NX Remote Desktop Server

Nomachine NX

NoMachine NX is a fast terminal server and desktop virtualization system based on the X11 protocol. NX is an order of magnitude faster than VNC or X11 and can run on bandwidth as narrow as 10 kBit/sec. In addition, NX translates and embeds the MS Windows Terminal Server and VNC protocols into X/NX, enabling users to compress and accelerate remote Windows and VNC sessions. The NX project provides a suite of libraries and X11proxying agents implementing efficient compression and optimized transport of X11, SMB, IPP, HTTP, and arbitrary protocols like audio and video over the Internet.

Some Comment On FreshMeat:

NX is great - MUCH faster than VNC! But I do NOT recommend using FreeNX unless you want an exercise in frustration, or at least have access to the older client software (that, at least, seems to work, but not perfectly - in particular, I had font display issues when using FreeNX that I could not resolve, even after many hours of effort).

For those using Ubuntu or Kubuntu Linux, or who want to access their Linux box from a Windows machine using NX, you may find the instructions in this blog post useful:

NX with Win4Lin
I’ve Win4Lin (http://www.netraverse.com/) on one of my computers at office. I installed NX server on the same computer and I can now run Windows from home, through dial-up. It works better than the native RDP support I tested on XP.

Endian Firewall Router

What is Endian Firewall Community?

Endian Firewall Community is a "turn-key" linux security distribution that turns every system into a full featured security appliance. The software has been designed with "usability in mind" and is very easy to install, use and manage, without losing its flexibility.

The features include a stateful packet inspection firewall, application-level proxies for various protocols (HTTP, FTP, POP3, SMTP) with antivirus support, virus and spamfiltering for email traffic (POP and SMTP), content filtering of Web traffic and a "hassle free" VPN solution (based on OpenVPN). The main advantage of Endian Firewall is that it is a pure "Open Source" solution

Installing Oracle Application Server 10g

Learn the basics of installing Oracle Application Server 10g Release 3 on Red Hat Enterprise Linux or Novell SUSE Enterprise Linux, from the bare metal up (for evaluation purposes only).

Overview

The guide provides a walkthrough of installing Oracle Application Server 10g Release 3 on commodity hardware for the purpose of evaluation. If you are new to Linux and/or Oracle, this guide is for you. It starts with the basics and walks you through an installation of Oracle Application Server 10g Release 3 from the bare metal up.

This guide will take the approach of offering the easiest paths, with the fewest number of steps for accomplishing a task. This approach often means making configuration choices that would be inappropriate for anything other than an evaluation. For that reason, this guide is not appropriate for building production-quality environments, nor does it reflect best practices.

The Linux distributions certified for Oracle Application Server 10g Release 3 are:

• Red Hat Enterprise Linux 4 (RHEL4)
• Red Hat Enterprise Linux 3 (RHEL3)
• Novell SUSE Linux Enterprise Server 9 (SLES9)

We will cover both of the Linux 2.6 kernel-based distributions: RHEL4 and SLES9. RHEL3 is not covered here.

This guide is divided into three parts: Part I covers the installation of the Linux operating system, Part II covers configuring Linux for Oracle and Part III discusses the essentials of installing the Oracle Application Server.

---

Part I: Installing Linux

Hardware used for this walkthrough:

• 2.5GHz P4 CPU
• 1024MB of RAM
• Four SCSI disk drives (1 x 9GB + 3 x 36GB)
• One 100Base-T Ethernet adapter

Your hardware does not have to match this in order to use this guide. All that is necessary for a basic install is a single CPU, 512MB of RAM, and one disk drive (IDE, SCSI, or FireWire) with at least 700MB of free space.

Now, let's walk through the process of installing the Linux operating system on a server. The instructions assume a fresh install of Linux (as opposed to an upgrade), that the server will be dedicated to Oracle, and that no other operating systems or data are on the server.

