This is the procedure to change and IP address and hostname in solaris (v440). It is best to be connected by serial port or net sc.
Find the existing IP address
# ifconfig -a
bring down the port
# ifconfig 'port' down
When you see the existing details, update accordingly. This assumes netmask and broadcast are being changed too where x is details
# ifconfig 'port' inet xxx.xxx.xxx.xxx netmask xxx.xxx.xxx.xxx broadcast xxx.xxx.xxx.xxx
Make a copy of the hosts file
# cp /etc/hosts /etc/hosts.bak
edit the hosts file with the new IP address. If necessary, do the same on /etc/netmask
Restart the inet service, this will assign the new values
# /etc/init.d/inetsvc stop
# /etc/init.d/inetsvc start
if you need to change the default route, find the existing one with
# netstat -nar
to delete the existing route
# route delete default 'defaultroute'
then add it with
# route add default 'defaultroute'
make a back up of /etc/defaultroute and modify it.
To change the hostname, make a backup of hosts and modify /etc/hosts. Then make a back up of the following files and modify all
and rename directory under /var/crash
# cd /var/crash
# mv oldname newname
then reboot the server to ensure all changes have taken effect.
