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  
          inet addr:146.232.129.131  Bcast:146.232.129.255  Mask:255.255.254.0
          inet6 addr: fe80::20c:29ff:fe02:3e00/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:81959326 errors:23 dropped:0 overruns:0 frame:0
          TX packets:55609424 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:3646385659 (3.3 GB)  TX bytes:1837131118 (1.7 GB)
          Interrupt:16 Base address:0x1424 

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:2843219 errors:0 dropped:0 overruns:0 frame:0
          TX packets:2843219 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          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";

deb ftp://ftp.sun.ac.za/ubuntu xenial main restricted universe multiverse
deb ftp://ftp.sun.ac.za/ubuntu xenial-updates main restricted universe multiverse
deb ftp://ftp.sun.ac.za/ubuntu xenial-security main restricted universe multiverse

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

  1. Click File > Preferences > Networks Under NAT Networks if you don't see a NAT Network click on + icon to add NAT Network.
  2. Click Host-Only Networks if you don't see a host only network click + icon to add one
  3. With the VM selected, click Settings > Network then click on Adapter 1 and choose Bridged Adapter
  4. 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.
