Can't change ip address

[McQueen]

Hello all,

I'm trying to change the ip address of a V445. I've done the following :-

vi the following files and entered the correct details:-

/etc/hosts
/etc/defaultrouter
/etc/resolv.conf
/etc/netmasks

Then I did:-

ifconfig bge0 'new ipaddress' netmask 'new netmask' broadcast 'new broascast address'

But when I reboot the server and I do a ifconfig -a it still has the old ip address. I can't understand why?,
I've created an entry in s startup script to change to ip address on boot up to get round the problem but I would like to know why it doing it?.

Thanks for any help

Is this Solaris 10? If so, it appears you have to change /etc/inet/ipnodes too.

I want to be good, is that not enough?

Thanks Ken,

Changing the /etc/inet/ipnode worked and when I did a reboot it came back with the correct ip address, but it had the wrong netmask and broadcast address???.

What else have I missed this it the only Solaris10 box I have?.

Not sure (I don't have a 10 box to play with). Perhaps you need to issue the ifconfig again before rebooting to make the changes permanent?

Create a file in /etc called hostname.bge0
Add the hostname as a single entry.

i.e.
<hostname>:root> cat /etc/hostname.bge0
<hostname>

The /etc/hostname file will be referenced on boot and you should not need a scripted ifconfig to get this to work.

Check your entries in /etc/netmasks and /etc/defaultrouter.
/etc/netmasks, based on the standard class c, should show
<your ip network>.0 255.255.255.0


Hope this helps