---

RHEL4

Oracle Application Server 10g Release 3 is certified to run on Red Hat Enterprise Linux 4 (ES or AS) Update 1 or later. (Free evaluation copies of RHEL4 are available for download.) If you have update CDs, you can use the boot CD from the update instead of the boot CD from the base release to automatically apply all updates during the installation. All updates from Red Hat are supported by Oracle.

The easiest and fastest way to apply the updates for a fresh install of Linux is to perform the install by using the update CDs. If Linux is already installed or you don't have the updates on CDs, they can be applied through RHN. Because this guide is designed for a fresh Linux install, you'll use the update CDs.

1. Boot the server using the first CD.
• You may need to change your BIOS settings to allow booting from the CD.
2. The boot screen appears with the boot: prompt at the bottom of the screen.
• Select Enter to continue with a graphical install on the console. (For other installation methods and options, refer to the Red Hat Installation Guide.)
• The installer scans your hardware, briefly displays the Red Hat splash screen, and then begins a series of screen prompts.
3. Language Selection
• Accept the default.
4. Keyboard Configuration
• Accept the default.
5. Welcome Screen
• Click on Next.
6. Disk Partitioning Setup
• A thorough treatment of disk partitioning is beyond the scope of this guide, which assumes that you are familiar with disk partitioning methods.

(WARNING: Improperly partitioning a disk is one of the surest and fastest ways to wipe out everything on your hard disk. If you are unsure how to proceed, stop and get help, or you will risk losing data!)

This guide uses the following partitioning scheme, with ext3 for each filesystem:

The 9GB disk on the first controller (/dev/sda) will hold all Linux and Oracle software and contains the following partitions:
- 100MB /boot partition
-1,500MB swap partition—Set this to at least twice the amount of RAM in the system but to no more than 2GB. (Thirty-two-bit systems do not support swap files larger than 2GB.) If you need more than 2GB of swap space, create multiple swap partitions.
-7,150MB root partition—This partition will be used for everything, including /usr, /tmp, /var, /opt, /home, and more. This approach is purely to simplify installation for the purposes of this guide. A more robust partitioning scheme would separate these directories onto separate filesystems.

7. Boot Loader Configuration
• Accept the default.
8. Network Configuration
• It is usually best to configure application servers with a static IP address. To do so, click on Edit .
• A pop-up window appears. Uncheck the Configure using DHCP box, and enter the IP Address and Netmask for the server. Be sure that Activate on boot is checked, and click on OK .
• In the Hostname box, select manually and enter the hostname.
• In the Miscellaneous Settings box, enter the remaining network settings.
9. Firewall Configuration
• For the purposes of this walk-through, no firewall is configured. Select No firewall
• Select Disabled on the "Enable SELinux" drop down list.
• Click on Proceed when the "Warning - No Firewall" window appears.
10. Additional Language Support
• Accept the default.
11. Time Zone Selection
• Choose the time settings that are appropriate for your area. Setting the system clock to UTC is usually a good practice for servers. To do so, click on System clock uses UTC.
12. Set Root Password
• Enter a password for root, and enter it again to confirm.
13. Package Installation Defaults
• Select Customize software packages to be installed.
14. Package Group Selection
• Select only the package sets shown here and leave all others unselected.
• Desktop
• X Window System
• Gnome
• Applications
• Graphical Internet (optional)
• Servers
• Do not select anything in this group.
• Development
• Development Tools
• System
• Administration Tools
• System Tools
• Add the package 'sysstat' by clicking on the Details link and selecting "sysstat - The sar an iostat system monitoring commands." from the Optional Packages list.
• Miscellaneous
• Do not select anything in this group.
• Click on Next to proceed.
15. Installing Packages
• Software will be copied to the hard disk and installed. Change disks as prompted.
16. Congratulations
• Remove the installation media from the system, and click on Reboot .
17. The system automatically reboots and presents a new welcome screen.
• Click on Next.
18. License Agreement
• Read the license agreement. If you agree to the terms, select Yes, I agree to the License Agreement and click on Next.
19. Date and Time
• Set the Date and Time.
• If you want to use an NTP server (recommended), select Enable Network Time Protocol and enter the name of the NTP server.
20. Display
• Accept the defaults or change as required.
21. Red Hat Login
• Enter your Red Hat Network login and password or create a new one.
22. System User
• Create an account for yourself.
• Do not create an account for oracle at this time. Creating the oracle account is covered later in this section.
23. Additional CDs
• Click on Next.
24. Finish Setup
• Click on Next.
25. A graphical login screen appears.
26. Congratulations! Your RHEL4 software is now installed.

