  • VPN over SSH – ArchWiki – There are several ways to set up a Virtual Private Network through SSH. Note that, while this may be useful from time to time, it may not be a full replacement for a regular VPN.
  • Simplify Your Life With an SSH Config File · Nerderati – If you're anything like me, you probably log in and out of a half dozen remote servers (or these days, local virtual machines) on a daily basis. And if you're even more like me, you have trouble remembering all of the various usernames, remote addresses and command line options for things like specifying a non-standard connection port or forwarding local ports to the remote machine[…]

  • 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.

  • 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.
