  • Filtering Apache logs / conditional Logging – This can be very troublesome when trying to access certain web pages. The only way to get through is to make use of conditional logging (it is not the only way to control the contents of the logs) To do this, simply define an environment variable ,according to certain criteria, then request that the server does not write the file type within log when this variable exists
  • TestSSLServer – TestSSLServer is a simple command-line tool which contacts a SSL/TLS server (name and port are given as parameters) and obtains some information from it: Supported versions (among SSL 2.0, SSL 3.0, TLS 1.0, TLS 1.1 and TLS 1.2).

  • Clustering with JBoss mod_cluster – jboss cluster – JBoss application server tutorials – Mod cluster is an http based load balancer which greatly simplify the setup of an http cluster. It ships as a set of modules which need to be installed on the httpd server and a Service Archive Library (.sar) which needs to be deployed on JBoss AS (It is built-in in JBoss AS 6/7).   Compared with the former mod_jk, the new mod_cluster has the great advantage to accept a dynamic configuration of httpd workers. This can be done through an advertise mechanism where all httpd workers communicate lifecycle events (like startup or shutdown) thus leveraging dynamic configuration of nodes.
  • How to configure mod_cluster with JBoss ? « JBoss – Like mod_jk, mod_cluster is also a httpd based load balancer which uses a communication channel to forward requests from the httpd to one of a set of application server nodes. So the question comes Why mod_cluster ? To answer this question we will let you know few advantages of mod_cluster over mod_jk and other httpd-based load balancers.

  • harelba/q · GitHub – Have you ever stared at a text file on the screen, hoping it would have been a database so you could ask anything you want about it? I had that feeling many times, and I've finally understood that it's not the database that I want. It's the language – SQL. SQL is a declarative language for data, and as such it allows me to define what I want without caring about how exactly it's done. This is the reason SQL is so powerful, because it treats data as data and not as bits and bytes (and chars). The goal of this tool is to provide a bridge between the world of text files and of SQL. q allows performing SQL-like statements on tabular text data.

  • kaniini/tpe-lkm · GitHub – Trusted Path Execution is a security feature that denies users from executing programs that are not owned by root, or are writable. This closes the door on a whole category of exploits where a malicious user tries to execute his or her own code to attack the system. Since this module doesn't use any kind of ACLs, it works out of the box with no configuration. It isn't complicated to test or deploy to current production systems. Just install it and you're done!

  • Centralizzare i log mediante Elasticsearch, Logstash e Kibana – Mia mamma usa Linux! – Uno dei principali problemi che si rilevano in fase di debug delle anomalie relative ad applicazioni è la frammentazione delle informazioni. Tanti log, buona parte dei quali inutili, sono sparsi ovunque nelle macchine interessate all’erogazione di questo o quel servizio.
    Tipicamente quando si tratta di servizi ripartiti su più macchine è sempre necessario aprire diverse console all’interno delle quali, per ciascuna macchina, il (o i) file di log vengono aperti, filtrati stampati e via così, sino ad ottenere una situazione degna di Sherlock Holmes, in cui solo consumati ed abili detective riescono a trovare l’indizio che sfugge ai più.

    Esiste però una via migliore per gestire enormi quantità di log in una forma centralizzata, facilmente ricercabile e che usi un’interfaccia gradevole. Si tratta della combinazione di tre software: Elasticsearch, Logstash e Kibana.

  • MQTT and Arduino Devices – IBM Redbooks – The number of different types of devices that can benefit from MQTT implementations is growing every day. This paper shows how to use MQTT directly from the Arduino platform.

  • MQTT: MQ Telemetry Transport – MQTT is a machine-to-machine (M2M)/"Internet of Things" connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium. For example, it has been used in sensors communicating to a broker via satellite link, over occasional dial-up connections with healthcare providers, and in a range of home automation and small device scenarios. It is also ideal for mobile applications because of its small size, low power usage, minimised data packets, and efficient distribution of information to one or many receivers (more…)
  • SoftPerfect Network Scanner: fast and free network scanner – SoftPerfect Network Scanner is a free multi-threaded IP, NetBIOS and SNMP scanner with a modern interface and many advanced features. It is intended for both system administrators and general users interested in computer security. The program pings computers, scans for listening TCP/UDP ports and displays which types of resources are shared on the network (including system and hidden).
    In addition, it allows you to mount shared folders as network drives, browse them using Windows Explorer, filter the results list and more. SoftPerfect Network Scanner can also check for a user-defined port and report back if one is open. It can also resolve host names and auto-detect your local and external IP range. It supports remote shutdown and Wake-On-LAN.

  • 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.

  • E-MailRelay — SMTP proxy and store-and-forward MTA – E-MailRelay is a simple SMTP proxy and store-and-forward message transfer agent (MTA). When running as a proxy all e-mail messages can be passed through a user-defined program, such as a spam filter, which can drop, re-address or edit messages as they pass through. When running as a store-and-forward MTA incoming messages are stored in a local spool directory, and then forwarded to the next SMTP server on request.

    Because of its functional simplicity E-MailRelay is easy to configure, often only requiring the address of the target SMTP server to be put on the command line.

    E-MailRelay can also run as a POP3 server. Messages received over SMTP can be automatically dropped into several independent POP3 mailboxes.

    C++ source code is available for Linux, FreeBSD, MacOS X etc, and Windows. Distribution is under the GNU General Public License V3.

  • Monitor Your Website in Real-Time with Apachetop – How-To Geek – As a webmaster, I’ve often wanted to be able to see real-time hits as they arrive. Sure, Google Analytics is a wonderful package for looking at trends over time, but there’s a delay of a few hours there, and you really can’t see data like requests per second or total bytes.

    This is where the apachetop utility comes in. It’s a very simple command line utility that you can use to monitor traffic real-time. It accomplishes this by parsing the apache logfiles and displaying meaningful output to the screen.

  • Ashwin Jayaprakash’s Blog: The little gem that is BusyBox (for Windows) – As a Windows user (no shame) I have, for years searched for a simple GNU-like toolkit – grep, awk, tail and other such goodies enjoyed by Linux users. Yes, there's Cygwin but it's a beast – too big and a pain to install. Sometimes, I've even resorted to starting a Linux VMWare image just to run a simple awk script to munge some log files.
