MPLS BENEFITS

02:40:00 ITExam_Blog No comments

1) faster switching then IP as IP Forwarding is based on IP routing table search each address is 4 octets length and can cause some time to calculate

2) Core free from BGP as the MPLS is based on label switching there is no need any more for core routers to participate in the BGP network and only Edge routers need to be BGP aware. this is a huge memory and utilization saving.

3) MPLS TE Traffic Engineering is one of the major benefits as it is allowing you to have better path selections and it have a very good mechanism called FRR Fast ReRouting and this is allowing to re-route traffic from and unavailable router in a really fast speed of less then 50ms, and this is allowing us to build a stable and reliable Data and VoIP Network as you know less then 50ms loss will still keep the Voice Call Up, if it is more then that the call will be dropped. so this feature allows us in a good planed network to give us near PSTN solution.

4) MPLS VPN is another major benefit as it is reducing manageability and introducing simplicity to the client. before if the client wanted to create a VPN for his offices network he needed to either create tunnels between all his offices creating a lot of configuration and complex design when there are more then 4 branches or he needed to ask the provider to create all this VPN's and relay on his network design. but with MPLS VPN he simply need to make a Connection between his Customer Edge Router and Provider Edge Router.

Installing PostgreSQL

17:30:00 ITExam_Blog No comments

This is a quick guide to installing PostgreSQL on a Linux based system. We need to get this up and running before we can write PHP scripts to talk to the database. We need to install PostgreSQL before we can install PHP (since we need the PostgreSQL header files).

This is a little more complicated than installing Apache.

The best bet is to install from packages since this will make things easier, both now and for upgrades.

If you decide to install from source code, you'll need to create a user and compile the source.

Create a PostgreSQL user (you'll need root access). This is who owns the system. I use the "postgres" user and group, you can use something different but it's best to keep it related to the package.

See your system documentation on how to do this (hint - man useradd). Give the user a home directory of /usr/local/pgsql as this is where PostgreSQL defaults to when it installs.

Once all that is done, untar the source:

$ tar -zxf postgresql-.tar.gz (if you got the gzipp'ed version);
or
$ tar -xjf postgresql-.tar.bz2

Jump into the directory:

$ cd postgresql-

(replace with the version you downloaded from the website).

Again, configure has a lot of help:

$ ./configure --help

We'll just install into /usr/local/pgsql and leave the rest as-is:

$ ./configure --prefix=/usr/local/pgsql

Next we have to make it (this will take a while, it takes longer than Apache):

$ make

You will get a line:
All of PostgreSQL successfully made. Ready to install.

when everything is finished.

You'll need to log in as root to do the rest:

$ su -

Go back to the postgresql directory and do:

# make install

PostgreSQL doesn't allow root to start up the server for security reasons, so next you'll have to change the owner of the files:

# chown -R postgres:postgres /usr/local/pgsql

Change to the postgres user:

# su - postgres

Then, change to /usr/local/pgsql:

$ cd /usr/local/pgsql

We need to initialize a database cluster:

$ bin/initdb -D ./data

This will create a /usr/local/pgsql/data directory and initialize it ready for startup and use.

As usual, you can view options by using the --help switch:

$ bin/initdb --help

Then you can start:

$ bin/pg_ctl -D ./data -l data/logfile start

Now that postgresql is started, we need to create a database and another user before we go any further.

You should use a separate database for each of our projects, it's not essential though - it just makes things a little cleaner and easier to understand.

You should also use separate users for each database. This keeps everything separate and 'project a' won't be able to modify any of 'project b's data.

To create a new user in postgresql, it's pretty simple:

$ /usr/local/pgsql/bin/createuser

and follow the prompts - pretty simple :)

The new user should not be able to create new databases or create new users.

To create a database, it's a little different.

$ /usr/local/pgsql/bin/createdb --owner=username databasename

We have to set the owner of the database when we create it, otherwise the 'postgres' user owns it and then we have to grant access to allow our new user to access it.

Now that that's all done, log out of the postgres user, so we're back as root. In the postgres directory, the contrib/start-scripts/ directory has a few system start up scripts.

Follow the instructions in the relevant one to install a start-up script so postgres will start when your system does.

More detailed installation instructions are in the INSTALL file or by going to the PostgreSQL website http://www.postgresql.org/docs/ and going to the right version for you.

Use Notepad to Create a Log File

09:14:00 ITExam_Blog No comments

SUMMARY

Microsoft Notepad is a word processing tool included with Windows and is installed by default under the Accessories program group. You can use it to create a log-type file that adds the current date and time each time the Notepad file is opened. This article describes how to create a log file with Notepad.