Verifying Your Installation

Part II: Configuring Linux for Oracle

Now that the Linux software is installed, you need to configure it for Oracle. This section walks through the steps required to configure Linux for Oracle Application Server 10g Release 3.

Verifying System Requirements

To verify that your system meets the minimum requirements for a Oracle Application Server 10g Release 3, log in as root and run the commands below.

To check the amount of RAM and swap space available, run this:

grep MemTotal /proc/meminfo
grep SwapTotal /proc/meminfo

Ex:
# grep MemTotal /proc/meminfo
MemTotal: 1034680 kB
# grep SwapTotal /proc/meminfo
SwapTotal: 1534196 kB

The minimum RAM required is 512MB, and the minimum required swap space is 1024MB. Swap space should be twice the amount of RAM for systems with 2GB of RAM or less and between one and two times the amount of RAM for systems with more than 2GB.

You also need 700MB of available disk space for the Oracle Application Server 10g Release 3 software. The /tmp directory needs at least 400MB of free space. To check the available disk space on your system, run the following command:

df -h

Ex:
# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 6.8G 1.3G 5.2G 20% /
/dev/sda1 99M 17M 77M 18% /boot

The example shows that the /tmp directory does not have its own filesystem. (It's part of the root filesystem for this guide.) With 5.2 GB available, the root filesystem has just enough space for the installation (2.5 + 1.2 + 0.4 = 4.1GB) with a little room left over.

Create the Oracle Groups and User Account

Next, create the Linux groups and user account that will be used to install and maintain the Oracle Application Server 10g Release 3 software. The user account will be called oracle, and the group will be oinstall. Execute the following commands as root:

/usr/sbin/groupadd oinstall
/usr/sbin/useradd -m -g oinstall oracle id oracle

Ex:
# /usr/sbin/groupadd oinstall
# /usr/sbin/useradd -m -g oinstall oracle
# id oracle
uid=501(oracle) gid=502(oinstall) groups=502(oinstall)

Set the password on the oracle account:

passwd oracle

Ex:
# passwd oracle
Changing password for user oracle.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.

Create Directories

Now create directories to store the Oracle Application Server 10g Release 3 software and its files.

The following assumes that the directories are being created in the root filesystem. This is done for the sake of simplicity and is not recommended as a general practice. These directories would normally be created as separate filesystems.

Issue the following commands as root:

mkdir -p /u01/app/oracle
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01/app/oracle

Ex:
# mkdir -p /u01/app/oracle
# chown -R oracle:oinstall /u01/app/oracle
# chmod -R 775 /u01/app/oracle

Setting Shell Limits for the oracle User

Oracle recommends setting limits on the number of processes and open files each Linux account may use. To make these changes, cut and paste the following commands as root:

cat >> /etc/security/limits.conf <> /etc/pam.d/login <

For RHEL4, use the following:

cat >> /etc/profile < if [ \$SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
umask 022
fi
EOF

cat >> /etc/csh.login < limit maxproc 16384
limit descriptors 65536
umask 022
endif
EOF

Part III: Installing Oracle Application Server 10g Release 3

Oracle Application Server 10g Release 3 for Linux can be downloaded from OTN. Oracle offers a development and testing license free of charge. However, no support is provided and the license does not permit production use. A full description of the license agreement is available on OTN.

The easiest way to make the Oracle Application Server 10g Release 3 distribution media available on your server is to download them directly to the server.

Use the graphical login to log in as oracle.

Create a directory to contain the Oracle Application Server 10g Release 3 distribution:

mkdir AS10gR3

After downloading Oracle Application Server 10g Release 3 from OTN, unzip and extract the file:

cd AS10gR3
cpio -idmv <>

Install the Application Server Software

Log in using the oracle account.

