  • Using Foreman, an Opensource Frontend for Puppet – – The recent vulnerability in bash, got me running to update bash. It’s easy when you have maybe one or two Linux servers, but what do you do if you have 100’s or even thousands or servers? You need to use a server configuration and management tool like puppet. However, instead of using the command line, I wanted a GUI tool where I could select the servers or server group and select an action. That is where I found Foreman, A opensource tool which not only handles configuration of your servers but also does provisioning. Foreman is easy to install, opensource, has community based support and a good deal of documentation.
  • Power Up Your Authentication with Open LDAP and Puppet | DataCentred – When you’re busy automating your infrastructure, a recurring theme that causes questions and problems is this: how do you reliably integrate your data (which changes all the time) into your configuration? As a hosting company, we find ourselves needing to tend to an ever-increasing number of devices: servers, switches, routers, hypervisors, you name it. A staple mechanism for centralised authentication is the use of an LDAP server to manage a directory of users and groups and to perform authentication of credentials and privileges on behalf of other devices on the network.
  • Enterprise/Authentication/KerberosServices – Ubuntu Wiki – This article explains a little bit about the Kerberos protocol and how it can be used in Ubuntu. It's not a thorough manual, use more authoritative sources to get more accurate information and update if you see obvious mistakes.

  • ottimizzazioni (quasi) estreme – In fondo, perché far ricomprimere ad Apache lo stesso file centomila volte al giorno, se questo non cambia praticamente mai? Non sarebbe possibile comprimerlo “a priori” e poi istruire il server a fornire la giusta versione a seconda che il browser dell’utente supporti o meno il formato gzip? A quanto pare la risposta è si
  • Trouble-Maker – Being a system administrator is full of interesting challenges. We like this. However, some of these challenges can be problematic, if they cause service interrupts on production systems. Most system administrators have run into the situation where something is wrong, the server is down, and we don't know what is going on. This project attempts to help.<br />
    <br />
    There are a lot of tools out there to make the system administrator's life easier. However, no tool is a replacement for properly understanding the system and experience in troubleshooting unknown situations. This is where Trouble-Maker comes in. Unlike other projects, we do not attempt to solve problems — we cause them.
