To import the Mininet virtual machine, use the VirtualBox menu command: File → Import Appliance Start the VirtualBox manager application on your host system. Next, create a version of the Mininet virtual machine that will run in VirtualBox by importing the Mininet virtual machine into the VirtualBox program
Import the virtual machine into VirtualBox The folder will contain the following files: mininet-vm-x86_64.vmdk

To decompress the archive, double-click on the mininet-2.1. file to automatically launch the archive application or use the following command in the terminal window: $ tar -xvf mininet-2.1. This file is a compressed ZIP archive containing two files so, after downloading it, decompress it and save the files to my hard drive. I chose the latest version available, which was mininet-2.1.

XQUARTZ SERVER CANNOT CONNECT TO DISPLAY INSTALL
On a computer running Windows, you need to download and install the required SSH and X-server software (I recommend PuTTY and XMing). On the Linux desktop distributions, the SSH and X-server software are already available. See the Apple Support web sit for more details at. You must install the XQuartz X server from.
XQUARTZ SERVER CANNOT CONNECT TO DISPLAY MAC OS X
The Mac OS X operating system comes with SSH software but does not come with an X server already installed. I set up the Mininet virtual machine on my Apple iMac computer. For my own reference, and to help anyone else who will install Mininet, I list the procedure I followed in the post, below. While I was following the procedure described in these notes, I found a few points where some more information would have been helpful.

The Mininet web site provides detailed setup notes, describing how to download and use the Mininet virtual machine. It is based on the Ubuntu Linux Server operating system and comes with all the software and tools required to support Mininet already installed. 7.The easiest way to get started using the Mininet network simulator is to use the Mininet virtual machine. This method is much more secure than the xhost one. The xauth method we can also use for running X clients on a remote host. If it is missing, the file will be created automatically. abf87ea2c8a4ed7f41ce8e7b99047870Īfter finishing, we remove the key: lion~> xauth rem $DISPLAY Xauth: file /home/lion/.Xauthority does not existĪuthorization required, but no authorization protocol specifiedįurthermore, we export the secret key xclock can run: lion~> xauth add $DISPLAY. In addition, we note xauth output xclock can’t run. Then, we switch to the lion and set up DISPLAY (or use the -E key in sudo, as in the example above) : lion:~> export DISPLAY=:0 We start by getting our DISPLAY and the secret key with the xauth command: panter~> set | grep DISPLAY Having logged to tiger, we set up DISPLAY to output on our local machine, jaguar in our case: $~ export DISPLAY=jaguar:0.0Īfter finishing and logging off, we remove the host from the list:
Its use, however, is dangerous because clients can connect to your DISPLAY from any host, making a security hole. Supposing, we’re sitting near the host jaguar and want to connect and run X client on the remote host tiger, but output its result locally, on jaguar.īefore establishing a connection to the remote host tiger, we need to add it to the list of allowed ones with the xhost command, xhost +our_remote_host: $~ xhost +tiger If X server accepts TCP connections, we can use the xhost method. Trusted connections may be suitable for running applications smoothly but undoubtedly nasty for security. They can do keylogging, screenshots, and input into other programs’ windows it can use all X server extensions like accelerated graphics.

Trusted ones have full access to the entire DISPLAY. These two keys are for untrusted and trusted connections correspondingly. Instead of -X, we may use the -Y key, but it makes sense only if this sshd is suitably configured. Last login: Wed Dec 1 14:32: from home on pts/4 The typical DISPLAY value is localhost:10.0: :~> ssh -X That’s all, of course, if the ssh daemon sshd runs on the remote end and its configuration file, sshd_config, includes the line X11Forwarding yes. So, we’ll ssh -X our_remote_host and, after logging in, we start X11 applications. The best way to start a remote X client is to use ssh with the so-called X Forwardingto direct the X protocol packets over the same connection we use for the commands.
