2. Log in as root.

3. Make a backup copy of the

/etc/rc.config file.

cp /etc/rc.config /etc/rc.config.BACKUP

4. Edit the

HOSTNAME entry in the /etc/rc.config file, changing the

entry for

oldname to newname.

Before:

HOSTNAME="

oldname.aaa.bbb.ccc"

After:

HOSTNAME="

newname.aaa.bbb.ccc"

5. Make a backup copy of the

/etc/hosts file.

cp /etc/hosts /etc/hosts.BACKUP

6. Edit the

/etc/hosts file , changing the entry for oldname to

newname

.

Before:

IPaddress oldname.aaa.bbb.ccc oldname

After:

IPaddress newname.aaa.bbb.ccc newname

7. Optionally edit and change the file name of the file corresponding to

oldname

(it may be in uppercase characters) in the /usr/sys/conf

directory; this example shows one method for doing this.

#

cd /usr/sys/conf

#

ls

GENERIC

...

OLDNAME

#

sed -e "s/OLDNAME/NEWNAME/" OLDNAME > NEWNAME

#

rm OLDNAME

8.  Reboot the system with the

shutdown -r command.

Be sure to warn users and give them adequate time to save their files,

exit their applications, and log off.

The following is an example that reboots the system in one hour and

displays a message.

#

/usr/sbin/shutdown -r +60 \

System going down in 1 hour! Save your files and log out!

9. Edit the root

.profile, .kshrc, .login, .cshrc, and .rhosts files

as needed to reference the new system name; pay particular attention

to the setting of the

DISPLAY and PS environment variables.

10. Inform other users of the system name change; they may need to

edit their

.profile, .kshrc, .login, .cshrc, and .rhosts files

accordingly.
