Please consider DDoS Protected VPS for your needs.
What is a GRE tunnel?
Much like a proxy, a GRE tunnel allows you to pass traffic from your VPS including DDoS filtering to another remote destination.
GRE tunnels allow all traffic through, not just HTTP. With a GRE tunnel you can serve, and deliver any type of content from any type of server (audio, FTP, SSH, SCP, video, etc.).
What can your use a GRE tunnel for?
GRE tunneling is very handy when you want to use our DDoS filtering services to protect services that are too large to host with us (I.e. game servers, Java applications, large database driven applications, etc.).
VNC or Virtual Network Computing is a platform-independent protocol that enables users to connect to a remote computer system and use its resources from a Graphical User Interface (GUI).
It’s like remote controlling an application: the client computer’s keystrokes or mouse clicks are transmitted over the network to the remote computer. VNC also allows clipboard sharing between both computers. If you come from a Microsoft Windows server background, VNC is much like the Remote Desktop Service, except it’s also available for OS X, Linux, and other operating systems.
Like everything else in the networking world, VNC is based on the client server model: VNC server runs on a remote computer — your Droplet — which serves incoming client requests.
In this tutorial we will learn how to install and configure a VNC server on CentOS 7. We will install the TigerVNC server which is freely available from the TigerVNC GitHub repository.
This tutorial will show you how to install Java on CentOS 7 (also 5, 6, 6.5), Fedora 20, and RHEL. Java is a popular software platform that allows you to run Java applications and applets.
Feel free to skip to your desired section using the Contents button on the sidebar!
Before you begin this guide, you should have a regular, non-root user with sudo privileges configured on both of your servers–this is the user that you should log in to your servers as. You can learn how to configure a regular user account by following steps 1-4 in our initial server setup guide for Ubuntu 14.04.
There are three different editions of the Java Platform: Standard Edition (SE), Enterprise Edition (EE), and Micro Edition (ME). This tutorial is focused on Java SE (Java Platform, Standard Edition).
There are two different Java SE packages that can be installed: the Java Runtime Environment (JRE) and the Java Development Kit (JDK). JRE is an implementation of the Java Virtual Machine (JVM), which allows you to run compiled Java applications and applets. JDK includes JRE and other software that is required for writing, developing, and compiling Java applications and applets.
There are also two different implementations of Java: OpenJDK and Oracle Java. Both implementations are based largely on the same code but OpenJDK, the reference implementation of Java, is fully open source while Oracle Java contains some proprietary code. Most Java applications will work fine with either but you should use whichever implementation your software calls for.
You may install various versions and releases of Java on a single system, but most people only need one installation. With that in mind, try to only install the version of Java that you need to run or develop your application(s).
This section will show you how to install the prebuilt OpenJDK 7 JRE and JDK packages using the yum package manager, which is similar to apt-get for Ubuntu/Debian. OpenJDK 7 is the latest version of OpenJDK.
At the confirmation prompt, enter y then RETURN to continue with the installation.
Congratulations! You have installed OpenJDK 7 JRE.
Congratulations! You have installed OpenJDK 7 JDK.
This section will show you how to install the prebuilt OpenJDK 6 JRE and JDK packages using the yum package manager.
Congratulations! You have installed OpenJDK 6 JRE.
Congratulations! You have installed OpenJDK 6 JDK.
This section of the guide will show you how to install Oracle Java 8 update 60 JRE and JDK (64-bit), the latest release of these packages at the time of this writing.
Note: You must accept the Oracle Binary Code License Agreement for Java SE, which is one of the included steps, before installing Oracle Java.
Note: If you would like to install a different release of Oracle Java 8 JRE, go to the Oracle Java 8 JRE Downloads Page, accept the license agreement, and copy the download link of the appropriate Linux .rpm package. Substitute the copied download link in place of the highlighted part of the wget command.
Now Java should be installed at /usr/java/jdk1.8.0_60/jre/bin/java, and linked from /usr/bin/java.
Congratulations! You have installed Oracle Java 8 JRE.
Note: If you would like to install a different release of Oracle Java 8 JDK, go to the Oracle Java 8 JDK Downloads Page, accept the license agreement, and copy the download link of the appropriate Linux .rpm package. Substitute the copied download link in place of the highlighted part of the wget command.
Congratulations! You have installed Oracle Java 8 JDK.
This section of the guide will show you how to install Oracle Java 7 update 79 JRE and JDK (64-bit).
Note: If you would like to install a different release of Oracle Java 7 JRE, go to the Oracle Java 7 JRE Downloads Page, accept the license agreement, and copy the download link of the appropriate Linux .rpm package. Substitute the copied download link in place of the highlighted part of the wget command.
Now Java should be installed at /usr/java/jdk1.7.0_79/jre/bin/java, and linked from /usr/bin/java.
Congratulations! You have installed Oracle Java 7 JRE.
Note: If you would like to install a different release of Oracle Java 7 JDK, go to the Oracle Java 7 JDK Downloads Page, accept the license agreement, and copy the download link of the appropriate Linux .rpm package. Substitute the copied download link in place of the highlighted part of the wget command.
Congratulations! You have installed Oracle Java 7 JDK.
If you installed multiple versions of Java, you may want to set one as your default (i.e. the one that will run when a user runs the java command). Additionally, some applications require certain environment variables to be set to locate which installation of Java to use. This section will show you how to do this.
The alternatives command, which manages default commands through symbolic links, can be used to select the default Java command.
Simply enter the a selection number to choose which java executable should be used by default.
Many Java applications use the JAVA_HOME or JRE_HOME environment variables to determine which java executable to use.
Congratulations, you are now set to run and/or develop your Java applications!
This guide explains how to configure static IP address, dns configuration and hostname on debian based Linux distributions on the shell. It will be same on server & desktop.
With the introduction of the Apache2 packages in Debian it is much simpler to create and use a secure SSL protected webserver than in the old days with Apache 1.3, here we’ll show how it is done.
