Setting up the chatbot Go-neb for the messaging server Matrix

Go-neb is a chatbot that provides services such as The automatic sending of RSS news feeds, searching for GIF images or information from Wikipedia and many other functionalities. The chatbot is easy to set up and can then be used via the messaging client Riot (client for the matrix server).

In this tutorial the chatbot is installed with all its requirements. Root is used here. However, a previously running and configured Matrix Server instance is required. The installation of Matrix via "Prebuild Packages" is recommended. More information about installing and configuring Matrix:


Installation of GO

If GO is already installed and configured, this section can be skipped.

GO can be downloaded from this website. Please download the latest version for Linux:


Then unpack the downloaded file.

tar -zxvf go1.10.1.linux-amd64.tar.gz -C /usr/local/


Then set the paths on the operating system. The paths must point to the folder where GO was downloaded.

export GOROOT=/usr/local/go
export PATH=$GOROOT/bin:$PATH

With this command you can check whether GO is now called and you can display all set paths for GO.

go env

Instead, the version command can be used to display the version of GO.


Installation of go-neb

Change to the path where you want the program installed. The path /opt is used here because the program is installed manually.

cd /opt

Now use git to download the software.

git clone
cd go-neb

The program gb must now be downloaded and installed in the folder go-neb.

go get -u

Now you can install go-neb. Go-neb can be installed with the program gb. Gb must be called with the full path.

/root/go/bin/gb build


Configuration of go-neb

Now you have to create a user (go-neb) for the chatbot, which has no Sudo rights and can be used with the home directory /opt/go-neb

Create the group go-neb and add the user go-neb to this group. Don't forget to give access rights to the folder of the program go-neb for the now created user go-neb.

chown -R go-neb:go-neb /opt/go-neb


Create a new user in Matrix for the chatbot. Here the user bot is used for go-neb.

register_new_matrix_user -c /etc/matrix-synapse/homeserver.yaml https://localhost:8448


Go-neb can be executed directly using this command:

BIND_ADDRESS=:4050 DATABASE_TYPE=sqlite3 DATABASE_URL=go-neb.db?_busy_timeout=5000 BASE_URL=http://localhost:4050 bin/go-neb

Here, however, a system service for this program is created for production use.

vim /etc/systemd/system/go-neb.service
Description=Go-neb bot for matrix-synapse server
Environment=BIND_ADDRESS=localhost:4050 DATABASE_TYPE=sqlite3 DATABASE_URL=db/go-neb.db?_busy_timeout=5000 BASE_URL=http://localhost:4050 CONFIG_FILE=config.yaml


Now configure the settings of the chatbot go-neb. The configuration file must be copied and can then be customized according to your needs.

cp config.sample.yaml config.yaml

The chat bot is set up in this section t. Multiple users (clients) can be used for the chat bot. Only one user is set up here. Please enter the AccessToken defined in the Matrix configuration. UserID corresponds to the user account in the Matrix server.

  - UserID: "@bot:localhost"
    AccessToken: "XXXXXXXXXXX"
    HomeserverURL: "http://localhost:8448"
    Sync: true
    AutoJoinRooms: true
    DisplayName: "Go-NEB Chatbot"

The functions of the chatbot can be set up in this section "services". You can also add your own services here. New Api keys have to be created. The Api keys in the configuration do not work.

# The list of services which Go-NEB is aware of.
# Delete or modify this list as appropriate.
# See the docs for /configureService for the full list of options:
  - ID: "giphy_service"
    Type: "giphy"
    UserID: "@goneb:localhost" # requires a Syncing client
      api_key: "XXXX"
      use_downsized: false

Now activate and start the newly created service.

systemctl enable go-neb
systemctl start go-neb


Further information

There are other settings than those mentioned here. The functionality of Go-neb can also be extended by self-programmed services. For the service guggy there are no more API keys on the part of the operator.
