how to change network information of sun solaris systems

people new to networking under solaris seem to wonder how to change the ip-address or hostname of a machine regularly. so here you go, this is the list of files to change when updating your network information.

for ip changes edit the following files:

• /etc/hosts
• /etc/defaultrouter
• /etc/netmasks
• /etc/inet/ipnodes (if it contains the accordant entry for your hostname)

to change the hostname of a solaris system edit these files:

• /etc/hosts
• /etc/nodename
• /etc/hostname.xyz (xyz stands for the corresponding network interface, such as bge0)
• /etc/net/ticlts/hosts (obsolete in Solaris 10)
• /etc/net/ticots/hosts (obsolete in Solaris 10)
• /etc/net/ticotsord/hosts (obsolete in Solaris 10)
• /etc/inet/ipnodes (if it contains the accordant entry for your old hostname)

you do not need to reboot your machine to apply this new information (this is unix, remember? ) – all you need is to restart the adequate service using the service management facility (smf):

svcadm restart svc:/milestone/network:default
