  • GoAccess – Visual Web Log Analyzer – GoAccess is an open source real-time web log analyzer and interactive viewer that runs in a terminal in *nix systems. It provides fast and valuable HTTP statistics for system administrators that require a visual server report on the fly.
  • bonasia.info: apt-get – Una guida veloce ad apt-get, apt-cache, etc
  • FastVPSEestiOu/fastnetmon – FastNetMon – high performance DoS/DDoS and netflowk load analyzer builded on top of multiple packet capture engines (netmap, PF_RING, sFLOW, Netflow, PCAP). What we do? We can detect hosts in our own network with big amount of packets per second/bytes per second or flow per second incoming or outgoing from certain host. And we can call external script which can send notify, switch off server or blackhole this client. [ via https://delicious.com/farmando ]

  • check_jvm – Nagios Exchange – JvmInspector is standalone tool + Nagios wrapper plugin (check_jvm) that dumps various properties from locally running JVMs. This information includes: * Heap & non-heap memory * Running threads * Loaded classes * Running java version, paths & arguments * On App servers only: Container server name & total active sessions (tested & supported app servers are tomcat5+ and jboss4+) JvmInspector doesn't need local or remote JMX network socket. It directly attaches to JVM's PerfData, so it MUST be started with the same USERid as the target JVM!
  • Raspberry Pi VPN Gateway – Netflix finally arrived in Germany, but guess what? It's library is heavily limited in comparision to the US one and if you like TV series as much as I do, you don't want to wait until they eventually release it year(s) later for us german users. Maybe you've heard recently of Anonabox — a small device with two ethernet ports that you can plug in front of your router and everything behind the device is routed through Tor (side note: turned out to be a scam and got pulled from Kickstarter in the end). However, it made me come up with an idea: Instead of having a Tor-box, I want a VPN-box that is connected to my PrivateInternetAccess VPN. If I'm in need of a VPN connection I just switch the WiFi network and I'm good to go. This way I can easily watch US content from Netflix as well as unblock location restricted content like YouTube, even with my iPhone or Xbox[…]
  • My Tmux Setup on unwiredcouch.com – I've been using tmux as my main terminal multiplexer for about 3 years now and have refined my configuration over time to fit my daily workflow. Which is usually a mix of writing code, chef recipes, remote login into different servers and various shell tasks. This is a flexible setup that doesn't concentrate too much on doing a specific thing or replacing an IDE inside of tmux.

  • sebsauvage/rss-bridge – The RSS feed for websites missing it
  • debsecan – The debsecan program evaluates the security status of a host running the Debian operation system. It reports missing security updates and known vulnerabilities in the programs which are installed on the host. debsecan accesses the dpkg database and obtains a list of installed packages and their versions. This list is then evaluated against a feed of vulnerability information which ultimately comes from a database maintained by Debian's Testing Security Team . Various output formats are supported, including incremental reporting via email. Beginning with version 0.2, debsecan includes a script called debsecan-create-cron, which allows you to create a cron job which periodically sends you mail (once per day) when the security status of the system changes.
  • Barriers, Caches, Filesystems | monolight – With the recent proliferation of ext4 as the new “default” Linux filesystem there’s been much talk of write barrier support. The flurry of post-2.6.18 barrier related development in most storage subsystems has left some novice users and administrators perplexed. I hope I can clear it up a bit with this primer/refresher.
  • SMTP, testing via Telnet – FreeBSDwiki – When troubleshooting problems with SMTP service – your own, or others – it is frequently very helpful to be able to "speak" to the SMTP server directly, rather than going through a mail client which won't necessarily tell you exactly what the SMTP server is saying. You can easily do this with the telnet client. Note that many ISPs do not allow outbound connections on port 25 to any SMTP server but their own – if you get timeouts when trying to connect to port 25, you should try port 587, which is the standard ESMTP port. (Port 587 connections normally require SMTP AUTH, which is covered below.)

