I have already contacted avast tech. support, I receive this messages:

"Dear customer,
Hello,

Thank you for contacting our support center with your concerns.

There are three parts of the program, where exclusion can be dealt.
It depends on which one you need to use.

First is File system shield that takes care of real time protection. Click on REAL-TIME SHIELDS - File system shield and press Expert Settings button. Choose Exclusions and modify existing list or add any other files to be excluded according to your needs.

If you want to exclude files from on demand scan, click on Settings button in the main Interface window and choose Exclusion and type any path to be excluded from scanning.

Last exclusion concerns web sites. In "REAL-TIME SHIELDS", click on the Web shield icon and then on Settings button on the right side of the screen.
Then choose Exclusions and tick URL´s to exclude. Enter any desired url/s and confirm it clicking on "Add" button.

I decide to find the solution by my self, I start to tracking each process, debugging process, investigating registry changes, exploring DLL etc. When Real-time shields activated there are some process that "protecting system from changes". Binggo!! that is the key. After do many trial at last I found the solution to fix error 0xc0000005.

Here are permanent solution to Fix Avast Error 0xc0000005 :
1. Go to Real-time shields > Behavior shield

2. Choose Expert Settings

3. Uncheck "Monitor the system for unauthorized modifications"

4. Finish

Thanks for reading my simple articles about how to fix Avast Error 0xc0000005.

Avast do you need high qualified tech. support? call me now, I'm free :D, just kidding, my father's in not good health condition, impossible for me to work overseas.

Vote For Muslim in German

noreply@blogger.com (rachmat) — Tue, 22 Feb 2011 06:17:00 +0000

A freedom to choose a religion is human right, but now in Germany, the religion of Islam is questionable whether it is proper to be part of germany?

Well as the brother of fellow Muslims rightly we support, by participating in the voting conducted by the site umfrage.tagesschau.de

that site said "his speech on the Day of German Unity President Wulff stressed that Christianity and Judaism were part of Germany. That is our Christian-Jewish history. And he made it clear: "But Islam is now also to Germany." Do you agree?

Editor's note: This poll is closed since October - a vote is not possible since then. Nevertheless, this survey is currently being "applied" in multiple networks - why, we do not know."

How to participate?
just go to http://www.tagesschau.de/inland/wulffrede112.html , Choose "Ja" and send with click "Zur Auswertung"

Be quickly, vote only available until october 2011, tell your friends as much as you can, thanks for reading my article about Vote For Muslim in German.

Hardening Linux with Iptables and disabling uneeded services

noreply@blogger.com (rachmat) — Tue, 15 Feb 2011 18:15:00 +0000

Preface
Many methode to secure your linux box, such as: audit your SELinux, scanning for rootkits, optimizing kernel, adding iptables, disabling uneeded services, user and group policies etc.
This time I will share You about Hardening Linux with Iptables and disabling uneeded services .
FTP Services by default on Linux Fedora are disable, so I will pass it.
The usualy vulnerable services that discovered by IT Auditor such as:
-Send Mail,
An Attacker can send fake email to sender
-Bluetooth
Anonymous User can send harm content to your Linux Box
-NFS (Network File Sharing)
NFS can be a hole by attacker to gain access to your Linux Box
-RPC (Remote Procedure Calls)
If this services activated, someone can monitoring remotely to your Linux Desktop
-HTTPD (Http Server)
The commonly attacked service is Http Web Server, better to disable this service If You not using this services
-SSHD (SSH Server)
SSHD service is used to connect securely on remote devices.
If Your Linux using SSH-1 Better to disable this service If You don't want your Linux Box got "man in the middle attack".
-Open VPN
Some Linux Box are vulnerable to this services, USN-612-3 "A weakness has been discovered in the random number generator used by OpenSSL on Debian and Ubuntu systems. As a result of this weakness, certain encryption keys are much more common than they should be, such that an attacker could guess the key through a brute-force attack given minimal knowledge of the system."
Securityfocus.org said that "An attacker can use the standard OpenVPN server application to exploit this issue."