MORE INFORMATION

To create a log file in Notepad:

1.	Click Start, point to Programs, point to Accessories, and then click Notepad.
2.	Type .LOG on the first line, and then press ENTER to move to the next line.
3.	On the File menu, click Save As, type a descriptive name for your file in the File name box, and then click OK. When you next open the file, note that the date and time have been appended to the end of the log, immediately preceding the place where new text can be added. You can use this functionality to automatically add the current date and time to each log entry.

How to Disable Security Center Alerts

19:08:00 ITExam_Blog No comments

If you're running Windows XP Service Pack 2 (SP2) Windows Security Center should tell you the status of your antivirus software, firewall, and automatic updates. Security Center will alert you if your antivirus is out of date or turned off, firewall is turned off, or if Automatic Update is not turned on.

If you have received multiple alerts and would like to turn notifications off, you can disable the antivirus, firewall, or automatic update alerts.

Note You should only disable these alerts if you are an expert user. If you are in the process of updating or installing software you may also want to temporarily disable alerts, but please be sure to turn alerts back on so Windows can keep your status up to date.

To turn off Security Center alerts

1.	Click Start and then click Control Panel.
2.	Double-click Security Center.
3.	In the Security Center, under Resources, click Change the way Security Center alerts me.
4.	In the Alert Settings dialog box, clear the Firewall, Automatic Updates, or Virus Protection check boxes, and then click OK.

When you use this procedure, the Security Center still displays your status, but does not send you alerts.

Note If your computer is part of a domain (a group of computers on a network), your security settings are typically managed by your network administrator. In this case, the Security Center does not display your security status or send alerts.

Mount partition with ntfs file system

08:40:00 ITExam_Blog No comments

Introduction

Purpose of this article is to provide to reader step by step guide, how to mount partition with NTFS file system on Linux operating system. This article consist of two parts:

mount NTFS file system read only access
mount NTFS file system with read write access

Mount NTFS file system with read only access

NTFS kernel support

Majority of current Linux distributions support NTFS file system out of the box. To be more specific, support for NTFS file system is more feature of Linux kernel modules rather then Linux distributions. Lets check if we have NTFS modules installed.

ls /lib/modules/2.6.18-5-686/kernel/fs/ | grep ntfs

root@ensit~# ls /lib/modules/2.6.18-5-686/kernel/fs/ | grep ntfs
ntfs
root@ensit~#

NTFS module is presented. Lets identify NTFS partition.

Identifying partition with NTFS file system

One simple way to identify NTFS partition is:

fdisk -l | grep NTFS

root@ensit~#fdisk -l | grep NTFS
/dev/sdb1 * 1 261 210456 7 HPFS/NTFS
root@ensit~#

There it is: /dev/sdb1

Mount NTFS partition

First create mount point:

mkdir /mnt/ntfs

Then simply use mount command to mount it:

mount -t ntfs /dev/sdb1 /mnt/ntfs

root@ensit~#mkdir /mnt/ntfs
root@ensit~#mount /dev/sdb1 /mnt/ntfs
root@ensit~#cd /mnt/ntfs
root@ensit~#ls
test
root@ensit~#

Now we can access NTFS partition and its files with read write access.

Mount NTFS file system with read write access

Mounting NTFS file system with read write access permissions is a bit more complicated. This involves installation of addition software such as fuse and ntfs-3g. In both cases you probably need to use you package management tool such as yum, apt-get, synaptic etc.. and install it from your standard distribution repository. Check for packages ntfs-3g and fuse.

We take the other path which consists of manual compilation and installation fuse and ntfs-3g from source code.

Install addition software

Fuse Install

Download source code from: http://fuse.sourceforge.net/

wget http://easynews.dl.sourceforge.net/sourceforge/fuse/fuse-2.7.1.tar.gz

Compile and install fuse source code:

Extract source file:

tar -xzvf fuse-2.7.1.tar.gz

Compile and install

cd fuse-2.7.1

./configure --exec-prefix=/; make; make install

root@ensit~#ls
fuse-2.7.1.tar.gz
root@ensit~#tar -xzvf fuse-2.7.1.tar.gz
root@ensit~#cd fuse-2.7.1
root@ensit~#./configure --exec-prefix=/; make; make install

ntfs-3g install

Download source code from: http://www.ntfs-3g.org/index.html#download

wget http://www.ntfs-3g.org/ntfs-3g-1.1120.tgz
