Some solutions like Tomcat accepts connections on port 8080.
But this port is not open by default in Debian Linux servers and can result in the service to fail for the duration of setup.
Currently, we’ll take a appear at how our Help Engineers configure Debian to accept connections in port 8080.
What is port 8080 applied for?
Port 8080 is an option to port 80 and is usually applied as a proxy and caching port. It is also above the properly-identified service port variety (1-1023).
For instance, applications like Apache Tomcat, M2MLogger, and a Internet GUI use port 8080 to connect to world-wide-web solutions.
If net address utilizes port 8080, it call for a default port to override and connect as an alternative of the port 80 ie., the user has to form http://localhost:8080/net.
- localhost ( hostname ) is the machine name or IP address of the host server e.g Glassfish, Tomcat.
- 8080 ( port ) is the address of the port on which the host server is listening for requests.
- net – path pointing to the root of the public folder of your server.
How do I obtain out my port 8080 is opened?
It is easy, you can use netstat command to see if port 8080 is opened.
netstat -aon | findstr "8080"
This command displays all connection, approach Id and listening port.
Now, let’s take a appear at the various approaches and how we open port 8080 in Debian.
Solutions to open port 8080 in Debian
There are various approaches to open port in Debian.
Now, let’s see every one particular of them listed under.
1. Working with iptables
From our encounter in managing servers, we see that iptables is one particular of the most popular strategies to open port in Debian. This demands specific guidelines to let and block targeted traffic in iptables. Any incorrect command can outcome in server unreachable.
That is why, our Help Engineers normally double verify the iptables guidelines just before saving them. And, the iptables command to open port 8080 is,
iptables -I INPUT 1 -i eth0 -p tcp --dport 8080 -j ACCEPT
service iptables save
service iptables restart
To list which ports are opened run the under command
2. Adding port in apache2
Not too long ago one particular of our clients reported us with a trouble to add port 8080 in apache2 exactly where his OS is Debian 4.1.2-25.
So, to repair the trouble we opened apache2/ports.conf file and added the following lines.
NameVirtualHost *:8080 Listen 8080
And also in apache2/websites-readily available/default file added the under line.
Then, restarted apache2 service and verified if the port is opened by operating the command
3. Working with UFW
Similarly, yet another selection to open port 8080 is making use of UFW (Uncomplicated Firewall).
This is a user-friendly front-finish for managing iptables firewall guidelines much easier.
With UFW for an application like Tomcat to open port 8080, we execute the measures like this.
ufw let 8080/tcp ufw status
The output will appear like this.
Status: active To Action From -- ------ ---- [ 1] 22/tcp Let IN Anyplace [ 2] 80/tcp Let IN Anyplace [ 3] 8080/tcp Let IN Anyplace
4. Working with FirewallD
In addition, FirewallD is a default firewall management tool that manages the system’s iptables guidelines.
Opening a port 8080 in firewalld is pretty easy, you need to have to run the command and reload the service as shown under.
firewall-cmd --prmanent --add-port=8080/tcp firewall-cmd --reload
To list the ports that are opened run the under command.

To open port 8080 in Debian, we can use any approaches like iptables, ufw, firewalld, and so forth. Currently, we saw how our Help Engineers opened “Debian open port 8080”.
