  • CloudInit – Community Help Wiki – cloud-init is the Ubuntu package that handles early initialization of a cloud instance. It is installed in the Ubuntu Cloud Images and also in the official Ubuntu images available on EC2. Some of the things it configures are: setting a default locale setting hostname generate ssh private keys adding ssh keys to user's .ssh/authorized_keys so they can log in setting up ephemeral mount points cloud-init's behavior can be configured via user-data. User-data can be given by the user at instance launch time. This is done via the –user-data or –user-data-file argument to ec2-run-instances
  • Tsunami UDP Protocol – Tsunami UDP Protocol: A fast user-space file transfer protocol that uses TCP control and UDP data for transfer over very high speed long distance networks (≥ 1 Gbps and even 10 GE), designed to provide more throughput than possible with TCP over the same networks. The project is based on original Indiana University 2002 Tsunami source code, but has been significantly improved and extended. As such, large portions of the program today are courtesy by Aalto University Metsähovi Radio Observatory. Includes FTP-like client and server command line applications for normal file transfers. It has additionally been extended for high rate real-time data streaming in eVLBI radio astronomy and geodesy (VSIB, PCEVN DAQ). Licensed under the original IU open source license.

  • Nuova “vecchia” vita per il Samsung NC10 | Gioxx’s Wall – Il mio vecchio Samsung NC 10 mi ha servito egregiamente negli anni passati e dopo un upgrade di RAM ed una prossima sostituzione disco può ancora rivelarsi un fidato compagno di lavoro per chi non necessita di prestazioni particolarmente elevate. Ad Ilaria basta ad esempio navigare in internet (Firefox), gestire la posta elettronica (Thunderbird) e utilizzare la suite Office di Microsoft, che funziona ancora perfettamente in coppia con l’anziano sempreverde Windows XP, si, proprio lui!

    Ecco quindi cosa fare con una chiave USB da 512 MB o più (ne avete ancora una in giro, ne sono quasi certo, nascosta da qualche parte) che verrà utilizzata una prima volta per installare il sistema ed una seconda per effettuare un backup completo del disco pronto.

  • Changing Windows RDP port | MWalker | Technology Cadre – Sometimes it's nice to change the default listening port of the Remote Desktop Protocol (RDP) service. Running standard services on non-standard is a simple way to avoid scripted attacks against your systems. Turns out changing the RDP port is as simple as a registry setting and a reboot.
  • Portable-VirtualBox | Download of Portable-VirtualBox – Portable-VirtualBox is a free and open source software tool that lets you run any operating system from a usb stick without separate installation.

  • Join di una macchina RHEL a un dominio Active Directory Windows e uso dei dischi condivisi dal dominio – Mia mamma usa Linux! – Questo documento descrive, in salsa cookbook, come realizzare il join di una macchina Red Hat Linux Server versione 6 ad un dominio Active Directory realizzato con Windows server 2003 o 2008.

    Segue una seconda parte che descrive come poter montare i dischi esposti da Windows ed usarli in scrittura e lettura.

  • Modern Perl – download ePub, HTML, Mobipocket – Perl.it – Modern Perl, scritto da chromatic è un libro sul linguaggio Perl adatto ai programmatori di tutti i livelli.

    Per chi si avvicina al linguaggio, il libro costituisce una introduzione a Perl aggiornata e moderna, che permette di prendere confidenza con il linguaggio utilizzandone gli strumenti e le metodologie sviluppate negli ultimi anni.

    Per il programmatore più esperto, Modern Perl costituisce un ideale aggiornamento su tutto quanto è stato introdotto con perl 5.12 e 5.14.

  • TCP Port Scanner in Bash – good coders code, great reuse – I just had this quick idea to write a tcp port scanner in bash. Bash supports the special /dev/tcp/host/port file that you can read/write. Writing to this special file makes bash open a tcp connection to host:port. If writing to the port succeeds, the port is open, else the port is closed.

  • How to get unrestricted root access to HMC? « I am vistababa! – Using GUI interface of HMC, you can’t do everything you like! You just can use predefined features of GUI. For example, you can’t schedule every commands you want, or you can’t run a command remotely on clients from HMC, and so on.
  • Get your Dell Service Tag number via the Linux (or Windows) command-line – Brandon Checketts – When your server is located in a data center far away, it makes it difficult to walk over to the box and read the service tag off of it. Fortunately, the Service Tag is stored somewhere in the system BIOS, and is accessible with the ‘dmidecode’ utility.
  • TCP Traffic Analyzer (Yahoo! Developer Network Blog) – You probably have questions like these about traffic on a TCP (Transmission Control Protocol) server (or client):<br />
    <br />
    * How many connections lasted more (or less) than X milliseconds?<br />
    * How many connections needed more than N attempts to succeed?<br />
    * What is the distribution of connection duration or connection throughput?<br />
    * What is the distribution of connection duration or throughput for connections in which the server or client sent more than N bytes?<br />
    * What specific IP addresses and ports had connections that lasted between 50 and 100 milliseconds long?<br />
    <br />
    You can get answers to these questions (and more) using Yahoo!'s TCP Traffic Analyzer (yconalyzer), available as an open-source project via free download.

  • pwnat – NAT to NAT client-server communication – pwnat, pronounced "poe-nat", is a tool that allows any number of clients behind NATs to communicate with a server behind a separate NAT with *no* port forwarding and *no* DMZ setup on any routers in order to directly communicate with each other. The server does not need to know anything about the clients trying to connect.

  • Unix File and Directory Permissions and Modes – Unix and Linux systems (including Mac OS X and other POSIX compliant systems) have a (relatively) simple system for controlling access to files and directories. This system is defined in POSIX.1:2008 standard external link, also known as the Single Unix Specification (SUS version 4). And since devices such as disks, ports, etc. have file names (under /dev) you control access to them the same way. (Note Windows systems up through Windows ME don't support permissions, just a "read only" attribute.)

If you want to learn more than just how to set up or manage virtual printers on AIX, this article is for you. Most successful AIX and UNIX administrators thrive on learning more about the system they administer. Printing is only one facet of their system, but it's an important one to know.
