Important

  • When copy any code, don't copy the following mentioned symbols at the beginning of each line.

  • "$" precedes Linux commands that are typed at a regular user's shell prompt, usually your host machine

  • "#" precedes Linux commands that are typed at a root shell prompt, usually in a VM

  • Machines in the lab cannot connect to Internet but you are able to do yum install basic software with local yum repositories.

  • All assignments should be done in the lab.

  • Please back up everything you need for later use to NAS. If you don't, it's possible that your data or VMs get destroyed.

Import VM from NAS

A network attached storage (NAS) is used to store all iso images, scripts, as well as your backups.

[username@clemson11 ~]$ sftp username@192.168.10.5:VMs/Assign1_VM.ova .
username@192.168.10.5's password: 
Connected to 192.168.10.5.
Fetching /VMs/Assign1_VM.ova to ./Assign1_VM.ova
/VMs/Assign1_VM.ova                                                                                               100% 2352MB  72.0MB/s   00:32    
sftp> exit
[username@clemson11 ~]$ vboxmanage import Assign1_VM.ova

For students in Charleston, use "sftp username@192.168.20.5".

Set up VM

Open Oracle VM VirtualBox

Oracle VM VirtuaBox

Click on Settings, make sure it attached to "Bridged Adapter", and click at the exchange button to generates a new random MAC address (next to MAC Address).

Start VM, login with username: root, password: root. Type "startx" to GUI.

Then change the password.

[root@localhost ~]# passwd

New password: 
BAD PASSWORD: The password is shorter than 8 characters
Retype new password: 
passwd: all authentication tokens updated successfully.
[root@localhost ~]#

Change IP address to the one given on first day of class. This step doesn't finish until you turn off network and then turn on.

For Charleston students, Address: 192.168.20.xxx, Gateway: 192.168.20.1

sftp> cd home/  
sftp> put -r VirtualBox\ VMs/Assign1_VM/
Uploading VirtualBox VMs/Assign1_VM/ to /home/Assign1_VM
