UNIX System Management: Configuring IP Connectivity

To complete this chapter, you can do the following things:

Configure the software and drivers for a newly installed network adapter.

Configures and browses the host name of the system as a command line.

Configures and browses the IP address of the system on a command-line basis.

After installing a new NIC, modify the Hosts file.

1. Network Map

The system administrator should have a network map that includes all of the LAN hardware that he manages. This network diagram should at least have:

The approximate size of the building or room in which the LAN resides

Type of LAN cable, including the type of Terminator

Forwarders, hubs, bridges, routers, and gateway locations

The location of each node, and each node:

Host Name

IP Address

Link-Layer Address

Hardware address of the network card

Operating System Information

You can use an online working form that includes all the information that you don't need to graphically describe: host name, real name, LAN type, IP address, link layer address. Lanic address operating system type, and so on.

Some tools, such as HP Open view, provide a graphical interface to your network diagram, and you can use a http://www.aliyun.com/zixun/aggregation/14045.html "> network management system and Simple Network Management Protocol (SNMP) To manage your network. HP Open View consists of several sub products, each of which can be purchased separately

2. Configure IP network via/etc/rc.config.d/netconf

Scripts/sbin/init.d/hostname and/sbin/init.d/net are executed when the system is started. Both startup scripts read configuration parameters from the configuration file/etc/rc.config.d/netconf and use these parameters for system initialization.

The commands that are executed in these scripts are:

Hostname Set the host name of the system

Ifconfig set IP address, subnet mask, and local loop address

Route add records to the system's routing table