The commonly open port used by attacker, such as:
-2049 , Network File System
-6000:6009 , X11
-7100, x font service, Used by rootkit and trojan backdoors
-631, CUPS (Common Unix Printing System)
-515, Printer Daemon
-445, SMB file sharing
-443, Https
-161, SNMP , this is optional, you can enable it if your snmp community string are used to monitor any trap messages.
-137 – 139, NetBIOS over TCP/IP
-135, RPC
-111, SunRPC
-110, Pop3
-80, HTTP
-20-21, FTP
-22, SSH
-23, TELNET
-25, SMTP

How to Hardening Linux with Iptables and disabling uneeded services ?
Here are the steps:
1. Copy this scripts using your text editor, and save it @ /usr/local/src, with name myrules.sh,

#!/bin/bash
service sendmail stop
service bluetooth stop
service cups stop
service nfs stop
service nfslock stop
service openvpn stop
service rpcbind stop
service rpcgssd stop
service rpcidmapd stop
service rpcsvcgssd stop
service rsyslog stop
service httpd stop
service sshd stop
chkconfig sendmail off
chkconfig bluetooth off
chkconfig cups off
chkconfig nfs off
chkconfig nfslock off
chkconfig openvpn off
chkconfig rpcbind off
chkconfig rpcgssd off
chkconfig rpcidmapd off
chkconfig rpcsvcgssd off
chkconfig rsyslog off
chkconfig httpd off
chkconfig sshd off
iptables -I INPUT -p udp --dport 2049 -j DROP
iptables -I INPUT -p tcp --dport 6000:6009 -j DROP
iptables -I INPUT -p tcp --dport 7100 -j DROP
iptables -I INPUT -p tcp --dport 631 -j DROP
iptables -I INPUT -p udp --dport 631 -j DROP
iptables -I INPUT -p tcp --dport 515 -j DROP
iptables -I INPUT -p tcp --dport 445 -j DROP
iptables -I INPUT -p tcp --dport 161 -j DROP
iptables -I INPUT -p udp --dport 161 -j DROP
iptables -I INPUT -p tcp --dport 137:139 -j DROP
iptables -I INPUT -p udp --dport 137:139 -j DROP
iptables -I INPUT -p tcp --dport 135 -j DROP
iptables -I INPUT -p udp --dport 135 -j DROP
iptables -I INPUT -p tcp --dport 111 -j DROP
iptables -I INPUT -p udp --dport 111 -j DROP
iptables -I INPUT -p tcp --dport 110 -j DROP
iptables -I INPUT -p tcp --dport 20 -j DROP
iptables -I INPUT -p tcp --dport 21 -j DROP
iptables -I INPUT -p tcp --dport 22 -j DROP
iptables -I INPUT -p udp --dport 22 -j DROP
iptables -I INPUT -p tcp --dport 23 -j DROP
iptables -I INPUT -p tcp --dport 25 -j DROP
iptables -I INPUT -p all -s localhost -i eth0 -j DROP

2. Modify /etc/rc.local
You will see something like this:

type /usr/local/src/myrules.sh before touch /var/lock/subsys/local .

3. Finish, now reboot your Linux box ^_^

Notes:
I used -I option on Iptables to executed at first sequence before default iptables script.
chkconfig used to disable services, it's not enough if only stopping the uneeded services.
Always thinking out of the box, about myrules.sh is based on my system requirement rules, you can adjust or modifying this script depend on your requirement.
I'm not disabling http and https port because I connect to internet without using any proxy.

SSH Server on Redhat

noreply@blogger.com (rachmat) — Thu, 10 Feb 2011 09:45:00 +0000

Pada postingan kali ini rachmat mau share tentang cara setting SSH Server on Redhat,
Ga banyak basa basi neh, langsung aja ya, tarik mang! ......

OS: Redhat
user: rachmat
passwd: eccouncilvscheckpoint
domain: therachmat.com <aktifkan dns-server arahkan therachmat.com ke server local>

1. Pastikan agar kita bisa login via ssh, ubah shell login
#cat /etc/passwd | grep ssh
secara default hasilnya "sshd:x:74:74:Privilege-separated SSH:/var/empty/sshd:/sbin/nologin
maka ganti dengan gedit /etc/passwd "sshd:x:74:74:Privilege-separated SSH:/var/empty/sshd:/sbin/sshd" lalu save

2. aktifkan service sshd
#service sshd start
Generating SSH1 RSA host key: [ OK ]
Generating SSH2 RSA host key: [ OK ]
Generating SSH2 DSA host key: [ OK ]
Starting sshd: [ OK ]

3. Buat username & password
misalnya servernya therachmat.com, usernamenya rachmat passwordnya eccouncilvscheckpoint

4. Coba Login ke SSH Server
[root@rachmat rachmat]# ssh therachmat.com -l rachmat
rachmat@therachmat's password: <eccouncilvscheckpoint>
Last login: Fri Feb 12 02:45:11 2010 from therachmat.punya_domain (aamiiin)

5. Selesai

tambahan untuk security, agar tidak bisa login sebagai root, maka
modify PermitRootLogin yes jadi no /etc/ssh/sshd_config

# Authentication:

#LoginGraceTime 2m
#PermitRootLogin yes
#StrictModes yes
#MaxAuthTries 6
#MaxSessions 10


