CDOT Development Systems

Revision as of 22:02, 5 February 2009 by Chris Tyler (talk | contribs) (→‎Virtual Machines)

These machines are in the CDOT area on the first floor of the TEL building.

Ground Rules

  1. Take responsibility for your actions.
  2. Don't blow up other people's stuff.
  3. Expect other people to blow up your stuff.
  4. Don't turn these machines off.
  5. Before rebooting, check with the other logged-in users, and check on #seneca on IRC.
  6. Work under your own account, using root as sparingly as possible. If you need additional accounts, create them, but put your name in the comment (GCOS) field.
  7. Don't create public services.
  8. These machines are never backed up. Backup your own stuff, frequently.

Disk Space

Keep an eye on disk space -- both your own usage and the free space on the machine. Delete stuff you don't need (especially temp files and build debris).

Most of the CDOT machines have unassigned storage within their volume group. If you need additional space in a filesystem and know how to use LVM safely, feel free to allocate additional space as needed, but do not assign more space than required for your work (it's easier to add space to a filesystem than to remove it to add it to another filesystem). If you do not know how to administer LVM safely, ask an experienced user to add space to the filesystem for you -- it's very easy to destroy a filesystem. Please experiment with and learn about LVM on your own systems or in a virtual machine.

Virtual Machines

Please feel free to configure KVM virtual machines on the PCs. Because virtualization technologies conflict, please discuss the use of other hypervisors before deploying them.

When using virtual machines, please:

  • Use a logical volume (LV) for the VM image
  • Shutdown the VM when not in use

Connectivity Status

The connectivity of the systems is tested every 5 minutes using ICMP echo (ping) and may be viewed on the CDOT Development System Status page.

Machine names, IPs, and Status

Please update this information as you work on the machines' configuration.
To encourage less breakage, please put some information about what you are doing on a machine. A sample machine pages is located at CDOT_Development_Systems/ExampleSystem

Tip:

These hostnames have all been added to the cdot.proximity.on.ca domain for convenience. If you add that domain to your search domains in your DNS configuration, you can refer to the CDOT hosts by name. If you are using Linux or Mac OSX, you can add a search domain in your /etc/resolv.conf file by editing the search line: 

search whatever.was.already.here.com cdot.proximity.on.ca

Alternately, you can append the machine names and IPs to the hosts file (/etc/hosts on Linux and Mac OSX, c:\windows\system32\drivers\etc\hosts on Windows) -- do not delete the existing contents of that file, just add this text: 

# CDOT host file - from http://zenit.senecac.on.ca/wiki/index.php?title=CDOT_Development_Systems - 2009.01.28 version:
