Step 4. After Ubuntu Installation
Network registration
You need to contact the campus network administrator and register your servers MAC address for TCP/IP hostname registration.
To determine what network interfaces are available, see: http://www.cyberciti.biz/faq/linux-list-network-cards-command
To get your servers MAC address type the following in a terminal as the dspace or root user:
sudo ifconfig
Something like the following should scroll by:
dspace@ir2:~$ sudo ifconfig
[sudo] password for dspace:
eth0 Link encap:Ethernet HWaddr 00:0c:29:02:3e:00

RX bytes:1171132031 (1.0 GB) TX bytes:1171132031 (1.0 GB)
Take note of: HWaddr 00:0c:29:02:3e:00 from the third line above, this is the MAC address that your campus network administrator will need in order to register your server. Of course yours will be different to the one above. MAC address's are normally unique per network adapter per computer.
Server Static IP address assignment
See: http://www.tecmint.com/set-add-static-ip-address-in-linux
There are two options for network setup:
- a) Use a static IP address
- b) Use DHCP for assigning the IP address.
It is good practice to use the static method for assigning the IP address. Request the campus network administrator to do so.
We use static network registration for all our servers. Below is an example of our servers network config file in: /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 146.232.66.15
netmask 255.255.254.0
network 146.232.66.0
broadcast 146.232.67.255
gateway 146.232.66.1
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 146.232.128.1 146.232.128.10
dns-search *.sun.ac.za
dns-domain sun.ac.za
Type the following to setup the network interface. This can only be done after the campus network administrator has registered your server on the network.
sudo nano /etc/network/interfaces
Apply the network settings given to you by the campus network administrator.

Setup the software repositories
After you have correctly registered your servers TCP/IP hostname, then you can setup the software repositories.
Step 1
On your client PC with the Ubuntu desktop installed, open a command line terminal by typing the following:
CTL+ALT+t
Step 2
Login to your remote server as the "dspace" user by typing as follows in the terminal.
ssh dspace@%hostname%
Replace %hostname% with the hostname of your server.
Step 3
Type the following in a console/terminal/xterm to back up the original file:
sudo cp /etc/apt/sources.list /etc/apt/sources.list-original
Type the following in a console/terminal/xterm to edit a new file:
sudo nano /etc/apt/sources.list
Tip: It is always a good idea to maximise the open nano window so that the copy and paste of long lines does not wrap around.
Step 4
- FOR UBUNTU 16.04
Delete all of the existing contents in the /etc/apt/sources.list file using the CTL+K key repeatedly and then add the following using the copy and paste functions of "nano" and "firefox";

Step 5
To update the repository list, type:
sudo apt-get update
Step 6
To upgrade to the latest software., type:
sudo apt-get dist-upgrade
Step 7
If this server is running on a VMWare host server, then setup the VMWare client tools by clicking on the link below.
http://ubuntu.sun.ac.za/wiki/index.php/VMWare-Tools
Optional - Virtualbox Network Setup
If testing using Virtualbox, then setup the network as follows;
With VM powered down
- Click File > Preferences > Networks Under NAT Networks if you don't see a NAT Network click on + icon to add NAT Network.
- Click Host-Only Networks if you don't see a host only network click + icon to add one
- With the VM selected, click Settings > Network then click on Adapter 1 and choose Bridged Adapter
- With the VM selected, click Adapter 2 and choose Host Only Adapter
Start up VM
In order to see network adapter you need to type
ifconfig -a
You may see the network adapter is added with a mac address but not an IP?
If so then you need to edit /etc/network/interfaces in order to configure DHCP. Example below using "nano" but you can use editor of your choice
sudo nano /etc/network/interfaces
add the lines
auto eth1
iface eth1 inet dhcp
save and exit file.
Then try restarting network service using below command
sudo service networking restart
Or if that fails then restart VM.
Once restarted type below to see if you eth1 has been allocated an IP address
ifconfig -a
if so then see if you can SSH on to the VM.
