  • 之所以是2.x的最新版,而不是最新版,原因有很多,不过最大的原因还是兼容问题,以及以及软件库的可用量问题。
  • 显然2.x就像是Windows,而3.x就像是linux(当然这个比喻或许有点不恰当。linux的应用对比Windows来说不会少太多。)
  • 虽然性能优异,但是3.x的应用库还是略显稀少多数第三方库都还在使用2.x版本的Python。


1. 下载:

$ wget -c

2. 解压

$ tar zxvf Python-2.7.9.tgz

3. 安装

# cd Python-2.7.9 && ./configure  && make && make install

1. 注意,这个是覆盖安装,如果有更多老版本需求,建议在configure 后面添加路径参数,如:–prefix=/usr/python27

  2. use root to install it! 

4. 看看成果吧。python v2.7.9

python -V

Install PIP

Angry IP Scanner: Scan IP Addresses And Ports For Analyzing Networks

Angry IP Scanner, also known as ipscan, is an open source network scanning tool that can be used to scan the ip addresses and ports on your network. It supports Linux, Windows, MAc OSX and other platforms. It has designed to be fast and simple to use. It has been used by Network administrators on almost all organizations.


- Lightweight and cross-platform.
– Scans ip addresses in any range.
– Doesn’t require any installation
– Check for ip address if it is alive.
– Resolves hostnames, determines ip addresses and scans ports.
– Multi-threaded support to speed up scanning process.


As i mentioned before, we don’t have to install it. All we need is our system should have installed with Oracle java or openjdk. Just download the ipscan jar file and run it with command:

# java -jar ipscan.x.x.jar

Also you can install it if you wish. Just download deb/rpm packages and install as described below.

Hence all modern operating system comes with openjdk in their default repositories, we don’t have to worry about openjdk installation.

First install openjdk using command:

On Debian/Ubuntu:

$ sudo apt-get install openjdk-7-jdk


# yum install java-1.7.0-openjdk

Then grab Angry IP Scanner latest version from here depending upon your platform and  architecture.

After downloading it, go to the directory where you have downloaded and install it using command:

On Debian/Ubuntu:

$ sudo dpkg -i ipscan_3.2.1_*.deb


[[email protected] ~]# rpm -Uvh /ipscan-3.2.1-*.rpm

Launch Angry IP Scanner

After installing, launch it either from Menu or Dash. At the first launch, you’ll pleased with Getting Started screen. You can read it by clicking on the Next button or click Close to exit Getting Started screen.

IP Range - Angry IP Scanner _001By default, your local ip address is selected. You can specify other ip addresses as well to start scan.

IP Range - Angry IP Scanner _002

Scan Local System

Let us start with local system ip address. Click Start to scan. After a couple of seconds, you will get the Scan Statistics like below.

Scan Statistics _003To view the hostname, ports of the system, just double click on the ip address. You will get the details as shown here.

IP address details _006Scan ‘n’ number of  system

In the above test, we scanned only single system, i.e I entered the the same ip address on IP Range boxes. Now let me scan some remote systems on my network. Say for example, let us scan systems whose has ip address between to

Enter ip addresses and in the from and to column boxes of IP Range and click Start button.

Now you’ll see the list of alive hosts in the range of network that you have entered.

IP Range - Angry IP Scanner _007As you see in the above statistics, i have two hosts running on my network. Pretty easy, isn’t?

More Commands

Not only it displays the alive hosts in your network, also it will allow you to manage the remote systems. Let us see how.

Let us say you want to ssh to a system on your network. Just right click on the ip address, go to Open and select SSH. Alternatively you can open it from Menu bar. Click on the Commands button on the menu bar and go to Open -> SSH.

Menu_010A new small window will appear and will ask the password the password to log in to the system. Enter it and you’re in business. Now you should be able to ssh to your remote system.

sk@server:~_011Be mindful that, your remote server have SSH installed, otherwise you won’t be able to connect via ssh. Like this way, you can do various commands such as ftp, trace route, telnet etc.

While testing this app, i found myself, it will be quite useful for Network administrators. It is simple, but powerful and it does the job as advertised. Hope it will be useful for you.

Good luck!

How To Add Swap On Linux

Swap is a type of filesystem and is a virtual memory. Whenever your RAM is full, your operating system will look for further memory in your swap space. For this reason, you reserve some part of the hard disk to create a swap partition.


Identifying Current Swap Space Usage

[[email protected] ~]# cat /proc/swaps
Filename          Type          Size          Used        Priority 
/dev/sda7     partition        1951740         4                -1

Alternatively, use the swapon command:

[[email protected] ~]# swapon -s
Filename            Type           Size          Used      Priority
/dev/sda7          partition      1951740           4            -1

Finally, the free command may also be used:

[[email protected] ~]# free
                      total       used           free     shared     buffers     cached
Mem:            895112     721656    173456      0         36592      310156
-/+ buffers/cache:         374908    520204
Swap:           1952736         4    1952732

Adding a Swap File

Additional swap may be quickly added to the system by creating a file and assigning it as swap. This is achieved as follows. The following dd command example creates a swap file with the name swap with a size of 1Gb.