Change directory to the location where you extracted the Oracle Application Server 10g Release 3 software.

Ex:
$ cd $HOME/AS10gR3

Start the Oracle Universal Installer.

$ ./runInstaller

1. Oracle Application Server 10g 10.1.3.0.0 Installation
• Installation Directory: /u01/app/oracle/product/10.1.3/OracleAS_1
• Select Basic Installation
• Installation Type: Integrated Webserver, J2EE Server, Process Management
• Instance Name: appserver
• Administration Name: oc4jadmin (cannot be changed)
• Administration Password: Enter a password and confirm
• Click on Install
2. Specify Inventory Directory and Credentials
• Inventory Directory: /u01/app/oracle/oraInventory
• Operating System group name: oinstall
• Click on Next
• Run the indicated script as root and click on Continue
3. Product-specific Prerequisite Checks
• If you've been following the steps in this guide, all the checks should pass without difficulty. If one or more checks fail, correct the problem before proceeding.
• Click on Next
• Dismiss the Warning window that may appear regarding installed physical memory by clicking on OK.
4. Install
• Watch the installation process
5. Configuration Assistants
• The configuration assistants should succeed without any action on your part.
6. Setup Privileges
• At the end of the installation, a pop up window will appear indicating that a script needs to be run as root. Login as root and run the indicated script.
• Click on OK when finished.
7. End of Installation
• Make note of the URLs presented in the summary, and click on Exit when ready.
8. Congratulations! Your new Oracle Application Server 10g Release 3 is up and ready for use.

FreeBSD..........................Installation very easy.


After 2 month worked at Balicamp with full loading jobs, help user to using Open Source Software somewhere i'm just know basic it, before helping them i'm must explore and googling about thier problem to solve that problem.

last week my user send job request to me to instllation FreeBSD, ups.... i'm never doing installation before n so i don't know basic unix operating system, to make all run properly i'm trying do installation on other pc to test n trial it... after once installation is fail, freebsd no running, i'm tyr new installation again...ahhhhh its Running smooth...

clue to running... we must peruse step-step installation on display

Install Ubuntu 7.10 "Gutsy Ribbon" from USB flash

Install Ubuntu 7.10 from USB Flash Drive

A. Checking your USB stick

Booting from USB memory sticks is neat, but there is no guarantee that it works with your particular combination of computer and USB stick. Even if you are able to boot from your flash drive on one computer, this does not mean that it is going to work with the next one. You can try experimenting with different settings in your PC's BIOS to make it work.

B. Making your flash drive bootable with SYSLINUX

SYSLINUX is a boot loader that operates off an MS-DOS/Windows FAT filesystem. Most USB flash drives come with a FAT filesystem. Here's how you can add a SYSLINUX bootblock to your USB stick, link download TAR GZ FIle for Linux, ZIP file for windows

1. installed syslinux" and "mtools" on your PC, on Ubuntu :$ sudo apt-get install syslinux mtools
2. Attach your USB flash drive to your computer and mount it.
3. Make the flash drive bootable, for Windows on dir win32 use command : syslinux -s F: (assuming F is your USB) drive for linux use: syslinux -s /dev/sdb1. (assuming that /dev/sdb1 is your usb flash drived mounted)
4. should see a new file called ldlinux.sys in the root directory of your flash drive.

C. Copying the Ubuntu CD to your flash drive

Copy the contents of the Ubuntu installation CD to your flash drive dont copy an ISO image of the installation CD file to your flash drive.

From a Windows command prompt use : xcopy /e /h /k d:\*.* f: (assuming that D: is your CD-ROM drive and F: is the USB stick:).

D. Rename Directory and files

Rename the isolinux directory to syslinux and the two files isolinux.bin and isolinux.cfg to syslinux.bin and syslinux.cfg on syslinux directory.

