If you've just upgraded your linux distribution and you get the following error message when trying to start a VM using Vmware workstation 14 player
“not enough physical memory available to start this VM”
Do the following to patch your Vmware workstation player to work with the latest Linux Kernel
This is sometimes required after a Kernel upgrade and the built in VMware player models update doesn't work.
simply uninstalling and reinstalling vmwareplayer makes it usable again.
"Consciousness determines existence"
"Nothing exists in the physical world unless a conscious mind observes it"
and "What has been seen cannot be unseen"
The human brain is a perfect quantum computer, and your consciousness is information stored at the quantum level. Where particle matter is physically entangled with other particles in the universe.(possibly even the multiverse) It is therefore quite plausible that your consciousness can exist after death.
After the death of the body, quantum information carried by consciousness merges with our universe and can exist infinitely in it. It is plausible that your consciousness can migrate to another universe or to another place in this one Instantly, much faster than the speed of light.
Quantum Mechanics is needed to explain the phenomenon of consciousness.
Scientists claim to have found a possible carrier of consciousness. These elements are located inside neuronal microtubules. These microtubules have been attributed with the simple role of providing support as well as a transport mechanism to quantum elements inside living cells. Based on their structure, these microtubules are perfect to act as the transport medium for quantum particles inside the brain. That is likely due to the fact that they are capable of maintaining quantum states for a long time, meaning they can perform a role inside a quantum computer. similar to that of fibre optic networks that carry data between computers. consciousness resides at the quantum level ,The entire body is a conduit and a collaborator with consciousness as a feedback loop.
Watch the below two short videos explaining the double slit experiment before continuing. (you will find them fascinating)
Double slit experiment explained:
second video explaining and illustrating the double slit experiment:
Quantum physics suggests that our observation of the universe is related to the awareness that an electron appears to show in the wave/particle duality (double slit experiment).
We see the world and the universe from our point of reference. We are the monitoring equipment in the double slit experiment. When seen through our eyes, the universe follows Einsteins wave like behaviour, however our eyes as an instrument are only capable of receiving reflections of light in its wave like state and everything we observe follows strictly the laws of nature and relativity. Our presence and observation capability is paramount in how the universe is perceived. However when we are not present, IE we Die. our reality ceases to exist and without an observer the universe which is made up of particles is in a quantum superposition state, as there is no point of reference. The light waves do not have an instrument to measure or see them. The monitoring equipment is switched off. Light is made up of entangled photons and exists as energy in a particle based multiverse in a quantum superposition state. Your consciousness therefore must exist for the universe to continue to exist and therefore your consciousness can be transported anywhere in the universe or multiverse instantaneously. When you have lost your point of reference, IE your Body , eyes, ears etc.
When you die your consciousness is Quantized.
Now watch the following short video before continuing.
Our universe is not only limited to the three dimensions. In fact, new theories hypothesise that there are multiple dimensions. (there could be an unlimited amount) Many of the natural phenomena happening within our universe transcend our known three dimensions. Therefore, we should not assume that the mechanisms of operation of the brain and consciousness are imprisoned within the confines of our three dimensional universe.
Watch the following video..
Watch the following documentary:
Quantum Entanglement.
The idea of quantum entanglement is that two particles can be intimately associated to one another even if they are separated by billions of light-years of space. A change brought about in one particle will have an effect on the other one. And amazingly these changes can occur instantaneously! This theory is completely incompatible with the known theory of Albert Einstein , specifically the theory that information cannot travel faster than the speed of light. But it opens up huge theoretical possibilities for interstellar space travel and exploration, teleportation and even a better understanding of the multi verse.
"If you are not Astonished by Quantum mechanics, then you have not understood it "
Niels Bohr
Pay attention to the teleportation part of the following video at the 18:27 mark
In Einstein's theory of relativity time is relative to your position in space. And the faster you travel towards the speed of light, time slows down for you compared to when you where not in motion, as demonstrated in the
However you the observer will not notice the slow down in time, as space time is always constant and relative to you. Time has continued to be exactly the same from your point of reference. IE in your reality.
