Cyber terrorism – a must watch video from CBS news

A video depicting cyber terrorism threat was publish under 60 minutes on CBS news. The only message it sends out loud and clear is Cyber terrorism threat has become real out of theories.

Developing countries that started exposing their critical systems to computer networks (connected to Internet) have to care about cyber terrorism right from beginning than spending billions to fix the issue which possibly they might not able to afford.

Below is a video that I have embedded from CBS news site. (NOTE: I have embedded this video as it allows anyone to embed it on their webpage)

VMware Virtual to Physical (V2P) migration

We all know that it is possible to migrate from Physical machine to Virtual Machine (P2V migration). (If someone is not aware of it then look at a free tool from VMware called vCenter Convertor).  That is what most of us used to do to consolidate data center from physical to virtual environment.

However, recently, I had a requirement to migrate Virtual machine to Physical machine (V2P migration). And while googling, I found a whitepaper from VMware Virtual Machine to Physical Machine Migration.

I was impressed by what I found and planning to test it if time permits. If someone has gone through Virtual Machine to Physical Machine Migration (V2P migration) then please share your experience in comments below.

Blogger customized templates are broken

This is a note for the readers of www.TechSutram.com

Today morning, it is observed that there are misalignments of different columns on this blog. I have tried to restore my backup template but it seems that customized templates on blogger are broken. As this blog is hosted on blogger platform and relies on blogger templates solely for its layout, there is nothing much I can do to rectify this issue.

Interestingly, all layouts and alignments are perfectly visible from Mozilla Firefox browser and misalignment issue lies only with Microsoft Internet Explorer. It seems that blogger team is already aware of this issue and they are investigating this issue http://knownissues.blogspot.com/search/label/outstanding.  

If you are using Microsoft Internet Explorer to browse this blog and you are able to see this blog properly then let me know in the comments section below.

OpenSUSE 11.1 and Intel PRO/Wireless 3945ABG not working

I had a strange problem when Wireless card on one of my laptops with OpenSuse Linux 11.1 was replaced. 

Originally, all network connections were under control of KDE Network Manger (knetworkmanager).  However, after replacing old wireless card with PRO/Wireless 3945ABG, KDE network manager stopped working. It was able to detect my wireless connection, however, it couldn’t able to connect to my Wireless ESSID. I tried rebooting my OpenSuse Linux 11.1  laptop still it was unable to connect.

Eventually I was able to resolve this issue. What I did was not very special but it did work. I put my network under traditional network using YAST. YAST prompted me to install few required packages (only one in my case). After that I configured my wireless connection using traditional network using YAST and I was able to connect my Wireless ESSID successfully. Once I got my wireless connection working, I put my network back under Network manager again. This procedure has resolved my issue and I was able to connect my wireless connection using KDE network manager in OpenSuse Linux 11.1

This procedure has worked for me. I am not sure if it is going to work for everyone else depending on their unique configuration. However, it might help to troubleshoot this issue with their PRO/Wireless 3945ABG card.

Mounting NFS share hangs on VMware ESX server

I just happened to face very trivial issue while mounting NFS share on VMware ESX box. I did verify NFS exports on NFS server and NFS service was indeed running on NFS server.

Also verified that “nfsClient” service is enabled in ESX firewall using esxcfg-firewall CLI.

[root@esx35 root]# esxcfg-firewall --enableService  nfsClient

Still I couldn’t able to mount NFS share on VMware ESX and mount command was hanged or stuck.

[root@esx35 root]# mount –t nfs nfs-server:/share /mnt/share

.

.

.

^C

After bit of troubleshooting, it was found that “portmap” service was down by default. So after enabling “portmap” service, mount CLI succeeded in mounting NFS share.

[root@esx35 root]# /etc/init.d/portmap status
portmap is stopped
[root@esx35 root]# /etc/init.d/portmap restart
Stopping portmapper:                                       [FAILED]
Starting portmapper:                                        [  OK  ][root@esx35 root]#mount –t nfs nfs-server:/share /mnt/share[root@esx35 root]#echo $?
