  • Simplify Advanced Shell Scripting With Ruby | AIX | IBM Systems Magazine | System p, System p5, Power System | Ruby, SSH, shell scripting, Bull Freeware, sysadmin, – IBM Systems Magazine – Ruby is just for experienced programmers. right? False! Originating in the mid-1990s, Ruby is a fantastic language, made popular recently by the Web application framework—Ruby on Rails. It’s a massively flexible and easy language to learn. You can find Ruby for AIX in the AIX Toolbox at the Bull Freeware. The script we’ll be creating will do the following:

     

    * Go through a large list of servers.
    * SSH them and determine whether the server is AIX.
    * If so, it will go through all disks, returning their type.
    * It will do all of this completely in parallel in batch at 25 sub-processes at a time.

  • Recovering a lost partition table with a VMFS volume | vInfrastructure Blog – Vi possono essere diversi motivi che portano alla perdita della tabella delle partizioni o alla sua corruzione. Nel caso di datastore VMFS le possibili cause sono: resignature da un altro sistema (ad esempio il backup server, nel caso funzioni in SAN mode), un errore umano (basta eseguire, su dischi condivisi, da vSphere Client un Datastore / Delete da un ESXi non ancora collegato al vCenter Server), o anche a causa di qualche problema lato storage (mi è capitato proprio questo caso di recente su uno storage entry level)[…]

    (Mi è capitato, ho seguito la kb di vmware e ne sono uscito. Comunque sto sudando ancora adesso…)

  • Ubuntu Linux Resources – It's a collection of tutorials designed to help new Ubuntu users, in particular those coming from a Windows-using background.
  • PsPasswd – Systems administrators that manage local administrative accounts on multiple computers regularly need to change the account password as part of standard security practices. PsPasswd is a tool that lets you change an account password on the local or remote systems, enabling administrators to create batch files that run PsPasswd against the computers they manage in order to perform a mass change of the administrator password.

    PsPasswd uses Windows password reset APIs, so does not send passwords over the network in the clear.

  • Build a file server with the Raspberry Pi | Linux User – We’ll be using Arch Linux as the operating system for our file server, because it is small,and has only the minimum packages required for a working system. This means that we can set up the file server without wasting resources on a graphical user interface and other unnecessary packages. Arch Linux comes with hardly any RAM allocated to the GPU by default, which is exactly how we want it for use as a headless server.
  • Registry Settings that can be Modified to Improve Operating System Performance – This section provides a description of recommended values for several registry entries that impact operating system performance. These registry entries can be applied manually or can be applied via the operating system optimization PowerShell script included in Windows PowerShell Scripts.

  • Mail server statistics – The statistics are based on completely anonymous information and were performed using randomly chosen IP addresses. When connecting to a mail server defined as an MX in the domain configuration, it can reply in a different number of ways. It may not be online, or may be refusing connections. Also, it is possible that the server does not respond back with a "220" line within the period of time we wait, nor provide a banner that identifies the type of the software running on it, at all times.
  • Setting up backup mail exchange server with sendmail « Building systems that WORK – Setting up backup mail exchange server with sendmail

  • 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.

  • A TCP Proxy in Perl – good coders code, great reuse – Several weeks ago my friend Madars was in an airport in the Netherlands and he wanted to login into his server via ssh. It turned out that their public internet had only ports 80 and 443 open so he couldn't do that. He asked me if I could proxy either port 80 or 443 to his server. Surely, I had a solution. I modified the tcp proxy server that I had written for my Turn any Linux computer into SOCKS5 proxy in one command article and did:<br />
    sudo ./tcp-proxy2.pl 443 madars-server.com:22<br />

  • IPv6 Crash Course For Linux | Linux.com – […] You might be used to working with IPv4 on Linux, but like it or not IPv6 is on its way in. Roll up your sleeves, spit on your palms, and get ready to go to work because this is your crash course in actually using IPv6. It hardly hurts at all. Linux has supported it since the 2.1 kernel, so you shouldn't have to install anything. Make sure you have the ping6, ip, and ifconfig commands. […]
  • Another IPv6 Crash Course For Linux: Real IPv6 Addresses … – […] In the first IPv6 for Linux crash course, we covered some of the bare basics of IPv6 on Linux. Today we're going to learn how to use routable IPv6 addresses, some iptables rules to keep our experimentation from leaking out into the world, and about implementing DNS in IPv6 […]
