I am getting trouble to access some web sites without any error messages. It seems some packets being loss. I would like to identify the problem to fix it as soon as possible. The tool I used is not the classic traceroute because I can ping to the web site successfully. ICMP is not enough. I guess that the problem should be only effective to TCP or something in higher layer.

I have an application running on local area network. It will usually update itself by checking the most up-to-date files from network folder shared from a server. My problem is that the shared folder are restricted access right by user and password. That means I have to connect to that shared folder prior to running the application. It is unaccepted by someone who can force me to find better solution. And now I found below code.

Apache HTTP Server comes with a handy mod_status for monitoring current status and performance of itself. However, mod_status doesn't show the performance in the past. I like the historical data because it would help me to find problem occured since last crash.

In some cases, you may want to use your DSL router as a modem or you have a DSL modem and a linux box. It occurs to me right now since ZyXEL Prestige 650R-31 is not quite good for large network and its routing policy doesn't enable nat loopback by default. I managed to enable that feature via cron by the linux box but it seems sometimes not work properly. So I decided to switch it back to bridging mode (modem) through PPPoE. Setting up PPPoE in Ubuntu is very easy.

I have found a digg entry about OpenID. This is not my first time for OpenID but according to my current work, it sounds very interesting technology. So I would like to try it out by myself in action. This post is to describe my thought of choosing the right OpenID Server for me.

I'm going to upgrade my laptop from Dapper to Edgy very soon. One common procedure is to upgrade all packages to the latest versions before upgrading the whole distribution. Then I found something weird because I usually used graphical tools to upgrade packages but now I run apt-get as follow.

sudo apt-get update
sudo apt-get upgrade
