Installing Terratec S7 on 64-bit Windows 8.1

May 24, 2017

I got myself a Terratec S7 because my existing Cynergy S2 card started to show problems, and the situation is not resolved yet, mainly because the S7 does not appear to control the dish as it should in the PC I want it to run.

To figure out where exactly the problem is, I took the S7 and tried to install everything on a separate laptop, not contaminated by previous installations of any TV software 😉

I got the latest drivers for Windows 8.1, and of course DVBViewer, which superseded Terratec Home Cinema, well-known from the S2 installation.

I installed the drivers, but did not immediately notice that the installation had failed. Only when DVBViewer presented an empty list of supported hardware, and after installing the drivers again, I realized the failure (there is no visual clue as to whether installation was successful or not, you actually have to *read* *text* 😉 ).

The output of the Windows Error Report (accessible from the error entry in the Event Log) listed an error code E0000247

FriendlyEventName=Die Treibersoftware konnte nicht installiert werden.

which hints at a certificate validation error (hint, hint).

The Device Install Log at C:\Windows\Inf\ was also rather clear on the issue:

sig: Key = terratec_s7.inf

Since 64-bit Windows requires device drivers to be signed, this seemed to be a show stopper. However, you can disable signature verification by typing (in admin mode)

bcdedit /set testsigning on

which fortunately worked on my laptop.

After reboot, I was able to install the drivers, and Windows even is so nice as to warn you if you install unsigned drivers

terratec signed driver

(There is probably an alternative method by extracting certificates from the installer’s .cat files, but I didn’t have to try, so I can’t tell.)

Starting up DVBViewer again, it immediately recognized the S7, and a range scan found several hundred channels fine. I switched to a couple of channels that I also had on my TV, but there was no picture.

Forum talk mentions this issue, along with LAV filters, which I had come across earlier clicking through the files of the Home Cinema download page. So I downloaded TERRATEC_Home_Cinema_Codec_Patch.exe from there, installed it, and finally got a TV on my laptop.


Adding Dropdown Arrow for Chosen Plugin in Multiselect Mode

April 2, 2017

I use the jQuery Chosen plugin in a web application, and recently got the request to display a dropdown arrow in multiselect mode.

I found an answer on SO regarding styling of the dropdown arrow, but that covered only singleselect mode. At least a starting point 😉

Within minutes, I had a CSS-only solution for this particular problem:

<style type="text/css">
.chosen-container-multi.chosen-container .chosen-choices::after {
    background: url(@Url.Content("~/Content/chosen-sprite.png")) no-repeat 3px 4px;
    width: 16px;
    height: 100%;
    content: " ";
    position: absolute;
    right: 0;
    background-color: lightgray;

(Note that this is an ASP.Net MVC application, and @Url.Content() computes the URL relative to application root.)

Only after I solved this, I found that there is a closed (and unresolved) issue on github from 2011, with comments up to 2016, but no solution to a valid feature request…

Emoticon Selection in ASP.Net MVC

March 30, 2017

I had to implement a good/bad/neutral selection UI in an ASP.Net MVC application.

This simple task turned out to be rather cumbersome, given different browsers implementing different things differently, and the MVC framework restricting access to generated markup.

I first thought about a DropDownList (i.e.) rendering a set of emoji, only to find

  • you cannot pass a C# emoji as SelectListItem.Text
new SelectListItem {Text = "\u1F60A" }
  • you cannot add the emoji HTML entity 😊 astext (at least not in Chrome)
  • you cannot add a @class parameter to SelectListItem
  • you cannot add a background-image:url() definition to an
  • you cannot add HTML tags inside an(


However, I found code to overcome the limitations of SelectListItem, either by copying and extending code from the MS MVC framework, or by XML manipulation of the built-in HTML generator.

Maybe the dropdown list was just the wrong path to follow, so I searched for ways to style radiobuttons, and found this nice demo on codepen.

I modified the demo to fit my needs, and voilà, here’s my first codepen:

A radiobutton-based emoji selector

Update: Apparently, IE does not render an <img> inside a <label> clickable, unless you specify pointer-events: none.

Using PowerShell to find IIS Sites without https enabled

March 21, 2017

To retrieve all certificates registered in IIS, run this command in PowerShell Administrator mode (source)

import-module WebAdministration
get-childitem iis:SslBindings

To retrieve the bindings (i.e. http and https properties) of IIS sites, run (source)

import-module WebAdministration
get-website | select name,id,state, physicalpath,
@{n="Bindings"; e= { ($_.bindings | select -expa collection) -join ';' }}

I used the last code snippet to find the IIS sites without https / SSL certificate:

import-module WebAdministration 
get-website | where {$_.State -eq "Started"} | 
select name, 
  @{n="Bindings"; e= { ($_.bindings | select -expa collection) -join ';' }} | 
where {$_.Bindings -notmatch "ssl" } 

There is also a nice script finding IIS certificates and whether they are used in an IIS site or not.

