OpenSolaris – Desktop Experience – Part 1

Installation

Few days back I installed OpenSolaris 2008.11 on my aging IBM R50e Thinkpad. My previous experience with OpenSolaris Solaris Express builds were not that great from desktop point of view. Primary problem being no support for the Intel Pro Wireless adapter IPW2200B/G and the multimedia support. This time LFY distributed a live CD of OpenSolaris 2008.11, so I thought of trying my hands on it. Immediately after booting I was impressed with the desktop which came up and reminded me of my first Ubuntu experience. A quick glance at the top-right panel and I saw two network interfaces iwi0 and iprb0. Hmmm, so it picked up both my network interfaces.

The overall interface looked good and quite similar to Ubuntu, so it was familiar to me.

Balancing Traffic Across Data Centres Using LVS

Posted on May 1, 2009 by Ajitabh

The real servers and the load balancers may be interconnected by either a high speed LAN or by a geographically dispersed WAN.”

The zonecfg command is used to configure the zone. We can add and remove a resource from the solaris zone using zonecfg. Any change to zonecfg needs a reboot, but sometimes it is a requirement to dynamically add new resources to the zone without rebooting the zone. Also, we need to make sure that the addition of new resources to the zone are persistent across reboots.

Posted on April 1, 2009 by Ajitabh

I recently bought a Compaq Presario V3000 laptop after my IBM Thinkpad gave up on me. Since this is a 64-bit laptop I thought it will be a nice opportunity to jump into the 64-bit desktop experience.