E. Boot Computer from your USB flash drive.

New Office New Jobs

Dah sebulan pindah ke kantor baru, semuanya serba baru
mulai dari teman kerja sampai program dan Operating System yang di gunakan...
lokasi kantor yang sekarang ini juga baru jauh dari pusat kota tapi sangat nyaman..
pergi kerja tidak jauh, gak macet dan pulang juga gitu....

kantor yang sekarang OS untuk user pakai open source atau lebih di kenal dengan linux,
pilihannya mengunakan linux UBUNTU Feisty 7.04
alasan nya selain mudah mudah porses instalasinya dan dan juga udah lengkap aplikasinya
untungnya user dikantor yang baru ini semuangya orang IT jadi tidak perlu mengasih tahu terlalu ditel.
tapi saking sibuknya sebulan ini jarang ol jadinya...........heheee

dari bebera bulan ini banyak banget ilmu yang di dapat
mulai mail server opensource, DNS Server dan Firewall router.
pada dasar di akntor bar cukub menyenangkan dan banyak tantangannya
tapiyang kurang di sini rasa kekeluargaan dan karir....
kalau di lihat dr struktur perusahaan kariir mentok disini..sebagai system support.
tp yang penting sekarang dijalani aja duluu..

Squid for Windows

Squid merupakan salah satu software untuk caching web.
dan biasa juga disebut proxy ..
squid berkerja dengan cara menyimpan content alamat web
yang pernah di kunjungi oleh satu user
pada halaman cachingnya....
jika ada user lain yang mau browsing web yang sama
maka tidak lagi langsung mengaksess ke halam webnya,
tp cukup sampai di proxy ajaa.

Pada awalnya squid hanya bisa di gunakan di Linux....
tp saat in dah ada juga untuk windows,,,,,

yang mo download squid untuk windows :

WaRnet dan Game OnLine Center

Seminggu yang lalu..teman gw cerita.. kalau Bossnya mo jual warnetnya..
teman gw itu inginnya dia yang ambil or beli dari Bossnya sekarang..tapi itu dananya lagi di usahaain ma dia...n skrg di di lagi Pulakn untk cari modalnya...hiks..hiks.....

Pada dasarnya gw juga beminat untuk investasi di warnet...
menurut gw... internet saat ini dah menjadi kebutuhan bagian besar orang2..betul ga sih??
kalau gw pribadi Internet saat banyak sekali membantu gw
mulai dari cari kerjaan..
membantu memecahkan masalah dalam perkerjaan (kebetulan gw kerja di bidang IT)
dan bisa juga menjadi guru bagi gw,
bagi orang lain...kiraa2...bgitu juga ga ya...

Saat iNi menurut gw saat usaha warnet masih menjanjikan..
tapi rata2 warnet yang hanya bisa chat browsing dan sejenisnya...dah mulai ga ramee
biasanya yang main pemula atau anak2 sekolah yang update FS aja...
tapi anak-anak zaman sekarang lebih kebanyakan suka....ngegame..
makanya rencannya nih gw ma teman mo ambil warent ini...
na d juga mo tambah investasi mo jadiin game station juga

Dari pengalaman gw biasanya warnet yang di lengkapi ma game station selalu penuh..
dari prospek yang ada di sini kelihatnya juga begitu
warnet yang ada game stationya bisa dihitung..
jadi saingan juga belum banyak...

Masalahnya kompi warnet yang existing sekarang itu
rata2 pentium 3 memori 256 nad vag 32MB
dan tempatnya kurang lega...
mo jadiin game station harus tambah PC dan tempat...juga.
untuk kebutuhan games station dari pengalamanya speck pc juga gak harus tinggi..banget
dengan pentium 3 juga ok di topang memori minimal 512Mb n VGA 128 Mb
atau mo bagusan sekalian juag bisa pakai pentium 4 dengan memory 512 dan VGA 128
harag PC baru untuk Pentium 4 dengan harga 3jtan..

Jadi rencanya usaha warnet yang ada sekarang ini akan di jadin Game Station
yang bisa game OL juga seperti Pangya, Xian, PlaOn, Seal Online dan Ragnarog.
dan gam Offline lainya.....

ada yang mo gabung Investasi ?
