Network Administration

Hostname:- To display name of the system

Ifconfig:-To display ip configuration of the system

lanadmin :-This HP-UX program administers and tests the Local Area Network (LAN). For each interface card, this command allows you to:

• Display and change the station address.

• Display and change the 802.5 Source Routing options (RIF).

• Display and change the maximum transmission unit (MTU).

• Display and change the speed setting.

• Clear the network statistics registers to zero.

• Display the interface statistics.

• Reset the interface card, thus executing its self-test

lanscan :-This command lanscan displays the following information about each LAN device that has software support on the system:

• Hardware Path

• Active Station Address (also known as Physical Address)

• Card Instance Number

• Hardware State

• Network Interface NamePPA

linkloop :-This command tests the connectivity of the local node and the remote node specified by each hardware station address

ndd :-This command allows the examination and modification of several tunable parameters that affect networking operation and behavior.

netfmt :-Use this HP-UX command to format binary trace and log data gathered from the network tracing and logging facility (nettl) and the kernel logging facility

nettl :-This command is a tool used to capture network events or packets. Logging is a means of capturing network activities such as state changes, errors, and connection establishment. Tracing is used to capture or take a snapshot of inbound and outbound packets going through the network, as well as loopback or header information.

netstat :- HP-UX operating system implement the netstat command to displays network statistics. There are differences in the options for each version:

HP-UX -g shows multicast information for network interfaces.

-v shows additional routing information.

ping :-The ping command uses the ICMP (Internet Control Message Protocol) protocol's mandatory ECHO_REQUEST datagram to elicit an ICMP ECHO_RESPONSE from the specified host or gateway host, where host is a network name or IP address. ECHO_REQUEST datagrams (pings) have an IP (Internet Protocol) and ICMP header, followed by a struct timeval and then an arbitrary number of pad bytes used to fill out the packet
