#### Find listening ports and the processes behind them

See what's listening. PortWatch is a focused Linux desktop utility for
finding TCP and UDP listening ports and the processes behind them.

Search by port, process, service, address or protocol. Inspect projects,
related listeners, containers and systemd services when Linux permissions allow.
Request graceful process termination with confirmation. Run the CLI with
snap run portwatch.portwatch-cli (supports search and --json).

Connect network-observe and system-observe for listener/process visibility.
Connect process-control to enable process termination. The app displays the
required connection commands. Desktop shortcuts require manual setup.
Container/service stop and restart and opening host project folders or
terminals are unavailable in this strictly confined test package.

## Enable snaps on CentOS and install PortWatch

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](https://snapcraft.io/store), an app store with an audience of millions.

### Enable snapd

Snap is available for [CentOS 7.6+](https://snapcraft.io/install/portwatch/centos), and Red Hat Enterprise Linux 7.6+, from the [Extra Packages for Enterprise Linux](https://fedoraproject.org/wiki/EPEL) (EPEL) repository. The EPEL repository can be added to your system with the following command:

```
sudo yum install epel-release
```

Snap can now be installed as follows:

```
sudo yum install snapd
```

Once installed, the *systemd* unit that manages the main snap communication socket needs to be enabled:

```
sudo systemctl enable --now snapd.socket
```

To enable *classic* snap support, enter the following to create a symbolic link between `/var/lib/snapd/snap` and `/snap`:

```
sudo ln -s /var/lib/snapd/snap /snap
```

Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.

### Install PortWatch

To install PortWatch, simply use the following command:

```
sudo snap install portwatch --edge
```
