I am trying to run wireshark in linux using sudo, but was told: i am not in the sudoer files. So I must edit this file to add my own user into this file. Steps as follows:
1. su to root: su-
2. open sudoers: visudo /etc/sudoers
3. add my user name: testuser ALL=(ALL) NOPASSWD:ALL
This lines means that the user "testuser" can execute from ALL terminals, acting as ALL (any) users, and run ALL (any) command.
The detail is in paper: http://www.go2linux.org/sudoers-how-to

In order to supports internationalization (I18N), on Tomcat some additional configuration is necessary. You must
ensure that Tomcat's URI encoding is set to UTF-8. You can do this by editing the Tomcat configuration file
conf/server.xml and adding URIEncoding=”UTF-8” to each connector element, as shown below:
<Connector port="8080"
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" debug="0"
acceptCount="100" connectionTimeout="20000"
disableUploadTimeout="true"
URIEncoding="UTF-8" />
And make sure you do this for every connectort.

I planned to install Roller in my centOS which need tomcat6. But centos5.3 has tomcat5 in it's yum. So I have to install tomcat6 using other way. I searched and found this good install guide in:
http://cloudservers.mosso.com/index.php/CentOS_-_Tomcat_6 ( or http://de0ris.blogspot.com/2008/08/installing-tomcat-6x-on-centos-5.html )
which give detail instructions. I choose some important part and paste here in case for late use.
1. install appache ant: (note: download and put the tar file in /usr/share first )
tar -xzf apache-ant-1.7.1-bin.tar.gz
2. install tomcat:(note: download and put the tar file in /usr/share first )
tar -xzf apache-tomcat-6.0.18.tar.gz
3. create a symbolic link for Ant so other applications can easily find
it. Be sure to select the correct version when you create your link.
ln -s /usr/share/apache-ant-1.7.1/bin/ant /usr/bin
4. set JAVA_HOME:
cd /usr/share/apache-tomcat-6.0.18/bin
vi catalina.sh
enter insert mode. Enter the following:
JAVA_HOME=/usr/java/jdk1.6.0_14
Test:
cd /usr/share/apache-tomcat-6.0.18/bin
./startup.sh
5.Automating atartup: Right now Tomcat will not start up on it's own so we need to create a startup script for this. To do this:
cd /etc/init.d
vi tomcat
Press i to enter insert mode and paste in the following:
#!/bin/bash
# chkconfig: 234 20 80
# description: Tomcat Server basic start/shutdown script
# processname: tomcat
JAVA_HOME=/usr/java/jdk1.6.0_14
export JAVA_HOME
TOMCAT_HOME=/usr/share/apache-tomcat-6.0.18/bin
START_TOMCAT=/usr/share/apache-tomcat-6.0.18/bin/startup.sh
STOP_TOMCAT=/usr/share/apache-tomcat-6.0.18/bin/shutdown.sh
start() {
echo -n "Starting tomcat: "
cd $TOMCAT_HOME
${START_TOMCAT}
echo "done."
}
stop() {
echo -n "Shutting down tomcat: "
cd $TOMCAT_HOME
${STOP_TOMCAT}
echo "done."
}
case "$1" in
start)
start
;;
stop)
stop
;;
restart)
stop
sleep 10
start
;;
*)
echo "Usage: $0 {start|stop|restart}"
esac
exit 0
Be sure to change the following items in the above file:
* JAVA_HOME path
* TOMCAT_HOME path
* START_TOMCAT path
* STOP_TOMCAT path
Once you have those changes made, save the file and quit.
Now we need to change the permissions on the file.
chmod 755 tomcat
We need to set the script to start with other system services and set the runlevels.
chkconfig --add tomcat
chkconfig --level 234 tomcat on
You can verify that it is listed by typing chkconfig --list tomcat.
tomcat 0:off 1:off 2:on 3:on 4:on 5:off 6:off
Test your shutdown and startup script.
sudo /sbin/service tomcat stop
sudo /sbin/service tomcat start
Tomcat 6 should now be installed under CentOS.

1.Agile model driven development(AMDD): focus on model
2.Extreme programmning: focus on full development life cycle.
3.Jconsole: c:\program files\java\jdk1.6.0_14\bin\jconsole, which could dectect the memory issue, class loading, garbage collection...

一看书名就知道又是一本通俗易懂的书。果不其然,而且比想象的更有意思(我想是简单的缘故吧)。
书里只是很简单的提及了一些网络的基本概念和运作原理,似乎各个方面都有覆盖,但是因为描述的很浅显,所以建议给:
1 想大致了解DNS,ARP,router等网络知识的人;
2 有闲但是对于网络感兴趣的人;
其实不错,无聊的时候翻翻,解闷!

centos
0. /sbin/ifconfig
1. mysql :
*remove: yum -y remove mysql mysql-server
*insatll: yum -y install mysql mysql-server
*check: chkconfig --list | grep mysql
*Set to Start on Boot:
chkconfig mysqld on
*start service:
service --status-all
service mysqld start
check: mysqladmin version
*setup root password:
mysqladmin -u root password ***(this is new password)
*run:
mysql -u root -p
*exit:
\q
*commands:ep t
show databases;
drop database ***;
2. Tomcat:
*install:
yum -y install tomcat5 tomcat5-webapps tomcat5-admin-webapps
*You can find these packages using
yum list available tomcat5*
or
yum search tomcat5
*Start:
service tomcat5 start
view: http://localhost:8080/.
*location:r
/usr/share/tomcat5 .
*setting:
"$CATALINA_HOME".
3. JDK:
* Originally, centOS only install jre. so we need install jdk by ourselves.
*To install from the command line:
$yum install
java-1.6.0-openjdk-devel
You can also install all
the OpenJDK 6 packages, including the API documentation, by
using the wildcard java-1.6.0-openjdk*.
*location: /usr/lib/jvm...
*check: java -version