But since two different states of time now exists. IE the two different clocks in the Hafele Keating experiment display different times. What has changed? The point of observation has changed. Understand that these are two different realities. Reality is 100% subjective and only exists to its observer. Reality cannot exist independently on it's own.
Space time according to Einsteins theory is a Smooth Continuum. eg light is described as a wave and its speed is constant in all directions, from any observers view. This in itself is incompatible with the theory of relativity because the speed of any moving object is always relative to the observer.
in Quantum mechanics Space and time is Quantized, meaning no relativity exists, but everything is made up of particles that are interconnected, and the mere observation of the particles disrupts their quantum state.
Scientists have teleported particles using particle entanglement. The quantum state of particle A is transmitted from position one to position two between two entangled particles. Once the quantum state of particle A is rebuilt in position two, particle A is then destroyed from position one.
So in theory if every single particle in your body can be entangled, copied and rebuilt instantaneously to a position a billion light years away. This will include your memories and your consciousness which remember are simply information stored at the quantum level.
What then happens if Particle A in position one is not destroyed. Then you would be existing in two places at the same time! and would have two different points of reference. two different observation points and two separate realities.
Which is nearly impossible to comprehend since which reality would you be conscience of? Einstein's theory of relativity simply does not allow for this extraordinary, astonishing possibility. Einsteins theory of relativity needs to have something to be relative to, there must be at least one reality for relativity to work. But Reality can not exist independently. It always needs a single point of reference, hence without reality there can be no relativity. The two aren't mutually exclusive.
"Nothing exists in the universe unless a live, conscious mind observes it" Quantum mechanics does.not have this delema. sub atomic particles (Photons) exist without being observed. , and the multi world possibility now not only becomes probable, but even obvious.
Every living things reality is different. Eg an Ant's reality is completely different to yours, A tree to an Ant is not the same tree that it is to you. A more advanced race might see more to a tree than what we see. A tree may give off vibrations that we do not have the instruments to receive and interpret them with, as we in comparison are limited to the functions of our primitive eyes. But an advanced race could easily have an eye that is better and more advanced than ours, with many more functions, that can receive and make sense of these vibrations. When we let go of our reality IE when we die, it is at that moment that our consciousness is Quantized, and in its quantum state and only whilst it is not being observed, it is capable of being in multiple places at the same time. It is capable of travelling billions of light years in an instant, It is capable of travelling through obstacles, it is capable of all this and more. Your consciousness on steroids. your consciousness now one with the singular cosmic consciousness. You see, if there was no Cosmic consciousness , our universe would not exist.
The same way that the individual cells in your body collectively make up your consciousness. you will one day be part of the collective cosmic consciousness. rather than produced by the brain, consciousness may be a fundamental force of the universe, like gravity or mass. In this way, consciousness came into being when the universe began, and exists everywhere and in everything.
consciousness exists in the cosmic ether at the quantum level, outside the brain, and that the function of the brain may be to ‘pick up’ consciousness, like a radio receiver, and then to ‘channel’ it into our individual organism.
since we’re all individual beings enclosed in our bodies, and the primary aim of our lives is to sustain our own well-being. It makes no sense for us to put the well-being of others before our own, or to go out of our way to help strangers, or members of other species. But if there is a cosmic consciousness , then in a sense it’s something we all share, or participate in. It’s therefore possible for us to empathise with other people, to experience their own sufferings as if they are our own, and to feel a desire to alleviate them. In a sense, other people’s sufferings are our own.

Fedora/CentOS7 / RHEL 7 are completely systemd based, So on these versions of Linux we need to use systemd commands to disable firewalld and enable iptables
Disable Firewalld Service.
# systemctl mask firewalld
Stop Firewalld Service.
# systemctl stop firewalld
Install iptables service related packages.
# yum -y install iptables-services
Make sure service starts at boot:
# systemctl enable iptables
If you do not want ip6tables, You can skip following command
# systemctl enable ip6tables
start the iptables services.