  • AppArmor – Ubuntu Wiki – AppArmor is a Mandatory Access Control (MAC) system which is a kernel (LSM) enhancement to confine programs to a limited set of resources. AppArmor's security model is to bind access control attributes to programs rather than to users. AppArmor confinement is provided via profiles loaded into the kernel, typically on boot. AppArmor profiles can be in one of two modes: enforcement and complain. Profiles loaded in enforcement mode will result in enforcement of the policy defined in the profile as well as reporting policy violation attempts (either via syslog or auditd). Profiles in complain mode will not enforce policy but instead report policy violation attempts.
  • AppArmor – Documentation –
  • SmoothSec – Smooth-Sec is a fully-ready IDS/IPS (Intrusion Detection/Prevention System) Linux distribution based on Debian 7 (wheezy), available for 32 and 64 bit architecture. The distribution includes the latest version of Snorby, Snort, Suricata, PulledPork and Pigsty. An easy setup process allows to deploy a complete IDS/IPS System within minutes, even for security beginners with minimal Linux experience. [ via https://delicious.com/farmando ]

  • How to interpret the status of dpkg (–list)? | Programming in Linux – dpkg (debian package manager) is the package manager for Ubuntu (debian based distributions). dpkg can be used to install packages in Ubuntu. With dpkg, you can see the status of various packages like: the packages are currently installed the packages are removed the configuration files are present marked for removal Let’s explore the output of dpkg –list.
  • Jugnu Life :-): How to install Tomcat in Linux (Ubuntu) – To install Tomcat we need Java to be installed in the system. If you want to know how to install Java on Linux you can refer this earlier post on the same. We can install Java either using packages (apt , yum) or manually. This post explains how to do it manually. The main advantage of doing it manually is that all the tomcat files are in one location. The automated installation will spread the setup files across various locations. It places the Tomcat configuration files at various non standard places.

  • Magento caching, APC, eAccelerator Memcached, files, sqlite, Vanish, what’s the … happen? | Alex Paradise – Magento is slow! It’s how start most of the article about Magento cache optimization. Yes, Magento is slow and this because of the way the code is written, extreme object oriented. Stackoverflow say “It is written in an Enterprise Java idiom” and there are right. Anyway, we can’t change anything about it and in one side that let us lot of flexibility.
    So, Magento IS SLOW! And what’s can we do? There is many thing to do, many, many. But the most important one is to work around the cache. I am searching for a cache solution and found so much different stuff like APC, eAccelerator, memcached, tmpfs, varnich, lighthttpd, nginx and so on… I will try to explain the different possibilities if found while my research and finished by the one I will implement[…]

  • Debian Clusters – This site is a series of step-by-step tutorials for anyone interested in building a Debian cluster. It is geared particularly towards those interested in a Debian cluster for education or research purposes. This site is being written alongside the construction of a real Debian cluster at my institute, starting from the ground (basic networking, DHCP, DNS, authentication) up through installation a queue/scheduler and scientific software.

    However, these tutorials and guides take some assumptions about users for granted, including basic Linux and Debian knowledge (see the Basic Linux Skills page for clarification and pointers to resources). This is not meant as an introduction to Debian or on how to cluster in general – thankfully, there are plenty of helpful tutorials and guides already in existence on those topics. A basic understanding of Debian and cluster technology will aid in following the tutorials.

  • Mobile-OTP: Strong Two-Factor Authentication with Mobile Phones – Mobile One Time Passwords (Mobile-OTP)
    strong, two-factor authentication with mobile phones

    Using static passwords for authentication, as it is commonly done, has quite a few security drawbacks: passwords can be guessed, forgotten, written down and stolen, eavesdropped or deliberately being told to other people.
    A better, more secure way of authentication is the so called "two-factor" or "strong authentication" based on one time passwords. Instead of authenticating with a simple password, each user carries a device ("token") to generate passwords that are valid only one time.

  • Open Monitoring Distribution – Wiki – OMD – Welcome to OMD – the Open Monitoring Distribution. OMD implements a completely new concept of how to install, maintain and update a monitoring system built on Nagios.

    OMD avoids the tedious work of manually compiling and integrating Nagios addons while at the same time avoiding the problems of pre-packaged installations coming with your Linux distribution, which are most times outdated and provide no regular updates.

    OMD bundles Nagios together with many important addons and can easily be installed on every major Linux distribution. We provide prebuilt packages for all enterprise Linux distributions and also for some other, such as Ubuntu 11.04.
