OpenSSH Server

OpenSSH Server

Introduction

This section of the Ubuntu Server Guide introduces a powerful collection of tools for the remote control of networked computers and transfer of data between networked computers, called OpenSSH. You will also learn about some of the configuration settings possible with the OpenSSH server application and how to change them on your Ubuntu system.

OpenSSH is a freely available version of the Secure Shell (SSH) protocol family of tools for remotely controlling a computer or transferring files between computers. Traditional tools used to accomplish these functions, such as telnet or rcp, are insecure and transmit the user’s password in cleartext when used. OpenSSH provides a server daemon and client tools to facilitate secure, encrypted remote control and file transfer operations, effectively replacing the legacy tools.

The OpenSSH server component, sshd, listens continuously for client connections from any of the client tools. When a connection request occurs, sshd sets up the correct connection depending on the type of client tool connecting. For example, if the remote computer is connecting with the ssh client application, the OpenSSH server sets up a remote control session after authentication. If a remote user connects to an OpenSSH server with scp, the OpenSSH server daemon initiates a secure copy of files between the server and client after authentication. OpenSSH can use many authentication methods, including plain password, public key, and Kerberos tickets.

Installation

Installation of the OpenSSH client and server applications is simple. To install the OpenSSH client applications on your Ubuntu system, use this command at a terminal prompt:

sudo apt-get install openssh-client

To install the OpenSSH server application, and related support files, use this command at a terminal prompt:

sudo apt-get install openssh-server

The openssh-server package can also be selected to install during the Server Edition installation process.

Taste the Rainbow: The Mouthwatering Colors of ‘Big Hero 6’ «

Coloring in animated movies has reached a place beyond conventional realness. It’s in a hyper-sensory realm. Merely watching Big Hero 6 feels inadequate. It does something synesthetic. It’s true that I didn’t see it in 3-D, but I’m not sure getting closer to the images would have kept me from trying to leap through the screen. This movie is so energetically fulgent and steroidally sweet that watching it is basically like losing your mind in the drug-store candy aisle. You want to lick the light and bite fake plastic and metal. (This must be what it’s like for kids to stand in front of a Jeff Koons.) I don’t know whether scientists have found a correlation between films that look like this and children’s addiction to them. But The Lego Movie looks like a galaxy of hard candy and happens to have grossed a zillion dollars. There are movies that treat you like a toddler and movies that reduce you to one. Big Hero 6 is the latter. You want to shove the whole thing in your mouth.

A Brief History of Murder Islands: How ‘The Hunger Games: Mockingjay’ Built a Dystopia From Scraps «

We need more symbolism like this in our drive against corruption in government.

On Tuesday, in the city of Khon Kaen, Thailand, five college students were arrested for making the three-fingered District 12 salute during an appearance by Thai prime minister Prayuth Chan-ocha, who seized control of the country in a military coup this past May. Anti-coup activists have adopted the gesture (now illegal in Thailand) as a silent symbol of defiance, proving once again that you don’t really know what a film is about until an audience tells you. On Thursday, three more students were detained for throwing up the District 12 sign outside a shopping-mall multiplex in Bangkok.

The genius of the Filipino poor | Inquirer Opinion

Graham’s book (now being translated into French) is not heavily laden with statistics and high-brow jargon about wealth and poverty, development and underdevelopment. One meets in the pages of his book real persons with names, addresses and life stories—stunning, sad, amazing, heartbreaking—to share. In their company he saw, as if for the first time, his own life in a different context.

One might ask if Graham is not perhaps romanticizing the poor, they who have lived lives mired in vice, violence, criminality and hate. Where is the “genius” he is talking about?

Graham quotes Emong of Bagong Silang: “Even if you’re a drug addict or criminal like I was, you can change in a minute if you realize that you can help others. We need to give people a chance to help others and do good. As soon as you realize that others care about you, you gradually begin to care about them, too. This is the basis for change.”

Graham reflects: “Genius, I have discovered, lies not just in individual brilliance in some area of human activity, but in a supremely positive, humane attitude to life, to its ups and downs, to its unfairness and opportunities, and above all, to other people—family, neighbor, stranger. In this respect I have glimpsed genius in the impoverished… And in the process I have been taught, not how to pass an exam or appear intelligent, but simply how to live a more authentic human life.”

Is P-Noy being soft on Binay? | Inquirer Opinion

The investigation of the Senate blue ribbon subcommittee should not be stopped until we get the whole story. Not because, as Palace spokesperson Edwin Lacierda seems to imply, the Senate cannot trust the Office of the Ombudsman and the NBI to do the job. And not because, as Sen. Nancy Binay insists, the court is the only place where the issue can be resolved.

But because those entities are, from experience, going to take their own sweet time about it. And time is what the Filipino people do not have. They are going to the polls in 2016, and the information that the Senate investigation provides them about the presidential candidates (Binay is the only declared candidate, but Sen. Alan Peter Cayetano and Trillanes seem to be hopefuls—their behavior can also be judged) will be invaluable.

Only Ayalas didn’t give Binay condos–Mercado | Inquirer News

Testifying at the resumption of the Senate blue ribbon subcommittee inquiry into supposed Makati irregularities, Mercado alleged that Binay used dummies to hide his ownership of these condominium units—a charge the Vice President’s camp denied.

As examples (mga halimbawa), Mercado cited six buildings where Binay allegedly had units and presented a notarized affidavit from Ariel Olivar, an engineer who admitted he was used as a front for Binay’s unit at The Peak condominium.

Mercado also alleged that among the other buildings where Binay owned a unit were the Le Triomphe condominium; the Makati Sunrise Tower, now the Berjaya Hotel; Perla Compania de Seguros Mansion Condotel; Prince Plaza II Condotel; and Avignon Tower.

Mabini in America | Inquirer Opinion

The day Mabini was buried saw an unprecedented outpouring of support and sympathy [I have written on this before]. Thousands of people joined the funeral procession. A visiting American woman, whose name I [still] have not yet been able to determine, wrote a vivid account for a Boston newspaper [which included this extraordinary passage]: “It seemed as though the whole city of Manila had gathered, and I could not help noticing the large proportion of strong and finely intelligent faces, especially among Mabini’s more intimate friends. Most noticeable, also, and with a certain suggestiveness for the futrue sic, was the extraordinary number of young men, many of them evidently students, keen, thoughtful and intelligent looking.” [She saw Mabini in his mourners.]Mabini was never in America, of course. At the turn of the 20th century, Guam [his place of exile] was a new possession of the United States, American soil-in-the-making. So the man whom LeRoy called the “chief irreconcilable,” whom Gen. Elwell Otis labelled the “masterful spirit” behind Philippine resistance to American occupation, was only present in the United States in the sense that he represented a new idea—an intellectual at the head of a revolution, an ideologue.In Mabini’s America, he was the un-Aguinaldo.
