If you need to get a view on authentication attemps on an ESXi and to order by IP address and attemps counts:

1grep -Eo "Connection from [^ ]* " $(ls -rt /var/log/auth.*) | awk '{print $NF}' | sort | uniq -c | sort -nr

And you will get something like:

1156 172.16.25.23
216 172.16.25.32
31 172.16.52.2

In this article, we will see how to create, commit, revert-to virtual machine snapshots from ESXi command line. We will also talk about the very useful "linked clones" that are related to the snapshot feature.

Prerequisites

You only need to have a running VM on the ESXi and to know its Vmid:

1    $ vim-cmd …

Now that we've seen how to create a nested-ESXi on virtualbox, we may need to have some content in order to test commands of procedures.

Local datastore

Disk creation

To create a local datastore, you'll have to add a new virtual disk to your nested ESXi:

First step is to create a SATA disk controller:

For testing cases it could be very useful to host a nested (= virtualized) VMware ESXi on your desk or laptop machine. For my own needs, I had to install an ESXi on virtualbox. Here is my tutorial.

Installation

Prerequisites

In order to install an ESXi 5.5 you'll have to provide:

• 64-bit x86 processor with at least 2 …
