Book Review: Building Network Management Tools with Tcl/Tk
Instructions for obtaining the sample code and the SNMP Tcl extensions are provided in the book. The sample code is available from Net Mgmt Solutions, Inc. and requires a login and password wich are provided in the book's preface. In order to access the download page, you must give your name, phone number and e-mail address, which is a bit much as far as I am concerned. Personally, I feel the book should have been packaged with a CD or floppy containing the latest releases of Tcl/Tk, Scotty and the sample code. The Scotty code was downloaded from the web.
This book provides a comprehensive overview of the use of Tcl/Tk to develop both stand-alone and web-based network management tools. If you are a network consultant or system administrator, it should provide you with a good starting point for the development of custom tools not present in your current tool set. The authors provide information about Tcl/Tk and the Scotty and Tickleman SNMP extensions to Tcl. With this information, you should be able to start with the code from any of their sample applications and tweak it into the network management tool that best meets your needs.
For readers wanting an introduction to Tcl/Tk and SNMP, I think this book serves well to a certain degree. If you are new to SNMP or networking, you may want to look on the Internet for a more complete introduction. As far as Tcl/Tk goes, the book does a fairly good job of describing things, but eventually you will need to augment it with a Tcl reference or programming primer. The authors list (at the end of Chapter 15) additional books, newsgroups and web sites that provide information about SNMP, Tcl/Tk and network management in general.
Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
