Focus on Software
I am excited about Samba 2.0 and its new web interface called swat. However, there is still room for smaller, simpler tools that are found in the Samba package or do not require a web browser. We will look at a few of these tools today as well as a few graphical FTP packages.
gtksamba is a nice program that aids configuration and testing of the Samba smb.conf file. The smb.conf file to edit can be specified, if it has a different name or is located in a directory other than /etc. While not as detailed as swat, it allows a user with proper permissions to look at and edit smb.conf. This program appears just as powerful as swat, but does not require a web browser. Some features planned for this program are not yet implemented, such as the ability to configure remote machines. For its help, gtksamba uses the Samba man pages. However, it does not just present the man pages—it parses them to make finding specific parameters easy. In all, gtksamba is a well-thought-out program. It requires gtk 1.1.13, glib, Xext, X11, libm and glibc.
A Tcl/Tk interface to the smbclient program in Samba, TkSmb allows browsing of the “Network Neighborhood” in a box on your screen. Shown are the neighborhood hosts, the shares on any particular host, the different groups detected, and when a share is selected, the files in the share. Files and directories are displayed in black and blue respectively. One security aspect requires you enter your password each time you change shares. A check box to “remember my password” for the current session would be helpful. It requires Tcl/Tk 8.0, expect 5.24+ and glibc 2.0.6.
The smb2www package provides a view of the “Network Neighborhood” through a web browser and more closely resembles the Microsoft version. While nice, installation is a little difficult; the script walks you through questions, but could be a bit more friendly. Different hosts (Windows 9x or NT) show up as different icons—a nice touch. It requires a working web server (either Apache or another), Perl and a web browser.
Under Windows, users have the ability to send each other messages if the messaging facility is turned on. The LinPopUp utility allows Linux Samba servers to exchange messages with Windows hosts or other Samba servers. It requires a change to the smb.conf file by root for messages to be received, but they can be sent without this modification. This facility will also receive messages from the NT server. It requires gtk 1.0.4+, Xext, X11, libm, Xmu, Xt, SM, ICE and glibc.
tkchooser2 is another browsing tool that can be used with or without Samba. The default configuration is for AppleTalk (Netatalk) to be installed; however, this is easily changed. What this package lacks is a way to configure everything without opening several files and making changes. While the instructions are adequate, most newbies will not feel comfortable reconfiguring the package. Once a package is stable and ready for release, I would consider a configuration script that walks installers through initial setup a must. It requires Tcl/Tk 8.0.
gftp provides drag and drop for X. It is a well-done package that will help anyone move files around the Net. For doing file transfers, gftp is the easiest to use graphical utility I have seen, and it allows multiple transfers at one time (if you have the bandwidth for it). Partial transfers can be resumed. Two windows below the two side-by-side directory windows allow you to watch transfers and messages from the host. An easy connection manager rounds out this utility. Utilities like this make it easy for newbies and give them one more reason to choose Linux. It requires libpthread, gtk 1.1, Xext, X11, lib and glibc.
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
