...OPEN SOURCE SOFTWARE What are reasons for business to use open source software? With the current economy difficulties, companies are trying to find areas in their businesses where they can save money. Many companies are having no choice but to let people go. Some businesses try to avoid lay-offs and instead are looking in other areas to save money. One of the areas is, of course, the IT department; software application acquisition is an area that might lead to a big money savings. Even in financially difficulties times, businesses want or need to improve their application environment. Sometimes it might even be necessary to invest in the IT infrastructure for long-term savings, which may result in the company not needing to close their doors. But many business owners or CEO’s will question if open source software is ready for business. This research paper intends to answer this question. The best reason to use open source software in a business environment is cost savings. This gives the business freedom to use software and change the source code in other words, modify how the software application is used, as it is needed. Open source removes the need for dependence on single vendor solutions and it provides very high quality applications and very good support. To understand open source software it is important to know what open source is, and what the meaning of open source software is. This research paper will also show where open source came from; the history of open...

...B2: Features and Characteristics of SUSE Linux Enterprise Server 12 (3.12) 1. System Rollback System malfunctioning and failures due to misconfiguration of system parameters and accidentally removal of critical system components such as applications can cause imaginable consequences. Therefore, recovery capability is one of the most concerned aspect. The system rollback feature in SUSE Linux Enterprise Server 12 (3.12) give organization’s servers better resiliency and availability by taking snapshot of system when it is running under healthy condition. When system failure occurs and require recovery action, system administrator can easily reboot the system from the snapshot which has been integrated into system bootloader. 2. Live Patching Capability...

...SELinux SELinux was developed by the United States National Security Agency. It was then released for open source development on December 22, 2000 and was merged into the main Linux kernel version 2.6.0-test3 on August 8, 2003. SELinux was designed to change the access control protocols for Linux users, to make them more secure and computer resources and applications less likely to be exploited. Prior to the development of SELinux, systems used a form of DAC, Discretionary Access Control. In this set up, placed all clients into three categories: user, group, and other. If an application or file were "exploited," it would allow the current user to access the file(s) or application at the highest permission allow, the owner of the file, or user. SELinux introduced two new ways to allow permissions to be determined by the client computer. The first of these is MAC, Mandatory Access Control. This new protocol introduce the principle of least privilege, which simply allows programs to use what resources they need to do the task at hand, and nothing else. An example from an article I found online: "if you have a program that responds to socket requests but doesn't need to access the file system, then that program should be able to listen on a given socket but not have access to the file system." The second protocol is RBAC, Role-based Access Control. In this protocol, "permissions are provided based on roles that are granted by the security system." From what I read of roles...

...Linux Security Technologies There are many ways to have internet access these days. Coffee shops, libraries, airports and even public buses have free wireless access. With all these free accesses to the World Wide Web, there is also many potential ways for hackers to potentially get your personal information and use it for their gain. There are many ways to combat this situation by using several security measures with Linux programming, which the majority of the software is free. Some of those security technologies are SELinux, TCP Wrappers, IPtables and Chroot Jail to name a few. SELinux is a security enhancement to Linux which allows users and administrators more control over access control. Access can be constrained on such variables as which users and applications can access which resources. Was developed by the NSA in December of 2000. These resources may take the form of files. Standard Linux access controls, such as file modes (-rwxr-xr-x) are modifiable by the user and the applications which the user runs. Conversely, SELinux access controls are determined by a policy loaded on the system which may not be changed by careless users or misbehaving applications. SELinux also adds finer granularity to access controls. Instead of only being able to specify who can read, write or execute a file, for example, SELinux lets you specify who can unlink, append only, move a file and so on. SELinux allows you to specify access to many resources other than files as well, such...

...Installing Cobbler Introduction This post will show you step by step installation of Cobbler, please comment if you think anything’s is missing as you know nothing is perfect, so my blog This topic focus on CentOS/RHEL/Fedora, if everything goes well here you should be able to build client servers without any manual work using PXE boot. Server setup. For the cobbler server basic requirement is you need two NIC cards if you want to use it for DHCP as well. Why do i need two NIC cards because it allow client servers to initially boot up in the private network where Cobbler will handle the installation. Since Cobbler utilizes DHCP and TFTP, making these services listen on a Private network will ensure that they don’t interfere with any other DHCP or TFTP server on the Public network. Once the installation has finished, the client can be moved to the Public network. Installation media You can use any media you want. You can burn iso to DVD of CentOS 5 or 6 or Fedora. Network selection. For the Network Configuration, I renamed System eth0 and System eth1 to Public andPrivate respectively. I configured each NIC with static information and made sure to check theConnect Automatically checkbox for each — otherwise NetworkManager will not bring the NICs up. Package Selection For this section either you can rely on kickstart file which will have all packages listed in a tab called %packages or you can have minimal install like “Server”.