# Authentication:

#LoginGraceTime 2m
PermitRootLogin no
#StrictModes yes
#MaxAuthTries 6
#MaxSessions 10

Lebih jauh tentang SSH:
Selain sshd_config dan ssh_config, file2x berikut ini bisa juga dikonfigurasi:
-ssh_host_dsa_key
-ssh_host_key.pub
-ssh_host_dsa_key.pub
-ssh_host_rsa_key
-ssh_host_key
-ssh_host_rsa_key.pub

Thanks yah udah baca artikel sederhana rachmat tentang SSH Server on Redhat

Automat Scan twitter followers

noreply@blogger.com (rachmat) — Tue, 08 Feb 2011 07:15:00 +0000

This time I will share U about how to automat scan twitter follower.
Preface,
Follow as much as you can are good to get new follower.
But since You have too much people to follow, U will get this message by twitter " Oops, You have reached limits bla2..."

Then I go to support.twitter.com to find why this is happen?
I got this messages:
"We do not limit the number of people who can follow you, but we have put limits on how many other accounts you can follow.
Every account can follow 2,000 users total. Once you’ve followed 2,000 users, there are limits to the number of additional users you can follow. This number is different for each account and is based on your ratio of followers to following; this ratio is not published. Follow limits cannot be lifted by Twitter and everyone is subject to follow limits, even high profile and API accounts.
In addition to this account-based limit, every Twitter account is technically unable to follow more than 1,000 users per day. Please note that this is just a technical limit to prevent egregious abuse from spam accounts. Accounts are also prohibited from aggressively following other users. Our Follow Limits and Best Practices Page has more information on Twitter’s following rules."

But why others can follow over than 2000?
Focus at this statement:
"based on your ratio of followers to following; this ratio is not published. Follow limits cannot be lifted by Twitter and everyone is subject to follow limits"

This mean if You want follow people more than 2000, you must also have ratio follower close to 2000.
Good ratio is followers > following, followers = following.

How I can know which people I follow are not following me back again?
Go To who.unfollowed.me/lite , then sign in with your twitter account, now you will able to scan twitter followers.
There are 3 options to scan twitter followers:
-check unfollowers
-who's not following me back
-unfollower history

When You Choose who's not following me back, You will see something like this:

What I do next? All you need to do is unfollow people that listed in people that aren't following me back.
Congrats.... Now You can follow back new followers again.... ^_^

Thanks for reading, my special thanks to: who.unfollowed.me

Trouble Shoot C++ From Zero Part 1

noreply@blogger.com (rachmat) — Tue, 01 Feb 2011 02:56:00 +0000

After I wrote about Learning C++ from Zero Part 1 Now I will share you about how to trouble shoot C++,

Algorithm:
-Initialization
HotCoffeeMilk <- 0
Cup <- 1
Spoon <- 1
MilkPowder <- 1
Sugar <- 1
HotWater <- 1
-Process
Cup <- Cup + MilkPowder
Cup <- Cup + Sugar
Cup <- Cup + HotWater
Cup <- Cup + HotWater
While Sugar = 1, Coffee = 1, HotWater = 1 and MilkPowder = 1 do
Cup <- Cup + Spoon
if Cup = 30 then
Sugar <- 0
Coffee <- 0
MilkPowder <- 0
{end if}
{end while}
-Finalization
HotCoffeeMilk <- 1
{end procedure}

The Codes,

The Problems,

Trouble shoots steps:
1. See error messages
2. Focus to a specific error line, try to understand error messages
3. Do analytics thinking, what fix should be?
4. Go to another line and fix it
5. After all lines checked and fixed, run program again with "gcc Trouble_Coffee_p1.cpp"
- If still see error messages, see detail whole codes from start to end, do integral thinking (compare structures with algorithm),
Then go to no 2 - 4 again
- If you still don't know how fix should be? , search online about anything related to error messages.
- If you're stuck don't know what to do, ask c++ forums
6. Finish, nothing error messages appear

See Problems (error messages) then go to spesific line:
-33:9 & 33:2: warning: missing terminating " character
this is line 33 -> printf("HotCoffeeMilk already to drink... yummy!! \");
33:2 -> no problems @ printf("
33:9 -> missing n after \
it should be, printf("HotCoffeeMilk already to drink... yummy!! \n");

Go to another line and fix it:
-7:2: error: expected ',' or ';' before 'int',
this is line 7 -> int Spoon = 1; and this is before int (line 6) -> int Cup = 1
missing ; after 1
it should be, int Cup = 1;

