17 Aug 2009 Search Wikipedia using the command line

This post describes how you can search Wikipedia from the command line using a DNS tool like nslookup in Windows or dig in linux.
Handy if you don’t wan’t to open a Internet browser to do a simple Wikipedia query.

Windows
This is how it’s done in Windows

  1. Choose Start -> Run
  2. Write “cmd” and press OK
  3. Write “nslookup” and press ENTER
  4. Write “set type=txt” and press ENTER
  5. Write <topic>.wp.dg.cx and press ENTER

Using linux
This is how it’s done from a console window in linux

# dig +short txt search_keyword.wp.dg.cx

Example

# dig +short txt oslo.wp.dg.cx
"(formerly Christiania) is the capital and largest city in Norway. Metropolitan Oslo or the Greater Oslo Region makes up the third largest urban area in Scandinavia after Metropolitan Stockholm and Metropolitan Copenhagen. http://en.wikipedia.org/wiki/Oslo"

14 Aug 2009 Getting VMware vSphere Client to run on Windows 7 RTM

This post describes how you can get your VMware vSphere Client version 4 running on a 32-bit Windows 7 (RTM) installation until VMware makes an update to fix this Microsoft .Net problem. Be aware that this method of getting the client to run is not recommended in a production environment since you are running the client in development mode.

First you need to edit the VpxClient.exe.config file located in your C:\Program Files\Vmware\Infrastructure\Virtual Infrastructure Client\Launcher folder and make it look like the code below

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.net>
<connectionManagement>
<clear/>
<add address="*" maxconnection="8" />
</connectionManagement>
</system.net>
<appSettings>
<add key = "protocolports" value = "https:443"/>
</appSettings>
<runtime>
<developmentMode developerInstallation="true"/>
</runtime>
</configuration>

Next we have to ensure that you we the .Net system.dll from a non Windows 7 machine.

It’s possible to download the config file and the DLL filer from here.

Place the modified config file in your C:\Program Files\Vmware\Infrastructure\Virtual Infrastructure Client\Launcher folder.

Then we create a new folder called Lib in the folder noted above and place the downloaded DLL file in the folder.

windows-7-environment-settings
windows-7-environment-settings-2Reboot your PC and VMware vSphere Client should now work without any error messages.

Edit your system properties and create a new ‘Environment Variable” Name it “Devpath” with the value of C:\Program Files\VMware\Infrastructure\Virtual Infrastructure Client\Launcher\Lib. You can locate these variables under Control Panel –> System and Security –> System –> Advanced system settings

This post came to life after reading this thread on the VMware Communties discussion forum. The thread also describes how to make VMware vSphere Client to work on 64-bit Windows 7 but I’m not going to describe that in this post.

07 Aug 2009 Suspend a VMware Workstation host from command line

This post gives a short description of how to suspend a VMware Workstation 6.5.x guest/VM on a Ubuntu 9.04 Workstation but it shouldn’t be any problem to follow it on other linux distributions. Lately I’ve experienced that one of my VMware Workstation host lock up and my mouse cursor stops responding. The keyboard doesn’t let me switch applications (Alt+Tab) because the Tab-key doesn’t respond. The solution to my problem was to suspend the virtual machine from the console.

  1. First you have to switch to a console by pressing Ctrl+Alt+F1 – This lets you login to a console.
  2. Suspend the virtual machine by issuing the following command from the console
    # vmrun suspend /path/to/the/vmx-file/vmxfile.vmx

Switch back to your graphical desktop by pressing Ctrl+Alt+F7. You will now see that the suspend indicator is hard at work suspending the virtual machine that is causing problems. When the host has been suspended you can shutdown VMware Workstation as you normally do.

To make sure that VMware haven’t got any processes that are defunct stop and start the VMware daemon.

Note:
Remember to shut down or suspend all virtual machines before issuing the following commands from the console to avoid losing data

Stopping the VMware daemon

# /etc/init.d/vmware stop

Stopping VMware services:
   Virtual machine communication interface                             done
   Virtual machine monitor                                             done
   Blocking file system                                                done

Starting the VMware daemon

# /etc/init.d/vmware start

Starting VMware services:
   Virtual machine monitor                                             done
   Virtual machine communication interface                             done
   Blocking file system                                                done
   Virtual ethernet                                                    done
   Shared Memory Available                                             done

Start VMware as you normally do and resume the host. The host should now work without any problems.

The vmrun command gives you other options as well like list, start, stop, reset and upgradevm, but I won’t describe the use of these in this post.
