    If you have a Gmail account, you can configure your MTA to relay outgoing mail through Gmail. This gives you the benefit of Gmail's reliability and robust infrastructure, and provides you with a simple means of sending email from the command line.

  • How to Block Email from certain TLDs (Top Level Domains) in ISPConfig

    Spam is an annoyance and there's a multitude of ways to counteract it. However spammers also get smarter and try to bypass filters and stuff. In addition, ICANN has lately approved a great mean gTLDs (generic Top Level Domains), like .biz, .info etc. Some of those gTLDs are, in my opinion, exclusive used by spammers. Lately, I have gotten a lot of spam from the .xyz gTLD. So the question was, how to block email coming from such domains using that gTLD.

  • An introduction to Linux activity/event trackers

    linux Author: Bill ToulasTags: , , , , , , Comments: 1

    Most modern GNU/Linux distributions use some kind of a software service that tracks the user activities and events. These events can be anything, from the opening of a document file, to the chat conversation. This isn't happening for the purpose to monitor the user and sell this usage data information to 3rd parties, but to help users enjoy a more user-friendly and unified experience across their applications. For example, if you want to quickly locate that document that you opened last weekend, chances are that you will easily and promptly find it after opening your file manager and going to the “Recent” folder.

    It is not an uncommon situation, for early adopters of newly introduced concepts and technologies, to be totally confused when these can fundamentally change the ways of developing and delivering services. Especially when everybody talks about something like Docker, and how awesome and game changing it is. This confusion happens when we try things early on and rushing straight to testing them without grasping the whole concept and background of this newly introduced technology.

    Codeweavers has released a new major version of Crossover, the popular Microsoft Windows compatibility layer which is now based on Wine 1.8. The software is commercial and it costs around $40, but there is also a two-week trial version which is fully functional and can be downloaded for free. For this quick guide, I will be using the latter to show how you can install, set up, and run Windows executables with Crossover 15.

    LibreOffice is one of the most important pieces of free software, allowing many of us to work, study, and share information. Although the software features many tools and capabilities, the spectrum of possible uses for each and everyone out there is so wide, that it is simply impossible to cover every special need with hotkeys and shortcuts. However, LibreOffice can be set to support user-created commands that can essentially help us increase our productivity.

  • How to convert packages between .deb and .rpm

    linux Author: Bill ToulasTags: , , , , , Comments: 2

    Unfortunately, and after years of development in every part of the free software that we enjoy, there are still two primary types of software package available in GNU/Linux systems. The one is the .deb type which is used by Debian and Debian-based distributions like Ubuntu, Mint, and Elementary, and the other is the .rpm type which is used by Fedora, openSUSE, Mageia, and CentOS. Fortunately, there's a workaround for this as we can try to transform the one type to the other.

  • Advanced Audio Control on Linux

    linux Author: Bill ToulasTags: , , , , , , Comments: 5

    Linux audio control is as messed up as the Linux audio system structure. The default and only option of setting the volume level may be enough for the majority of users out there, but it certainly isn't the best when you want to set specific audio levels, or define individual settings for different audio sources, etc. Here is a post on a selection of utilities that could help you get the sound you want on your Linux system.

  • How to use snapshots, clones and replication in ZFS on Linux

  • How to connect your Android device on Ubuntu Linux

    ubuntu Author: Bill ToulasTags: , , , , , Comments: 15

    Buying a media device that needs a special driver and/or connectivity suite to navigate and update its contents is a common case nowadays, and has been ever since manufacturers decided that it would be a good idea to just limit the access that users can have on the products that they bought. This may not be a huge problem to Windows and Mac OS users who can simply download the manufacturer's suite and use it to connect to their device, but Linux is often (if not always) left unsupported in that part. The first time I encountered this problem was with the first generation of iPods and Creative Zen players that refused to show any contents on the File Manager when connected via the USB port, and then came the newest generations of Android devices which do the same. In this quick guide, we will see how we can overcome this problem, and connect our media device on our Linux system.