-12:8, 15:9, 17:8, 19:8, 21:8 expected constructor, destructor, or type conversion before '(' token
12:8, printf("Cup, Spoon, Coffee, MilkPowder, already exist \n");
12:8, nothing wrong here
15:9, prinntf("Cup added with MilkPowder \n");
15:9, wrong syntax @ prinntf, it should be printf
17:8, printf("Cup added with Coffee \n");
17:8, nothing wrong here
19:8, printf("Cup added with Sugar \n");
19:8, nothing wrong here
21:8, printf("Cup added with HotWater \n");
21:8, nothing wrong here

-14:2, 16:2, 18:2, 20:2 error: 'Cup' does not name a type
14:2, Cup = Cup + MilkPowder;
14:2, nothing wrong here
16:2, Cup = Cup + Coffee;
16:2, nothing wrong here
20:2, Cup =Cup + HotWater;
20:2, missing <space> after =, it should be Cup = Cup + HotWater;

-22:2: error: expected unqualified-id before 'while'
22:2, while ((Sugar == 1) && (Coffee == 1 && (MilkPowder == 1) && (HotWater == 1)) {
22:2, missing ) at (Coffee == 1, it should be (Coffee == 1)
Search before 'while' ,
-in at in main () [line 3] should be int

After all lines checked and fixed, run program again with "gcc Trouble_Coffee_p1.cpp"

wow... as You can see, error messages still appear, like I said before, see whole codes from start to end,
There is nothing wrong if we compare the codes with algorithm,
last error said, expected unqualified-id before 'while' that is the key.
it must be something wrong before while,
hey... see structures (tree), the integer main should be as 1st tree, and others as sub tree.
in notepad ++, before int main should be a tree [-], it must me something wrong before int main [3:1]
focused at /* This is Coffee MilkPowder Program *, there was a comment that missing / to terminate comment.
it should be /* This is Coffee MilkPowder Program */
congrats, now structures are correct.

run program again with "gcc Trouble_Coffee_p1.cpp"
we still see 2 error messages:

This code is mean expected '}' for terminate int main, but '}' already added for end procedure [35:1].
see the lines before, focused at '}' only.
binggo... there is expected '}' to terminate if [29:1]
[29:1], } /* end if */

run program again with "gcc Trouble_Coffee_p1.cpp"

Finish... nothing error messages appear

The right codes:

Conclusion:
-read carefully error messages, sometimes there is no explain about specific line that cause an error.
e.g.: see [29:1] , no error messages for this line
-always think out of the box, if you think already fix all of errors but in fact error still exist
-Programmer jobs is not only how to make an efficient codes, right? but how to trouble shoot codes issues...

Learning C++ from Zero Part 1

noreply@blogger.com (rachmat) — Thu, 27 Jan 2011 15:41:00 +0000

After I wrotes about Secret codes on Samsung Omnia Pro and how Install Ebuddy on Samsung Omnia Pro,
Now I will share you about Learning C++ from Zero.

Preface
What is C++?
C++ is a middle level language program, the development of C.
The type of C++ coding is case sensitive, wrong only one character in coding can make program not run well.

What is Algorithm?
Algorithm is solution methode that programmer use to make a program.
Different algorithm methode will affect the rate of efficiency in making the source code of program.

We will make simple program of Hot Coffee Milk.
#1 Alogrithm:
-Initialization
HotCoffeeMilk < - 0
Cup < - 1
Spoon < - 1
MilkPowder < - 1
Sugar < - 1
HotWater < - 1
-Process
Cup < - Cup + MilkPowder
Cup < - Cup + Sugar
Cup < - Cup + HotWater
Cup < - Cup + HotWater
While Sugar = 1, Coffee = 1, HotWater = 1 and MilkPowder = 1 do
Cup < - Cup + Spoon
if Cup = 30 then
Sugar < - 0
Coffee < - 0
MilkPowder < - 0
{end if}
{end while}
-Finalization
HotCoffeeMilk < - 1
{end procedure}

Explanation,
Initialization is declaration of variable. HotCoffeeMilk set to zero is mean Hot Coffee Milk not ready yet. Cup, Sugar, MilkPowder and HotWater set to 1 is mean the resource already exist. Process is mean the making of Hot Coffee Milk. While sugar and Milk Powder is exist then do stir the ingredients with a spoon. if the ingredients has stirred as much as 30 times then coffee, milk and sugar is considered to have dissolved.
The Codes:

Program Preview:

#2 Alogrithm:
-Initialization
HotCoffeeMilk <- 0
Cup <- 1
Nescafe_3in1 <- 1
HotWater <- 1
-Process
Cup <- Cup + Nescafe_3in1
Cup <- Cup + HotWater
While HotWater = 1 and Nescafe_3in1 = 1 do
Cup <- Cup + Spoon
if Cup = 30 then
Nescafe_3in1 <- 0
{end if}
{end while}
-Finalization
HotCoffeeMilk <- 1
{end procedure}

Explanation:
With Nescafe 3 in 1 More Simple Steps to make a Hot Coffee Milk, right ?
Ingredients of Nescafe 3 in 1 are Coffee + Sugar + MilkPowder
The Codes:

Program Preview:

Conlcusion:
Programming is not only how to code?, but also how to make an efficient steps and more simplify codes.

