\WINDOWS\SYSTEM32\CONFIG\SYSTEM corrupted

This is common problem in Windows XP that disallow user to boot onto XP. Probably there are files corrupted due to improper shutting down or power failure.

What i did to solve is, put on Windows XP CD and boot into CD mode. Then, wait until it will prompt with few options, like for installing fresh windows and repair. Choose option to repair by press 'r'.

Next step, you will see command line interface (CLI). It will show an option for partition (i.e C: or D: ). Just choose the number where you have installed the windows. In my case I press 1 for partition C. Then, it will ask for administrator password. If you did not set any password for admin, just leave it blank and press ENTER.

You will see like this.

C:\WINDOWS>

Here, I run check disk instead of copying corrupted files.

C:\WINDOWS>chkdsk c: /P /R

Note that c: is the partition drive of the installed windows. See the manuals from run:

'chkdsk /?'

Then wait for about 30 minutes (according to size) until 100% completed. After finish type 'exit' to reboot

Thats all, hope it will solve yours =)

Time is Moving ..

Now i realize that i'm about to finish my 6-month internship and start a job at new company..hope everything will be always fine..amin :)

Please explain this

Windows Media Center VIRUS: what to do?

Last weekend my friend come to my house and bring his new laptop with new problem. All programs cannot be opened because registry is corrupted. I try to open any program, includes mozilla, yahoo messenger,cmd and regedit, but this crappy windows 7 always redirect to open Windows Media Center. All programs' icon turn to windows media center. I try to ask google and it is actually a virus. What we need is repair the registry that fooling windows user.

The solution is:

download this registry file HERE, and double click on it.

or copy paste these two lines into a file and save it file.reg. Then, double click it.

Windows Registry Editor Version 5.00

[-HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.exe\UserChoice]

Then reboot to restore your icon as normal.

Hopefully this will help u :)

Intel Dual Core Processor: Core 2 Duo vs Core i3 (new generation)

My head has been playing with the difference between core 2 duo (older) and core i3. Then, I start exploring Intel website and find what i3, i5 i7 are all about.

In this post, I simply compare this two processors. I referred to the site on core 2 duo and core i3 specification. Both are similar in term of processor number (2 cores).

The main differences are the number of threads and cache type.

Older dual core processor doesn't enable thread for each core as compared to current generation such as i3, i5 and i7. Core i3 has the capability to run dual thread on each core, thus total threads number can run in core i3 is 4 threads. Same as goes to other processor in this family, i7 has up to 8 threads can be ran on (each 2 or 4 core).

Core i3 used new smart cache (L3 cache) instead of L2 cache, as defined by Intel:

"Smart Cache is Intel’s performance-maximized data storage, which allows each processor core to dynamically utilize up to 100% of available cache and obtain data from the cache at higher throughput rates"

For gamers, here is a benchmark i found.

Fedora: Install & configure Net-SNMP running on IPv6

I've install net-snmp on my fedora machine for 'secret' purpose :P

Here are some basic tutorial but it works for me and perhaps all fedora user. I've experienced some errors if directly install the net-snmp. Thus, I try to install perl first (latest version) before installing and afterwards I didn't face any error to install.

Step 1: Installing Perl from source

Download tar ball (.tar.gz) of the latest version with type (maint) here

login as root, go to directory where the tar ball is located, extract and go inside directory

$ su

# tar xzvf perl-version.tar.gz

# cd perl-version

now, we configure (with default setting) to confirm with your platform

# ./Configure -de

compile and install

# make && make install

Note that it won't be installed if there is an error

if it is successfully installed, try . .

$ perl -v

output will be the version of newly installed perl. In my case:

This is perl 5, version 12, subversion 1 (v5.12.1) built for i686-linux

Step 2: Installing net-snmp from source

Go to net-snmp page and download source file (.tar.gz) under 'current release'. Same thing, extract the tar file

# tar xzvf net-snmp-version.tar.gz

# cd net-snmp-version

Then, configure using several option (press enter for each prompt)

# ./configure --enable-ipv6 --with-transports="UDP UDPIPv6" --with-libs=-lpthread --with-perl-modules

finally compile and install

# make && make test && make install

remember, if any error occurs installation won't finish

Step 3: snmpd configuration file

Go to snmp directory

# cd /usr/local/share/snmp

Then, we can create snmpd.conf file using this command

# snmpconf

Would you like me to read them in? Their content will be merged with the

output files created by this session.

Valid answer examples: "all", "none","3","1,2,5"

Read in which (default = all): none

next . .

I can create the following types of configuration files for you.

