Installing and Conﬁguring Internet Services

Conﬁguring Internet Addresses

ROUTE_DESTINATION[1]="15.13.131.0"

ROUTE_GATEWAY[1]="15.13.131.213"

ROUTE_COUNT[1]="0"

3. If you will not be using gated, conﬁgure routes to all the networks

you need to reach. Type the following command for each network you

need to reach from your host:

/usr/sbin/route add net network_address gateway_address

Then, create a new set of routing variables in the

/etc/rc.config.d/netconf ﬁle for each new route. Whenever you

create a new set of variables, increment the number in square

brackets.

ROUTE_DESTINATION[n]="network_address"

ROUTE_GATEWAY[n]="gateway_address"

ROUTE_COUNT[n]="1"

If ROUTE_GATEWAY[n] is your own host, set ROUTE_COUNT[n] to 0.

Otherwise, set it to 1.

4. Type the following command to verify the routes you have conﬁgured:

/usr/bin/netstat -r

For more information on static routing, type man 1M route or man 7

routing at the HP-UX prompt.

If you have a large and complicated network, use gated for dynamic

routing. See “Conﬁguring gated” on page 235 for more information.

To Change a Host’s IP Address

When you use SAM to change a host’s IP address, SAM does not perform

all these steps. For example, SAM does not update BIND or NIS

databases.

1. Change the host’s IP address in the /etc/hosts ﬁle. See “To Edit the

/etc/hosts File” on page 36.

2. Change the IP_ADDRESS[n] variable in the

/etc/rc.config.d/netconf ﬁle to the new IP address.

3. If the host is on a network that uses BIND, change the host’s IP

address in the data ﬁles of the authoritative name servers. See

“Conﬁguring and Administering the BIND Name Service” on page