Thank You for reading my article about Learning C++ from Zero Part 1, If You like with my article please give me a backlink to this blog, I hope after you reading this article gives You another perspective about programming.

RAMNIT Worm Removal Guide

noreply@blogger.com (rachmat) — Wed, 26 Jan 2011 06:45:00 +0000

Yesterday ago my father PC's got infected by worm VBS dropper.
This worm known as RAMNIT by Clamwin antivirus signatures.
The badnews are He plug-in his usb flash disk to my PC's and executed some files that maybe contains virus and worms.
I think realtime protection of clamwin is fair, not much help against this worms and my PC's also got infected by this worms.
Searching in internet no complete guide removal for healing this Ramnit worm.
After learning the characters of this worm, finally I wrote this article.
Here are step by step Ramnit removal guide:

1. Run Process explorer from sysinternal (now microsoft), click suspend all svchost.exe (under explorer.exe process, not under services.exe) then terminate process tree
2. Disable system restore during this removal steps.
3. Erase recycler, recycled and "system volume information" folders, To doing this follow this steps:
(for example my admin username is rachmat, root directory is in C:, and my data directory is in D:)
-run cmd.exe,
c:\>rd /s /q "c:\recylcer" [enter]
c:\>cacls "c:\system volume information" /t /e /c /g rachmat:F [enter]
c:\>rd /s /q "c:\system volume information" [enter]
d:\>rd /s /q "recycled" [enter]

4. Make RamNit_removal.bat and RAMNit_removal.reg and place it at the same path / folder. To make this files here the steps:
-run notepad, copy this scripts and save as RamNit_removal.bat
@echo off
REM "This is for erase Main worm files"
del /f /s /q /a "%ProgramFiles%\Microsoft\WaterMark.exe">Delete_Log.txt
del /f /s /q /a "%ProgramFiles%\Microsoft\DesktopLayer.exe">>Delete_Log.txt
del /f /s /q /a "%systemroot%\System32\dmlconf.dat">>Delete_Log.txt

Install Ebuddy on Samsung Omnia Pro

noreply@blogger.com (rachmat) — Mon, 17 Jan 2011 09:50:00 +0000

This time I will share about how to install ebuddy on omnia pro aka Samsung GT-B7320.
when I go to ebuddy sites I can't find my omnia pro in samsung model selection.

Big question for me, why???

Finally I find a clue...

Why People said that Samsung Omnia Pro is Samsung Jacky?
Yes, offcourse the model is very close to Samsung Jack.
Then I go to ebuddy sites again, but I only find samsung black jack II.
Lets think out of the box, I think the reason about why ebuddy not listed omnia pro is because the previous version was already release on ebbudy sites.

I think now you know the answers, I open my opera in my samsung omnia pro, go to ebuddy sites and choose samsung black jack II.

Brand: Samsung
Model: sgh-i617 black jack ii

After installation process go to application > java > ebuddy.

Now, Have fun with your ebbudy.

Thanks for reading my simple article about install ebuddy on samsung omnia pro.
This is my first come back after for long time hiatus.

Pamit Hiatus

noreply@blogger.com (rachmat) — Fri, 29 Jan 2010 14:16:00 +0000

Bro n Sis, tadi marketing Fristmedia menelpon saya, mba Sisca namanya..... katanya FastNet 384 kbps masa berlakunya sudah berakhir

Jadi bandwith minimalnya 512 kbps, biaya bulanany 180 ribu sampe 200 ribuan.

Karena kenaikan biaya itulah saya memutuskan untuk berhenti menggunakan FastNet, insya Alloh sebelum tanggal 15 feb saya konfirm

Oleh karena itu saya pamit hiatus nih, thanks ya temend2 semua, telah mewarnai therachmat , thanks juga ya buat mba Sisca dan kru Firstmedia.

Sementara saya mencari paket internet yg "harga rakyat", maka blog therachmat akan hiatus, entah untuk waktu berapa lama, padahal masih banyak yg ingin saya share di therachmat.

ini kira2 rencana next posting saya di therachmat -> tutorial C++ , vibi 6.0, php n mySQL, Linux Backtrack, Metasploit, Mikrotik, BGP routing di GNSrouter, DNS server, mail Server, Active directory, Network Monitor dsb.