Select the file type you wish to create:

(you can create more than one as you run this program)

1: snmpd.conf

2: snmptrapd.conf

3: snmp.conf

Other options: quit

Select File: 1

Lastly, type 'finished' and 'quit'. You will get output like this

The following files were created:

snmpd.conf

Now, edit this file and replace with all content posted here

# gedit snmpd.conf

and add this line after this line '# sec.name source community'

[...]

com2sec6 local ::1 public

[...]

save the file and close.

Now, Run snmpd first just on udp with IPv6 on port 161 (as root)

# snmpd udp6:161

Then, try snmpwalk (You should have IPv6 configured)

# snmpwalk -v 1 -c public 'ipv6:[::1]' IP-MIB::ipAdEntIfIndex

Output will be somehow like this

IP-MIB::ipAdEntIfIndex.10.1.27.140 = INTEGER: 3

IP-MIB::ipAdEntIfIndex.127.0.0.1 = INTEGER: 1

If you got this, so i think it works ;)

Where is my installed Wireshark?

So this is what happen this morning where we installed wireshark on my Fedora 12 PC. It is successfully installed but executable file doesn't appear anywhere.

To install:
yum install wireshark

What you have to do is just further install:

yum install wireshark-gnome

Bye2 :D

Net-SNMP Tutorial

Just followed good tutorial to configure Net-SNMP >> click here

Anyway, I experienced error while 'make' where  I got this error >>/usr/bin/ld: cannot find -lperl

I find the solution here

First, locate libperl.

Output:

/usr/lib/libperl.so.5.10
/usr/lib/libperl.so.5.10.0

...

(or similar)

Create soft link;

sudo ln -s /usr/lib/libperl.so.5.10 /usr/lib/libperl.so

Make sure the link is in the /usr/lib **same directory with the link point. 

That's all. Thank you.

Streamyx: Sharing Internet on Fedora 12

I'm using streamyx for Internet connection at home. I've a laptop with an Ethernet card and a wireless card. Then, I started to google on how to share internet connection with other laptops using wireless connection since my LAN card is occupied with streamyx cable.

For setting up my machine as a gateway, it quite similar to previous post here, but it can simply be done by configuring firewall. Then, we can create an Ad-Hoc connection so that other machines (client) can simply connect to my laptop without the need of access point. In addition, in order to automatically configure IP address, gateway and DNS server address on client machine, we can set up DHCP server in the laptop (gateway machine). Following are the steps for make it works :

Note that all configuration is done on gateway machine.

Step 1: Connect to streamyx

Right-click on network manager applet, then choose 'Edit Connections..'

Select DSL tab and click 'Add' to add new connection. Then rename connection name to 'streamyx' or anything you want. Enter your username, password and service as shown in picture below. Tick connect automatically if want to allow connection on startup. Click 'Apply' to finish

Click on applet again, and now streamyx connection should be appear under 'Wired Networks'. Select to connect.

Step 2: Configure Firewall (from this step, all need to be done as root)

Open terminal and type

$ su

# system-config-firewall

Select 'Masquerading' and tick as bellow (thanks to KageSenshi)

Step 3: Setup DHCP server

First, install dhcpd (in fedora 12, dhcp package is using version 4)

# 'yum install dhcp

Check your DNS server to be used in dhcp configuration file

$ less /etc/resolv.conf

Output should be appear like this

# Generated by NetworkManager

nameserver 204.177.0.3

nameserver 204.177.1.12

Then, edit dhcpd configuration file (use familiar text editor such as gedit, vi or nano)

$ su -c 'gedit /etc/dhcp/dhcpd.conf'

Then, make it similar as bellow and match the address of DNS at 'option domain-name-servers'

# beginning of file

default-lease-time 86400;

max-lease-time 604800;

authoritative;

ddns-update-style interim;

option domain-name-servers 204.177.0.3

,204.177.1.12

;

subnet 192.168.1.0 netmask 255.255.255.0 {

range 192.168.1.1 192.168.1.5; # only 5 person can connect

option broadcast-address 192.168.1.6;

option routers 192.168.1.1; # gateway address

}

# end of file

Step 4: Create an Ad-Hoc connection

Enable wireless connection, then select 'Create New wireless Network'

Choose any wireless security you want or simply choose none. Click 'Create' to finnish.

Again right-click on the network manager applet and choose 'Edit Connections'. Then, under 'Wireless' tab, select your connection name and edit as follow

Click on applet, and select 'Connect to Hidden Wireless Network' and connect.

Finally, restart dhcp server

# sudo service dhcpd restart

Note that you need to connect to the created ad-hoc connection first (in my case, it is 'anyname') before you can start dhcp server.

Now, everyone near to you can see you Ad-hoc connection. Configure client's IP address using 'automatic configuration'. Once they connect to your ad-hoc connection through WiFi, they can surf to internet and facebooking all the time :P

IIUM FM

I'm IIUM student :) and I'm glad that IIUM has it own radio, which is broadcasting over the Internet. Users could simply go to this page http://livestream.iiu.edu.my/iiumfm/ and it will stream the radio using supported player in web browser. Nice huh?.. Hehe.

