HP-UX networking related tools and commands

Posted by Vivek Gite [Last updated: August 31, 2005]

As my journey continues to exploring HP-UX I found couple of nice utilities and tools to configure and administrate HP-UX networking subsystem.

FILES

/etc/hosts - Hosts configuration file (resolve hosts and IPs)
/etc/rc.config.d/netconf – IP address, routeing address and hostname stored in this file

SCRIPTS

/etc/init.d/net start – Use to start, stop network service

HPUX Commands
(a) Display lan interface info:
# lanscan

(b) All in one lan configuration utility (lan0 is first Ethernet interface) to configure and view the system IP address:
# ifconfig lan0 - Display IP info such as IP address netmask etc.
# ifconfig lan0 up - Up network interface (allow traffic)
# ifconfig lan0 down - Down network interactive (deny traffc)
# ifconfig lan0 192.168.1.1 netmask 255.255.255.0 up - Setup/change IP adddress

(d) Arp administration (cache)
# arp -a

(e) Display routing table/info:
# netstat -nr

(f) Define new route:
# route add default 192.168.1.254 1

(g) HP's LAN diagnostic tool
# lanadmin

(h) Test a remote host connectivity
ping host.mycorp.com

(i) Setup various lan properties, dns client, NIS client configuration etc using GUI tool:
# sam
# set_parms

(j) Check dns connectivity:
$ nslookup www.google.co.uk
