Safe web
by Mats Hellman on 04.Nov, 2009 under Apple, Life, Networking
This post is a little of topic from what I usually write but for me it’s something important so I hope you forgive me. In May 2009 I became a father to a little girl who means the world to me.
A post on the Cisco Portal blog got me thinking about security from a different point of view. Security at home. The internet has provided us with so much good. We can get information, access our bank and get news 24/7 . But it has it’s dark sides also. When I was young my parents knew that once I was home I was safe. I had my safe haven inside my parents house where no one could get to me.
The Internet with all it’s glory also opened a gateway to our homes for the predators. Following the news you read almost weekly about police shutting down large pedophile groups, and that’s a good thing. Law enforcement units are able to hunt them down using the networks. But just as the good guys use the networks to find them, the bad guys use the networks to share their sick and twisted materials.

Yesterday we setup our server to be able to handle the remote access requests. If you haven’t read the first part of this guide you can find it here. Today we will be taking a look at the next step.
Setting up SSL-VPN in an Windows Server 2008 environment
by Mats Hellman on 28.Oct, 2009 under Active Directory, Remote Access, VPN, Windows
In this 2 part series we will look at setting up SSL-VPN using Windows Server 2008. At the end on the next part you will be able to configure a Windows Vista or Windows 7 client to connect to the corporate network using SSL-VPN ( SSTP ). To test this scenario you need some previous knowledge of Windows Server System and Active Directory in particular. We will be using Active Directory to logon to VPN and control user access using it. If you, like me, don’t feel like testing in an production environment you can set this lab up in an Virtual PC or Virtual Server environment. I will not be going trough setting up Windows Server 2008 AD DS in this article. I expect you to have your domain up and running. To run this lab you will need the following
- Windows Server 2008 Enterprise running HEL-DC1
- AD DS
- DHCP
- DNS
- AD CS ( Certificate Services Enterprise CA)
- Windows Server 2008 Enterprise running HEL-NAT
- 2 network interfaces – External and internal
- Windows Vista Business Edition
- Service Pack 2
IP Subnetting made easy on TechRepublic
by Mats Hellman on 25.Oct, 2009 under Networking, Windows
If you’ve read my posts you’ve seen I’m trying to get my Microsoft Certified IT Professional status. This means getting reacquainted with things I went trough in school but have since forgot. One of these things is IP Subnetting. So I needed to find a good guide to refresh my memory. Googling I found there are many guides out there, but this one is mine (a little Full metal Jacket joke), but I found one on Techrepublic that was really in-depth and easy to follow. The writer, George Ou knows what he is talking about and makes following his writings easy. If you don’t have the time to read the whole article at least take a look at the part where he is using the Windows standard calculators AND function. Did you know about that?
Cisco ADSM and Windows Vista 64
by Mats Hellman on 24.Oct, 2009 under Cisco, Networking, Vista
I’m using Windows Vista 64-bit on my Windows desktop and launching Ciscos management software ADSM 6.0 I got an error saying
“ASDM is unable to continue loading. Click OK to exit from ASDM.
Unconnected sockets not implemented.”
ADSM was however launching on my Windows 7 64-bit laptop so I started looking for any other difference than the OS. ADSM is a Java application so starting there was only reasonable. I ran Java JRE 1.6 update 13 in the Vista machine and 1.6 update 7 in the Windows 7 laptop.
Downgrading the Java JRE to 1.6 update 7 solved the issue and ADSM is now launching without any problems. So if you’re having trouble getting the Cisco ADSM to launch, check and possibly downgrade your Java Runtime Environment.