Oya, kalo mas romi SW diblognya pernah bilang "VLSM siapa takut", sebenarnya saya juga udah punya artikel tentang VLSM, hanya saja belum sempat saya posting, judulnya "VLSM, mau berapa Network?" , VLSMnya ip kelas A serta kelas B, tingkat subnetingnya diatas 16 K (mulai 10 ribu host hingga diatas 10ribu host).

Sedangkan untuk blog ziddu-me, ini kira2 next posting saya, module CEH, CHFI, Linux BackTrack 4 new release, koleksi ebook Onno W Purbo ... dsb
Udah dulu ya ketak ketiknya, saya Oph dulu ya, take care all, I will miss U all forever my friends ^_^

Saya pamit Hiatus, hik hik hik......

Pesen untuk semua blogger:
Tetep semangad ya!!! Teruslah bermimpi dan meraih mimpimu!!! Yakinlah Alloh SWT punya jalan special yang tak terduga2 untuk membawamu menuju jalan sukses.

NLite OS

noreply@blogger.com (rachmat) — Tue, 26 Jan 2010 08:13:00 +0000

Setelah rachmat share tentang DHCP Server sekarang rachmat mo share tentang Nlite OS.

Intermezzo
Apa itu Nlite OS?
Nlite OS adalah tools untuk custom install windows (NT/2000,Xp,Vista), kita bisa menambahkan service pack, driver, components, option, serta tweaks.
Bagaimana cara install Nlite OS?
install .net framework , setelah itu install Nlite OS :)

Pada tutorial kali ini kita akan menambahkan driver SATA ke dalam installer Xp untuk notebook Acer.
Yuk temend2x.... kita mulai tutorialnya,

1. Jalankan Nlite OS, pilih Next

2. Browse CD installer Xp, pilih Next

3. Buat folder untuk tempat simpan Custom Xp, lalu pilih Next

4. Pilih Drivers dan Bootable ISO, Next

5. Insert Driver SATA

6. Pastikan informasi driver sudah masuk, lalu Next

7. Make ISO, pilih lokasi save-nya , Next

8. Custom Xp dengan NLite OS, selesai

9. Burning deh iso image Custom Xp

DHCP Server

noreply@blogger.com (rachmat) — Sun, 24 Jan 2010 02:23:00 +0000

Preface
Sebelum kita mulai tutorial, kita bahas dulu dikit tentang macam2 server.
Server itu bisa sebagai Application Server, DHCP Server, Mail Server, Web Server, Advanced Server dsb (sesuai kebutuhan ^_^).

Nah pada postingan kali ini rachmat maw share tentang cara konfigurasi DHCP Server. Nantinya client mendapat ip address dirinya serta ip address router, sedangkan untuk ip dns servernya si client nembak ke open dnsnya google

Oke, tancap mang.... hehe
Berikut adalah step by step tutorial DHCP Server

1. buat Topologi, misalnya gateway ke 1 router, jumlah client 5 dan 1 server.

Network Address 192.168.0.0 /28
Ip address Server 192.168.0.1 (Static)
Ip address Router 192.168.0.11 (Static)

Ip address Client 192.168.0.2 - 192.168.0.14
(DHCP)

2. buka start menu > Programs > Administrative Tools > DHCP

3. Pilih New Scope, isi nama scope dan description

4. Isi Ip address u/ client range dan length (prefix)

5. Add exclusion ( ip staticnya server )

6. Tentukan lease Duration, misalnya 23 jam

7. Pilih Yes, I want to configure these option now, lalu next

8. Isi ip address untuk gateway/router

9. Active Scope Now, Next, nanti akan tampil scopenya seperti ini,

10. Pastikan Client dapat ip address,

(ipconfig/release, ipconfig/renew,ping sukses)

Registry Repair

noreply@blogger.com (rachmat) — Tue, 12 Jan 2010 16:07:00 +0000

Pada postingan kali ini saya akan sharing tentang cara repair registry yang sebagian settingnya rusak karena ulah virus.

Sebelumnya saya ingin memberi tahu tentang cara2 mengakses registry, antara lain:

-Regedit (registry editor)

caranya run regedit, nanti sobat bisa cari string/key, modify value, buat key & subkey dsb.

