Changing a client's name (Managing NFS and NIS, 2nd Edition)

8.5. Changing a client's name

Update /etc/bootparams to reflect the new client's name and root and swap filesystem pathnames.
Add the new hostname to the hosts map in place of the old client name. If any mail aliases include the old hostname, or if the host is embedded in a list of local hostnames, update these files as well.
Modify the ethers NIS map if all hosts are listed in it.
Rebuild the bootparams, ethers, and hosts maps.

# cd /export/root 
# mv oldname newname 
# cd /export/swap 
# mv oldname newname

Update the server's list of exported NFS filesystems with the new root and swap pathnames. Also change the rw= and root options in /etc/dfs/dfstab. After modifying the file, share the newly named filesystems, or shareall filesystems, so that the client will be able to find them when it reboots.
In the client's root filesystem, modify its hosts file and boot scripts to reflect the new hostname:
```
# cd /export/root/newname/etc 
# vi hosts 
# vi hostname.*[0-9]*
# vi nodename
# vi /etc/net/*/hosts
```
In Solaris, the hostname is set in a configuration file with the network interface as an extension; for example: hostname.hme0. It is essential that the host's name and IP address in its own hosts file agree with its entries in the NIS map, or the machine either boots with the wrong IP address or doesn't boot at all.
