- How to write udev rules – Since the adoption of Kernel 2.6, Linux has used the udev system to handle devices such as USB connected peripherals. If you want to change the behavior when you plug something into a USB port, this section is for you. As an example, we will use a USB thumb drive but these methods should translate to any device handled by udev. As a goal for this exercise we decided to create a symlink and execute a script when a specific thumb drive was loaded.
- Persistent iSCSI LUN Device Name – jablonskis – […] I spent a bit of time figuring out how to get this achieved, so thought it is worth noting for the future reference. I will try to make this quick assuming you have knowledge about iSCSI software initiators in Linux[…]
- al3x/sovereign – A set of Ansible playbooks to build and maintain your own private cloud: email, calendar, contacts, file sync, IRC bouncer, VPN, and more.
- NSA-proof your e-mail in 2 hours | Sealed Abstract – You may be concerned that the NSA is reading your e-mail. Is there really anything you can do about it though? After all, you don’t really want to move off of GMail / Google Apps. And no place you would host is any better. Except, you know, hosting it yourself. The way that e-mail was originally designed to work. We’ve all just forgotten because, you know, webapps-n-stuff. It’s a lot of work, mkay, and I’m a lazy software developer.

- MySQL active-passive cluster | Your IT goes Linux – We will use the iSCSI Lun defined in our iSCSI cluster as a shared storage and we will run MySQL in active-passive (fail-over) mode using Pacemaker and Corosync cluster engine. The cluster will have to connect to the iSCSI target, mount the iSCSI partition on one node and start a MySQL service which has all its data on this partition.
- Perl – […] Perl has horrors, but it also has some great redeeming features. In this respect it is like every other programming language ever created. This document is intended to be informative, not evangelical. It is aimed at people who, like me: dislike the official Perl documentation at http://perl.org/ for being intensely technical and giving far too much space to very unusual edge cases learn new programming languages most quickly by "axiom and example" wish Larry Wall would get to the point already know how to program in general terms don't care about Perl beyond what's necessary to get the job done. This document is intended to be as short as possible, but no shorter[…]
- Linux Performance – This page links to various Linux performance material I've created, including the tools maps on the right, which show: Linux observability tools, Linux benchmarking tools, Linux tuning tools, and Linux observability sar. For more diagrams, see my slide decks below.
- AIXchange: Useful Storage Links – Here's an assortment of really good storage-related articles — the majority of which are found on IBM developerWorks — that are worth your time. While some of them are a few years old, they still provide relevant information.
These are my links for 24 lug 2012 from 12:40 to 14:51:
- Centrale di Mobilità – Muoviti responsabilmente senza pesare sull'ambiente
- www.vanheusden.com – AIX tips & tricks – AIX tips & tricks
(like: "Finding physical location of a disk" or why "AIX NFS server refuses client to mount share" and many other)
- Account Administration – disciplinux – Change AIX password non-interactively
Use the chpasswd utility to change the password.
- Tightening Default AIX Sendmail – disciplinux – I started looking at the default AIX configuration of sendmail for the SMTP Open Relay issues. Previously I had sent a configuration change to
allow only specific relay-domains. However, it appears that the default sendmail configuration sets "PROMISCUOUS_RELAY" which overrides the
- Configure sendmail to start logging Subject in maillog | www.linux4beginners.info – In this article we will learn how to configure sendmail so that you can log "Subject" in /var/log/maillog as by default sendmail does not log Subject to maillog file.
This is really interesting. Business people many times are interested in getting mail log files analyzed. To analyse mail logs they need various field to appera in mail logs. e.g. "From", "To", "Subject" etc from the sent email. By default sendmail logs From and To fields but it does not log Subject field. In this article you will learn how to enable sendmail to log "Subject".
