Student and Faculty Use Servers

The CS Department provides both Linux servers for use by CS students. To learn how to connect to these servers, please visit the SSH Access page.


Linux Servers

linux.cs.odu.edu may be used to connect to the load-balanced linux cluster. The old records atria.cs.odu.edu and sirius.cs.odu.edu will also take users to the new load-balancer.

The individual severs require that you be on the VPN to connect to them. They reside on the following records:

betelgeuse.infra.cs.odu.edu canis.infra.cs.odu.edu aspidiske.infra.cs.odu.edu scorpii.infra.cs.odu.edu

Cronjobs

The new servers share crontab between all servers in the cluster. This means that by default a cronjob set on one server will run on all four. If you want your cronjob to run on only a specific server you can preface the job with control statements:


[ "$(hostname)" != "canis" ] || [ "$(hostname)" != "aspidiske" ] || "$(hostname)" != "betelgeuse" ...

Which would result in this cronjob running on scorpii only.

Home Directory

When you log in to your Unix account, you are placed in your "Unix home directory". This will be the main working directory every time you log in. You can create and keep sub-directories,files and other important data in this directory.

Your home directory is backed up so it is advised to keep your data here. What is more, your Unix home directory gets mapped as your Windows Z-Drive so that you can share data between operating systems. Your Z-Drive can also be mapped to Apple Mac machines. To learn how you can do this, visit the Z-Drive Mac page.


Unix Permissions

Your security is important to us, and it should be very important to you. When you create files in your Unix home directory, you should be aware of the permissions you can set on these files. These permissions will determine whether or not your information can be viewed by other students in the department.

To understand how you can correctly set Unix permissions, please view the Unix Permissions page.

FTP Services

All files in your home directory can be access via FTP connection. To learn more, visit the FTP Services page.
