Using NAT between the vCenter Server system and ESX hosts

Details

Each time you add an ESX host to vCenter Server, the IP address of vCenter Server is recorded on the ESX host. If the ESX host is behind a NAT and the vCenter Server is on a different network (and thus the address is not accessible due to the NAT), the host disconnects from vCenter Server after about a minute. 

For example, the vCenter Server system might be on the main network (10.10.10.0), and a few of the ESX hosts might be behind a firewall in the 192.168.5.x network. The hosts cannot reach the main network and thus become disconnected from vCenter Server. Continue reading Using NAT between the vCenter Server system and ESX hosts

Open-Mesh Revisited

Well after my first attempts with those little white boxes, along came the OpenWRT-Linux guru of our net to point out that most of the ways i tried to tackle problems are things of the past for OpenWRT.  As a matter of fact i think that most of the problems i am trying to tackle under Linux are me own patchwork around my ignorance to some new developments or ways around things. But hey this is the deal. Attempt and right the wrongs by great collaboration and good friends. So lets say thanx to Vasilis Tsiligiannis for all the help and guidance he provided in rewriting and perfecting the script we needed. Continue reading Open-Mesh Revisited

Open-Mesh! Let the games Begin!

Being so preoccupied with other wi-fi architectures and deployments, I failed to catch up to the meshing Craze. Yes its true that for speedy wifi nets you need the directional antennas, the best and fastest SBCs or X86s, various optimizations and tens of other detains. On the other hand when you move closer to the ground, you different issues. To deliver signal to users you really need something better, more clever than a dozen of WDS devices. The truth is that mesh configs with OLSR and BATMAN really shine in Hotspot conditions and outperform older solutions. Continue reading Open-Mesh! Let the games Begin!

.NET Framework 4 – Microsoft Has done its Miracle Again!

I was putting off an ERP Client update for so many days, up until we found a chance to Hit the upgrade button.

That meant that not only the ERP client was upgraded but also the new blue shiny .net 4 was also downloaded and installed. Thats when it all started.

Most of the Lenovo machines in the net that had windows XP Pro SP3 went completely dead. No network, no responsiveness, sloooooow login on to the domain, up until we had a pile of those machine stuck in a corner for inspection and eventual a reformat with windows 7 (A very long awaited and wanted opportunity :)).

LVM Partition Resizing After Imaging Or VM disk Resize

This is topic that I tend to revisit forget… revisit…. forget…loop.

This is getting printed before we do another log google loop.

Taken from my LVM management notes. I had first used this when I imaged an 80GB drive to a 120GB drive and wanted to make use of the 40GB of free space.
