DNS Correction for the Staging Server
Safer alternative
This is a safer alternative for accessing the staging server, if you only need that access in a browser.
sudo apt-get install firejail firejail --dns=10.241.189.1 firefox
Run After Connecting
sudo cp /etc/resolv.conf /etc/resolv.conf.bak
echo "nameserver 10.241.189.1" | sudo tee /etc/resolv.conf
Run After Disconnecting
sudo rm /etc/resolv.conf
sudo mv /etc/resolv.conf.bak /etc/resolv.conf
