Changing the IP Address in Solaris 11

Question

I am trying to change the IP address in Solaris, but am failing to do so.

The IP address needs to be a fixed number, like 10.0.11.10

I have tried changing the IP address in /etc/hosts which I changed the hostname and the IP address, but when I try ping the computer name, it says:

Ping request could not find host SolarisTest. Please check the name and try again.

I have done what they told me to try on this site. But still stuck.

They say to do this: "If using Solaris 9 or above, users may need to edit the IP address in /etc/inet/ipnodes" which I did, and the file looks exactly the same as the /etc/hosts/ file. I already changed the IP address in the /etc/hosts/ file.

• Please can someone show me how to change the IP address on Solaris 11?

Edit

I have tried ifconfig -a and it showed me the old IP address 10.0.10.80 and I changed /etc/hosts/ to show 10.0.11.10 - so I have no idea why it is always changing.

2nd Edit

This link also shows stuff about how to change the IP address, as I have tried that as well, and also got nowhere.

Answer 1

According to the Solaris 11 network interfaces manual in chapter 8 “Configuring an IP Interface”:

ipadm create-addr -T static -a 10.0.11.10/24 eth0/staticip

eth0 is the name of the Ethernet interface (listed by ipadm show-if). staticip is a name that you can choose.

Assuming you are on Solaris 11:

I believe the above answer is too simplistic.

I've got a feeling that your current IP address is obtained via DHCP and now you want to switch to a fixed address ?

First you need to disable Network Automagic. (it will get in your way if all you want is a static IP address). Do it like this:

netadm enable -p ncp DefaultFixed

Next step is that you must explicitly create an IP interface. (because you've disabled network automagic). Do it like this:

ipadm create-ip net0

Now go ahead and assign a static IP address on that IP interface:

ipadm create-addr -T static -a 10.0.11.10/24 net0/v4

That's it. No need to reboot.

I don't know what netmask you want to use so the "/24" (equivalent of mask 255.255.255.0) is a guess. The "v4" means that you want to create an IPv4 address as opposed to a IPv6 address.

I know you already sorted it out a long time ago using the GUI but, for the record, the way to overcome from the command line the issue you experienced :

# ipadm create-addr -T static -a 192.168.1.100/24 net0/v4static
ipadm: cannot create address: Persistent operation on temporary object

is to turn interface persistence on by recreating it:

# ipadm show-if -o all net0
IFNAME     CLASS    STATE    ACTIVE CURRENT       PERSISTENT OVER
net0       ip       down     no     bm4---------  ----       --
# ipadm delete-ip net0
# ipadm create-ip net0
# ipadm create-addr -T static -a 192.168.1.100/24 net0/v4static
# ipadm show-if -o all net0
IFNAME     CLASS    STATE    ACTIVE CURRENT       PERSISTENT OVER
net0       ip       down     no     bm46--------  46--       --
# ifconfig net0
net0: flags=100001000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4,PHYSRUNNING> mtu 1500 index 6
        inet 192.168.1.100 netmask ffffff00 broadcast 192.168.1.255
        ether 0:14:4f:12:34:56