Create the swap file using the dd command:

[[email protected] ~]# dd if=/dev/zero of=/swap bs=1M count=1024
1024+0 records in
1024+0 records out
1073741824 bytes (1.1 GB) copied, 17.4283 s, 61.6 MB/s

Configure the file as swap

Change the permission of the swap file so that only root can access it

[[email protected] ~]# chmod 600 /root/swap

[[email protected] ~]# mkswap /swap
 Setting up swapspace version 1, size = 1048572 KiB
 Enable the newly created swapfile :

[[email protected] ~]# swapon /swap

Finally, modify the /etc/fstab file to automatically add the new swap at system boot time by adding the following line:

# cat /etc/fstab
/swap    none    swap    sw    0 0

Once the swap space has been activated, verify that it is in use using the swapon –s command:

[[email protected] ~]# swapon -s
Filename      Type        Size       Used    Priority
/dev/sda7    partition   1951740  142884      -1
/swap            file         1048572       0         -2
[[email protected] ~]# free -k
                 total       used       free      shared       buffers      cached
Mem:        895112     828484      66628          0        2144        539552
-/+ buffers/cache:     286788      608324
Swap:       3000312    142876      2857436

If you don’t want to reboot to verify whether the system takes all the swap space mentioned in the /etc/fstab, use following to enable or disable swap.

[[email protected] ~]# swapoff -a
[[email protected] ~]# swapon -a

De-activate the additional swap space at any time using the swapoff command as follows:


[[email protected] ~]# swapoff /newswap

Some Useful Linux Screenshot Tools

Hi guys,

There are many Linux screenshot tools out there, so I decided to compile a list with some of the tools I have used and have experience with. The following tools are free and they will help you to capture your computer screen. In this list you will find all kinds of screenshot apps for Linux, from simple to advanced ones such as shutter.


I cannot hide the fact that this is one of my favorite apps for taking screenshots on my Linux machine. In my opinion, it is a must for every Linux technical blogger that want to craft nice pictures for his/her articles.

Shutter is an open source advanced screenshot app that can take a screenshot of a specific area, window, your whole screen, or even of a website. One of many reasons that I like to use it is the fact that the shutter has an editor which can be used to modify and apply effects to my screenshots.

After you have captured your screen you can use the shutter’s editor to add text, arrows, rectangles, ellipses, auto-increment shapes and apply many nice effects to your screenshot.

I am very happy that such a tool exists. It makes my job easier and my screenshots look good.  You can learn how to take and edit screenshots with shutter here.


HotShots is an application for capturing screens and saving them in a variety of image formats as well as adding annotations and graphical data (arrows, lines, texts,…). You can also upload your creations to the web (FTP/some web services).

For installation and usage instructions, please visit our previous article here.


Gnome-Screenshot is the best tool for taking screenshots in a very fast way. It is very simple to use, has a very nice looking user interface and the right features needed to capture computer screen. This tool was part of the gnome-utils package, but was split into its own package in 2011.

Unlike shutter, Gnome-Screenshot does not have an editor, but you can still apply some effects such as  Drop Shadow and Border. If you are looking for a very simple tool that does the job the use Gnome-Screenshot.

Gnome-Screenshot can be used to grab the whole desktop, grab the current window or select an area to grab. You can also  take a screenshot after a delay of seconds which you can specify with the Grab after a delay of option.

The good thing is that Gnome-Screenshot comes installed by default in Ubuntu Linux operating system. You can find and launch it by going to Applications, Accessories, Screenshot.


gpe-screenshot is a screenshot application for GPE and one of the simplest app I have ever used in my all Linux life. On debian based systems it can be installed via the apt-get command like shown below.

sudo apt-get install gpe-screenshot

Unfortunately, this screenshot app does not have many options and you can’t do much with it. It takes a screenshot of your whole computer screen and can save it locally or upload to

After the installation is finished, you can easily launch the gpe-screenshot application by going to Applications, Graphics and thenTake Screenshot.

The app will capture your computer screen immediately after its launch and after will ask you if you want to save it in any of the local folders on your machine or upload it to

The gpe-screenshot tool can be very useful when you want to share your screenshots with friends or want to show something to other people in online forums.


Ksnapshot is another useful screen capture app, with many useful features such as Snapshot delaySeveral Capture Modes and simple effects. It does not include an editor, but allows you to send your screenshots to image viewers and image editors such asGimp.

Ksnapshot has the following capture modes:

- Full Screen
– Freehand Region
– Window Under Cursor
– Section Of Window
– Rectangular Region


You learned about five screenshot tools, their features and options. Use the screenshot app that does the job for you. For me,shutter is the best, it does not mean it should be the same for you.


I take screenshots, edit them and share them in articles to my unixmen readers. Most of the time I use the shutter screen capture app, but sometimes I find myself using the Gnome-Screenshot tool.
