Puppet install is pretty straightforward
this article is based on these versions
puppet-2.6.6-3.fc15.noarch
puppet-server-2.6.6-3.fc15.noarch
on the master server install puppet-server
1 | yum install puppet-server |
and on the clients

1. Click on host then Configuration tab
2. Right click on the datastore for the VM you want to clone and then > Browse Datastore
or
you can login to the ESXi server and copy the volume from the datastore manually
It should be in /vmfs/volumes/”DataStore Name”/”Virtual Machine Name”
1 | cp -p -r -f "Virtual Machine Name" "New Virtual Machine Name" |
3. rename the virtual disks using vmkfstools
1 | vmkfstools -E "src".vmdk "new".vmdk |
4. Rename the vmx and nvram file to reflect the new virtual machine name
5. Right click the vmx file and > Add to Inventory
6. Power ON the virtual machine
These are the different ways you can encrypt file in linux, we will use openssl and gnupg’s file encryption and decryption process.
Symmetric encryption
as the name says symmetric encryption uses the same pair of key to encrypt and decrypt a file which is OK if you are not bothered too much about the security of the location of pass-phrase.
from the command prompt type
1 | openssl des3 -salt -in file -pass file:pass -out file.encrypt |
were file:pass is the location of the passphrase file or you can remove this option and enter the passphrase manually.
to decrypt the encrypted file, use
1 | openssl des3 -d -salt -in file.encrypt -out file |
if you have the gnupg program installed, you can encrypt the file using:

in case if you dont want plesk to be the primary nameserver for your domains, and if your architecture has a centralized DNS server, then you can push zones from plesk to your primary nameserver

FootPrinting is an art of gathering target information. Its, just like knowing about your enemy before you try to attack. A successful attacker must harvest a wealth of information to execute a focussed and surgical attack. This enables an attacker to create a complete profile of an organization’s security posture and this is achieved by using a combination of tools and techniques.

Scanning helps one to know what services are running on a machine. This will
show the open ports on which services are listening for connections.
First we will determine whether the target machine is alive or not. This can
be done by sending a icmp echo request packet to the server. The server would
respond with a icmp echo reply showing that it’s alive. The process to
do this on a range of hosts or ipaddresses is known as ping sweep .

A martian data packet is a network data packet that has an impossible source or destination IP, such as a packet that claims to have come from the broadcast address, 255.255.255.255. Another example of a martian packet would be if you received a packet from 192.168.0.1 through your networks external gateway.

Normally, when people think of using nmap, they assume it’s used to conduct some sort of nefarious network reconnaissance in preparation for an attack. But as with all powerful tools, nmap can be made to wear a white hat, as it’s useful for far more than breaking into networks. Continue Reading…