-Command Prompt

caranya run cmd.exe,

REG ADD KeyName [/v ValueName | /ve] [/t Type] [/s Separator] [/d Data] [/f]

misal: Membuka Registry yang dikunci,

reg add "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System" /v DisableRegistryTools /t REG_DWORD /d 0 /f

-INF (file installation info)

caranya klik kanan lalu install

misal: Mengaktifkan WSH serta Membuka Registry yang dikunci
[Version]

Signature="$Chicago$"

Provider=Therachmat Community
[DefaultInstall]
AddReg=UnhookRegKey
DelReg=del
[UnhookRegKey]
HKLM, SOFTWARE\Microsoft\Windows Script Host\Settings\Enabled"type,1,"checkbox"

[del]

HKCU, Software\Microsoft\Windows\CurrentVersion\Policies\System, DisableRegistryTools

-WSH (Windows Scripting House e.g: vbs , js)

caranya: buka notepad lalu simpan scriptnya dengan extensi vbs

misal: Membersihkan Start Up di msconfig

[VBScript]

'my name is Repair by rxnux3r

msgbox "Repair Registry"

Dim rxnux3r: Set rxnux3r = CreateObject("W" & "S" & "c" & "r" & "i" & "p" & "t" & "." & "Shell")

on error resume Next

rxnux3r.regwrite "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\MSConfig\startupfolder",""

[JavaScript]

caranya: buka notepad lalu simpan scriptnya dengan extensi js

misal: Membuka Registry yang dikunci

var rxnux3r = WScript.CreateObject("WScript.Shell")

rxnux3r.RegWrite ("HKCU\\Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\System\\DisableRegistryTools", "0", "REG_DWORD")

-Registry Tools (alternatif regedit)

Ada banyak aplikasi alternatif untuk membuka registry windows misalnya: TuneUp Registry Editor, Sysinternal, Unlocker dsb. Jika sobat bisa membuat program sendiri akan lebih bagus lagi ^_^

- Administrative Tools

Sebenarnya merubah settingan dari administrative tools juga ikut merubah settingan registry. misalnya disable username in start menu di gpedit.msc (Group Policy Editor), serta setelah mengaktifkan software restriction policy di secpol.msc (Security Policy) maka kita bisa set level permission dari setiap software & string/key registry yang boleh diakses/tidak oleh user account, drive apa aja yang boleh exec/noexec, serta extensi apa aj yang diizinkan pada drive tertentu.

Sebenarnya ada banyak sekali settingan registry yang bisa dioprek, tapi terlalu panjang jika saya jabarkan settingan registry repair satu persatu disini. Oleh karena itu monggo silakan langsung download aj script Registry Repair yang sudah saya buat disini

Notes:

-Jika semua akses menuju registry telah diblokir, maka sobat bisa menggunakan "Offline NT Password & Registry Editor", yang nantinya bisa langsung membaca system.dat serta user.dat (tentunya dengan booting lewat CD atau usb)

-Jika tingkat kerusakan system sudah sangat parah barulah gunakan jurus pamungkas (install ulang ^_^)

BIOS Beep Code

noreply@blogger.com (rachmat) — Wed, 23 Dec 2009 00:50:00 +0000

Tentunya saat booting komputer, anda mendengar bunyi beep, nah masing2 beep tersebut mempunyai makna masing2 tergantung dari manufaktur pembuatnya.
Pada artikel kali ini saya akan sharing tentang arti bunyi beep pada BIOS Ami, Award .

Beep 1x pendek --> tidak ada masalah
Beep 1x panjang --> gangguan pada harddisk
Beep 1x panjang & 1x pendek --> gangguan pada mobo
Beep 1x panjang & 2x pendek --> gangguan pada VGA
Beep 3x panjang --> gannguan pada keyboard
Beep pendek terus-menerus --> gangguan pada power supply
Beep panjang terus-menerus --> gangguan pada memori

Untuk anda yg booting normal serta bisa masuk operating system tanpa ada kendala hardware apa pun namun tidak mendengar bunyi beep apa pun, anda tidak perlu cemas karena tidak semua mobo dipasang sound detector untuk bunyi beep.
Daftar Istilah:
-BIOS -> Basic Input Output System
-mobo -> motherboard
-VGA -> Video Graphic Array
-power supply -> sumber energi listrik (catu daya)

LTE versus WiMax

noreply@blogger.com (rachmat) — Thu, 17 Dec 2009 01:29:00 +0000

LTE (Long Term Evolution 4G)

Jaringan telekomunikasi generasi keempat (4G) Long Term Evolution komersial pertama di dunia hari ini diluncurkan di Stockholm, Swedia. Jaringan tersebut dibangun oleh Ericsson untuk operator TeliaSonera.

How about LTE versus WiMax?

