What is Zenoss?
The Zenoss project provides an integrated, easy-to-deploy and cost-effective opensource alternative for enterprise IT infrastructure monitoring. Unlike the big OSS companies (IBM, HP, CA, BMC, Amdocs) we are able to keep costs down and directly involve end users throughout the world. More details can be found here.

Put simply, Puppet is a system for automating system administration tasks. To learn more, read our big picture overview of Puppet, or take a deeper look at what Puppet can do with the Puppet Introduction. There's also an about Puppet page which gives the highlights of Puppet's functionality.
Having a digital ISDN telephone connection lets you easily integrate Fax and Answering Machine functionality into your Linux server. SuSE (and Debian) distribute a package called Capisuite for this purpose. You will also need a supported ISDN card (an AVM Fritz card is inexpensive and works).
The big issue is the Linux connectivity which became worse an worse over the time as Linux distribution getting more and more complicated. As matter of fact I did not find one instruction in the Internet on how to connect it to Linux via a cradle. Here is How!

If you have more than one server and you can't you afford outages during work hours (and maybe: work hours means from 0:00 - 23:59h each day), then you know the problem: You have to monitor your servers, the software|application and maybe some jobs on the
MultiTail lets you view one or multiple files like the original tail program. The difference is that it creates multiple windows on your console (with ncurses). It can also monitor wildcards: if another file matching the wildcard has a more recent modification date, it will automatically switch to that file. That way you can, for example, monitor a complete directory of files. Merging of 2 or even more logfiles is possible. It can also use colors while displaying the logfiles (through regular expressions), for faster recognition of what is important and what not. It can also filter lines (again with regular expressions). It has interactive menus for editing given regular expressions and deleting and adding windows. One can also have windows with the output of shell scripts and other software. When viewing the output of external software, MultiTail can mimic the functionality of tools like 'watch' and such.