# systemctl start iptables
If you do not want ip6tables, You can skip following command.
# systemctl start ip6tables
Firewalld Service is now disabled, You can use iptables.

When you search in Vim the results are highlighted
if the highlighting colour is wrong you cannot read the text.
There are two sets of default colour maps: One for a light and another one for a dark background.
If you have a black background, use the following command to get a better colour map for syntax highlighting:
:set background=dark
Likewise if you have a light background you would want to use the following command to get a better colour scheme for the highlighter. :set background=light
These commands can either be run inside of vim by going into command mode and entering them.
or you can add them to your .vimrc file
Below are a couple of examples on how you can use dig. These are common examples and include queries such as mail exchange lookup, address record lookup, reverse dns lookup, etc.
you can always add the '+short' option at the end of any dig command to keep the output manageable:
eg dig www.example.com +short
Perform a Basic DNS Dig
This is simply going to tell us what the IP address is for the domain www.example.com. The output will be an IP address which will be something like 1.2.3.4.
dig www.example.com
Reverse DNS Dig
Perform a reverse DNS dig lookup. This will translate an IP address into its domain name. The output will be a domain name such as www.example.com.
dig -x 1.2.3.4
Dig MX Record Lookup
An MX (Mail Exchange) record tells us that the record is a domain name that is responsible for accepting email. The below command will tell us what domain name the mail record below is pointing as well as the priority of the mail records. . The output will be the domain name the record points to such as mail.example.com, which tells us that the mx record example.com resolves to mail.example.com.
dig -t MX example.com
Show the TXT or SPF records
dig example.com txt
Directly Query A DNS Server
By default the dns query will resolve off of your own dns server (which is usually the dns server of your ISP or local server), however we can manually specify the dns server we want to query by adding @ns1.example.com to the dns dig command.
dig @ns1.example.com www.somedomain.com
Directly Query the TXT records of a specific name server dig @ns1.example.com www.somedomain.com txt
Show the Name servers of a domain
Here's how to query for a list of nameservers for a given domain,
dig example.com ns
dig traceroute information
If you like the traceroute command, you can do something similar with dig to follow DNS nameservers, like this, using the dig example.com +trace
A null, also known as Blackhole, is a routing table entry that discards a matching packet without sending it further. It is mainly used for preventing/ blocking an unwanted IP to attack your system. It drops the IP using IPtables. for instance, if you want to block an IP address 192.168.0.1, you can write the command:
# ip route add blackhole 192.168.0.1/32
your system will now drop all packets coming from 192.168.0.1
If we have two network interfaces, eth0 and eth1 and we want it to be shown in a single bond as bond0, we need to first create a config file with the name bond0. The network configuration in Linux stores files in etc/sysconfig/network-scripts/ directory.
The work parameters must be set as follows:
#vi /etc/sysconfig/network-scripts/bond0
DEVICE=bond0 IPADDR=192.168.1.20 NETWORK=192.168.1.0 NETMASK=255.255.255.0 USERCTL=no BOOTPROTO=none ONBOOT=yes
The IP address must be replaced with your actual setup.
Open eth0 and eth1 configuration files
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
# vi /etc/sysconfig/network-scripts/ifcfg-eth1
Modify the parameters as follows: DEVICE=eth0 USERCTL=no ONBOOT=yes MASTER=bond0 SLAVE=yes BOOTPROTO=none DEVICE=eth1 USERCTL=no ONBOOT=yes MASTER=bond0 SLAVE=yes BOOTPROTO=none
Save and close the file.
Now load the bond driver/module when the channel bonding interface is brought up. The kernel configuration files are also modified using # vi /etc/modprobe.conf
Add these lines : alias bond0 bonding options bond0 mode=balance-alb miimon=100
Test configuration using these two steps:
Firstly, load the bonding module:
# modprobe bonding
Restart the network to see bond0 interface:
# service network restart
Both Nic's should now be working as one
