Install DHCP Server

By depratama
Last week i need to install dhcp on my server. My server use Linux Ubuntu 8.04 as an operating system. These are the steps :

1. Install DHCP3 Server
sudo apt-get install dhcp3-server

2. Edit Configuration of DHCP
sudo nano /etc/dhcp3/dhcpd.conf

This is the configuration of /etc/dhcpd.conf

# Sample /etc/dhcpd.conf
# (add your comments here)
default-lease-time 600;
max-lease-time 7200;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.1.255;
option routers 192.168.1.254;
option domain-name-servers 192.168.1.1, 192.168.1.2;
option domain-name "mydomain.example";

subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.10 192.168.1.100;
range 192.168.1.150 192.168.1.200;
}

Save this configuration using Ctrl+O and Exit using Ctrl+X. This configuration will result in the DHCP server giving a client an IP address from the range 192.168.1.10-192.168.1.100 or 192.168.1.150-192.168.1.200. It will lease an IP address for 600 seconds if the client doesn't ask for a specific time frame. Otherwise the maximum (allowed) lease will be 7200 seconds. The server will also "advise" the client that it should use 255.255.255.0 as its subnet mask, 192.168.1.255 as its broadcast address, 192.168.1.254 as the router/gateway and 192.168.1.1 and 192.168.1.2 as its DNS servers.

3. Restart DHCP
sudo /etc/init.d/dhcp3-server restart

4. Finish

Extend a LVM partition after increasing its virtual disk on Virtualbox

By depratama
No Linux machine at work? the easy way could be to simply install Virtualbox in one of the PC, create a VDI and install Ubuntu 14.04 in it. But the day will come when you need more space! Here is how to resize it: Resize Virtualbox VDI Open Virtualbox, make sure to shutdown your virtual machine. Then open a terminal (here windows): 1 2 3 4 cd “ C : \ Program Files \ Oracle \ VirtualBox ” VBoxManage list vms VBoxManage clonehd uuid 0000000000000000 backup . vdi VBoxManage modifyhd uuid 0000000000000000 -- resize 204800 This is the Virtualbox official manual  of available commands. And  this is a website  to convert Gb into Mb (–resize takes Mb as input, 200Gb = 204800Mb). Boot Gparted to resize the partition After a default install of Ubuntu Server on one physical disk, you will have a SWAP partition, and then an extended partition in which you’ll have your LVM partition (So 3 partitions).  Download Gparted  .iso,...

By depratama
One day when i open a document in Ms. Word 2003, I get the message “ This document could not be registered. It will not be possible to create links from other documents to this document .” After searching using google.com and open some website, i have one solution. It’s only one maybe two step that i have to do. I open my services panel and activated my DCOM Server Process Launcher . And, it works, the message no longer show again when i open my document using word 2003. That’s all. I hope it works to you too, if you have same problem. Nb: Open services panel, just open Run (Start–> Run) and type services.msc then Enter .
