Apache: Setting up a simple reverse proxy

Hello,

this post describes how to setup a reverse proxy for a host. All http requests to host reverseproxy.domain.org should deliver the content of www.domain.org at Port 8080.

First you have to enable the requiered modules in httpd.conf


LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so

Then insert a virtual host directive:


<VirtualHost *>
    ServerName reverseproxy.domain.org
    ProxyRequests off
    ProxyPreserveHost On
    ProxyPass / http://www.domain.org:8080/
    ProxyPassReverse / http://www.domain.org:8080/
</VirtualHost>

That’s it.

Powershell: Control Excel remotely

Hi,

I often have to collect some data and fill out some excel lists with those. Here are a few examples how to control Excel using the COM object with powershell.

VMware: Computer Account is disabled after deploying Windows Clients

Hello,

last week I had to deploy 25virtual Windows (XP) Clients an on VMware ESX Cluster. One of the requirements was that the clients must be member of a Windows Active Directory.

After setting up vCenter (copy sysprep) I installed a reference Windows XP vm, convert them to a template and defined a Customization Specification like this:

Initial Customization Specification

Initial Customization Specification

During the cloning process, by using the template with the recently created custom spec, the domain join always fails and the Computer Account was disabled at each try.

Ok, now I tried modify some parameter of the Custom Specification:

  • Changing the Domain from fqdn to the NetBIOS Domain “SUB”
  • Altered the Username to SUB\joinuser or joinuser@SUB or joinuser@sub.domain.org
