Opening a Port on Ubuntu Using UFW (Uncomplicated Firewall)

-

To open a specific port (in this case, 9040) on Ubuntu, we can use ufw (Uncomplicated Firewall), which is a user-friendly firewall tool in Ubuntu and other Linux.

For example, follow these steps to open port 9040 TCP :


1. Check UFW Status

First, check if UFW is enabled by running the following command in the terminal:


 jason@GU502DU:~$ sudo ufw status
 [sudo] password for jason:
 Status: active
 
 To                         Action      From
 --                         ------      ----
 22/tcp                     ALLOW       Anywhere
 9200/tcp                   ALLOW       Anywhere
 3000/tcp                   ALLOW       Anywhere
 22/tcp (v6)                ALLOW       Anywhere (v6)
 9200/tcp (v6)              ALLOW       Anywhere (v6)
 3000/tcp (v6)              ALLOW       Anywhere (v6)
 

If UFW is not active, you can enable it with:


 jason@GU502DU:~$ sudo ufw enable

 Command may disrupt existing ssh connections. Proceed with operation (y|n)? y

 Firewall is active and enabled on system startup


2. Open Port 9040

To open port 9040, use the following command:


 jason@GU502DU:~$ sudo ufw allow 9040/tcp

 Rule added
 Rule added (v6)

This command allows inbound connections on port 9040 using the TCP protocol.


3. Verify the Rules

To confirm the changes, check the current firewall rules with ufw status:


 jason@GU502DU:~$ sudo ufw status
 Status: active
 
 To                         Action      From
 --                         ------      ----
 9040/tcp                   ALLOW       Anywhere
 9040/tcp (v6)              ALLOW       Anywhere (v6)

In the output of this command, you should see that port 9040 is open.


Important Notes

  • Using Cloud Services : If you are using cloud services like AWS, Azure, or Google Cloud, you may also need to open the port in the network security groups or firewall settings provided by the cloud service provider.

How to Set Up Vaultwarden (Bitwarden) on Synology NAS (Best Free Alternative to LastPass)

-
Image
Have you ever felt overwhelmed managing passwords for all your websites? I used to use the same password across multiple sites , which wasn’t secure. To manage them better, I started using LastPass for years. However, in 2019, they changed their pricing policy — now it’s free only for one device for 30 days, and you have to pay to use it across multiple devices . If you're looking for a powerful and free password manager, Vaultwarden is one of the best alternatives to LastPass. What is Vaultwarden? Vaultwarden (formerly known as Bitwarden_RS) is a lightweight, open-source implementation of the Bitwarden server API written in Rust . It is fully compatible with official Bitwarden clients and is ideal for low-resource environments. Example: On a Synology DS916+, Vaultwarden uses 0% CPU and only 64MB of memory while running. My Setup NAS Model : Synology DS916+ DSM Version : DSM 7.1-42661 Update 1 Docker Image : vaultwarden/server Ins...
