Setting up LAMP on Centos 6.3 with SuExec and FastCGI for performance

Use this script to help create a LAMP server with FastCGI, SuExec and a simple script to setup WordPress Virtual hosts.

Lync 2010 with WildCard Certificates

Lync 2010, is a terrific piece of software that allows for simple, effective collaboration for all sizes of businesses. Unfortunately,the architecture of the application is kludged together in a half baked form. What this also means that is that the Lync team decided to support “SAN” or “UCC” certificates so they can secure multiple domains with one certificate. However, they neglected to support wildcard certificates completely. This has been somewhat resolved with the latest Cumulative Update 6 (CU6), but still a nightmare to get going.

Even with this blog post, you may find it a nightmare to get it to work. Here are the steps that worked for me. This is for a 3 server setup, two front ends, and one edge.

1) Get a good wildcard cert. The EssentialSSL Wildcard from Comodo worked for me. The PositiveSSL did NOT.

2) Get the thumbprint of the SSL.

3) Install the certificate on all the machines. Make sure its in the My Computer sectionof the Certificate Manager

4) Open the Lync Powershell.

5) For the front end pools, enter the following command
Set-CSCertificate -Type Default,WebServicesInternal,WebServicesExternal -Thumbprint <thumbprint> -Verbose -Confirm:$false -Report c:\temp\test.html

6) For the edge pools, enter the following command
Set-CSCertificate -Type AccessEdgeExternal,DataEdgeExternal,AudioVideoAuthentication -Thumbprint <thumbprint> -Verbose -Confirm:$false -Report "c:\temp\test.html"

7) On all machines, create the reg dword key
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL]
"Sendtrustedissuerlist"=dword:00000000

Reboot. Check your event logs to see if it took. When I used the PositiveSSL Wildcard, it did not work -the system simply didn’t trust it. The EssentialSSL worked fine.

Lync 2010 Hanging up after call connected

Hello, a quick post. Over the past few weeks, I noticed that Lync calls were hanging up on me for no apparent reason. After it hung up on me with a client that needed help right away, I got frustrated and tried to figure out what the problem was.

After looking around, I found the issue to be multiple ip’s on my workstation that were un-routable. I had added static IP’s to my workstation to configure some routers and switches, and didn’t remove them after I was done.

Apparently, Lync tries the other IP’s if they think its going to work better – in the process, it hangs up the call when it tries to connect to one of the non routable ip’s.

So, if you have having an issue with Lync which causes a call to connect, and then get disconnected after 5-10 seconds – look at your ip configuration.

Possibly related to Call Admission Control and Media Bypass.
