wireshark

linuxserver/wireshark

Wireshark is the world’s foremost and widely-used network protocol analyzer. It lets you see what’s happening on your network at a microscopic level and is the de facto (and often de jure) standard across many commercial and non-profit enterprises, government agencies, and educational institutions. Wireshark development thrives thanks to the volunteer contributions of networking experts around the globe and is the continuation of a project started by Gerald Combs in 1998.

Supported Architectures

We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.

Simply pulling lscr.io/linuxserver/wireshark:latest should retrieve the correct image for your arch, but you can also pull specific arch images via tags.

The architectures supported by this image are:

Architecture	Available	Tag
x86-64	✅	amd64-<version tag>
arm64	✅	arm64v8-<version tag>
armhf	❌

Application Setup

In order to dump from an interface you will need to pass NET_ADMIN at a minimum, optionally you can use host networking to capture from your host level device or specify a Docker network you want to capture from.

The application can be accessed at:

Options in all KasmVNC based GUI containers

This container is based on Docker Baseimage KasmVNC which means there are additional environment variables and run configurations to enable or disable specific functionality.

Optional environment variables

Variable	Description
CUSTOM_PORT	Internal port the container listens on for http if it needs to be swapped from the default 3000.
CUSTOM_HTTPS_PORT	Internal port the container listens on for https if it needs to be swapped from the default 3001.
CUSTOM_USER	HTTP Basic auth username, abc is default.
PASSWORD	HTTP Basic auth password, abc is default. If unset there will be no auth
SUBFOLDER	Subfolder for the application if running a subfolder reverse proxy, need both slashes IE `/subfolder/`
TITLE	The page title displayed on the web browser, default "KasmVNC Client".
FM_HOME	This is the home directory (landing) for the file manager, default "/config".
START_DOCKER	If set to false a container with privilege will not automatically start the DinD Docker setup.
DRINODE	If mounting in /dev/dri for DRI3 GPU Acceleration allows you to specify the device to use IE `/dev/dri/renderD128`

Optional run configurations

Variable	Description
`--privileged`	Will start a Docker in Docker (DinD) setup inside the container to use docker in an isolated environment. For increased performance mount the Docker directory inside the container to the host IE `-v /home/user/docker-data:/var/lib/docker`.
`-v /var/run/docker.sock:/var/run/docker.sock`	Mount in the host level Docker socket to either interact with it via CLI or use Docker enabled applications.
`--device /dev/dri:/dev/dri`	Mount a GPU into the container, this can be used in conjunction with the `DRINODE` environment variable to leverage a host video card for GPU accelerated appplications. Only Open Source drivers are supported IE (Intel,AMDGPU,Radeon,ATI,Nouveau)

Lossless mode

This container is capable of delivering a true lossless image at a high framerate to your web browser by changing the Stream Quality preset to "Lossless", more information here. In order to use this mode from a non localhost endpoint the HTTPS port on 3001 needs to be used. If using a reverse proxy to port 3000 specific headers will need to be set as outlined here.

Usage

To help you get started creating a container from this image you can either use docker-compose or the docker cli.

docker-compose (recommended, click here for more info)

---
version: "2.1"
services:
  wireshark:
    image: lscr.io/linuxserver/wireshark:latest
    container_name: wireshark
    cap_add:
      - NET_ADMIN
    security_opt:
      - seccomp:unconfined #optional
    network_mode: host
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Etc/UTC
    volumes:
      - /path/to/config:/config
    ports:
      - 3000:3000 #optional
      - 3001:3001 #optional
    restart: unless-stopped

docker cli (click here for more info)

docker run -d \
  --name=wireshark \
  --net=host \
  --cap-add=NET_ADMIN \
  --security-opt seccomp=unconfined `#optional` \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Etc/UTC \
  -p 3000:3000 `#optional` \
  -p 3001:3001 `#optional` \
  -v /path/to/config:/config \
  --restart unless-stopped \
  lscr.io/linuxserver/wireshark:latest

Parameters

Docker images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal> respectively. For example, -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 outside the container.

Ports (`-p`)

Parameter	Function
`3000`	WireShark desktop gui, only use this if you are not using host mode and sniffing Docker network traffic.
`3001`	WireShark desktop gui HTTPS, only use this if you are not using host mode and sniffing Docker network traffic.

Networking (`--net`)

Parameter	Function
`--net=host`	Use Host Networking

Environment Variables (`-e`)

Env	Function
`PUID=1000`	for UserID - see below for explanation
`PGID=1000`	for GroupID - see below for explanation
`TZ=Etc/UTC`	specify a timezone to use, see this list.

Volume Mappings (`-v`)

Volume	Function
`/config`	Users home directory in the container, stores program settings and potentially dump files.

Miscellaneous Options

Parameter	Function
`--security-opt seccomp=unconfined`	For Docker Engine only, many modern gui apps need this to function on older hosts as syscalls are unknown to Docker.

Portainer notice

{% hint style="warning" %} This image utilises cap_add or sysctl to work properly. This is not implemented properly in some versions of Portainer, thus this image may not work if deployed through Portainer. {% endhint %}

Environment variables from files (Docker secrets)

You can set any environment variable from a file by using a special prepend FILE__.

As an example:

-e FILE__PASSWORD=/run/secrets/mysecretpassword

Will set the environment variable PASSWORD based on the contents of the /run/secrets/mysecretpassword file.

Umask for running applications

For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional -e UMASK=022 setting. Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.

User / Group Identifiers

When using volumes (-v flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user PUID and group PGID.

Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

In this instance PUID=1000 and PGID=1000, to find yours use id user as below:

  $ id username
    uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)

Docker Mods

We publish various Docker Mods to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.

Support Info

Shell access whilst the container is running:
- docker exec -it wireshark /bin/bash
To monitor the logs of the container in realtime:
- docker logs -f wireshark
Container version number
- docker inspect -f '{{ index .Config.Labels "build_version" }}' wireshark
