VMware remote support esxi

Useful command, working remotley 


ESXi 4.x, 5.x and 6.0
To power on a virtual machine from the command line:

<pre>
List the inventory ID of the virtual machine with the command:

vim-cmd vmsvc/getallvms |grep <vm name>

Note: The first column of the output shows the vmid.

Check the power state of the virtual machine with the command:

vim-cmd vmsvc/power.getstate <vmid>


Power-on the virtual machine with the command:

vim-cmd vmsvc/power.on <vmid>

Open a console session where the esxcli tool is available, either in the ESXi Shell, the vSphere Management Assistant (vMA), or the location where the vSphere Command-Line Interface (vCLI) is installed.

Get a list of running virtual machines, identified by World ID, UUID, Display Name, and path to the .vmx configuration file by running this command:

esxcli vm process list

Power off one of the virtual machines from the list using this command:

esxcli vm process kill --type= [soft,hard,force] --world-id= WorldNumber

Notes:
Three power-off methods are available. Soft is the most graceful, hard performs an immediate shutdown, and force should be used as a last resort.	
Alternate power off command syntax is: esxcli vm process kill -t [ soft,hard,force] -w WorldNumber
Repeat Step 2 and validate that the virtual machine is no longer running.

For ESXi 4.1:
Get a list of running virtual machines, identified by World ID, UUID, Display Name, and path to the .vmx configuration file by running this command:

esxcli vms vm list

Power off one of the virtual machines from the list by running this command:

esxcli vms vm kill --type= [soft,hard,force] --world-id= WorldNumber

Soft Ether VPN Notes

To diable vpnserver from calling home, i.e. stop all the chit-chat for nat traversal and just use it as a normal vpnserver.


Step 1 dissable DDNS change the config file DDNS section to read:

declare DDnsClient { bool Disabled true }

Step 2 dissable UDP acceleration I did this from the config file by setting:

bool DisableUdpAcceleration true

Step 3, Disable Nat Traversal In the config file change the following setting.

bool DisableNatTraversal true

Step 4, turn off keep alive. This is via the GUI on the server encryption and network button.

Step 5, turn of auto update check. Again this is via the GUI on the server encryption and network button.


Having done the above (thanks to dnobori, for the ones I missed) and restarted the server, I know don't see any outbound / unexpected traffic.

Virtualization

Brother 32bit drivers on 64bit linux

Debian example: 

apt-get install lib32z1 lib32ncurses5
optional: apt-get install cups
mkdir -p /var/spool/lpd
dpkg -i --force-all mfc5890cnlpr-1.1.2-2a.i386.deb 
dpkg -i --force-all mfc5890cncupswrapper-1.1.2-2a.i386.deb

Openvz / proxmox

Adding nat iptables modules to container, example:

vzctl set 115 --iptables "iptable_nat iptable_filter iptable_mangle ip_conntrack ipt_conntrack ipt_REDIRECT ipt_REJECT ipt_multiport ipt_helper ipt_LOG ipt_state" --save

partition disk.

Command Prompt with administrative rights

diskpart, (if you have already used the drive letters suggested below choose a different one and substitute it in the commands.)

List the available disks by running "list disk" and you should see your usb device.

Select your USB drive by typing "select disk #" and hit Enter. For example, “select disk 1”.

Clean the partitions on the disk by typing "clean" and hit Enter.

Now create the boot partition by running the following command: 

create partition primary size=350
Now create the OS partition by running the following command to create a partition taking up all remaining space:

create partition primary
The boot partition needs to be formatted, configured and assigned a drive letter, run the following commands:

select partition 1
format fs=fat32 quick
active
assign letter=b

(if the b drive letter is already in use on your PC, substitute a different letter and replace b with your letter
throughout the rest of this guide)

The same must be done for the OS partition, run the following different commands:

select partition 2
format fs=ntfs quick
assign letter=o

(if the o drive letter is already in use on your PC, substitute a different letter and replace o with
your letter throughout the rest of this guide)
Exit Diskpart by typing Exit.

Extract wim file.

(from the windows 8/8.1 install media) sources directory.

dism /apply-image /imagefile:c:\path\install.wim /index:1 /applydir:o:\

add drivers (optional)

dism /image:u:\ /add-driver /driver:*BootCamp Directory*\Drivers /recurse

make bootable

o:\windows\system32\bcdboot o:\windows /f ALL /s b:

Certificates

Check key / cert are mached (also csr )

checking the modulus and the public exponent portions in the key and the Certificate must match.

But since the public exponent is usually 65537 and it's bothering comparing long modulus you can use the following approach: 

$ openssl x509 -noout -modulus -in server.crt | openssl md5
$ openssl rsa -noout -modulus -in server.key | openssl md5

And then compare these really shorter numbers.

if I want to check to which key or certificate a particular CSR belongs you can compute 

$ openssl req -noout -modulus -in server.csr | openssl md5

This simple circuit was built on vero board in a matter of 40 mins. Not pretty but it was made of mostly second hand bits, infact two of the resistors bellow where from a PC board from a 1980's computer!
