Scripting in the Current Novell Environment a Cheat Sheet by Johnnie Odom Anyone Can Script Scripting in the Current Novell Environment A Cheat Sheet By Johnnie Odom Anyone Can Script If you type it in the Terminal or Command Window, it can be scripted. If you can write a basic webpage, you can create a GUI for your scripts. If you learn any programming, you can get fancy with your scripts. And if you look around, you can steal or modify lots of existing scripts. What You Will Need A good text editor. On Windows: Notepad++ or Visual Studio Not Notepad. NOT WORDPAD! OS X: TextWrangler / BBEdit, Coda, TextMate Linux: Various based on religion (Seriously: Gedit, Vi, Emacs, nano, joe, jedit ...) Ideally a test environment. A server to run central scripts. Hint: SuSE / OES. A means to send desktop scripts to workstations. Hint: It’s ZENWorks What You Need to Find Out The path to the scripting engine. /usr/bin/php [Unix Style scripts begin with #!/path/to/engine] “C:\Windows\System32\cmd.exe” [ZENworks likes to know engine path.] What libraries are available? Libraries installed by default or at system install. Package system for installation of additional libraries. Most script libraries are just shims to system libraries. Google for documentation and scripting examples. Also, look at Cool Solutions and developer.novell.com And steal from Novell engineering (see what scripting files are included with the products.) How do I run arbitrary executables / shell commands? What facilities are available for error reporting and logging? System versus log file. Can I put a GUI on it or make it clickable? Novell / TAG Targets ZENWorks: Command Line Interface (zman and zac - “zman batch” is your friend!) Data Model OES / SuSE / eDirectory LDAP! Any traditionally scriptable component of Linux (i.e. everything) Screen-Scraping iManager GroupWise Current SOAP interface Upcoming RESTful admin interface eDirectory attributes Vibe Windows registry and Linux / OS X configuration files. NetIQ / SuSE Just about everything from these divisions has a firmly supported scriptable component. Workstation Targets Files Windows Registry Application-Specific Databases System commands Windows Options Traditional batch (cmd.exe) VBScript Powershell (Use this!) Other .NET languages as needed. Soon, lots of Javascript. Linux / OS X Options Shell + Unix Utils Perl PHP Python Ruby Expect - TCL CGI Javascript AppleScript / osascript Mono I Take Working Vacations A Few Words on Mono and .NET GUI targets keep shifting on Windows. If on Mono, use GTK# and install on Windows for cross-platform compatibility. Don’t use DirectoryService for eDirectory connections -- it does not support SSL on standard LDAP. Use the Novell C# LDAP libraries instead. Also, those are (somewhat) cross-platform. Mono is quite good now. Good for cross-platform solutions. LDAP Tips Use a raw LDAP tool like LDAP Browser (have to search for that one) to see how eDirectory really represents items. Use your imagination. Group-Like Things have two entries -- one in the group, and one in each member object. Always filter searches by object class to make sure you avoid getting other objects with similar names. CLI Vs. GUI CLI allows more flexible deployment and combination of scripts with other tools. GUIs allow users to self-service. If using a heavy environment (.NET), GUIs are fairly easy. On OS X, osascript can trigger AppleScript GUI events (buttons, text boxes). But the best GUI is the web. PHP of course, but also Perl, CGI, ruby, ASP etc. Demos Deploying Your Scripts Yes, you can still do one-liners in the NCP login script. ZENworks! Yes, it can move script files to HD and run them as a launch action, but ... Why not just run them direct as a ZENworks bundle? Run from mapped drive. File copy. System package format - .msi (Win), .pkg (OS X), rpm (Linux) Some Crazy Ideas Screen-Scraping iManager Novell Virtual File System XTier LibFLAIM Conclusion On the Unix side, check out Eric. S. Raymond’s “The Art of Unix Programming” Be sure to submit to Cool Solutions http://www.novell.com/communities/coolsolutions Write lots of code comments. Remove your site assumptions. Compose a friendly title page Fabulous Prizes! Have Fun!.

