The X-ISP package implements a user-friendly interface to pppd/chat and provides maximum feedback from the dial-in and login phases on the browser screen. It saves a lot of time compared to configuring PPP manually. X-ISP has several advantages over manual configuration:
X-ISP enhances the user's knowledge of what is happening while a call is in progress in a graphical way, rather than the usual scripts that write output to the terminal.
X-ISP provides a mechanism to save ISP logs and to keep track of how many calls you make, their duration and cost.
One major facility is that the user can maintain two databases: one for the ISPs and the other for the phone companies (PTTs). This feature allows the user to configure his machine for more than one ISP and for more than one account with every ISP.
The phone company database supports all (known) PTT attributes applicable while logging phone-call costs, and saves its information in a separate file in the subdirectory /.xisplogs in the user's home directory.
X-ISP was developed by Dimitrios P. Bouras and can be downloaded at no charge from http://users.hol.gr/~dbouras/.
In order to install the X-ISP package on your system, four requirements must be satisfied:
The ppp-2.2.x package must be installed on the system.
X11R6 (XFree86 version 3.1.2 or newer) must be installed.
A copy of the XPM library (version 3.4 or later) is also needed.
Once these requirements are fulfilled, installation is straightforward. I have installed X-ISP on several machines (Slackware 3.4, kernel 2.0.30) by running make and make install. I was surprised I did not have to re-edit any configuration file or fix file permissions or anything. It worked perfectly from the first trial. However, in case you run into trouble, an explanation on solving your installation problems is in the documentation.
X-ISP comes with a large amount of technical documentation discussing implementation issues, security, architecture, and the interaction between the different components. It also has a good help facility that guides the user through setting up X-ISP step by step. Help is also available on-line from the main window.
X-ISP is a very well-thought-out tool. It gives us what we need: a fast way to configure the machine, graphical interface, a graphical control over the chat scripts, and a way to tracks time and cost.
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
