NP04 DAQ Configuration Editor

Preliminaries

This page provides instructions for viewing and editing configuration parameters of the artdaq system running on np04-srv-010.cern.ch. Artdaq configurations are stored in the online configuration database, which is accessible from the command line and web interfaces. This page describes how to view and edit artdaq configurations using the web interface, also known as the web config editor.

Network Access

The web config editor is a nodejs application that is running on the localhost:8880 of np04-srv-010.cern.ch, and hence it is not directly accessible from the Internet. To access the web config editor users can either launch a web browser directly on np04-srv-010.cern.ch or port-forward a connection over ssh and launch a web browser locally on their's laptop or desktop. The latter is a preferred option that requires adding the following snippet to the user's local ~/.ssh/config file and ssh-ing into cern-pddaq. The ssh session creates the needed port-forwarding and users can access the web config editor from the localhost.

Instructions for configuring the ssh port-forwarding.

ssh -l <your lxplus user account> cern-pddaq

URL: http://localhost:8880/db/client.html

Note: you will be prompted twice to enter a password, the first password to enter is the password for your personal user account on lxplus, and the second password is the password for the pduser user account on np04-srv-010.cern.ch.
