SCG

Hardware

• Scale 5027R 2U Xeon Dual Socket Server, 128G ram, 4 x 2T drives

OS

• Ubuntu 14.04 LTS AMD ALT 64bit

Hardware

* nScale 5027R 2U Xeon Dual Socket Server, 128G ram, 4 x 2T drives

CS AD setup

• The machine is part of the *CS Active Directory

Accounts

• To add or modify accounts: accounts@cs.uwaterloo.ca

Password Updates and LDAP

• scg.cs is using the CS Active directory passwords now - so use that password.
• Here are the rules for passwords and accessing scg.cs:
  • ssh keys still work and are recommended
  • When logging to scg.cs in try your Active Directory password - or if it fails try then try the first 8 characters or if it
• Password Update Rules:
  • if you ever set your CS core password - that will change your Active Directory password also
  • if you ever set your windows domain password - that will change your Active Directory password
  • If you change your scg.cs password it will change your active directory password.

• Aside: Not all CS hosts are using the Active Directory - yet - on the CS core when you update your password a special script also update the CS Active Directory to match - but it's really important to know that the CS Core does not actually authentic against the Active directory so there are times when both passwords can be different!

Virtual Machines

SCG"> Console access via SCG

• Must be root on scg.cs
  • ssh -X cscf-adm@scg.cs (2016 version)
  • sudo bash
  • your SSH login client must have X tunneling turned on
  • your login host must have xwindows running in order to display vmware
• run vmware - this takes you directly to the penmath console
• login with cscf-adm (2016 version)
• Note: when you are done , you quit vmware and pick "Run in background" as the quit option when prompted

Starting VM

• /etc/init.d/vmware_workstation_user start is used to start a vertual machine

Stopping VM

• /etc/init.d/vmware_workstation_user stop is used to stop a vertual machine

Checking Status

• /etc/init.d/vmware_workstation_user status reports running status
• With a running VM

           Total running VMs: 1
           /home/vmware/Debian-6-64/Debian 6 64-bit.vmx
        

• With NO running VM

           Total running VMs: 0
