CDOT Development Systems

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 on both Freenode and Moznet.
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:

• Shutdown the VM when not in use

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

To configure this on a Linux/Unix/OSX system for which you do not have administrative rights, use the LOCALDOMAIN environment variable. For example, you could add this line to your ~/.bash_profile or ~/.profile:

export LOCALDOMAIN="cdot.proximity.on.ca senecac.on.ca senecacollege.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:
142.204.133.7       canada

142.204.133.123     liberia
142.204.133.124     newzealand

After doing this, you can access the machines by name: ssh userid@liberia

CDOTnet

A gigabit ethernet LAN connects the PCs in the south end of CDOT (Australia, India, China, Ireland, and Scotland). The IP addresses on this LAN are 172.30.30.X, where X is the same last octet as the machine's external interface. These machines have DNS entries within the cdot.proximity.on.ca subdomain which are the same as the hostname with "2" appended (e.g., india2.cdot.proximity.on.ca refers to the CDOTnet interface on the host "india").

CDOTnet has no external interface and is therefore only useful for communication between the machines directly connected to it.

Summer 2010 Reassignments and Upgrades

For summer 2010 we will be reassigning machines and performing upgrades. We may need to consolidate services in order to do this.

Machines which have important data/software/services:

• Australia: DXR
• Scotland: RPM repositories
• HongKong: ARM Koji-Hub
• Ireland: Videos
• Others???

Machines which can probably be reinstalled without saving/moving data (?):

• Germany
• Liberia
• China
• India
• New Zealand (???)

Resources

• Reinstalling GRUB (needed to restore access to Linux when Windows is installed after Linux): http://dailypackage.fedorabook.com/index.php?/archives/161-System-Recovery-Week-Dealing-with-Disk-Images.html
