How to Block Email from certain TLDs (Top Level Domains) in ISPConfig
Author: Stephan Jau • Tags: centos, debian, email, linux, opensuse, suse, ubuntu • Comments: 5
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
Author: Bill Toulas • Tags: centos, debian, desktop, fedora, opensuse, suse, ubuntu • 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.

How to setup virtual containers with LXC and quota support on Debian 8
Author: Croydon • Tags: debian, linux, virtualization • Comments: 4
Quota support is an often requested feature in lxc. Linux filesystem quota is required when you want to give multiple users access to a container and want to control that one user is not using all the disk space. Quota is also required for web hosting servers, e.g. with ISPConfig 3, for the same reason: one website shall not be able to fill up the whole disk. This howto shows you, how you can use lxc with hard disk quota using qemu nbd with a qcow image file on Debian 8.

Thoughts on Monitoring file changes with Linux over the network
Author: stefbon • Tags: centos, debian, linux, networking, opensuse, shell, ubuntu • Comments: 1
Monitoring a directory for changes with Linux is possible through the well-known mechanism inotify. With inotify it's possible to set a watch on a directory, configure it to watch events on the contents, and you'll receive messages on a file descriptor when something happens. This works perfectly when the directory is on local storage, like a hard drive, SSD or a USB drive, But it is not sufficient when the directory is on a network filesystem when the storage is on another computer. Another user working in the same directory, connected via the same or another filesystem, can remove a file and the watch you've set on it will not get notified.

How to use Docker in a practical way (part 1 - Introduction)
Author: Bill Toulas • Tags: centos, debian, fedora, opensuse, suse, ubuntu, virtualization • Comments: 7
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.

How to install and configure vsftpd with TLS on Debian 8 (Jessie)
Author: Till Brehm • Tags: debian, ftp, security • Comments: 8
This article explains how to set up a TLS enabled vsftpd server on a Debian 8 server. FTP is a very insecure protocol by default because all passwords and all data are transferred in clear text. By using TLS, the whole communication can be encrypted, thus making FTP much more secure.

How to Encrypt your Data with EncFS on Debian 8 (Jessie)
Author: Till Brehm • Tags: debian, security • Comments: 4
EncFS provides an encrypted filesystem in user-space. It runs without any special permissions and uses the FUSE library and Linux kernel module to provide the filesystem interface. It is a pass-through filesystem, not an encrypted block device, which means it is created on top of an existing filesystem. This tutorial shows how you can use EncFS on Debian Jessie to encrypt your data.

How to use custom commands in LibreOffice
Author: Bill Toulas • Tags: centos, debian, desktop, linux, opensuse, suse, ubuntu • Comments: 2
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.
