Changing a hostname

The following steps are required to change a Sun system's hostname.

• /etc/hosts.allow (to correct access permissions)
• /etc/dfs/dfstab on this system's NFS servers (to allow proper mount access)
• /etc/vfstab on this system's NFS clients (so they will point at the correct server)
• kerberos configurations
• ethers and hosts NIS maps
• DNS information
• Netgroup information
• cron jobs should be reviewed.
• Other hostname-specific scripts and configuration files.

Additional steps may be required in order to correct issues involving other systems.

Having said all that, the minumum number of changes required are:

• /etc/nodename
• /etc/inet/hosts (aka /etc/inet/ipnodes)
• /etc/hostname.*
• /etc/net/*/hosts (These are dynamically set at boot time in current Solaris 10 versions.)
