Toller Artikel über SPAM-Quarantäne und Echtzeit Filterung.

Die Spam-Quarantäne des Münchener Landgerichts verschluckte wichtige E-Mails der Journalisten. Einem modernen Spam-Filter wäre das nicht passiert.

Interesting article about #IMAP protocol extensions.

A set of protocol extensions keeps the legacy IMAP 4 protocol usable, which also helps mobile clients. We present a healthful mix of useful extensions.

Great comparison of IMAP features #Dovecot vs. M$ Exchange 😉

So kommt es beispielsweise häufig vor, dass man ein Verzeichnis erstellt, eine Datei dort hineinkopiert und dann in dieses Verzeichnis wechseln will. Jedesmal den Verzeichnispfad neu zu tippen ist dabei unnötig, denn[Meta]+. kopiert das letzte Argument...

Edward J. Snowden, the former National Security Agency contractor who leaked details about American surveillance, personifies a debate at the heart of technology systems in government and industry: can the I.T. staff be trusted?

The feature list sounds very intersting.

Great article by Dan Walsh about #SELinux and using labels.

On the SELinux mail list today, someone asked: I want to store the logs from openswan into a different file ( /var/log/ipsec ) than the default. For this purpose I added plutostderrlog=/var/log/ipsec to ipsec.conf. As long as I keep the server in permissive mode, openswan…

Network Documentation Tool project

Netdot is an open source tool designed to help network administrators collect, organize and maintain network documentation.

In IPv6 this concept even replaced broadcasts completely, but unfortunately this part is completely missing in this article. But it is a good introduction in how it is implemented in IPv4.

IP multi-casting is a communication mechanism in which data is communicated from server to a set of clients who are interested in receiving that data. Any

Has someone experiences with Open-AudIT? Sounds interesting, but haven't heard about it before.

The network inventory, audit, documentation and management tool.

Very important for every sysadmin who needs to talk to customers.

Humans think in terms of mental models. In IT it is our responsibility to help them form accurate models as well as deal with inaccurate models that exist. Humans use mental models of how things work to fill in context. If we are not given the model, we make one up. This made-up model may be unrelated to how things actually work, but if it is suffi...

Great tutorial by Tom Limoncelli about what design patterns could provide for system administration.

Too bad these last two videos have broken audio

This is a really great story about how to debug network hardware problems.
@Lazy Admin

This is a technical article chronicling one of the most interesting bug hunts I’ve had the pleasure of chasing down. At AdGear Technologies Inc. where I work, ssh is king. We use it for management, monitoring, deployments, log file harvesting, even real-time event streaming. It’s solid, reliable, has all the predictability of a native unix tool...

Oh I want to see how this is working in practice. Hope we will deploy this soon at office so I can play with it.

Manchmal ist es hilfreich, einem Kollegen bei der Arbeit über die Schulter zu sehen.
