  • Howto: Change the IP address of a Dell 4/P DRAC from the command line without rebooting the server – Normally you configure a Dell Remote Access Card (DRAC) when a server is initially commissioned. Once the card is set, administrators rarely if ever need to modify the settings. If you do need to change the settings, the server needs to be restarted so the DRAC BIOS can be modified, which obviously results in system downtime and requires a physical presence at the server console.
  • bash ini parser | /var/log/ajdiaz – In some situations i like to use INI files as configuration files, as python do. But bash do not provide a parser for these files, obviously you can use a awk code or a couple of sed calls, but if you are bash-priest and do not want to use nothing more, then you can try the following obscure code:
  • Jugg Monkey: VMWare HA Agent had an error – I recently had a problem with one hoste in a 3 node VMWare ESX 3. 5 cluster. For some reason, the HA Agent would not start after I applied outstanding software updates. I kept receiving "VMWare HA Agent had an error" in the alerts after the host came online. I had recently needed to change the IP address of the VMWare 3.5 ESX host, so I figured that was the root cause.

  • 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
    RELAY-DOMAINS directive.
  • 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".

  • gitso – Gitso is to support others. – Google Project Hosting – Gitso is a frontend to reverse VNC connections. It is meant to be a simple two-step process that connects one person to another's screen. First, the support person offers to give support. Second, the person who needs help connects and has their screen remotely visible. Because Gitso is cross-platform (Linux, OS X and Windows) and uses a reverse VNC connection, it greatly simplifies the process of getting support.
