Oracle 12.1.0.2 works with firewall on Oracle Linux 7
 
08:33
Most Oracle 12c setting up disabled firewall. But we really need firewall to run most of times. This video shows that there is no problem for Oracle 12.1.0.2 to run with firewalld turned on. You can pause the video to see which ports and services are turned on in order to make the Oracle 12c works with firewall on. I did not turn on SELinux though. If you test it out for SELinux, please let me know.

Installing Oracle Linux 7.4
 
12:01
Installing Oracle Linux 7.4 Scott Lynn has announced the release of Oracle Linux 7 Update 4, an updated build of the company's enterprise-class Linux distribution built from the source code for Red Hat Enterprise Linux 7.4 but featuring its own "unbreakable" kernel. This version was announced last month, but it was only yesterday that the installation DVD images appeared on public mirrors. From the release announcement: "Oracle is pleased to announce the general availability of Oracle Linux 7 Update 4 for x86-64 servers. What's new? Enhancements to Oracle Linux 7 included in this update are included for several key areas, including security, support for Cloud and Container environments, and performance. Oracle Linux 7 Update 4 continues to enhance your security stance with several new capabilities. UEFI Secure Boot - a system in Secure Boot mode loads only those boot loaders and kernels that have been signed by Oracle. Oracle has updated the kernel and GRUB 2 packages to sign them with a valid Extended Validation (EV) certificate. The EV certificate has been compiled into the shim binary and has been signed by Microsoft. OpenSSH now uses SHA-2 - by default, the algorithm for public key signatures that is used in this release is SHA-2. Reference: https://distrowatch.com/?newsid=09955

This tutorial will show you how to find potentially vulnerable ports using Zenmap in Kali Linux. Kali linux is a linux distro released specifically designed for penetration testing. Zenmap is a GUI (Graphical User Interface) for a tool called Nmap, Zenmap makes it alot easier to see and use. Once you have found vulnerable ports you can try different exploits on them, which I will go through in later videos. http://heresjaken.com/ Music by R3oath: http://r3oath.bandcamp.com/

JMX: Much More Than Just Application Monitoring
 
55:43
You have probably heard of Java Management Extensions (JMX) as the enabling technology behind JVM profiling tools such as JConsole and VisualVM that are part of JDK 6 and later. But did you know that using JMX, part of the Java SE platform, is a lightweight way to manage any resource (such as hardware, networks, storage, operating systems, middleware, and applications)? In this session, you will learn about • The JMX architecture • Managing a resource in JMX, with a code example • JMX notifications • JMX connectors (RMI for remote clients and WS-Man for Web services clients) • Protocol adapters (HTML and SNMP) • JConsole and VisualVM, the "out of the box" JMX clients for JVM monitoring • Practical applications of JMX in the real world • JMX-enabled Java products" Copyright © 2013 Oracle and/or its affiliates.
