LDAP Server

OpenLDAPFirst you start with a mailserver, then you decide you need your own webserver. But what to do with a webserver if you have no FTP server? Things evolve…and then suddenly you discover that something like an addressbook server exists! You need that for your mailserver! Okay, LDAP is not only to be used as an addressbook server, but just like the rest you have to start somewhere.

Ofcourse I choose an open source LDAP server, OpenLDAP. Installation was pretty easy and straight forward, but configuring LDAP seems to be not something that you do in a few minutes. I currently have a pilot running, testing to see if everything works fine.

I have tested a lot of schema’s as I wanted OpenLDAP to be compatible with Outlook. I have forgotten about that idea…to hard! But I really don’t understand why there is no proper schema that makes OpenLDAP fully Outlook compatible? Many people use Outlook, more than X500’s, etc… Perhaps, I am doing something wrong, please let me know!

Apache DSFor administrating I am using Apache DS. Nice tool! I am still thinking of installing a webadministration tool, but first I want to make sure my LDAP survives the pilot phase. Currenly it’s running on my Outlook clients internally and my webmail client. It all works fine this far!

Who stumbled upon my Nabaztag?

Internet is such a nice medium, got an email from the Nabaztag Blog, asking me if linking is a good idea. Sure! Best idea there is, linking is cool, linking is the internet 🙂 Some time ago I built an Nabaztag-Ear-Mover. A simple PHP-script that allows you to move the ears of any Nabaztag in the world. At the Nabaztag Blog you can read much more about the cool features and possibilities of Nabazag!

Webserver efficiency improved

It’s always a matter of balancing if you use old equipment to run your server, but thanks to the Apaches, PHPs and MySQLs of this world it can be done. It took me a while to find out where the biggest inefficiencies were on the server. The help of Apache Server monitor was very usefull here. One of the things that improved efficiency was telling Googlebot what to index and what not to index. Fortunatly Googlebot (the spideringtool of Google) visits me up to 100 times a day so it’s important to tell Google what to know. I use robots.txt files to let Google know what is to be done at a certain site.

Advanced User Statistics

My job is marketing professional for Netherlands largest software developer, Exact Software. That’s why I probably like visitor statistics and other data gathering tools so much. This blogs seems to be a great way to test these things. I love new technologies.

This blog is now running the following tools
UserOnline, see who is currently online
GeoTrack, see in detail the location of visitors
PHPMyVisits, advanced statistics for bigger sites
Webalizer, a standard statistics tool

Further more I have extended the number of websites and blogs this blog automatically notifies whenever I make an entry in the blog. Currently the total is 32 other sites and blogs. It’s just a number, the strength is in the possibility. Perhaps in my next blog I will tell you a little bit more about the marketing data gathering tools 😉

UserOnline

My newest addition to my weblog is to show which users are currently on my site. I love dynamic content and to see what is actually happening to my blog. A live example of the current visitor, yes you!, is below here. Also a links, top left, is displaying how many users are currently online, and you can browse it yourself by clicking the link in the Page section. In a later stage I will also integrate this tool with my website www.eppenga.com. Thanks go out to Lester Chan who developed this nice gadget.

Samurize Monitor

Server InformationSamurize is a freeware tool that enables you to monitor your computer. Combined with other freeware programs it can monitor almost anything you like. It’s also used to create fancy desktops and give you direct information about your surrounding (like weather, tv programs, etc).

 In my case I use it to monitor my server. It monitors general things like the CPU, memory, harddrives and network data. To the right you see what is currently monitored. This is a live image, please also check te date and time. Samurize also features an extension called Samurize server which enables you to create images like this, but also more advanced things like XML and the possibility to connect a Samurize client.

The tool that I use in combination with Samurize is Speedfan. Speedfan monitors various temperatures and ofcourse the speed of your fan(s). These programs are all freeware and are definatly worth exploring if you digg this!

Home network

Home networkI proudly present my own little home network. It features two wireless networks, a cabled network, PSTN (analogue) and voip telephony. Why two wireless networks? Because the server is on a single wireless network to keep the speed to my server at a high level. Wifi networks are hub based, that means that they share the connection speed, the more connections are made. It wasn’t an option to connect the server to the cable network because of esthetical reasons.

Personally I still don’t trust voip telephony to be on 100% of the time so that’s why we have two separate types of telephony. It’s a fully seperated system, voip can fail while analogue is still online. The voip system is a true voip system, no PCs or servers are involved to keep it running.
