Ubuntu Server 16.04.05 USB Installation Requesting CD-ROM

How to fix the Insert CD-ROM Notification when you are not installing from CD-ROM

This fix is simple.  You are running the Ubuntu server installation from a USB drive. 

You get the dialog box asking for the CD-ROM…Simply remove the USB drive (that has the installation media on it) from the port that it is plugged into. 

Move it to another USB Port….and the installation will find the device, think it is a CD-ROM and the install will continue.

Insert the following into the file#

#!/bin/sh

nvidia-smi -pm 1
nvidia-smi -acp 0
nvidia-smi -pl 300
sleep 2

Installing Teamviewer 13 on Ubuntu 18.04

How to Install Teamviewer on a Headless Server

Teamviewer Installation has changed in the recent version, and the prior directions will not work.  You will continue to receive an error after you insert the password saying there was a connectivity time out.  The new way to install teamviewer is as follows:

Login 

sudo bash

add-apt-repository “deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) universe”

apt-get update

apt-get install gdebi-core

mkdir /home/miner/teamviewer

cd /home/miner/teamviewer

wget https://download.teamviewer.com/download/linux/teamviewer-host_amd64.deb

dpkg -i teamviewer-host_amd64.deb

It will fail and that’s ok because we will fix it here

apt-get -f install

y

After it installs then type

teamviewer info

Take a note of your Teamviewer ID, you will need it later

teamviewer passwd YOURPASSWORDHERE

Now open teamviewer on another computer that you are logged into.  Add the computer using the menu “Add Computer“, enter in your Teamviewer ID and the Password you used in YOURPASSWORDHERE, and you can now connect

Testing and Securing Against a WPS Attack

How To Check If You Are Vulnerable, and Then Secure Your Network

First you will want to download and install reaver, wash and airmon-ng.  If you are running Kali or Parrot, it is already there.  You will also need a wireless adapter that is capable of packet injection.  Assuming you have those, you will want to open a terminal and run the following

sudo bash

ifconfig

Note which adapter is your wireless card, that is capable of packet injection.  For the rest of this, lets assume it is wlan0.

airmon-ng check kill

wash -i wlan0

Note the BSSID of your Wireless Access Point / Wireless Router

reaver -i wlan0 -b MacAddressOfMyRouter -vv 

After some time my router/ap gave up the ghost.  It showed my WPS pin.  I am running a wireless router with a Broadcom chip, which is susceptible.

To fix this, I had to log into my wireless router, navigate to the WPS settings, and I changed it from Enabled to Disabled.  I saved the settings, and voila…I haven’t been able to crack the WPS pin again

Phone Number Privacy Apps – 2018

  • Phones

Private Numbers Apps for Your Cell Phone

The need to keep your number private increases by the day.  Websites, and Applications constantly request your cell phone number to verify who you are, when you sign up, but how do you know you can trust these sites?  Who has access to your cell phone number now?  The lack of privacy is growing by the day.  I don’t know about you, but I do not want my cell number all over craigslist every time I contact a potential seller for something.

The solution to the problem is easy, keep your cell number private and use a temporary number to Text, or Call from.  You can receive temporary numbers to get the access you need and still remain private.  Below you will find a list of applications that will help you on this quest, and a bit of info about each.

Hushed:
– No phone number required during Sign-Up
– No email required during Sign-Up
– You can purchase a number for a few dollars through the App Store, instead of putting your info into some third party site
– Allows for a secure passcode when you open the app each time

TextFree:
– Requires an email address to join, however this can be a throwaway address from any domain such as gmail
– You will have a free number to use for text messaging or receiving text messages, and you can use this to sign up for other apps on the list if you so choose.

Flyp:
– Verification using a phone number that the app can text. You could use a TextFree number to receive this verification.
– App requires you to buy a package immediately during signup, so this is where my research ended

Unlisted:
– Name and Email address required during Sign-Up. You can use a free email service to receive the verification.
– App requires you to buy a package immediately to receive a phone number, so this is where I stopped as well.

Burner:
– Requires a number to Sign-Up. You CAN NOT use a TextFree number for this verification, it gives you an error about an Unsupported Carrier. So it will require your actual cell phone number sign up, and defeats the purpose of why we want the app.

Sideline:
– Requires a number when signing up. This can be a TextFree number.
– 7-Day Free Trial is available as well. So you can use this service, just remember to cancel it after the 7 days is up, unless you want the number for a longer period of time.

Choose which works best for you, or a combination of two apps.  I liked the ability to get a free TextFree Number to receive the verifications from the other apps, and would suggest starting with that.
