Jump to: navigation, search

We have a group account on the JLab CUE for gluex-related tasks that are generally helpful for the entire collaboration. The username is "gluex" and is a member of the "halld" unix group.

Uses of the gluex account

Some of these tasks are run in cron jobs. By having them in a group account we can have more than one person have access to the crontab and the scripts, and it facilitates having a standard environment, i. e., it frees individuals to change the environment in their private accounts at will and not worry about breaking public jobs.

Another task is creating the standard builds of the offline software. Since all the files are owned by the system account, indiviual users cannot inadvertently overwrite or modify these builds.

How to log into the account

This account does not have a password; it is accessed exclusively by ssh using your public/private key pair. To log into the account you have to have your public key on file in the gluex account in the file /home/gluex/.ssh/authorized_keys. Contact the Software Coordinator (or any person who currently has access to the account) to have your public key added.
