Puppet is a declarative language for expressing system configuration, a client and server for distributing it, and a library for realizing the configuration.
Rather than approaching server management by automating current techniques, Puppet reframes the problem by providing a language to express the relationships between servers, the services they provide, and the primitive objects that compose those services. Rather than handling the detail of how to achieve a certain configuration or provide a given service, Puppet users can simply express their desired configuration using the abstractions they’re used to handling, like service and node, and Puppet is responsible for either achieving the configuration or providing the user enough information to fix any encountered problems.
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!
Ora2Pg is a free tool used to migrate an Oracle database to a PostgreSQL compatible schema. It connects your
Oracle database, scan it automaticaly and extracts its structure or data, it then generates SQL scripts that you can
load into your PostgreSQL database.
Ora2Pg can be used from reverse engineering Oracle database to huge enterprise database migration or simply to replicate
some Oracle data into a PostgreSQL database. It is really easy to used and doesn't need any Oracle database knowledge than
providing the parameters needed to connect to the Oracle database.

Is it a bug or a feature that the solaris iscsi initiator isn't able to connect to an iscsi target on the same machine, using either the 127.0.0.1 localhost address or the machine's own ip address?
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

"Nix is a purely functional package manager. It allows multiple versions of a package to be installed side-by-side, ensures that dependency specifications are complete, supports atomic upgrades and rollbacks, allows non-root users to install software, and has many other features. It is the basis of the NixOS Linux distribution, but it can be used equally well under other Unix systems."

# * Unix socket authentication plugin is built-in since 10.0.22-6

# Needed so the root database user can authenticate without a password but

Also make sure needed record in table user has empty plugin field (there can be, for example, "unix_socket").
Since version 5.5.7 mysql has various auth plugins support https://dev.mysql.com/doc/refman/5.6/en/authentication-plugins.html
So if you have non-empty plugin field then password would be ignored and there would be warning at mysql error log (for me it's /var/log/mysql/error.log):
[Warning] 'user' entry 'root@localhost' has both a password and an authentication plugin specified. The password will be ignored.

For someone else that runs across this, when running mysql server 5.7.15, this actually locks your user out if you do not provide a plugin. Probably what you are looking for is a plugin of mysql_native_password. – Jonathan Cantrell Sep 28 '16 at 17:41
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.

tortunnel is a partial Onion Proxy implementation that's designed to build single-hop circuits through TOR exit nodes. This is useful for instances where you might want some very low level of anonymity and don't want to deal with the performance implications of using TOR's full three-hop circuits. It runs both as a SOCKS interface, and also exposes a fairly clean asynchronous C++ API to the TOR protocol itself. It was first written as a scanning tool for checking to see whether exit nodes were running sslstrip and is well suited for implementing other high-performance scanning routines against the TOR network as a whole. It might also be useful for implementing a perspectives-like interface for checking SSL, SSH, or other host certificates. It could be useful as an nmap scanning mode, or perhaps for something else entirely. To use the SOCKS interface, extract and compile the source. You will need the BOOST libraries in
n the event that something happens to a Xen virtual machine (VM) that prevents you from starting it, it's a good practice to have the virtual machine storage back end mounted in the Linux file system of the Xen-based server. By doing so, you'll be able to repair the VM quickly and painlessly. In this tip, I'll cover how to do this for physical devices that are used as storage back ends.
1. About this document This document contains general information, reference information and examples designed to help the user understand the moodss application.
Modular Object-Oriented Dynamic SpreadSheet (Moodss) is a graphical monitoring application with a complete graphical user interface (GUI) to conveniently monitor network services and send alerts when thresholds are crossed. Moodss is a deceptively simple tool that could characterized as a dynamic network-aware spreadsheet. It can poll devices using the Simple Network Management Protocol (SNMP), receive and send SNMP traps, and perform network service checks via Nagios plug-ins. It can optionally be used with the Modular Object-Oriented Multi-Purpose Service (Moomps) monitoring daemon to delegate monitoring tasks to a separate lightweight application after all thresholds have been defined with Moodss. The best way to see how Moodss operates is to walk through some examples so that’s what I’ll do in the steps below. I wish to give special thanks to Jean-Luc for his valuable assistance with Moodss on OS X, and for writing such a fine program.
The Dude network monitor is a new application by MikroTik which can dramatically improve the way you manage your network environment. It will automatically scan all devices within specified subnets, draw and layout a map of your networks, monitor services of your devices and alert you in case some service has problems.
The xen-vm-autosnapshot.py script has been updated with an important new option: –snapshot-tag. I still can’t believe I made such a silly oversight, but previous versions of this script had no way of differentiating between snapshots created automatically and those that were created manually. So if you happened to have some old manual snapshots lying around, the snapshot-rotate routine would have rotated them along with all the rest.
