Get full control over your ESXi Server

How to get command line access and SSH running, just need a nice OS tool to manage all these ESXi instances!

Also here are the commands to get SNMP enabled via RCLI.

C:\Program Files (x86)\VMware\VMware VI Remote CLI\bin>perl vicfg-snmp.pl --server yourserverip -c public -p 5567 -t trapserverip@162/public
Enter username: root
Enter password:
Changing udp port to 5567...
Changing community list to: public...
Changing notification(trap) targets list to:

C:\Program Files (x86)\VMware\VMware VI Remote CLI\bin>perl vicfg-snmp.pl --server
yourserverip -E
Enter username: root
Enter password:
Enabling agent...

C:\Program Files (x86)\VMware\VMware VI Remote CLI\bin>perl vicfg-snmp.pl --server
yourserverip -s
Enter username: root
Enter password:
Current SNMP agent settings:
Enabled : 1
UDP port : 5567

Communities :

Notification targets :

C:\Program Files (x86)\VMware\VMware VI Remote CLI\bin>perl vicfg-snmp.pl --server
yourserverip -T
Enter username: root
Enter password:
Sending test nofication(trap) to all configured targets...
Complete. Check with each target to see if trap was received.

ESXi 3.5 does ship with the ability to run SSH, but this is disabled by default (and is not supported). If you just need to access the console of ESXi, then you only need to perform steps 1 - 3.

1) At the console of the ESXi host, press ALT-F1 to access the console window.
2) Enter unsupported in the console and then press Enter. You will not see the text you type in.
3) If you typed in unsupported correctly, you will see the Tech Support Mode warning and a password prompt. Enter the password for the root login.
4) You should then see the prompt of ~ #. Edit the file inetd.conf (enter the command vi /etc/inetd.conf).
5) Find the line that begins with #ssh and remove the #. Then save the file. If you're new to using vi, then move the cursor down to #ssh line and then press the x key. Type in :wq to save the file and exit vi. If you make a mistake, you can press the ESC key and then type :q! to quit vi without saving the file.
6) Run ps | grep inetd to determine the process ID for the inetd process. The output of the command will be something like 1299 1299 busybox inetd, and the process ID is 1299. Then run kill -HUP (kill -HUP 1299 in this example) and you'll then be able to access the host via SSH.

SNMP configuration for ESXi

Silverstripe CMS

Homepage: www.SilverStripe.com/
Latest Version: 2.0.2b
View Demo: http://demo.silverstripe.com/


SilverStripe is a free software / open source content management system (CMS) for creating and managing websites through a simple web interface. It has many advanced features. These features include an MVC framework, XHTML compliance, multiple ways of organising navigation through folksonomy, a flexible data object model, multiple templates per page, a separate "draft site" and "published site through staging content, asset management , image resizing, versioning and rollback, SEF URLs with meta-data. SilverStripe is designed for UTF-8 support including internationalisation of character sets. It also deploys content through RSS and full text search, including searching of PDF's and Word documents.

SilverStripe 2.x coding began in late 2005, as an overhaul to take advantage of object orientation and other features of PHP5, and to allow Firefox/Macintosh compatibility, which had been difficult as SilverStripe 1.x predated Firefox.

SilverStripe is released under the terms of the BSD Licence.


How to Create Your Own Bootable ESXi USB Stick

HOW TO Create your own bootable ESX 3i usb stick


  • 1 GB USB flash drive
  • WinImage
  • 7Zip

Of course you can use your favourite tools and larger USB flash drives, but 1 GB is enough space for the boot image.
Perform the following steps to create a bootable ESX Server 3i USB flash drive:

  1. Download ESX Server 3i Installable ISO
  2. Extract INSTALL.TGZ from the root directory of the ISO image using an 7Zip
  3. Extract /usr/lib/vmware/installer/VMware-VMvisor-big-3.5.0-xxxxx.i386.dd.bz2 from INSTALL.TGZ using 7Zip
  4. Extract VMware-VMvisor-big-3.5.0-xxxxx.i386.dd from VMware-VMvisor-big-3.5.0-xxxxx.i386.dd.bz2 using 7Zip
  5. Attach the USB flash drive and make sure you no longer need the data on it
  6. Use WinImage to transfer VMware-VMvisor-big-3.5.0-xxxxx.i386.dd to the USB flash drive
    1. Disk->Restore Virtual Hard Disk image on physical drive…
    2. Select the USB flash drive (Warning: If you select the wrong disk you will lose data!)
    3. Select the image file VMware-VMvisor-big-3.5.0-xxxxx.i386.dd
    4. Confirm the warning message
    5. Wait for the transfer to complete
  7. Unplug the USB flash drive (Warning: If you forget to unplug the flash drive from the PC you might lose the data on your hard drives the next time you boot!)
  8. Attach the USB flash drive to the machine you want to boot (Warning: If ESX Server 3i recognizes local drives, you might lose the data on it, so make sure you don´t need it anymore or unplug all hard drives!)
  9. Turn the machine on and make sure the USB flash drive is selected as boot device
  10. Watch ESX Server 3i boot
  11. Configure
  12. Enjoy!

Platespin, handy for VMWare, PowerRecon Inventory edition, could be useful


Unfortunately it doesn't install on a test Server 2003 standard machine. Server just created a virtual folder under the default website and the client just throws a continual stream of 401 results. :(
