In part 2 of our Exchange 2010 tour I will show you how to configure Exchange 2010 to send and receive mail from the internet. In this tutorial I will use a trashdomain called “worldrallyforum.com”. The server is running Active Directory and Exchange 2010 as setup in my previous tutorial (part 1). The server is in DMZ and has the internal IP address 192.168.0.90.
In order to proceed you need a Microsoft Windows 2008 R2 server with Active Directory and Exchange 2010 installed (link).
Step 1. Open the Exchange Management Console. You can find it under Start > All Programs > Microsoft Exchange Server 2010 > Exchange Management Console.
Step 2. Expand Microsoft Exchange On-Premises. You will now be able to see a lot of categories to configure.
Step 3. Underneath Organization Configuration you will be able to find Hub Transport. A new window will appear with a few tabs. Hit “Accepted Domains”. Right-click inside this window and hit “New accepted domain”. A new wizard will appear. Enter a name, f.e. “wrf” and the Accepted Domain, “worldrallyforum.com” in my case. Hit new and finish.
Step 4. Underneath Organization Configuration, Hub Transport you will also be able to find a tab called “Send Connectors”. Right-click inside this window and hit “New send connector”. A new wizard will appear. Enter a name, f.e. “First send connector”, change the drop-down menu to “Internet”, hit next, hit Add.., in the Address field enter “*” and check “include all subdomains”, hit OK, hit next, if you want to use the MX record to route mail leave it like this, otherwise hit “Route mail through the following smart hosts”, Add.., check FQDN, enter the domain name (smtp.upcmail.nl in my example), hit OK, hit next, next, new, finish.
Step 5. The last step is to actually allow remote traffic inside the Exchange server by changing a policy. Underneath Server Configuration, Hub Transport, right-click “Default [hostname]”, properties, hit the “permissions groups” tab, check “Anonymous users” and hit OK.
Thats it! All you have to do now is adding new mailboxes underneath Recipient Configuration, Mailbox.
Changing the default domain name for e-mail addresses.
Imagine you have a lot of mailboxes and you want to change the e-mail addresses of them all at once. You can do this via the e-mail address policy int he Exchange Management Console.
Go to Organization Configuration, Hub Transport, E-mail Address Policies. Right-click into this field and hit “New E-mail Address Policy”. A new wizard appears. Enter a name, hit browse, select the OU that you want to change, hit OK, hit next, hit next, hit add, select “Select the accepted domain for the e-mail address”, hit browse, select the domain you want to add, hit OK, hit OK, hit next, hit next, hit new, hit finish.
Setting up your own Microsoft Exchange 2010 server is quite simple. You just need to download a few prerequisites that you can get from the PowerShell. In this tutorial I will show you how to install your own Microsoft Exchange 2010 server on Windows Server 2008 R2!
Before we can start, you’ll need to make sure that your new Exchange server is running in an Active Directory environment and that it’s part of the domain. It’s also advised to completely update your server to the latest software before starting the installation process.
In order to successfully complete the Exchange 2010 installation we need a few prerequisites.
First, install the 2007 Office System Converter: Microsoft Filter Pack. You can download it here.
Second, add a few Windows features that you can get from the PowerShell command. Start PowerShell via Start > All Programs > Accessories > Windows PowerShell. Run this program as system administrator.
A new window will open, enter the following command:
In case you wish to install a typical server including Client Access, Hub Transport and Mailbox roles, run the following command:
Once that is done, hit run to start the installation process. In the first window, uncheck all boxes and hit Agree. In the second window, hit Decline. The Orb installation will now start. Hit Next to get the Start menu button back and you are done!
Er zijn veel verschillende gratis antivirusprogramma’s. Heel veel zelfs. Maar wat is nu precies een antivirusprogramma en waarom gebruiken we het?

$ tar xzf teamspeak3-server_linux-amd64-126.96.36.199.tar.gz
Get into the new directory by typing:
$ cd teamspeak3-server_linux-amd64-188.8.131.52
Start the new TeamSpeak 3 server by running:
Your new TeamSpeak server will now start in foreground. Launch your TeamSpeak 3 client, enter the IP-address for your server and hit connect. After connecting you’ll get a massage about administrator privileges that have not yet been claimed. Go back to your terminal and copy the part AFTER “Token=”. Paste this into the “Use Privilege Key” input field.
You should now be administrator of your new TeamSpeak server!
In order to stop the running server, which is in foreground right now, hit CTRL+C. In order to run the server in the background, execute the following:
$ ./ts3server_startscript.sh start
You can now safely close your terminal without shutting the TeamSpeak server down.
In this (video)-tutorial I’ll show you how to setup your own OpenVPN access server in just a few minutes! OpenVPN is an open source software application that implements VPN techniques for creating secure point-to-point connections.
In order to proceed, you’ll need the following:
A basic installation of CentOS 5.8 (32- or 64-bit)
A dedicated or virtual machine
After the installation of CentOS, head over to the OpenVPN website at http://www.openvpn.net and go to “VPN Solution”. Now click on “Access Server Software Packages”.

Head over to your terminal and execute the following command:
