Hi,

 How can I permanently change the IP address of a SUN box.

 I tried the following:
 ifconfig eri0 192.168.1.57 up.

 I also tried :
 ifconfig eri0 plumb
 ifconfig eri0 192.168.1.57 netmask 255.255.255.0
up.

 It works until i reboot the box . Once rebooted I get the old IP
address 192.168.0.57.

 Regards,
 Nithin

man sys-unconfig

You can either use the command to reset networking and reconfigure following
a reboot or use the list of files given in the man page to ensure you've
updated everything that need to be changed.

Read the fine Manual ->

Just how did you think the box remembers its IP address????  It's stored 
in a file!  Look at /etc/hostname/eri*

you need to change coupe of files in etc than reboot
not the ifconfig cmd

I thought you had to solder in some jumpers on the NIC?

I mean after all, the OP did ask how to *PERMANENTLY*
change the IP -- ??

Hey, reading the manual is cheating!

I usually thrash around until I either get it to work right
or it breaks, and if it breaks, it probably needed replacing
anyway!

Well, you can wade through the 28 page chapter of the Fine Manual
that refers to this topic (yes, I counted the pages);

-- or you can do the following:

Create and edit file: /etc/hostname.eri0

(Generally, "/etc/hostname.{interface}", depending on what
sort of network card the box is using.)

Put in a hostname: say, "mybox"
(Be creative here. We had a customer that named all their
boxes something to the effect of "host01", "host02", etc.
How droll.)

If that's the official name for the host, you might want to
also put it into file "/etc/nodename".

Edit file: /etc/inet/hosts
(although I prefer the old link, "/etc/hosts", and will continue
using it until they take it away, and even then I might just put
it back)

Put in a line that reads:
192.168.1.57 mybox

(generally, "{IP} {hostname} [{host alias}]")

Just in case, check your "/etc/nsswitch.conf" file to make sure
that the "hosts:" line has "files" on it before anything else.

Reboot.

That's usually all I've ever had to do to fix the IP on a Sun box,
although it might be necessary to disable the DHCP client as well.
Try this first, and if it doesn't work, look in /etc/init.d/network
to find out how to shut off the DHCP client.

You could also create a runlevel script which alters the ip address
each time the machine gets booted (*remembers the trick to have a
hostname*)

I am not quite sure which files to edit, but I guess they're in
/etc/inet
However, you know your old IP-adress.
You could do: `cd /etc && grep -R "192.168.0.57" *`
Then you see all the files that have your old IP-address. Also you check
all that files and do:
`sed -i -e 's/192\.168\.0\.57/192\.168\.1\.57/g' /etc/*`

Or something like that.

/etc/nodename
/etc/hostname.<interface>
/etc/inet/hosts
/etc/inet/ipnodes

Those are all files you need to edit on Solaris 10.

Oh, the next sysadmin to get the machine would just love THAT.

One more --

/etc/nsswitch.conf

It's possible the "hosts:" line instructs to fetch the
IP from the NIS server, and only use the local files
if that fails.  There are two options here: the more
correct option of course is to fix the NIS server, but
if that's not possible, then set the "hosts:" line to
fetch from "files" before asking NIS (or NIS+).

Here=92s a quick HOWTO. Let=92s assume our network card is eri0, and we
want to create a virtual interface called eri0:1

Create the virtual interface:
# ifconfig eri0:1 plumb

Configure the virtual interface:
# ifconfig eri0:1 179.164.83.161 netmask 255.255.255.0 broadcast
179.164.83.255

Check to make sure it worked:

# ifconfig -a

lo0: flags=3D1000849 mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
eri0: flags=3D1000843 mtu 1500 index 2
inet 179.164.83.160 netmask ffffff00 broadcast 179.164.83.255
ether 0:3:ba:9:63:9b
eri0:1: flags=3D1000842 mtu 1500 index 2
inet 179.164.83.161 netmask ffffff00 broadcast 179.164.83.255

Finally bring up your new virtual interface:
# ifconfig eri0:1 up

To make it come up on start, this is important: Create /etc/
hostname.eri0:1 with below entries, make sure the hostname is in /etc/
hosts

hostname
addif <IP> netmask + broadcast + up
