Virtual Private Server (VPS)

In the context of this course, students will be offered their own (container-based Linux) Virtual Machine! This will allow the students to have "root" access and carry out the course assignments. Particularly, we use OpenVZ virtualization.

The specs of the VPS are minimal (but adequate for the purpose of this course):

The given machine can be accessed in the following ways. Please notice that your VPS is only accessible from the local Departmental network. To access your VPS from home, please use one of the below:

  1. VPN to the Department (check GUIDE)
  2. SSH to one of the 103 / B103 machines (103ws1 ... 103wsN and b103ws1 ... b103wsN)
  3. ssh –l root .in.cs.ucy.ac.cy, where is provided by the laboratory TA.

To install a service to your VPS use the following:

# Define the software package repository

$ export http_proxy='http://proxy.cs.ucy.ac.cy:8008'

# To install some software use yum (e.g., vsftpd)

$ yum install vsftpd

# To check the service status

$ service vsftpd status

# To start the service

$ service vsftpd start

“Starting vsftpd for vsftpd: [ OK ]”

# To edit the configuration file

$ vi /etc/vsftpd/vsftpd.conf

# To restart service

$ service vsftpd restart

“Shutting down vsftpd: [ OK ]”

“Starting vsftpd for vsftpd: [ OK ]”

# To shutdown service

service vsftpd stop

“Shutting down vsftpd: [ OK ]”
