site running on 80 and 443.  This is possible.  Can you get both sites to start once you restrict CSG to the single IP and set the other site to 443?

 

by: ckstanley12Posted on 2009-11-09 at 15:07:12ID: 25781055

Thanks.  I think I tried that at one point, but I will try it again after hours tonight.  I'll update this post when I'm done.  Did you need to do anything funky like running the httpcfg or the adsutil utiliies or setting the ListenOnlyList in the registry?  From what I understand in your post, I just need to run the Secure Gateway Configuration Wizard.  Is that right?

 

by: ckstanley12Posted on 2009-11-09 at 15:08:10ID: 25781061

Also, BLipman, what OS version are you running on that server?

 

by: BLipmanPosted on 2009-11-09 at 15:33:57ID: 25781205

Nope, nothing strange.  I wasn't the one doing the CSG part, I was only involved in dropping our custom DNN site in so the other guy may have needed to do some unnatural things.  
The server is running 2008, 32-bit.  

 

by: ckstanley12Posted on 2009-11-13 at 10:54:59ID: 25816646

The server was down for a couple days with an unrelated hardware problem, so I haven't been able to try this yet.  Hope to be able to do this over the weekend or early next week.  Will post my results then.

 

by: ckstanley12Posted on 2009-12-17 at 09:36:35ID: 31650794

I couldn't get this to work, so I gave up and set up a new server to host my other web site.  Had the specific steps been listed on how BLipman got it working, and had those steps worked for my situation, this post would have a much different result and rating.
