We are beginning with these four terms: master, slave, blacklist, and whitelist. Because of the enormity of this endeavor, these changes will be implemented gradually over several upcoming releases. For more details, see our CTO Chris Wright’s message . 3 Migration Toolkit for Applications 5.0 Web Console Guide CHAPTER 1. INTRODUCTION 1.1. ABOUT THE WEB CONSOLE GUIDE This guide is for engineers, consultants, and others who want to use the Migration Toolkit for Applications (MTA) to migrate Java applications or other components. It describes how to install and use the web console to manage migration projects and analyze applications. 1.2. ABOUT THE MIGRATION TOOLKIT FOR APPLICATIONS What is the Migration Toolkit for Applications? The Migration Toolkit for Applications (MTA) is an extensible and customizable rule-based tool that simplifies the migration of Java applications. The MTA examines application artifacts, including project source directories and application archives, then produces an HTML report that highlights areas needing changes. MTA can migrate Java applications from earlier versions of Red Hat JBoss Enterprise Application Platform or from other application servers, such as Oracle WebLogic Server or IBM WebSphere Application Server. How does the Migration Toolkit for Applications simplify migration? The Migration Toolkit for Applications looks for common resources and highlights technologies and known trouble spots when migrating applications. The goal is to provide a high-level view into the technologies used by the application and provide a detailed report organizations can use to estimate, document, and migrate enterprise applications to Java EE and Red Hat JBoss Enterprise Application Platform. How do I learn more? See the Introduction to the Migration Toolkit for Applications to learn more about the features, supported configurations, system requirements, and available tools in the Migration Toolkit for Applications. 1.3. ABOUT THE WEB CONSOLE The web console for the Migration Toolkit for Applications allows a team of users to assess and prioritize migration and modernization efforts for a large number of applications. It allows you to group applications into projects for analysis and provides numerous reports that highlight the results. 4 CHAPTER 2. INSTALLING THE WEB CONSOLE CHAPTER 2. INSTALLING THE WEB CONSOLE You can install the web console on Linux, Windows, macOS, or OpenShift Container Platform. 2.1. INSTALLING THE WEB CONSOLE ON LINUX, WINDOWS, OR MACOS You can install the web console on Linux, Windows, or macOS operating systems and access the web console in a browser. The web console has been tested with Chrome and Firefox. Prerequisites OpenJDK 1.8, OpenJDK 11, Oracle JDK 1.8, or Oracle JDK 11 8 GB RAM macOS: The value of maxproc must be 2048 or greater. Procedure 1. Download the installation archive file from the MTA Download page . 2. Extract the .zip file to a directory of your choice. NOTE If you are installing on a Windows operating system, extract the .zip file to a folder named mta to avoid a Path too long error. The directory is referred to as <MTA_HOME> in this guide. 3. Start the web console: Linux operating system: $ <MTA_HOME>/run_mta.sh Windows operating system: C:\<MTA_HOME>\run_mta.bat 4. Open a browser and navigate to http://localhost:8080/mta-web. Figure 2.1. Welcome Page 5 Migration Toolkit for Applications 5.0 Web Console Guide Figure 2.1. Welcome Page The web console installation creates a default mta user with a default password, password. You can add additional users to the web console. 2.2. INSTALLING THE WEB CONSOLE ON OPENSHIFT CONTAINER PLATFORM You can install the MTA web console on Red Hat OpenShift Container Platform and access the web console in a browser. 2.2.1. Understanding the web console image Red Hat offers containerized images for MTA that are designed for use with OpenShift Container Platform. Using these images developers can quickly and easily manage migration projects and analyze applications. The MTA image installs the following Pods: The Executor Pod runs analyses and generates reports The Web Console + Red Hat Single Sign-on (SSO) Pod provides access to the web console The PostgreSQL Pod stores the project’s configuration and analysis tracking information A separate persistent volume is used for the web console interface and the PostgreSQL Pods. The Executor Pod’s storage is dependent on the template used. The web-template-empty-dir-executor.json is the recommended template. It configures the Executor Pod to use temporary storage on a single machine and has no defined persistent volume.

