To Install Cockpit Web Console On Debian 11.3

Introduction:

The Cockpit is a web console with an easy-to-use web-based interface that allows you to carry out administrative tasks on your servers.

tcp   LISTEN 0      4096               *:9090             *:*    users:(("cockpit-tls",pid=13826,fd=3),("systemd",pid=1,fd=277)) ino:70806 sk:16 cgroup:/system.slice/cockpit.socket v6only:0 <->

Step 10: Now allow the cockpit port 9090 in the firewall by using the below command

[root@linuxhelp ~]# sudo ufw allow 9090

Step 11: Open the Cockpit web console in your web browser by using the below URL’s:

Locally: https://localhost:9090
Remotely with the server’s hostname: https://example.com:9090
Remotely with the server’s IP address: https://192.168.0.10:9090
