Install JDK 7 on Ubuntu

Install JDK 7 on Ubuntu

Task: Install JDK 7 on Ubuntu desktop.
Problem 1: Java version 7 is not available from Ubuntu repositories for your Ubuntu version (prior to 11.10 Oneiric). You don’t see it neither via "Ubuntu Software Center" nor via "Synaptic Package Manager".
What to do: Download JDK 7 binaries from the official Java site.
Problem 2: You are Debian/Ubuntu user and don’t see applicable .deb package.
What to do: Again, download JDK 7 binaries from the official Java site, install and configure it manually.
Step by step instructions to install and manual configure JDK 7 on the Ubuntu 10.04 LTS (the Lucid Lynx) desktop follow:
- For my X64 Ubuntu 10.04 LTS Desktop installation I downloaded Linux x64 – Compressed Binary file named jdk-7-linux-x64.tar.gz.
- Unpack it with command
gzip -d jdk-7-linux-x64.tar.gz
You will get jdk-7-linux-x64.tar file.
- Extract files from tar archive with command
tar -xvf jdk-7-linux-x64.tar
JDK 7 package is extracted into ./jdk1.7.0 directory.
- Move JDK 7 directory to place where it should be. Right, to the /usr/lib/jvm/jdk1.7.0 directory. Use this command for that
sudo mv ./jdk1.7.0/ /usr/lib/jvm/jdk1.7.0
- Execute this command
sudo update-alternatives --config java
to know under what number you will config you new Java installation. You will get output as:

$sudo update-alternatives –config java
There are 2 choices for the alternative java (providing /usr/bin/java).

Selection Path Priority Status
————————————————————
* 0 /usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 auto mode
1 /usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 manual mode
2 /usr/lib/jvm/java-6-sun/jre/bin/java 63 manual mode

Press enter to keep the current choice[*], or type selection number:

Remember the last number and press enter to exit this utility.
- Execute this command
sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.7.0/jre/bin/java 3
to add your new JDK 7 installation into alternatives list. I put 3 there as 2 was last number for my configuration. You should use your own number from the previous step increased by 1.
- Execute this command
sudo update-alternatives --config java.
You will see output similar one below:

$sudo update-alternatives –config java
There are 3 choices for the alternative java (providing /usr/bin/java).

Press enter to keep the current choice[*], or type selection number: 3
update-alternatives: using /usr/lib/jvm/jdk1.7.0/jre/bin/java to provide /usr/bin/java (java) in manual mode.

In case you have other answer from update-alternatives --config java command, e.g. ‘no alternatives for java’, try this command:

sudo update-alternatives –install /usr/bin/java java /usr/lib/jvm/jdk1.7.0/jre/bin/java 0

This will select needed java version in case you had not any previous java version installed before.

The job is done. Task is completed and work is finished. Just check version of your new JDK 7 installation typing this command java -version. You should see something like this:

~$ java -version
java version “1.7.0″
Java(TM) SE Runtime Environment (build 1.7.0-b147)
Java HotSpot(TM) 64-Bit Server VM (build 21.0-b17, mixed mode)

Please be aware that we changed alias just for one java binary only – “java” itself. There are a lot of others in Java package, e.g. “javac” compiler, etc. If you try to check javac version with “javac -version” command the most probably you will get that it still has 1.6 version, e.g. on my box:

~$ javac -version
javac 1.6.0_26

To update it, make the same as you did for java runtime environment:
sudo update-alternatives –config javac // Check the java compilers you have
sudo update-alternatives –install /usr/bin/javac javac /usr/lib/jvm/jdk1.7.0/bin/javac [-number]
Pay attention on the change of file location at the end of command. It is needed as there’s NO “javac” in the directory
“/usr/lib/jvm/jdk1.7.0/jre/bin/”
we used for JRE configuration in previous command.
Apply this technique for other Java binaries you use.

Thanks to Nikolavp’s blog for the hints about manual JDK 7 installation and configuration.

ip proxy knowledge

Tue, 14 Feb 2012 00:29:00 +0800

How do I hide my IP address?

The most common method to hide your IP address is to use a proxy server in one form or another. A proxy server is a computer that offers a computer network service to allow clients to make indirect network connections to other network services. A client connects to the proxy server and then requests a connection, file, or other resource available on a different server. The proxy provides the resource either by connecting to the specified server or by serving it from a cache. In some cases, the proxy may alter the client's request or the server's response for various purposes.

There are several implementations of proxy servers that you can use to hide your IP address (in an attempt to remain anonymous on the internet):

Website Based Proxy Servers

A Website based proxy server is a website that provides a form for you to enter the URL of a website that you wish to anonymously visit. When you submit the form the website proxy server makes a request for the page that you want to visit. The machine usually does not identify itself as a proxy server and does not pass along your IP address in the request for the page. The features of these sites vary (ad blocking, javascript blocking, etc) as does their price. Some are free and some charge. Examples of website proxy services are:

Proxify.com

Browser Configured Proxy Servers

There are also stand alone proxy servers that allow for you to configure your browser to route your browser traffic through that machine, which then makes a request for a page on your behalf, and then sends you the results. These are usually used at no cost to the user. Since they are accessible to the public these are often quite slow. Please see instructions for using a proxy server.

There are a variety of types of these proxy servers:

Transparent Proxy
This type of proxy server identifies itself as a proxy server and also makes the original IP address available through the http headers. These are generally used for their ability to cache websites and do not effectively provide any anonymity to those who use them. However, the use of a transparent proxy will get you around simple IP bans. They are transparent in the terms that your IP address is exposed, not transparent in the terms that you do not know that you are using it (your system is not specifically configured to use it.) This type of proxy server does not hide your IP address.
Anonymous Proxy
This type of proxy server identifies itself as a proxy server, but does not make the original IP address available. This type of proxy server is detectable, but provides reasonable anonymity for most users. This type of proxy server will hide your IP address.
Distorting Proxy
This type of proxy server identifies itself as a proxy server, but make an incorrect original IP address available through the http headers. This type of proxy server will hide your IP address.
High Anonymity Proxy
This type of proxy server does not identify itself as a proxy server and does not make available the original IP address. This type of proxy server will hide your IP address.

Installed Software Proxy Servers

There are a variety of companies and software packages available at either a onetime cost or at an annual subscription. These are usually faster and more reliable than the above proxy servers. Some of these services would include:

VPN Services

A virtual private network (VPN) protects your data and identity over public networks, like the Internet and wireless hotspots. Various protocols are used to create an encrypted tunnel that transports data securely. While a firewall may protect the data on your computer, a VPN will protect your data on the Internet. The goal of a VPN is to implement the same level of security provided by private networks at substantially lower costs. VPN services provide different gateway cities where the IP address assigned to your computer is located. This allows users to access websites only available to users from a certain country. This application is particularly important for travelers who need to access websites from their home country and for people living in regions rife with censorship, like China and Iran.

经分析，此源就是原来的cn99源，ping ubuntu.cn99.com的结果如下图：

我把163源放在以前常用的dormforce源之前，然后sudo apt-get update了一次。
下面是执行sudo apt-get dist-upgrade时候的截图：

从图可以看出来，和以前的cn99源一样，现在的163源仍然缺少部分软件包，有待完善：）

纳闷老是弹这东东出来，虽然。。。貌似不影响什么，可是看着不爽

好吧，Google到launchpad，有人提交bug，在讨论里有人说

装下那个engines就好了，就那么一行。。。

sudo apt-get install gtk2-engines-pixbuf

（在ubuntu 11.10下没发现有gtk3的。。不过装了这一样再没提示了）
