Portop is a fast, interactive network port monitor for Linux — available in your terminal, browser, and Cockpit.
Portop gives you an htop-style view of TCP and UDP sockets and the processes behind them, helping you quickly answer a simple question:
What's really using your ports?
Terminal UI
Run portop for a lightweight, keyboard-driven TUI with real-time network and process information.
Features include:
Web Dashboard
Run:
portop --web
to launch a local web dashboard with live TCP/UDP socket and process information.
The dashboard provides:
By default, the web server listens only on the local loopback interface.
Optional authentication can be enabled with:
portop --web --web-auth
Portop also supports custom bind addresses and HTTPS using your own TLS certificate and key, making it possible to securely access the dashboard from another machine.
Cockpit integration
Portop can also be installed as a Cockpit add-on.
Once installed, open:
Tools → Ports (portop)
to get the same live port and process inspection directly from the Cockpit web interface.
The integration uses Cockpit's own bridge and user permissions, so no additional Portop daemon or network service is required.
Three ways to use Portop
Terminal: portop
Browser: portop --web
Cockpit: Tools → Ports (portop)
Portop is designed for developers, system administrators, DevOps engineers and Linux users who need a fast way to understand network activity and identify the processes behind it.
Lightweight, open source and released under the MIT License.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap can be installed from the command line on openSUSE Leap 15.x and Tumbleweed.
You need first add the snappy repository from the terminal. Choose the appropriate command depending on your installed openSUSE flavor.
Tumbleweed:
sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Tumbleweed snappy
Leap 15.x:
sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Leap_15.6 snappy
If needed, Swap out openSUSE_Leap_15. for, openSUSE_Leap_16.0 if you’re using a different version of openSUSE.
With the repository added, import its GPG key:
sudo zypper --gpg-auto-import-keys refresh
Finally, upgrade the package cache to include the new snappy repository:
sudo zypper dup --from snappy
Snap can now be installed with the following:
sudo zypper install snapd
You then need to either reboot, logout/login or source /etc/profile to have /snap/bin added to PATH.
Additionally, enable and start both the snapd and the snapd.apparmor services with the following commands:
sudo systemctl enable --now snapd
sudo systemctl enable --now snapd.apparmor
To install Portop, simply use the following command:
sudo snap install portop
Browse and find snaps from the convenience of your desktop using the snap store snap.
