TCP-IP Configuration Conclusion

What are the key points to know about TCP-IP Configuration?

In this module you learned:
  1. How to set up the three key elements of TCP/IP configuration on a UNIX machine
  2. How to use the resolv.conf file
  3. How to use the nsswitch.conf file
  4. How to use the /etc/hosts file to arrange for name service
  5. How to use the ifconfig command to configure interfaces
  6. How to use the route command to manipulate the routing table
  7. The significance of the ARP cache, and how to examine it using arp

TCP-IP Glossary Terms

In this module, we introduced the following terms:
  1. Domain Name Service (DNS): Domain Name Service: resolves domain names to IP addresses
  2. Ethernet: A LAN developed by Xerox in 1976. Ethernet became a widely implemented network from which the IEEE 802.3 standard for contention networks was developed. It uses a bus topology and the original Ethernet relies on CSMA/CD to regulate traffic on the main communication line.
  3. Gateway: A machine which links two networks.
  4. Loopback address: 127.0.0.1. This address is used for diagnostics.
  5. Netmask : A 32-bit bit mask which shows how an Internet address is to be divided into network, subnet and host parts.
  6. Network Information Database: The NID (Network Information Database) provides a means to synchronize account information across computer systems.
  7. Point-to-point protocol (PPP): A protocol for connecting to the Internet. PPP provides error checking and compression of the IP and TCP headers.
  8. Resolver library: The TCP/IP protocol library software that formats requests to be sent to the Domain Name Server for hostname to Internet address conversion.
  9. TCP/IP: TCP/IP is the network protocol suite used by the Internet and most local area networks.
  10. Telnet: A TCP/IP application that is used for remote terminal access and can be used to administer a UNIX machine.

Linux Commands

In this module, we discussed the following commands:
Command Purpose
arp View and manipulate the ARP cache
dmesg Display boot messages
hostname Set the host name
ifconfig Configure an interface
netstat -nr Dump the routing table
ping Check for network connectivity
route View and manipulate the routing table
uname Return host name
