Java Telnet Application

Can Tilera take on Intel with "ultimate" Cloud Computing processor?

The company is introducing what it claims, perhaps with a tad over-zealous grandiosity, is the ultimate Cloud Computing processor. The TILE Gx 3000 family, to give it its more prosaic title, is based around a 64-bit core, and comes in 36, 64 and 100-core versions. Many will feel that its biggest claim to fame, however, is the company’s expectation that it will consume 80% lower Wattage than Intel’s just-announced Sandy Bridge Xeon, coupled with a claimed 10x performance per Watt advantage over the Intel device. Some will, of course, argue about such headline figures, particularly over whether eggs are being compared to eggs. I intend to return to this in more depth in my personal blog at http://www.lian-james.com/banks-statement/ for the detail is interesting. For the majority of Cloud users, however, such esoteric discussions are secondary. What do they get that’s of value: that is the real question. Here, the fundamental questions concerns Linux. That is the operating system for which Tilera’s 3000 system is designed. For a lot of dedicated web users Linux is the bee’s knees to work with, yet for a large number of traditional corporate users, particularly those now really starting to look at the cloud as a serious component of their business operations, Linux is still an operating system to be viewed behind the splayed fingers of both hands. Yet for that latter group there are some observations worth making. For a start, though their world is often largely geared to `general purpose’ computing the Cloud does change many of the rules of operation if it is to be exploited successfully. It is heavily based on the application of standards, and they all run well on Linux. In addition, most of the applications that are now increasingly dominant in the Cloud, particularly for the newer applications and services that give the Cloud most of its operational advantages, have come from the open source community. That is just about exclusively Linux-based. Now Tilera’s Director of Marketing, Ihab Bishara, would be the last to suggest that this Linux orientation classifies the 3000 family for the sobriquet of `general purpose’. He would also be amongst the first to observe that one of the reasons the processor offers much higher performance than Intel’s Sandy Bridge is that it is not designed to stand ready to process tasks that are only required on special occasions.

“Reaching the OPAC –Java Telnet”in Ariadne:the - Bill the Librarian

The Problem and a Solution

Many remote users of our library catalog [1] have difficulty accessing it via telnet or dial-up for several reasons. It is available via telnet through a URL on our homepage [2] . Some problems using the OPAC include:

Wrong terminal emulation Terminal emulation does not include special keys Lack of telnet software No technical support from their service providers

Possible solutions include providing all remote users with software,provide technical support for multiple packages,or ignore the problem. None of these solutions is feasible because of lack of staff and money. We couldn’t ignore the problem because we are a service oriented organization. After looking around for several months,I stumbled across Java Telnet.

Java Telnet is a Java based applet. It provides full terminal emulation for a telnet session within a web page. It is authored by Matthias L. Jugel and Marcus Meißner. It is available over the Internet for downloading at the Java Telnet homepage [3] . The Java Telnet package is freely available under the GNU Library General Public License  [4] ,popularly know as “copyleft”. Java Telnet is available in compressed format and must be “unzipped”. The package contains three major parts:

telnet connection services. Terminal emulation. modules for configuration and local control over “look and feel”.

Using a Java based package offers many advantages among which include no need for a separate telnet program,cross-platform (at least potentially),can be used by different brands of browsers,and requires no set up by the user. It does require a Java capable browser and a microcomputer with the power to run that browser.

The applet was developed by two computer people in Germany. Matthias L. Jugel (a graduate of University of London,Birkbeck College) is employed by the German National Research Centre for Information Technology. Marcus Meißner is a Computer Science student at the University of Erlangen. He’s almost done with his diploma (MSc). Mr. Jugel “started to program the first version of the applet as a very simple thing to learn Java. When it became clear that it may be useful I asked Marcus to help me.”Both authors are involved in text-based virtual realities (called MUDs) and the applet would be a useful client to access the MUDS.

Installation and Setup

Installation and set up is simple compared to many software packages. The first step is to uncompress the software. The compressed package is available in a UNIX tgz file or as a Windows NT/95 zip file. Special care must be taken in using the uncompression program in that the directory structure must be maintained. The software must also be housed on the same machine that the telnet session will run on. This is do to security restrictions built into Java. It is possible to “redirect”a session to another telnet via a proxy server. Details on how to do that are in the package. The files use long file names so if your system should be one that allows long file names. Otherwise you will have to rename files and any of the html references will not work in the documentation and example files. After installing all of the files,make sure that they are readable by other users.
