Installing Solaris using JumpStart technology on an Intel laptop

Post date: April 13, 2005, 05:04 Category: Installing Views: 3796 Comments
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.

Key-Based SSH Logins With PuTTY

Post date: December 10, 2006, 20:12 Category: Security Views: 3484 Comments
Tutorial quote: This guide describes how to generate and use a private/public key pair to log in to a remote system with SSH using PuTTY. PuTTY is an SSH client that is available for Windows and Linux (although it is more common on Windows systems). Using key-based SSH logins, you can disable the normal username/password login procedure which means that only people with a valid private/public key pair can log in. That way, there is no way for brute-force attacks to be successful, so your system is more secure.

Building a Virtual Cluster with Xen

Post date: September 28, 2006, 04:09 Category: Emulation Views: 7512 Comments
Tutorial quote: It is a common practice to have development and test servers for each production server, so that you can experiment with changes without the fear of breaking anything important, but this is usually not feasible with clusters. So how do you try that new version of your favorite program before committing it to the production cluster? A cheap and convenient possibility is to build a virtual cluster.

Thanks to the Xen virtual machine monitor, you can create a number of virtual machines, all running simultaneously in your computer, install different operating systems in them, or just different configurations, and connect them via (virtual) network cards. Xen is a terrific tool for building virtual Beowulf clusters. It can prove useful when learning or teaching about clusters or for testing new features/software without the fear of causing major damage to an existing cluster.
