/usr/lib/vmware/bin/vmware-vmx: error while loading shared libraries

July 9, 2008 – 6:04 am

Due to the challenge for efficiency I decide to install vmware server on ubuntu server hardy heron 8.04

The installation process itself is smooth except this part :

/usr/lib/vmware/bin/vmware-vmx: error while loading shared libraries

vmware need a few shared libraries as requirement for register serial number. If I ignored it I’ll see repeating message that tell me that I’m unable to register vmware serial number.

Here’s little installation process:

root@dns:/home/edpteam# tar xvzf VMware-server-1.0.6-91891.tar.gz

root@dns:/home/edpteam# cd vmware-server-distrib/

Install Djbdns on Ubuntu Server

July 8, 2008 – 3:16 pm

I’m big fan of djbdns for its simplicity. After one of our server must change to vmware server and ubuntu chosen as main OS I still want to use djbdns for handling domain resolution.

Searching on internet guide for installing djbdns on ubuntu give me to this link. I try to follow it and it works

The different only for dnscache ip. I prefer to use lan ip for dnscache.

Here’s the adaptation of the guide :

Preparation :

apt-get install build-essential
add debian etch repository in /etc/apt/sources.list:

deb http://ftp2.de.debian.org/debian/ etch main contrib non-free

apt-get update

Install packages :

Install ucspi-tcp-src:
apt-get install ucspi-tcp-src
build-ucspi-tcp

Mounting Hard Disk on Ubuntu

July 7, 2008 – 3:38 pm

One of our server need to reconfigure. Install ubuntu server on it and will convert other hardisk for special purpose on vmware appliance.

In fact the server have 4 HD, 1 for system and 3 HD dedicated for virtual appliance.

This steps taken to format and mounting :

1. See current mount point and space .

2. See all attached HD and its file system.

root@ubuntuserver:/home/edpteam# fdisk -l

Disk /dev/sda: 146.8 GB, 146815737856 bytes

Partition table entries are not in disk order
root@ubuntuserver:/home/edpteam#

3. New HD layout scenario.

System in sda
Proxy in sdb -> /proxy
SandboxProgramming in sdc -> /probox
SandboxNetworkingÂ in sdd -> /netbox

4. Format each HD :

root@ubuntuserver:/home/edpteam# mkfs -t ext3 /dev/sda
mke2fs 1.40.8 (13-Mar-2008)
/dev/sda is entire device, not just one partition!
Proceed anyway? (y,n) y

Proceed anyway? (y,n) y
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)

4096000, 7962624, 11239424, 20480000, 23887872

Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 26 mounts or
180 days, whichever comes first. Â Use tune2fs -c or -i to override.
root@ubuntuserver:/home/edpteam#

Repeat this step for other HD .

4. Make mounting point for those HD.

Mounting point

root@ubuntuserver:/home/edpteam# mkdir /proxy
root@ubuntuserver:/home/edpteam# mkdir /probox
root@ubuntuserver:/home/edpteam# mkdir /netbox

Mounting to system.

root@ubuntuserver:/home/edpteam# mount -t ext3 /dev/sda /proxy
root@ubuntuserver:/home/edpteam# mount -t ext3 /dev/sdb /probox
root@ubuntuserver:/home/edpteam# mount -t ext3 /dev/sdc /netbox

Check if the HDs already mounted. (using command mount or df)

root@ubuntuserver:/home/edpteam# df -H
Filesystem Â Â Â Â Â Â Size Â Used Â Avail Use% Mounted on
/dev/sdd1 Â Â Â Â Â Â Â 67G Â 622M Â Â 63G Â 1% /
varrun Â Â Â Â Â Â Â Â 1.1G Â Â 46k Â 1.1G Â 1% /var/run
varlock Â Â Â Â Â Â Â Â 1.1G Â Â Â 0 Â 1.1G Â 0% /var/lock
udev Â Â Â Â Â Â Â Â Â 1.1G Â Â 95k Â 1.1G Â 1% /dev
devshm Â Â Â Â Â Â Â Â 1.1G Â Â Â 0 Â 1.1G Â 0% /dev/shm
/dev/sda Â Â Â Â Â Â Â 146G Â 197M Â 139G Â 1% /proxy
/dev/sdb Â Â Â Â Â Â Â 146G Â 197M Â 139G Â 1% /probox
/dev/sdc Â Â Â Â Â Â Â 146G Â 197M Â 139G Â 1% /netbox

5. Make permanent routing, just edit /etc/fstab

root@ubuntuserver:/home/edpteam# nano /etc/fstab

Save the file.

6. Done, next step is install Vmware server

LinuxSuse, count me in …

April 19, 2008 – 10:55 am

With recent version of linux suse 11 I got surprised to see big enhancement after my friend show me two books about OpenSuse.

1. openSUSE Linux Unleashed

Review from amazon :

[amazonify]067232945X:right[/amazonify]openSUSE Linux Unleashed presents comprehensive coverage of the community version of SUSE Linux, one of the most popular and most complete Linux distributions in the world.

This book provides detailed information on installing, using, and administering openSUSE. You’ll learn how to unleash the vast array of software products included in openSUSE so that you can use it as a desktop computer, as a professional workstation, or as a powerful server.

openSUSE Linux Unleashed includes a broad range of coverage: from using software you need everyday–such as email clients, web browsers, and productivity software including the OpenOffice.org productivity suite–to configuring and administering a wide range of network and server products, such as the Apache web server, and MySQL database.

Additionally, this book provides details on openSUSE’s acclaimed YaST administration tools, web programming, networking, and choosing from a wide selection of graphical interfaces and desktop environments, including both KDE and GNOME.

Plan your openSUSE installation based on your computing needs
Configure and use the X Window System–the Linux graphical interface–and the two primary desktop environments for Linux–KDE and GNOME
Run OpenOffice.org and other productivity tools
Create your own websites and weblogs
Manage the kernel and its modules
Set up networks
Run the Apache web server
Use the LAMP web programming suite: Linux, Apache, MySQL, and the scripting languages Perl, Python, and PHP
Play music, video, and games
Preserve an existing Windows installation for dual-boot launching

DVD-ROM includes:

The complete openSUSE 10.3 binary distribution–the equivalent of five CDs–packed with thousands of applications and utilities
The latest Apache web server
Samba for Windows-based file and printer sharing
The OpenOffice.org office productivity suite
Games for the desktop
Hundreds of additional programs, utilities, and development tools

2. SUSE Linux Toolbox: 1000+ Commands for openSUSE and SUSE Linux Enterprise

Try out over 1000 commands to find and get software, monitor system health and security, and access network resources. Apply skills you learn from this book to use and administer desktops and servers running openSUSE and SUSE Linux Enterprise or any other Linux distribution.

Reset Cacti Password, step by step

April 13, 2008 – 2:24 pm

My other staff ask me password for username admin. Yes, its administrator level in cacti.

After hardy trying to remember I gave up, I decide to reset it to other value but how?

I try to find out using database approach :

Here’s my steps :

1. Checking for cacti location and see db setting.

monitor# pwd

/usr/local/share/cacti/include

see setting dbnya.

monitor# cat db-settings.php

<?php
/* make sure these values refect your actual database/host/user/password */
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "cacti";
$database_port = "3306";
?>

2. Enter database with information taken from db-settings.php information.

monitor# mysql -ucacti -p

Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 8343
Server version: 5.0.45 FreeBSD port: mysql-server-5.0.45_1

Type ‘help;’ or ‘\h’ for help. Type ‘\c’ to clear the buffer.