  • List of NMAP Scripts Use with the Nmap –Script Option
    List of NMAP Scripts Use with the nmap –script option Retrieves information from a listening acarsd daemon. Acarsd decodes ACARS (Aircraft Communication Addressing and Reporting System) data in real time. The information retrieved acarsd-info by this script includes the daemon version, API version, administrator e-mail address and listening frequency. Shows extra information about IPv6 addresses, such as address-info embedded MAC or IPv4 addresses when available. Performs password guessing against Apple Filing Protocol afp-brute (AFP). Attempts to get useful information about files from AFP afp-ls volumes. The output is intended to resemble the output of ls. Detects the Mac OS X AFP directory traversal vulnerability, afp-path-vuln CVE-2010-0533. Shows AFP server information. This information includes the server's hostname, IPv4 and IPv6 addresses, and hardware type afp-serverinfo (for example Macmini or MacBookPro). Shows AFP shares and ACLs. afp-showmount Retrieves the authentication scheme and realm of an AJP service ajp-auth (Apache JServ Protocol) that requires authentication. Performs brute force passwords auditing against the Apache JServ protocol. The Apache JServ Protocol is commonly used by ajp-brute web servers to communicate with back-end Java application server containers. Performs a HEAD or GET request against either the root directory or any optional directory of an Apache JServ Protocol ajp-headers server and returns the server response headers. Discovers which options are supported by the AJP (Apache JServ Protocol) server by sending an OPTIONS request and lists ajp-methods potentially risky methods. ajp-request Requests a URI over the Apache JServ Protocol and displays the result (or stores it in a file).

  • What Good Is a Linux Client?
    Preparing Today for Linux® Tomorrow What Good is a Linux Client? A Linux White Paper Preface Anyone who has followed the progress of Linux the past few years has noted the surprising gains that Linux has made in server operating system market share and “mindshare” against the entrenched opposition, notably Microsoft® Windows NT®, Novell Netware and various varieties of UNIX®. A complete Linux network, of course, would require Linux clients (networked PCs or terminals) as well. Therefore, an important question is, “Is Linux a viable desktop operating system for general business use?” or must we continue to be confined to the Windows world for our non-server needs? And what about laptop support, or a Small Office/Home Office (SOHO) user or home user, who does not need a network server? Is there a place for Linux in a stand-alone environment? These are some of the questions this paper addresses. I must confess that until recently I was merely a bystander watching with curiosity from the sidelines—without any real involvement— the progress Linux has made. So writing this paper not only gave me the excuse to join in on the action, but it also provides you with the perspective of a Linux “newbie” who is attempting to find the applications and utilities needed to create a working system. The conventional wisdom so far is that Linux is not “ready for prime time” as anything but a network operating system. We shall test this notion to see if I can find commercial, shareware and/or freeware programs for Linux to replace the existing applications I currently use with Windows.

    Schumpeterian competition and diseconomies of scope; illustrations from the histories of Microsoft and IBM Timothy Bresnahan Shane Greenstein Rebecca Henderson Working Paper 11-077 Copyright © 2011 by Timothy Bresnahan, Shane Greenstein, Rebecca Henderson Working papers are in draft form. This working paper is distributed for purposes of comment and discussion only. It may not be reproduced without permission of the copyright holder. Copies of working papers are available from the author. Schumpeterian competition and diseconomies of scope; illustrations from the histories of Microsoft and IBM. Timothy Bresnahan, Shane Greenstein, Rebecca Henderson* Abstract: We address a longstanding question about the causes of creative destruction. Dominant incumbent firms, long successful in an existing technology, are often much less successful in new technological eras. This is puzzling, since a cursory analysis would suggest that incumbent firms have the potential to take advantage of economies of scope across new and old lines of business and, if economies of scope are unavailable, to simply reproduce entrant behavior by creating a “firm within a firm.” There are two broad streams of explanation for incumbent failure in these circumstances. One posits that incumbents fear cannibalization in the market place, and so under-invest in the new technology. The second suggests that incumbent firms develop organizational capabilities and cognitive frames that make them slow to “see” new opportunities and that make it difficult to respond effectively once the new opportunity is identified. In this paper we draw on two of the most important historical episodes in the history of the computing industry, the introduction of the PC and of the browser, to develop a third hypothesis.
