  • Squid kerberos authentication and ldap authorization in Active Directory « Klaubert’s Blog – The squid web cache include a authenticator for kerberos, it is simple to use, but the documentation is not very clear about how to make it work. Below some steps use by me to make Squid 3.0 Stable1 and Squid 2.6 Stable17 authenticate against Active Directory (Windows 2003 Directory Service) and also to make it make the authorization using Ldap. This setup was not used in production environment yet, so its possible to had some problems not seen by me or scalabilities issues.
  • active directory – Getting Squid to authenticate with kerberos and Windows 2008/2003/7/XP – Server Fault – This is setup with Squid 3.0, has also been tested with Squid 3.1 and should work with Squid 2.7. Your Windows user must be a member of the SQUID_USERS group in Active Directory (for this case anyway).

    On the Windows side, Windows XP and Windows 2007 have been tested against Windows 2008, and Windows XP against Windows 2003.

  • 10 Ruby One Liners to Impress Your Friends – Someone came up with a list of 10 one-liner examples that are meant to showcase Scala’s expressiveness. A CoffeeScript version quickly emerged, so I thought I’d publish a Ruby one. I find Ruby’s syntax to be a bit cleaner than Scala’s, but the substance (at least as far as these examples are concerned) is relatively similar.
  • Ruby development for system administrators | Linux User – Most Linux and UNIX system administrators use a diverse mix of shell scripts and tools like grep, awk, cut and so on. The classical approach has proven its merits, but these scripts are generally not easy to read or to maintain. One solution is to use a real programming language for system administration tasks. In a complex environment, system administration can become much easier with a real programming language instead of shell scripts. Traditionally, Perl has been very popular among sysadmins, but some people maintain that this is not much better than shell.

    In this article, we choose Ruby, a feature-rich but simple object-oriented programming language known from the popular web application framework Ruby on Rails. T

  • Modern Perl, by chromatic – Onyx Neon Press – Modern Perl is one way to describe how experienced and effective Perl 5 programmers work. They use language idioms. They take advantage of the CPAN. They're recognizably Perlish, and they show good taste and craftsmanship and a full understanding of Perl.

    You can learn this too, whether you've dabbled with Perl for a decade or someone just handed you this book and said "Fix this code by Friday."

  • Useful commands for Windows administrators – Managing a Windows 2000 Active Directory with about 100 servers, over 1500 computers and 35 sites, the following commands often helped me answer questions or solve problems.
    Most commands are "one-liners", but for some I had to make an exception and go to the right directory first.

    These commands could all be used in batch files, though some may need some "parsing" with FOR /F to retrieve only the required substrings from the displayed information.

    PNP4Nagios 0.6.7
    MK Livestatus 1.1.8
    Cacti/Spine 0.8.7g
    Smokeping 2.3.6
    OpenNMS 1.8.5

    You can start immediately. It is especially suitable for comparing these different monitoring solutions. Note that OpenNMS is written in Java and produces a high load on the system. Starting and Stopping OpenNMS takes a long time (several minutes!).

  • Squid Block – DNSBL Redirector for the Squid Proxy – dnsbl_redir is a shamelessly derived redirector based on the asqredir redirector written by Thomas Zippo < thomas at zippo dot ch >. Thanks!
    Its been rewritten to use a DNSBL list (RHS type) to check for and block sites listed in the DNSBL. It will redirect your users to the page/site listed in the top of the dnsbl_redir.h file.

    dnsbl_redir is written in C. It consists of one small source file and a small(er) .h file. It has been tested and runs on the current Squid versions. It performs very well on Linux (RedHat/Fedora), BSD and technically should compile and run on any gnu/linux.

  • CoolSQL-Database-JDBC, Ibatis-Ibator(Abator) – CoolSQL is a cool tool used to view and manage database. It provides a nice user interface which makes a wonderful experience to user. CoolSQL inclineds to view and analyze data in the database, provides abundant functions including querying, modifying, exporting, supporting sqlscript and analyzing data. Convenience and maneuverability are the most advantages of CoolSQL. CoolSQL is written in java, thus it should run on any operating system that provides a Java Runtime (1.5 or above).
  • ottimizzazioni (quasi) estreme – In fondo, perché far ricomprimere ad Apache lo stesso file centomila volte al giorno, se questo non cambia praticamente mai? Non sarebbe possibile comprimerlo “a priori” e poi istruire il server a fornire la giusta versione a seconda che il browser dell’utente supporti o meno il formato gzip? A quanto pare la risposta è si
  • Trouble-Maker – Being a system administrator is full of interesting challenges. We like this. However, some of these challenges can be problematic, if they cause service interrupts on production systems. Most system administrators have run into the situation where something is wrong, the server is down, and we don't know what is going on. This project attempts to help.<br />
    <br />
    There are a lot of tools out there to make the system administrator's life easier. However, no tool is a replacement for properly understanding the system and experience in troubleshooting unknown situations. This is where Trouble-Maker comes in. Unlike other projects, we do not attempt to solve problems — we cause them.
  • iScanner – Remove website malwares, web pages viruses and malicious codes – iScanner is a free open source tool lets you detect and remove malicious codes and web page malwares from your website easily and automatically. iScanner will not only show you the infected files in your server but it's also able to clean these files by removing the malware code ONLY from the infected files.<br />

    Before I start with this article I'd like to start by saying that abusing the .htaccess file will hurt the performance of your website. The .htaccess file should only be used if you have no other way to achieve certain things.<br />
    Make sure to back up your current .htaccess file before applying any of the following hacks. […]<br />

  • Keeping an eye on TSM volumes – […] I wrote a quick script which tells me when volumes in TSM (Tivoli Storage Manager) have access and/or media issues and shoots me off an email. The script does two things:<br />
    1) Checks for volumes which are NOT in the states READWRITE or OFFSITE.<br />
    2) Checks for volumes which have a read/write error count >0.<br />
    I’m sure that most people running TSM in their environment have some sort of daily reporting that gets sent out. If that’s the case, you can simply extract the SQL from the script and use it in your own reporting tools.<br />

  • Puppet is system administration – Automated. – Puppet is a declarative language for expressing system configuration, a client and server for distributing it, and a library for realizing the configuration.
    By saving you countless hours of frustration, monotony, and/or reinventing the wheel, Puppet can change your life. Here are some key points about Puppet:
    Puppet lets you perform normal administrative tasks (such as adding users, installing packages, and updating server configurations) on any number of systems, even if those systems are running completely different operating systems. Through the use of providers, Puppet takes a generic instruction from you (such as ensuring MySQL is installed) and performs the task the "right way" for each system.
    Whether you have a small, heterogeneous network of user workstations or a cluster of rack-mounted number-crunchers, Puppet can help reduce your overhead and get the everyday management of your network under control so you can concentrate on the real problems.