Adding SSL Wildcard Certificates to IIS Webs

March 21, 2017

As web browsers start to issue warnings on plain http websites if you are asked to input username/password, it’s time to add SSL certificates even on dev/test servers. We can expect more aggressive warnings in the future 😉

Apparently there is a way to create a self-signed certificate built into IIS (screenshot from Windows Server 2008)

iis create certificate

but this seems to create cerficates only for the host name, not for any domain hosted on the machine.

Back to square one, start up a current Linux machine, and make sure your openssl is newer than version 1.0.1f. (Remember Heartbeed?).

The instructions I found to create self-signed certificates are nearly identical (source, source, source)

openssl genrsa 2048 > my-host.key
openssl req -new -x509 -nodes -sha1 -days 3650 -key my-host.key > my-host.cert
# make sure Common Name starts with "*.", e.g. *
openssl x509 -noout -fingerprint -text < my-host.cert >
cat my-host.cert my-host.key > my-host.pem

For use in IIS, you need to create a .pfx from these certificate files:

openssl pkcs12 -inkey my-host.pem -in my-host.cert -export -out my-host.pfx

Copy the .pfx to your IIS machine.

In IIS Manager, select “Server Certificates” on the server node, click “Import…” to import the .pfx certificate.

Start up mmc, “File”, “Add/Remove Snap-in”, select “Certificates”, “Add”, “Computer account”, “Finish”, “OK”, (this click orgy shows you how important certificates were in 2008, as compared to Start/Administrative Tools/Data Sources (ODBC) 😉 ) and find the imported certificate(s) under

Console Root\Certificates\Personal\Certificates

Right-click each of them, select Properties, and make sure that the Friendly Name starts with “*.” for wild-card certificates. Otherwise, you cannot assign a host name for https web sites.

Back in IIS Manager, select each site you want to add https support, click Bindings, Add, select Type: https and select the wild-card SSL certificate. Only if the friendly name starts with *, you can/must set the site’s Host name. Click OK and you are done.

If you want your sites to redirect http to https automatically, make sure the Require SSL box is not checked in the site’s SSL Settings.

The minimal web.config to perform these redirects looks like this (source, source)

<?xml version="1.0" encoding="UTF-8"?>
        <rule name="Redirect-HTTP-HTTPS-IIS">
          <match url="(.*)" />
            <add input="{HTTPS}" pattern="^OFF$" ignoreCase="true" />
          <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" 
            redirectType="Permanent" />

Be aware that while these steps enable https for your IIS sites, self-signed certificates still require the users to explicitly accept the certificates in their browsers, which will raise an “Unknown issuer” warning at their first visit.

Update: There also seems to be a Powershell way to do it 😉

Installing AWStats on Windows Server 2012

March 7, 2017

To install AWStats on Windows, first download the current version from If you don’t have Perl on your machine, get Strawberry Perl for Windows, as ActivePerl requires an annual Business License for production use.

On the server, create a web directory and a data directory for awstats. Follow the steps in the AWStats Setup Guide.

To access the log files of a remote IIS, I created a read-only share on c:\inetpub\LogFiles, and had to run

icacls c:\inetpub\LogFiles /reset /t

to allow non-admin access to the IIS log files.

To get Strawberry Perl to run on IIS, follow this Installation Guide:

  • In the Web Server role, you need to have the CGI feature installed.
  • In IIS Administrator, create a web site or application hosting AWStats. In the site or application, you need to add a Script Map for *.pl executing
C:\path\to\perl.exe "%s" %s

Things should be running by now if you browse to


I noticed that the stats only included data from the installation date (IIS logs are configured to daily log files).

Answers on the internetz suggest to merge old log files using, a script that ships with awstats.

C:\awstats\tools>perl [all my log files] > merged.log

Replace the LogFile entry in your config file(s) to point to the merged log file


and run

perl -config=mySite

again after deleting the previously generated data files.

Unfortunately, the merged log only resulted in “dropped” and “corrupted” records:

Phase 1 : First bypass old records, searching new record...
Searching new records from beginning of log file...
Jumped lines in file: 0
Parsed lines in file: 30376
Found 16100 dropped records,
Found 0 comments,
Found 0 blank records,
Found 14276 corrupted records,
Found 0 old records,
Found 0 new qualified records.

This may be caused by a number of reasons, but it turned out that the merged log requires a specific LogFormat:

LogFormat="%time2 %other %method %url %query %other %logname %host %ua %code %other %other %other"

Finally, I created a batch file awstats.cmd to update all my statistics

net use z: \\host\LogFiles awstats /user:awstats
cd D:\wwwroot\awstats\wwwroot\cgi-bin
perl -update -config=mySite1
perl -update -config=mySite2
net use z: /delete

and created a scheduled task to automatically execute the script every day.
