Solaris Restoring a Sun system using JumpStart technology
Post date: April 13, 2005, 01:04 Category: Installing Views: 96
Tutorial quote: If a server crash and the file systems are corrupted or totally destroyed, then the only way to recover the data is to restore from backups. If it is only user data that is corrupted, the task is in general simple, but if the system disk fails, then there is a little bit more work involved in order to to recover the system. This article explains how to backup Sun systems using ufsrestore over NFS, and how to use Sun's JumpStart technology to restore Sun servers and workstations over the network.
Solaris Installing Solaris using JumpStart technology on an Intel laptop
Post date: April 13, 2005, 01:04 Category: Installing Views: 97
Tutorial quote: An interesting use of Solaris 8 on a PC laptop is for use with the JumpStart technology. It has never been so easy to install, re-install, or restore a server before.

As I am as a contractor, I am more on the road than in my own office, so I need a laptop, and preferably with Solaris installed, as I am focusing on Sun's products and applications.

Through the years, I have discovered that one of the most common scenarios is that a client needs a server installed, either because they just bought it, or need it re-installed, or recovered.

This article covers how to save time when installing servers, using the JumpStart technology on a laptop with Solaris for Intel.
FreeBSD Bluetooth Security Review, Part 1
Post date: April 29, 2005, 20:04 Category: Security Views: 66
Tutorial quote: Bluetooth (BT) wireless technology provides an easy way for a wide range of devices to communicate with each other and connect to the Internet without the need for wires, cables and connectors. The technology seams to be very interesting and beneficial, yet it can also be a high threat for the privacy and security of Bluetooth users.

Unix+clones Xen Disk I/O benchmarking: NetBSD dom0 vs Linux dom0
Post date: April 21, 2005, 06:04 Category: Benchmarks Views: 107
Tutorial quote: Xen is a relatively new technology to enable several virtual machines (domU) to run on one computer. The purpose of this article is to determine what operating system (NetBSD or Linux) should be selected as domain 0 (dom0) operating system to get the best performance when running several CPU and disk intensive virtual machines at the same time.
Unix+clones Considerations for the system architect: Performance
Post date: April 20, 2005, 06:04 Category: Miscellaneous Views: 86
Tutorial quote: For many developers and engineers, performance is often an afterthought. But when a product functions as designed and has proven stability and the right feature mix, success in the marketplace often depends upon performance. Architectural decisions define the ultimate feasible performance of any product. In this article, learn how performance-monitoring technology initially developed for mainframes can help you improve your own code's performance.
Fedora+Core The IPv6 Internet: Connect Today with Linux
Post date: April 12, 2005, 23:04 Category: Network Views: 86
Tutorial quote: IPv6 is a key technology and a long-term solution to build scalable, reliable, manageable, secure, and high-performance IP networks. In this article, I demonstrated how to configure a Linux machine running Fedora Core 1 to support IPv6 and connect it to the IPv6 Internet using the Freenet6 service.
Linux iptables: The Linux Firewall Administration Program
Post date: November 29, 2005, 15:11 Category: Network Views: 86
Tutorial quote: This chapter covers the iptables firewall administration program used to build a Netfilter firewall. For those of you who are familiar with or accustomed to the older ipfwadm and ipchains programs used with the IPFW technology, iptables will look very similar to those programs. However, it is much more feature-rich and flexible, and it is very different on subtle levels.
Solaris How to Perform System Boot and Shutdown Procedures for Solaris 10
Post date: February 6, 2006, 02:02 Category: System Views: 43
Tutorial quote: System startup requires an understanding of the hardware and the operating system functions that are required to bring the system to a running state. This chapter discusses the operations that the system must perform from the time you power on the system until you receive a system logon prompt. In addition, it covers the steps required to properly shut down a system. After reading this chapter, you’ll understand how to boot the system from the OpenBoot programmable read-only memory (PROM) and what operations must take place to start up the kernel and Unix system processes.
Unix+clones How to Set Up a Jabber Server
Post date: April 12, 2005, 12:04 Category: Software Views: 37
Tutorial quote: Unless you have been living under a rock for the past few years, you must have heard about instant messaging and how it has changed the world of communications over the Internet. According to http://www.webopedia.com, Instant Messaging (IM) is a service that alerts users when their friends or colleagues are on line and allows them to communicate in real time through private online chat areas. Two of the most popular IM services are AOL Instant Messenger (AIM) and MSN Messenger. Unfortunately, most of the publicly available servers use proprietary protocols that only allow you to communicate with users on the same system. These systems are not compatible with each other and can't be accessed from other clients.

Jabber is an open source implementation of the IM server that aims to change this. It uses streaming XML protocols that are free, open, and public. These protocols have been formalized by the Internet Engineering Task Force (IETF) as the approved instant messaging and presence technology under the name of XMPP. The first Jabber technologies were developed in 1998 by Jeremie Miller and is now used on thousands of servers world-wide to enable millions of users to communicate with each other.

The biggest advantage of the Jabber server when compared with commercial IM servers is that, since it is open source, anyone can run a Jabber server and it can be restricted to a specific community like a company work force or a group of friends. In this article, I will document the steps I took to set up a Jabber server and how I managed to overcome the difficulties I faced. Hopefully this will make it easier for you to set up your own Jabber server.