Beside that, for Linux user, you can simply use Rythmbox as follow:

Step 1: Make sure plugins are installed

ubuntu user,

$ sudo apt-get install ubuntu-restricted-extras

and fedora,

$ sudo yum install gstreamer-plugins-ugly gstreamer-plugins-bad gstreamer-ffmpeg

It is also necessary to install a bunch of codecs in here

Step 2: adding link

open your rythmbox, go to menu 'Music',click on 'New Internet Radio Station' and add this url

mms://livestream.iiu.edu.my/iiumfm

Then, go to side bar on Radio, then double click on the new added link.

That's it. Enjoy ;)

Fedora: Change Root Directory of Httpd

I recently try to install apache on fedora 12. I need to change the root directory to ease me editing file and avoiding permission. It is quite different when I was configuring on ubuntu. After read through several forums I come to this post. So, I won't be crazy for the next time.. haha

The default root directory is at /var/www/html. In my case, I want to change it to /home/user1/web.

Step 1: Edit apache configuration file (as root)

# gedit /etc/httpd/conf/httpd.conf

Find these two lines

DocumentRoot "/var/www/html"

...

...

#

# This should be changed to whatever you set DocumentRoot to.

#

<Directory "/var/www/html">

Then, change to

DocumentRoot "/home/user1/web"

...

...

#

# This should be changed to whatever you set DocumentRoot to.

#

<Directory "/home/user1/web">

Save and close this file.

Step 2: Changing permission

# chmod 711 /home/user1

# chmod -R 755 /home/user1/web

This step is necessary since in fedora, httpd process will be executed by user 'apache', thus permission need to be change.

By default, the permission for each user directory is drwx------, so that other users can't access to files in this directory and its subdirectories.

# setsebool -P httpd_enable_homedirs 1

# chcon -R -t httpd_sys_content_t /home/user1/web

Note: httpd by default is not allowed to access users home directories, see this page

Step 3: Restart apache

# service httpd restart

Hope this will help a little bit :)

Setting Up LAMP + memcached on Ubuntu Server 9.10

This post will show a guide on how to setup LAMP with memcached on three machines. Perhaps this will help us on writing technical report..huahuha

We are currently running our performance test on our web and database server using memcached. The test is used to monitor the cpu and memory usage using cacti. Thanks to khairina for SNMP and cacti configuration :)

We have installed LAMP server in two 64-bit machines, whereas 1 machine running apache2 with php5 while another one running MySQL 5.1.

We also have a dedicated memcached server. Since we are using php5, thus we chosen php as our memcached client.

Then it can be simply tested using 'ab' (apache bench).

Step 1: Setting up Web Server (192.168.0.101)

Installing apache2 and php5

$ sudo apt-get install apache2 php5 libapache2-mod-php5

Note: In ubuntu, php5 will use php5-prefork by default

Installing MySQL module for php5

$ sudo apt-get install libapache2-mod-auth-mysql php5-mysql

Then, edit php configuration file to add mysql extension

$ sudo vi /etc/php5/apache2/php.ini

Then add this line

extension=msql.so

Installing memcache module for php5

$ apt-get install php5-memcache

Then, edit php configuration file to add memcached extension

$ sudo vi /etc/php5/apache2/php.ini

Then add this line

extension=memcache.so

To ease us in locating our php file on our web server, we have changed the default location.

Edit /etc/apache2/sites-available/default. Don't forget to backup it first. (use gedit,vi or nano)

$ sudo vi /etc/apache2/sites-available/default

Then, find this two lines.

DocumentRoot /var/www/

Edit it into preferred directory, so it become

DocumentRoot /home/username/web/

Make sure the directory exists

$ mkdir /home/username/web/

Restart apache2

$ sudo /etc/init.d/apache2 restart

Now, we can create our php code inside the web directory.

Step 2: Setting up Database Server (192.168.0.102)

Installing MySQL server 5.1

$ sudo apt-get install mysql-server

Then edit mysql configuration file to bind address so it can be connected from any machines

$ sudo vi /etc/mysql/my.cnf

Edit this line

bind-address = 127.0.0.1

to (MySQL server IP address)

bind-address = 192.168.0.102

then, restart mysql server

$ sudo /etc/init.d/mysql restart

Add a user to enable to mysql client connect from different host (as mysql server) see the manual here

Step 3: Installing Memcached (192.168.0.103)

Get the latest memcached source file (current version is 1.4.4) that can be download from this site. Then, follow this guide

Or simply install using apt-get. In ubuntu 9.10 the memcached version is 1.2.8

$ sudo apt-get install memcached

Create a file, put the php code below and save it as index.php into /home/username/web directory (or /var/www/ if haven't do any changes)

<?php phpinfo(); ?>

Open web browser the type http://webserver_ipaddress/index.php. Then, the memcached module for php5 can be found in this page as figure below

Now, we can test our web and database server :D

SNMP & Cacti Configuration (PART 2)

SNMP configuration updated. Previously, I have posted SNMP & Cacti Configuration. I want to add some additional necessary information to configure which I have done.

