CBDS

Introduction

This covers some tasks required for managing users and systems for CBDS.

Prerequisites

  • Knowledge of managing users in Linux
  • Knowledge of creating WUIT ServiceNow Catalog tickets
  • Access to servers required to complete the tasks.
  • Some tasks require CyberArk access in order to make changes to Active Directory (AD).
  • [OPTIONAL] Knowledge of SAS Management Console

Servers

  • CBDS Servers in biostats.wusm.wustl.edu domain

    • Supporting Systems

      Host Name VIP OS Purpose
      arachne 10.27.32.10 Linux CBDS HTTP, Request Tracker 5 server
      jackdaw 10.27.32.50 Linux CBDS NAS server
      wubios 10.27.32.1 Linux Legacy HTTP, SMTP, Sympa server

    • Saturn HPC Cluster

      Host Name VIP OS Status Purpose
      saturn 10.27.32.65 Linux Online CBDS HPC login node
      saturn1 10.27.32.75 Linux Online CBDS HPC compute node
      saturn2 10.27.32.76 Linux Online CBDS HPC compute node

Tasks

Create Student Home Directories

Before anyone can have a home directory, be added to an Analysis Account, or access the Saturn or Student clusters, their WUSTL Key must be active.  Stop now if they cannot send or receive email using their WUSTL Key.  Before you can log into either bullion or jackdaw you must be either on the WUSM VPN or on the WUSM campus network.
  1. Log into bullion.biostat.wusm.wustl.edu via SSH (e.g. PuTTy, terminal, WSL, PowerShell and SSH, or Command and SSH). Shown using PowerShell and SSH:
    empty
  2. Execute “sudo newuser-bullion WUSTLKeyUserName” where “WUSTLKeyUserName” is the user’s WUSTL Key Account name. “WUSTLKeyUserName” is normally the same as the user’s name preceding the “@” in their email address, but this is not always true.
    empty
    • The important thing to note above is the “OK” status for each of the servers contacted. The list of server names will change over time.
    • We executed newuser-bullion for the username “testuser”, which does not exist at WUSTL. That is why this error is indicated towards the top: “chown: invalid user: ‘testuser:testuser’” . Report any errors to Systems Managers.

New Personnel

  • Receives personal NAS share on Jackdaw.
  • Normally needs to be added to Analysis (or Project) Accounts. These are just AD Groups.
    • Requires CyberArk and ADUC Access. Request through WUIT ServiceNow Service Catalog

Create Faculty and Staff Home Directories

  1. Log into jackdaw.biostat.wusm.wustl.edu via SSH (e.g. PuTTy, terminal, WSL, PowerShell and SSH, or Command and SSH). Shown using PowerShell and SSH:
    empty
  2. Execute “sudo newuser-sasaccess ” where “” is the user’s WUSTL Key Account name. “” is normally the same as the user’s name preceding the “@” in their email address, but this is not always true.
    empty
    • The important thing to note above is the “OK” status for each of the servers contacted. The list of server names will change over time.
    • We executed newuser-sas-access for the username “testuser”, which does not exist at WUSTL. That is why this error is indicated towards the top: “chown: invalid user: ‘testuser:testuser’” . Report any errors to Systems Managers.

Create new Analysis (or Project) Account

  • Requires CyberArk and ADUC Access
    • Request through WUIT ServiceNow Service Catalog
  • May only be requested by PI, management, or leadership.

    • Log into jackdaw.biostat.wusm.wustl.edu via SSH (e.g. PuTTy, terminal, WSL, SSH). Shown using WSL and SSH:
      empty

    • Execute “sudo newuser-analysis ProjectName” where “ProjectName” is the name of the Project as defined by the requestor.

    • The important thing to note in the output is the “OK” status for each of the servers contacted. The list of server names will change over time.

Map NAS shares

  • UNC path is \jackdaw.biostat.wusm.wustl.edu\SHARE_NAME.

Request SAS

  • Requires WUIT ServiceNow Service Catalog request and CC with approval for funding.
