#### Cisco TRex realistic traffic generator

TRex is an open source, low cost, stateful and stateless traffic generator
fuelled by DPDK. This snap packages the TRex server, console and Python
automation client from the upstream trex-core source.

The server runs in af\_packet mode on kernel interfaces, without hugepages
or NIC driver binding. DPDK PCI mode is not supported under strict
confinement.

**Setup**

```
 sudo snap connect trex-generator:network-control
 sudo snap connect trex-generator:hardware-observe
 sudo snap connect trex-generator:process-control
 sudo snap connect trex-generator:system-observe
```

**Configuration**

Configuration files, scripts and their output live in
/var/snap/trex-generator/common. Select the server configuration with
`sudo snap set trex-generator config=<path relative to that directory>`
(default `trex_cfg.yaml`), or pass `--cfg <absolute path>`.

**Commands**

* `trex-generator.t-rex-64`: TRex server
* `trex-generator.console`: interactive console
* `trex-generator.python`: Python with the TRex automation client

## Enable snaps on openSUSE and install trex-generator

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 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
```

### Install trex-generator
