[RESOLVED] Opening PORTS in Ubuntu

How do you open a Port in XUBuntu?

Based on this post: https://help.ubuntu.com/8.04/serverg.../firewall.html

The default firewall for Ubuntu is ufw.

You can open a port in ufw with the below command

Code:

---

sudo ufw allow 22

---

Or to allow it only from a specific IP

Code:

---

sudo ufw allow proto tcp from 192.168.0.2 to any port 22

---

Although they also mention you have to enable it, so maybe the firewall isn't on by default. If that is the case, you will need to deal with whatever you're using for an external firewall.

If you want a GUI to configure ufw, try installing gufw.
