First, download the file from http://ftp.yz.yamagata-u.ac.jp/pub/network/net-snmp/

Now, tar the file, using this command (this example use ver 5.1, but you may use it for other version).

#tar -zxvf net-snmp-5.1.4.tar.gz

#cd net-snmp-5.1.4

# ./configure –prefix=/usr/local/snmp

#make

#make install

# ee /usr/local/snmp/share/snmp/snmpd.conf

com2sec public HOSTNAME public

group public v1 public

group public v2c public

group public usm public

access public “” any noauth exact all none none

**** Change the HOSTNAME (or IP ADDRESS)***

After snmpd.conf created, now actiavate snmp using commands below:

# /usr/local/snmp/sbin/snmpd -c /usr/local/snmp/share/snmp/snmpd.conf

checking whether snmp daemon runs flawlessly?

# /usr/local/snmp/bin/snmpwalk -v 1 -c public HOSTNAME system

change the HOSTNAME with a hostname or IP Address you entered on “snmpd.conf”, if it works, you’ll get a message like this.

There are many tutorials on this subject, but you can use the CLI (command line interface) that is easier and simpler. For Java 5, you jsut have to execute:

sudo apt-get install sun-java5-jdk

And for java6, you can execute

sudo apt-get install sun-java6-jdk

Simple isn’t it. You can also Update the JDK (java development kit) by executing.

sudo update-alternatives –config java

I did finding those command beneficial when i was installing OpenBravo. An open source Point of Sales software that is cross platform build with Java.

As you know, open suse 11 is already released. Now i would like to try to install java on OpenSuse. Here’s the steps:

1. Download Java, you can find it from here.
2. Open command line interface on your linux (eg: konsole, xterm etc) and change yourself as root.
3. Copy the jdk you have downloaded to /opt directory # cp jdk-version-linux-i586.bin /opt
4. Chmod the file so you could execute it.# chmod +x /opt/jdk-version-linux-i586.bin
5. Execute the installer. ./opt/jdk-version-linux-i586.bin

If you found mistakes on your installation, probably you should remove the as-is /usr/bin/java by executing # rm /usr/bin/java. After that force the path by executing # ln -s /opt/jdk1.6.0_05/bin/java /usr/bin/java.

I have written a tutorial on how to create an ISO using visual software before, And i have just browse online knowing that there is a tool on Linux that let you copy DVD or CD as an ISO image so that you could copy CD or DVD movie by only utilizing command line on Linux. Yes, it’s using cat statement.

Just execute:

cat /dev/dvdrw > ~/iso_files.iso

After you execute command above, linux will copy the cd as ISO files. You have to note that the /dev/dvdrw path might be different on your computer, for example it may be /dev/cdrom.

After you have created a perfect iSO, then you could utilize any iso burning softwares to burn the iso….