  • Why and How to Migrate from .NET to .NET Core. - Oliver Ray, Managing Director @ Number8
    Why and How to Migrate from .NET to .NET Core. - Oliver Ray, Managing Director @ number8 There’s no time like the present when it comes to paying down technical debt, investing in high-value features, and keeping up with development house-keeping. These practices allow development velocity to skyrocket. And For most companies still utilizing .NET, migrating to .NET Core is the most impactful technical investment they can make right now. This transition will simplify your teams’ development cycles and have a measurable impact on your bottom-line. However, it can also include unforeseen complexities and dependencies, so it’s crucial that the planning and prep work is done throughly. Our team at number8 took the time to detail a few high-level benefits that every team should consider during this transition. So, let’s get started. Why migrate from .NET to .NET Core? .NET Core 1.0 was announced in 2014 and aimed to bring the .NET framework into the open source world. The ultimate goal of this initiative was to make .NET projects more portable to other platforms. With the explosion of commodity platforms like Linux and ARM64 processors, .NET had to become more open to survive. From it’s initial release .NET Core has continued to evolve to leverage a wide range of technologies that allow teams to develop systems in whatever way they see fit. A significant example of this forward thinking was early support for Docker containers and Kubernetes. Teams Start Planning everywhere are trying to rethink core enterprise Now applications to fully see the benefit of cloud tooling.

  • Programming with Windows Forms
    A P P E N D I X A ■ ■ ■ Programming with Windows Forms Since the release of the .NET platform (circa 2001), the base class libraries have included a particular API named Windows Forms, represented primarily by the System.Windows.Forms.dll assembly. The Windows Forms toolkit provides the types necessary to build desktop graphical user interfaces (GUIs), create custom controls, manage resources (e.g., string tables and icons), and perform other desktop- centric programming tasks. In addition, a separate API named GDI+ (represented by the System.Drawing.dll assembly) provides additional types that allow programmers to generate 2D graphics, interact with networked printers, and manipulate image data. The Windows Forms (and GDI+) APIs remain alive and well within the .NET 4.0 platform, and they will exist within the base class library for quite some time (arguably forever). However, Microsoft has shipped a brand new GUI toolkit called Windows Presentation Foundation (WPF) since the release of .NET 3.0. As you saw in Chapters 27-31, WPF provides a massive amount of horsepower that you can use to build bleeding-edge user interfaces, and it has become the preferred desktop API for today’s .NET graphical user interfaces. The point of this appendix, however, is to provide a tour of the traditional Windows Forms API. One reason it is helpful to understand the original programming model: you can find many existing Windows Forms applications out there that will need to be maintained for some time to come. Also, many desktop GUIs simply might not require the horsepower offered by WPF.

    Securonix Threat Research: Detecting WastedLocker Ransomware Using Security Analytics Oleg Kolesnikov Securonix Threat Research Team Created on: July 28, 2020 Last Updated: August 18, 2020 Figure 1: Victim’s Systems Targeted by WastedLocker Unavailable (July 2020) The Securonix Threat Research Team (STR) is actively investigating the details of the critical targeted Wastedlocker ransomware attacks that reportedly already exploited more than 31 companies, with 8 of the victims being Fortune 500 companies [1], to help our customers detect, mitigate, and respond to such attacks. Here are some of the key technical details and our recommendations on possible Securonix predictive indicators/security analytics that can be used to detect the current and potentially future attack variants (these indicators may be updated as we receive more information.) 2 www.securonix.com Figure 2: WastedLocker/EvilCorp Attack in Progress - Targeting a Victim Company in a Recent High-Profile Attack Impact Here are the key details regarding the impact of the high-profile WastedLocker ransomware attacks/ EvilCorp malicious cyber threat actor(s)(MTA) involved: • The WastedLocker ransomware is a relatively new malicious payload used by the high-profile EvilCorp MTA, which previously used the Dridex trojan to deploy BitPaymer ransomware in attacks targeting government organizations and enterprises in the United States and Europe. (See Figure 1) • This MTA currently focuses on targeted “big game hunting” (BGH) ransomware attacks with multiple industry victims in recent months, with Garmin as one of the latest high-profile victims attacked (officially confirmed by Garmin on July 27). (See Figure 2) • The most recent ransom amount demanded was US$10M and appears to be based on the victim’s financial data.

This section provides you with the basic knowledge you need to get up and running with the most recent version of C#. Specifi cally, this chapter provides an overview of the .NET Framework and C#, including what these technologies are, the motivation for using them, and how they relate to each other. It begins with a general discussion of the .NET Framework. This technology contains many concepts that are tricky to come to grips with initially. This means that the discussion, by necessity, covers many concepts in a short amount of space. However, a quick look at the basics is essential to understanding how to program in C#. Later in the book, you revisit many of the topics covered here, exploring them in more detail. After that general introduction, the chapter provides a basic description of C# itself, includ- ing its origins and similarities to C++.
