  1. If you aren't yet using Puppet or Chef for managing your *nix infrastructure, you should seriously consider it. The benefits are enormous. Frankly, I don't think you __can__ manage a modern infrastructure without using Puppet, Chef, or reinventing a configuration management framework with your own custom scripts. However, you can't use both Chef and Puppet together, so which should you choose?
  2. Blueprint reverse engineers servers Easy configuration management. Detect relevant packages, files, and source installs. Generate reusable server configs. Convert blueprints to Puppet or Chef. No DSLs, no extra servers, no workflow changes. Blueprint looks inside popular package managers, finds changes you made to configuration files, and archives software you built from source. It runs on Debian and RPM based distros with Python >= 2.6.

  5. Enabling HTTP Strict Transport Security on debian servers - I just enabled HTTP Strict Transport Security (HSTS) markers on a bunch of web servers that offer HTTPS. It's an easy step to take, and it means that users of HSTS-compliant browsers (such as Chromium and the upcoming Firefox 4) or browsers with HSTS-compliant extensions (like Firefox's NoScript or HTTPS-Everywhere) will no longer be vulnerable to attacks like sslstrip once they have made one successful connection to the HSTS-enabled HTTPS web site.

  6. Lohnt sich der Umstieg auf Syslog-ng? Ja, auf jedenfall. Syslog-ng bietet nicht nur wesentlich besser Filtermechanismen, sondern unterstützt beim Loggen über das Netzwerk nicht nur udp sondern auch tcp Datenverkehr, oder sogar Loggen in eine SQL-Datenbank. Wenn man stolzer Besitzer von Debian ist hat man es leicht ein aptitude install syslog-ng installiert nicht nur syslog-ng sondern entfernt auch den alten syslogd und klogd. Nach der erfolgreichen Installation ist Syslog-ng bereits Einsatzfähig, da Debian eine vordefinierte Konfigdatei liefert, in der die wichtigsten Logdateien auth.log, syslog, cron.log, daemon.log, kern.log, lpr.log, mail.log, user.log und uucp.log bereits eingetragen sind.
