Use Your CS Account

• There are two Linux servers (pc00.cs.siu.edu and pc01.cs.siu.edu) that allow CS students 24/7 SSH and SFTP remote access regardless of being on-campus or off-campus. You can use ssh client or sftp client with your Linux account to remote access those two servers.
• On-Campus
  • You can access all computers in CS Labs (except Hands-on Lab) with your SIU credentials.
• Off-Campus
  • Besides pc00.cs.siu.edu and pc01.cs.siu.edu servers, you need to install and run SIUC VPN client in order to use other CS facilities like MySQL database. For more details on SIUC VPN client, please visit SIU Wireless.

Academic Personal Disk Quotas

• Account quotas are put in place on pc00.cs.siu.edu and pc01.cs.siu.edu
• To check your current quota usage
  • Linux: in a terminal, run $ quota -v loginID to see the usage.
• To prevent data loss and account lock-out, you should check your account quota regularly.

Using CS Database Server

Create your personal MySQL database via ssh to the following server:

$ ssh siu85xxxxxxx@pc00.cs.siu.edu
<Authenticate with your password and ssh key pair authentication>

The following command will create or renew database access for six months.
$ createdb

Accessing CS Database Server:

You must connect to the MySQL (MariaDB) server with TLS!

MySQL Access Hostname: dbserv.cs.siu.edu
Port Number: 3306

Client connections to the MariaDB Database (MySQL) server require the MariaDB client.

$ mysql -u siu85xxxxxxx -p -h dbserv.cs.siu.edu --ssl
