#### 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 Ubuntu 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

If you’re running [Ubuntu 16.04 LTS (Xenial Xerus)](https://www.ubuntu.com/) or later, including [Ubuntu 18.04 LTS (Bionic Beaver)](https://www.ubuntu.com/desktop/features) and [Ubuntu 20.04 LTS (Focal Fossa)](https://wiki.ubuntu.com/FocalFossa/ReleaseNotes), you don’t need to do anything. Snap is already installed and ready to go.

For versions of Ubuntu between [14.04 LTS (Trusty Tahr)](https://wiki.ubuntu.com/TrustyTahr/ReleaseNotes) and [15.10 (Wily Werewolf)](https://wiki.ubuntu.com/WilyWerewolf/ReleaseNotes), as well as Ubuntu flavours that don’t include *snap* by default, *snap* can be installed from the Ubuntu Software Centre by searching for *snapd*.

Alternatively, snapd can be installed from the command line:

```
sudo apt update
sudo apt install snapd
```

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