General
See: http://www.tcpipguide.com/free/t_NetworkingFundamentals.htm
The campus network uses Ethernet network devices connected via network switches using the TCP/IP internetworking protocols.
Networks
Basic network hierarchy is as follows;
LAN -> CAN/MAN -> WAN
Wikipedia info links;
- http://en.wikipedia.org/wiki/Computer_network
- http://en.wikipedia.org/wiki/Local_area_network. LAN. Connects PC's in one building.
- http://en.wikipedia.org/wiki/Campus_Area_Network. CAN. Connects small LAN's.
- http://en.wikipedia.org/wiki/Metropolitan_area_network. MAN. Connects LAN's and CAN's in a large area such as a city, campus or town.
- http://en.wikipedia.org/wiki/Wide-area_network. WAN. Connects MAN's in a country to another large geographical area.
Network Device Config
Basic network config for each network card usually requires the following sequence;
MAC address -> IP address -> Hostname
In addition each network card must know of the following;
- LAN Gateway address
- LAN Subnet Mask
Wikipedia info links;
- http://en.wikipedia.org/wiki/Network_card. The network interface card (NIC) is the device installed in the computer to enable networked communications.
- http://en.wikipedia.org/wiki/MAC_address. The hardware address of the NIC used for local area network (LAN) management together with the Ethernet protocol.
- http://en.wikipedia.org/wiki/Ethernet. Protocol used in LAN's communications.
- http://en.wikipedia.org/wiki/IP_address. Protocol used in metropolitan area network (MAN) and wide area network (WAN) communications.
- http://en.wikipedia.org/wiki/Gateway_address. The IP address on the LAN of the device which is connected to another LAN.
- http://en.wikipedia.org/wiki/Subnet_Mask. Method used to maximise use of IP address's and identify LAN.
- http://en.wikipedia.org/wiki/Dynamic_Host_Configuration_Protocol. Protocol to assign an IP address to a network card using the MAC address.
- http://en.wikipedia.org/wiki/Domain_Name_System. Protocol to assign a human readable name (hostname) to an IP address.
Local links
- Check out: ftp://ftp.ee.sun.ac.za/ubuntu/books/Networking for books regarding networking.
- Take note of: ftp://ftp.ee.sun.ac.za/ubuntu/books/Networking/Remote-Access-via-SSH.pdf for remote logins.
Test IP Address
One IP address is available for testing and should not be used permanently.
hostname = install.lib.sun.ac.za
ipaddress = 146.232.72.106
netmask = 255.255.255.254
gateway = 146.232.72.1
