Secure Shell is a program to log into another computer over a network, to execute commands in a remote machine, and to move files from one machine to another. It provides strong authentication and secure communications over unsecure channels. It is intended as a replacement for telnet, rlogin, rsh, and rcp. For SSH2, there is a replacement for FTP: sftp.This might be useful if you are trying to connect everytime to your server remotely.

A Trust relationship can be established for users on multiple servers running OpenSSH to allow a password free ssh session. This is sometime important when you want to run scripts or commands remotely.

There are times when you'd like to conduct complex conditional actions within a CFEngine setup. Whilst it is possible to use built in classes, or dynamic tests for the existence of files, directories, or other things using an external plugin module gives you a lot of additional flexability.

CFEngine allows you to conduct different actions by "groups" and by "classses". Groups are generally defined in a static fashion such as this:

Sun Microsystems is contributing Project Looking Glass, based on Java™ technology, to the open source community.

Project Looking Glass is an exploratory project to bring innovative 3D features to the desktop environment. The desktop interface will offer an intuitive, new 3D environment to interact with desktop applications featuring window transparency, rotation, zoom, multiple desktop workspaces, and miniaturization. Project Looking Glass offers a platform to realize a far richer and more entertaining user experience for existing and new applications in 2D or 3D. The technology enables developers to build highly visual 3D desktops and applications that will run on Linux systems such as Sun’s Java Desktop System. The Solaris™ environment will be supported in the near future.

We are not entirely certain why the swap partition was not added to the /etc/fstab, however, we noticed when running top that our swap space was showing up as 0k available, 0k used. This was a recent problem found on one of the web servers hosting http://forums.techguy.org. The web server had a fresh install of Fedora Core 4 but didn't appear to have any swap space. Following are the steps taken to correct the problem.

First we needed to determine if the swap partition existed. To do this we issued the following command as root:

A thread on ubuntuforms.org , called "HOWTO: Set up VNC server with resumable sessions", described how to do something that I have been trying to do with Xubuntu for a while. Ubuntu remote desktop access is easier due to the inclusion of the vino-server. The thread went on for a number of pages and this post attempts to capture all of the bits relevant to getting this working on Xubuntu. This was done on a Fiesty Fawn installation, but should work on Edgy.

The objective is

* to allow remote access to a Xubuntu desktop and,
* in this case, this will be in the form of a resumable session, and
* to not use any GNOME libraries.

Xubuntu Remote Desktop with VNC4Server


One of the first things I setup long ago when I first switched to Ubuntu was a streaming media server. I decided early on to just dive in and see what I could (and couldn’t) do. I had an extra machine lying around so I thought I would give it a try and setup gnump3d.

At this point (years later) I have a dedicated media server running on my fiber connection to offer me access to my music collection from any available internet connection! It’s beautiful! All you’ll need to set this up is an Ubuntu machine (desktop, server, laptop–anything you can store media on) and an internet connection. It can also simply be used on a local network to share music with other users or between computers in your network or home.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
