I want to install LAMP in Ubuntu. I have installed Apache. After the command sudo ufw allow in "Apache Full" it shows "unable to resolve host". How can I solve this?

To resolvethe host just add it to /etc/hosts, like at the example:

According to the @Rinzwind's comment, I think, port 80/443 must be opened in the Windows firewall. Here is a video instruction about it.


If you have a router and you want your web server to be accessible from outside, don’t forget to add some port forwarding. Something like that:

Port Forwarding


I will leave here and these few tips about UFW configuration on native Ubuntu:

To allow external access to Apache through UFW, you need to use:

sudo ufw allow http
sudo ufw allow https

To enable tcp protocol only use:

sudo ufw allow http/tcp
sudo ufw allow https/tcp

You can use and the port number directly:

sudo ufw allow 80/tcp
sudo ufw allow 443/tcp

For some services (like "SSH" or "Webnin", which by default uses web interface at port 10000) you can add little security by using of limit rule instead of allow. This will limit the number of login attempts per certain time for these ports:

sudo ufw limit ssh/tcp
sudo ufw limit 10000/tcp

Just in case you can reload the "rules table":

sudo ufw reload

    Sorry but he asked about bash in WINDOWS. How do you see this answering 1. that there is no GUI in windows (so you also need an X-server). and 2. that you need windows related software (like ktpass).
