SSH Tutorial for Linux - Support Documentation
This document covers the SSH client on the Linux Operating System and other OSes that use OpenSSH. If you use Windows, please read the document SSH Tutorial for Windows If you use Mac OS X or other Unix based system, you should already have OpenSSH installed and can use this document as a reference. This article is one of the top tutorials covering SSH on the Internet. It was originally written back in 1999 and was completely revised in 2006 to include new and more accurate information. As of October, 2008, it has been read by over 473,600 people and consistently appears at the top of Google's search results for SSH Tutorial and Linux SSH. What Is SSH? There are a couple of ways that you can access a shell (command line) remotely on most Linux/Unix systems. An unencrypted telnet session SSH, which is an acronym for Secure SHell, was designed and created to provide the best security when accessing another computer remotely. An encrypted ssh session Getting Started OpenSSH can be obtained from

WPILibJ: edu.wpi.first.wpilibj.image.NIVision Class Reference Class for interfacing with the NIVision libraries. More... Class for interfacing with the NIVision libraries. Author OpenSSH/Client Configuration Files Client configuration files can be per user or system wide, with the former taking precedence over the latter and run-time arguments in the shell overriding both. In these configuration files, one parameter per line is allowed with the parameter name followed by its value or values. Empty lines and lines starting with the hash (#) are ignored. An equal sign (=) can be used instead of whitespace between the parameter name and the values. Values are case-sensitive, but parameter names are not.

FRC 2168 OpenCV library for the roboRIO and BeagleBone processors : WPILib OpenCV is the premier open source vision library and can be found in many commercial and research robots. From the OpenCV web site: “OpenCV is released under a BSD license and hence it’s free for both academic and commercial use. It has C++, C, Python and Java interfaces and supports Windows, Linux, Mac OS, iOS and Android. OpenCV was designed for computational efficiency and with a strong focus on real-time applications. Written in optimized C/C++, the library can take advantage of multi-core processing.

removing outdated ssh fingerprints from known_hosts with sed or … ssh-keygen At least from the last issue in Debian-based systems including Ubuntu you might know the pain of getting the message from you ssh client that the server host key has changed as ssh stores the fingerprint of ssh daemons it connects to. Actually this is a neat feature because it helps you detecting man in the middle attacks, dns issues and other things you probably should notice. Until recently I opened the file .ssh/known_hosts in vim, deleted the entry, saved the file and started over again. I randomly checked “man ssh” which gives you a lot of hints about the usage of known_hosts but I just did not find information about how to delete an old fingerprint or even overwrite it. I imagined something like “ssh –update-fingerpring hostname” with an interactive yes/no question you cannot skip.

Configuring an Axis Camera Three different Axis camera models are supported by the FRC software, the Axis 206, Axis M1011 and Axis M1013. This document provides instructions on how to configure one of these cameras for FRC use. To follow the instructions in this document, you must have installed the NI 2015 FRC Update Suite and Configured your radio Editing known_hosts in ubuntu - Ars Technica OpenForum I foolishly asked this question in the ubuntu forums, instead of going first to the hive and got little useful in response. What say arsians on this topic? I recently re-installed ssh on one of my ubunbtu boxes & found that I could not ssh to it any more from the other and got a long error regarding RSA keys changing an possible man in the middle attacks which ended with this: Add correct host key in /root/.ssh/known_hosts to get rid of this message. I searched for the message on-line and found suggestions regarding removing the offending line so that ssh would accept the new host key.

2015 FIRST® Robotics Competition RoboRealm is a software application that provides you the ability to rapidly process images from the Kinect and/or Axis IP camera in order to visually detect field elements. You can use RoboRealm to track positional markers, follow lines, track balls, and augment camera images with additional visual graphics. RoboRealm is an ideal vision platform for the Hybrid Autonomous period and human controlled parts of the competition (i.e. Augmented Driving). In the spirit of inspiring young people to be science and technology leaders, RoboRealm is actively supporting the 2015 FIRST® Robotics Competition.

How To Fix Offending key in ~/.ssh/known_hosts file by Ramesh Natarajan on April 30, 2010 As we discussed earlier in our basic ssh client commands article, when you do ssh to a machine for the 1st time (or whenever there is a key change in the remote machine), you will be prompted to say ‘yes’ for authenticity of host. This feature is controlled using StrictHostKeyChecking ssh parameter. TeamForge : Project Home The WPILib Project contains resources for programming an FRC robot in C++ or Java (the C++ and Java versions of the WPILib update for 2015 FRC Season). This FIRST Forge project includes a bug tracker, documentation, source code, WPILib releases, and a wiki. To get started, please see the Documentation on this site Install tshark On CentOS Linux Using The Yum Package Manager - Question Defense I use tshark sometimes to strip down packet captures based on specific variables and needed to install tshark on a CentOS Linux server I recently built for various development tasks. The problem is that when attempting to install tshark using yum it returned an error because there was no package named tshark available in any of the yum repositories I had configured.

Command Based Structure · BadRobots1014/BadRobot2013 Wiki Explanation of Command-based Robot FRC has done a remarkable job providing the tools to create complex robot programs. However, they have not been so thorough in providing documentation as to how to first pick up these tools and get to work. Through hours of browsing forums of other team’s and contributing to writing my own team’s (Team 1014) Java Command-based robot code, I have developed a much better understanding of the structure and the connections between classes that FRC expects programmers to use. This document explores Command-based Java robot programs, the new paradigm supported as of 2012. Disclaimer: Although this tutorial is not highly technical, a basic understanding of Java (classes, methods, variables) is assumed. Install Htop - Linux Process Monitoring for RHEL, CentOS & Fedora In our earlier series of system monitoring article where we explained about Iotop (Monitor Linux Disk I/O) tool, now today we are so exciting to install another system process monitoring tool called Htop on our CentOS 6.3 box to see how it works. It should work on RedHat/Fedora as well. I had heard that htop is replacement of Unix/Linux Top command.