LTE adalah teknologi komunikasi yang mampu mentransfer data dalam kecepatan tinggi. Untuk pita frekuensi sebesar 2.6 Ghz Kecepatannya mencapai 100 megabit per detik (Mbps) untuk downlink. Dengan latensi yang berkurang, pengguna bisa menikmati video definisi tinggi secara daring, video game daring, dan sebagainya dalam keadaan bergerak

WiMAX
WiMAX adalah singkatan dari Worldwide Interoperability for Microwave Access, merupakan teknologi akses nirkabel pita lebar (broadband wireless access atau disingkat BWA) yang memiliki kecepatan akses yang tinggi dengan jangkauan yang luas. WiMAX merupakan evolusi dari teknologi BWA sebelumnya dengan fitur-fitur yang lebih menarik. Disamping kecepatan data yang tinggi mampu diberikan, WiMAX juga merupakan teknologi dengan open standar. Dalam arti komunikasi perangkat WiMAX diantara beberapa vendor yang berbeda tetap dapat dilakukan (tidak proprietary). Dengan kecepatan data yang besar (sampai 75 Mbps) IEE 802.16e (2.6Ghz), WiMAX dapat diaplikasikan untuk koneksi broadband ‘last mile’, ataupun backhaul.

LTE versus Wimax
Bahas Yuk:
Parameter yg dibandingkan adalah Throughput, Coverage Area, Easy to implement (cheap infratructure cost) serta reliable data transmission.

1. Throughput
Okelah kalo begitu... okelah kalo beg beg.... ckckck, diatas kertas throughput LTE lebih unggul dari WiMax, Downlink yang diusung LTE katanya sih mampu melampaui WiMax yakni kisaran 100 Mbps, sementara WiMax kisaran 75 Mbps.
Keduanya menawarkan kemampuan rate transfer data maksimal hingga Gbps pada pita frekuensi kisaran 3.4 Ghz - 3.5 Ghz.

2. Coverage Area
Saya belum ada data akurat tentang coverage area dari LTE 4G, jadi lum bisa komeng banyak, namun jika diliat dari kemampuan downlinknya keduanya sama2 mempunyai range coverage area yg luas.

3. Easy to Implement
WiMax lebih easy to implement dibandingkan dengan infrastruktur generasi sebelumnya dari LTE yakni 3G , karena 3G infratrukturnya lebih kompleks serta butuh banyak node.
Sebenernya sih banyaknya node tergantung dari tingkat kepadatan pemukiman yg pake mobile, kondisi lingkungan terkait mudah atau tidaknya membangun BTS , max downlink, serta regulasi terkait izin pita frekuensi
Informasi terupdate dari antaranews.com, depkominfo sudah membolehkan upgrade pita frekuensi untuk proyek 3G menjadi 3.5G HSDPA pada kisaran 2.1 Ghz yg sebelumnya 1900 Mhz.
Lalu bagaimana dengan WiMax vs LTE?
Data detail teknis terkait kemudahan implementasi di lapangan saya belum taw (onwards), tapi jika diliat dari secara teori sih LTE punya downlink lebih baik dari WiMax. Itu artinya lebih irit node dibandingkan WiMax. Tapi faktanya perkembangan teknologi dari 2G , 3G , hingga generasi 3.5G, infrastrukturnya tetep komplex hanya saja tingkat komplexnya semakin berkurang seiring meningkatnya kemampuan data transfernya.
Infrastruktur LTE sepertinya akan mengadopsi pendahulunya juga, jadi kemungkinan infrastrukturnya tetep lebih komplex dibanding WiMax.

4. Reliable Data Transmission
Dengan Kemampuan Bandwith yang sama2 besar maka range data transfer pun bisa lebih jauh, sehingga kemungkinan lost of data akan berkurang. Keduanya sama2 reliable serta mendukung implementasi IPv6.

Kesimpulan:
Ditinjau dari kemampuan transfer rate data pada downlink LTE lebih unggul dari WiMax. (beda tipis lah seperti valentino rossi dengan casey stoner ^_^ )
Ditinjau dari easy to implement, WiMax lebih unggul
Cost efektif ditinjau dari bandwith lebih unggul LTE dari WiMax,
Cost efektif ditinjau dari infrastruktur lebih unggul WiMax dari LTE.
WiMax is great 3G killer but LTE 4G is great competitor for WiMax

Notes:
Ini barulah awal dari WiMax, seperti halnya 3G yg berkembang jadi LTE 4G, WiMax juga akan mengalami perkembangan teknologi, akan kah kedepannya muncul WiMax the killer of LTE?? kita tunggu saja perkembangannya... oke coy??

Istilah:
Downlink -> link dari satelit ke bawah ( stasiun penerima/ ground station/ receivers)
