LDAP on Abel World

LDAP linux configuration and install from source

Sun, 11 Jan 2015 21:37:35 +0200

Hi, if you want to configure LDAP (OpenLDAP) properly and you have never done it, I advise you to read a lot of

LDAP tree

nonsense out there that people write on blogs like mine, before actually trying. After reading a lot of that the you can try, and let me tell you a secret, the best documentation is the one that they provide on their own website, just that sometimes that one is a bit complex to understand.

Well fist the fist, my LDAP version 2.4 never worked installing from repositories on Debian 7. How unable am I or how silly… I don’t know. Bot it did not work as it use to do with earlier versions. I was unable to set the user, password, domain and those initial things using the installer package.deb and dpkg-reconfigure. So I decided immediately that if I am losing the power of having a repository because of this nonsense, then I do not need them any more. I am going to compile the package myself from source. I tried so… but I struggled with the ./configure options. I could not fins the proper ones. and this error report thread gave me the clue to be able to follow the LDAP manual.

After reading this manual I ended up with a file that contains this:

Network segmentation for business

Thu, 08 Jan 2015 19:55:09 +0200

Network segmentation was created to help dividing network from each other. Wikipedia defines it as: “Network

Network Segmentetion

segmentation in computer networking is the act or profession of splitting a computer network into sub-networks, each being a network segment or network layer. Advantages of such splitting are primarily for boosting performance and improving security.”

The applications of this are infinite in now a days business world. Let me just explain a little about my customer particular case.

I decided to write this Network segmentation post due to our last client. He is a hotel owner. The hotel has a lot of rooms. They had a network of a few staff computers plus all the customers computers. The customers access the network using WiFi. Just to serve as an example the customers were on the same network as the accounting computer. That is not a good idea. For instance the day that I was deploying the server at the hotel. I had to cut the network for a few minutes. A customer came to complain and guess what. He was an IT guy. He came saying to me things like the IP address from today is different from the one I had yesterday. I did an NSLOOKUP and it says bla,bla,bla. This guy turned to be a really nice guy, but not everyone has a good heart and intentions.

So because of an incident the owner called me to find a solution. He wanted a few more things. Here is part of a presentation we did for him.

Linux Server Classes (Introduction)

Linux Server Classes; About this group of materials.

Linux Versions with Tux

I have started this post to bring Linux classes to any one in Gaborone, Botswana. Also you can access and use this materials any where else in the world. The only conditions is that you have to be willing to learn new and useful stuff from the free software movement. This Linux skill sharing was done for the ICT staff in Princess Marina Hospital in Gaborone, Botswana. The main objective was to socialize the Linux knowledge. These skill sharing classes are not part of any certified course. They are just the product of the personal experiences of a Linux and windows network administrator. Linux is currently being used at the hospital in most of the servers and a few workstations. But the course is thought as a General introduction to networking using GNU Linux Debian.
