Restoring a Sun system using JumpStart technology

Post date: April 13, 2005, 05:04 Category: Installing Views: 4858 Comments
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.

Making Web Browsing Easy For The Tiny Screen

Post date: August 9, 2005, 19:08 Category: Network Views: 3641 Comments
Tutorial quote: An avalanche of content will soon appear in the palm of your hand.

Tiny screens are showing up everywhere in PDAs and cell phones. Many are equipped with some form of network device and a browser, so it's not hard to see what's coming down the pike.

Late model PDAs, like my HP iPAQ 3715 no longer suffer from insufficient computing power, lack of memory or having to rely on pricey external 802.11b cards. The little machine is quick to boot up and can handle many daily business functions.

Even though it runs a version of Internet Explorer, jumping onto an access point and browsing web pages is fast and useful.

In this edition, I'll share my observations on things you might consider when converting LAMP (Linux, Apache, MySQL, PHP) applications or web pages, for use on the tiny screen. I'll approach the issues from an iPAQ user perspective and focus on convenience and making the user's life easy.

How To Install Qmailtoaster (CentOS 5.3)

Post date: June 19, 2009, 10:06 Category: Installing Views: 8476 Comments
Tutorial quote: Qmailtoaster is a project that aims to make the installation of Qmail onto RPM based systems a snap. All of the packages are distributed in source RPMs so building the packages for your particular distro and architecture is as easy as running a script or a simple command for each package. The RPMs have all of the needed and commonly asked for patches included so you can have a mail server up and running in about an hour. When it's all complete, you'll have a full Qmail mail server installation ready for just about anything. I personally run Qmailtoaster servers for other companies and ISPs who have tens of thousands of users on their systems.

Drupal 6 Hosting With nginx And PHP-FastCGI On Ubuntu 9.10

Post date: April 8, 2010, 11:04 Category: Installing Views: 5277 Comments
Tutorial quote: Drupal is a great CMS but is a bit hefty when you host it on bargain-basement shared hosting, and virtual private servers are great but memory-constrained at the low-end. Apache can be a big offender when it comes to resource usage, so a nice alternative is nginx, a fast, light-weight and efficient http server that supports PHP via PHP-FastCGI. So this is a pretty slick setup for hosting Drupal, and I've taken a few different howtos and forum posts to put together this guide, which should have all you need in one stop, including a working URL rewrite config.

OpenVZ On Debian Etch For Webservers

Post date: December 26, 2006, 21:12 Category: System Views: 4131 Comments
Tutorial quote: Virtualization is a good practice for servers, since it makes things more secure, scalable, replacable, and replicable, all this at the cost of little added complexity. This guide was written during an install of a Supermicro machine with two dual-core opterons (64-bit), two identical disks (for RAID) and a load of memory. Why OpenVZ and not XEN or the recent KVM kernel module? Well, XEN is not very stable for 64-bit architectures (yet), and it comes with quite a bit of overhead (every VM runs its own kernel) due to its complexity. KVM is very simple but restricts you to run a kernel as one process, so the VM cannot benefit from multi core systems.

Installing Solaris using JumpStart technology on an Intel laptop

Post date: April 13, 2005, 05:04 Category: Installing Views: 4699 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.

How To Harden PHP5 With Suhosin On Fedora 7

Post date: July 25, 2007, 23:07 Category: Security Views: 4203 Comments
Tutorial quote: This tutorial shows how to harden PHP5 with Suhosin on a Fedora 7 server. From the Suhosin project page: "Suhosin is an advanced protection system for PHP installations that was designed to protect servers and users from known and unknown flaws in PHP applications and the PHP core. Suhosin comes in two independent parts, that can be used separately or in combination. The first part is a small patch against the PHP core, that implements a few low-level protections against bufferoverflows or format string vulnerabilities and the second part is a powerful PHP extension that implements all the other protections."
