How to protect Apache with Fail2ban

Apr 232013

Around 2 years ago I wrote an article about fail2ban.

Fail2ban is an intrusion prevention framework written in the Python programming language. It is able to run on POSIX systems that have an interface to a packet-control system or firewall installed locally (such as, iptables or TCP Wrapper).
Fail2ban’s main function is to block selected IP addresses that may belong to hosts that are trying to breach the system’s security. It determines the hosts to be blocked by monitoring log files (e.g. /var/log/pwdfail, /var/log/auth.log, etc.) and bans any host IP that makes too many login attempts or performs any other unwanted action within a time frame defined by the administrator.

This is the translation of an article by Roberto Ferramosca, published in Italian on lffl.org, a great Italian Blog about Linux and Open source.

One of the main features of Linux is to provide a complete and functional operating system that can completely work also on dated PC where Windows XP has now become too old and the new Windows 7 requires too many resources.
Linux can revive pc set aside because the hardware is no longer supported by Microsoft operating system and so providing a fast, complete and secure environment.

I’ve received this news from proxmox press office, I really like their effort and their product and so I’ve decided to post their press release that celebrate their 5th anniversary:

Proxmox Virtual Environment, the open-source server vitualization platform, is celebrating its 5th anniversary today. When Vienna Proxmox Server Solutions launched the first version of Proxmox VE V0.9 on April 15, 2008 – exactly five years ago – the software was the first open-source solution providing an integrated GUI for KVM and container-virtualization. With this approach IT administrators can manage their KVM and OpenVZ containers easily via a web-based interface. In the last five years Proxmox VE has become the mainstream open-source business alternative to commercial virtualization platforms like VMware vSphere, Microsoft Hyper-V, Oracle VM or Citrix XenServer.

According to Proxmox, today 40.000 hosts in more than 140 countries worldwide use Proxmox VE – with a continued growth of its user base. The GUI is available in more than 16 languages and the support forum states over 20,000 members. Proxmox Server Solutions offers several levels of support subscription plans for business-use, ranging between 120 and 800 Euros per year.

Sometimes can be useful to have a small program that you can run from the command line and able to do a screenshot of your desktop or just a portion of it, for this task the perfect software is: scrot

Scrot (SCReenshOT) is a screen capture utility using the imlib2 library to aquire and save images. scrot has a few really interesting options, detailed below. The basic usage is to specify a [file] as the filename to save the screenshot to and scrot will take a screenshot of the whole desktop.
The latest release (0.8) has almost 10 years, still this small program can be useful for his ability to be run completely from the command line and so you could use it to concatenate other commands or just because it’s really lightweight and easy to use.
