 To undo this change:
 `timedatectl set-local-rtc 0 --adjust-system-clock`

2. Add a (command) directory to the '$PATH' in Ubuntu

Edit `.bashrc` in your home directory and add the following line: 

`export PATH="/path/to/dir:$PATH"`

You will need to source your '.bashrc' or logout/login (or restart the terminal) for the changes to take effect. To source your '.bashrc', simply type 

`source ~/.bashrc`

3.  Install "proxychains"
 `apt-get install proxychains`

Edit:   `/etc/proxychains.conf`               (`chmod...` etc.)
Add:  `socks5 127.0.0.1 1080`

Note that: there is a DNS issue in "tsocks"

Use the following script to switch ports:
`re='^[0-9]{4}$'
if [ "$#" -eq  "0" ]
  then
    echo "Error: No arguments supplied"
else
    if ! [[ $1 =~ $re ]] ; then
       echo "Error: argument '$1' is illegal!"
    else sudo sed -i -r 's/(127.0.0.1 )([0-9]{4})/\1'"$1"'/g' /etc/proxychains.conf
    fi
fi`