Firstly I checked my SNMP if it's working or not:

$snmpwalk -v 1 -c public localhost IP-MIB::ipAdEntIfIndex

It suppose to return your ip as output like below:

In my case, SNMP is not working and return many different errors. What I have done to solve the problem is just edit snmpd configuration file (snmpd.conf). Below is my snmpd.conf (/etc/snmp/snmpd.conf), you could simply copy paste and try to your PC. (Copy the original file first so you have backup if something happen) -- I put the lines you have to check in red.

##########################################

# EXAMPLE.conf:

# An example configuration file for configuring the ucd-snmp snmpd agent.

#

##########################################

# This file is intended to only be an example. If, however, you want

# to use it, it should be placed in /etc/snmp/snmpd.conf.

# When the snmpd agent starts up, this is where it will look for it.

#

# You might be interested in generating your own snmpd.conf file using

# the "snmpconf" program (perl script) instead. It's a nice menu

# based interface to writing well commented configuration files. Try it!

#

# Note: This file is automatically generated from EXAMPLE.conf.def.

# Do NOT read the EXAMPLE.conf.def file! Instead, after you have run

# configure & make, and then make sure you read the EXAMPLE.conf file

# instead, as it will tailor itself to your configuration.

# All lines beginning with a '#' are comments and are intended for you

# to read. All other lines are configuration commands for the agent.

# PLEASE: read the snmpd.conf(5) manual page as well!

##########################################

# Access Control

##########################################

# YOU SHOULD CHANGE THE "COMMUNITY" TOKEN BELOW TO A NEW KEYWORD ONLY

# KNOWN AT YOUR SITE. YOU *MUST* CHANGE THE NETWORK TOKEN BELOW TO

# SOMETHING REFLECTING YOUR LOCAL NETWORK ADDRESS SPACE.

# By far, the most common question I get about the agent is "why won't

# it work?", when really it should be "how do I configure the agent to

# allow me to access it?"

#

# By default, the agent responds to the "public" community for read

# only access, if run out of the box without any configuration file in

# place. The following examples show you other ways of configuring

# the agent so that you can change the community names, and give

# yourself write access as well.

#

# The following lines change the access permissions of the agent so

# that the COMMUNITY string provides read-only access to your entire

# NETWORK (EG: 10.10.10.0/24), and read/write access to only the

# localhost (127.0.0.1, not its real ipaddress).

# For more information, read the FAQ as well as the snmpd.conf(5)

# manual page.

##########################################

# First, map the community name (COMMUNITY) into a security name

# (local and mynetwork, depending on where the request is coming

# from):

# sec.name source community

com2sec local localhost public

com2sec mynetwork 10.101.95.0/24 public

##########################################

# Second, map the security names into group names:

# sec.model sec.name

group MyROSystem v1 paranoid

group MyROSystem v2c paranoid

group MyROSystem usm paranoid

group MyROGroup v1 local

group MyROGroup v2c local

group MyROGroup usm local

group MyRWGroup v1 mynetwork

group MyRWGroup v2c mynetwork

group MyRWGroup usm mynetwork

##########################################

# Third, create a view for us to let the groups have rights to:

# incl/excl subtree mask

view all included .1 80

view system included .iso.org.dod.internet.mgmt.mib-2.system

##########################################

# Finally, grant the 2 groups access to the 1 view with different

# write permissions:

# context sec.model sec.level match read write notif

access MyROSystem "" any noauth exact system none none

access MyROGroup "" any noauth exact all none none

access MyRWGroup "" any noauth exact all all none

#--------------------------------------------

#############################################

# System contact information

# It is also possible to set the sysContact and sysLocation system

# variables through the snmpd.conf file. **PLEASE NOTE** that setting

# the value of these objects here makes these objects READ-ONLY

# (regardless of any access control settings). Any attempt to set the

# value of an object whose value is given here will fail with an error

# status of notWritable.

#Editing this value is optional, i dont do any changes

syslocation Unknown (configure /etc/snmp/snmpd.local.conf)

syscontact Root (configure /etc/snmp/snmpd.local.conf)

End changes. Leave code below this line as it is

################################################

After edit this file, save it. Then restart SNMP. Make sure you restart.

$sudo service snmpd restart

Then, do check again.

$snmpwalk -v 1 -c public localhost IP-MIB::ipAdEntIfIndex

That's all. :)
