#3 – VMWare ESXi – Enable ssh Access
Posted by mru in VMWare, VMWare ESXi, vSphere on October 30, 2009
To access the ESXi command line you have to do some configuration on the ESXi local console. This is the procedure I used to get it up and running on my “Lab” box.
- alt-F1 (Note: As pointed out below, you will not see your typing on this screen, just trust us, it is there).
- unsupported
- root pw
- vi /etc/inetd.conf
- delete the “#” from ssh
- services.sh restart OR ps aux |grep inetd (getting the PID) and then kill -HUP PID

#2 – VMWare ESXi – Boot from USB stick
Posted by mru in VMWare, VMWare ESXi, vSphere on October 28, 2009
So, for completeness, here I will show you how to boot and run ESXi from an USB stick. A short description…
#1 – VMWare ESXi – Installation from USB stick
Posted by mru in VMWare, VMWare ESXi on October 22, 2009
You can find a lot of descriptions in the internet for how to install ESXi on an USB stick and how to boot from it.
Many hardware manufacturers deliver their server systems without cd drives so you got to know how to install ESXi via USB stick. I’ve found a short description (http://www.squishnet.com/?p=17), tested it and it works fine for me.

#1 – vSphere 4 – Configuration maximums
Posted by mru in VMWare ESX, VMWare ESXi, vSphere on July 15, 2009
Before you decide to implement the vSphere 4.0 virtualization solution from VMWare you have to know about the configuration maximums and limitations that this solution will come with. First with this knowledge you will be able to answer the question “Could I transfer my expensive physical infrastructure into a virtualized and, over years, cheaper solution? Is my physical infrastructure ‘virtualizable’?”.
Linux Unix KnowHow/ Tools for Admins
Posted by fkr in linux / unix on July 12, 2009
Some useful tool’s and their switches to work with for admins
Useful Switches within ‘ls’:
Unix fileattributes have 3 different types of time-flag
- - Accesstime (atime)
- - Creationtime (ctime)
- - Modificationtime (mtime)
those can be displayed with the switch –time=(atime|ctime|mtime).
Recommended while using –time is -l for long display. Otherwise the
time is not displayed.
Useful Switches within ‘df’:
To get a human readable formatted output, use switch -h. Same works for the du command
#5 – command line reference – vimsh – updated
Posted by mru in VMWare ESX, VMWare Infrastructure on June 22, 2009
Update: added download link at the end of this post.
With esxcfg and also vmware-cmd you’ve got only limited possibilities to configure your ESX server from command line or automated per script. So, if you wanna go further and do deeper system configurations, DON’T EDIT esx.cfg MANUALLY (!), use ‘vimsh’ command line tool. Vimsh got’s it’s own shell environment where you can do a step by step configuration interactively or alternative you could run a script for automated system configuration (batch processing). There are no official whitepapers from VMWare which explain the usage. Since ESX 3.5 vimsh got it’s own wrapper called vmware-vim-cmd. This enables vimsh to do configuration without the need of starting or exiting shell environments for command execution.
In compare to esxcfg and vmware-cmd, vimsh (vmware-vim-cmd) offers a very large functional range.
#4 – command line reference – vmware-cmd
Posted by mru in VMWare ESX, VMWare Infrastructure on June 15, 2009
vmware-cmd is also a very useful commandline tool. It enables you to control the behavior of virtual machines. For example it is possible to register, stop or start virtual machines from commandline or per script or to get and set specific values. vmware-cmd could be used either from COS (/usr/bin/vmware-cmd) or per VMWare Scripting API (%program files%\VMWare\VMWare VmPerl Scripting API\vmware-cmd).
#3 – command line reference – vmkfstools
Posted by mru in VMWare ESX, VMWare Infrastructure on May 8, 2009
A powerful tool to manage all issues regarding storage is ‘vmkfstools’. With this file system management tool you are able to manage vmfs as well as virtual harddisks.
Usage: vmkfstools [Options] [Partition/Device/Path]
