asked on Solaris 10 SPARC - change IP address for remote ssh
Hi,
I have a server that has Soalris 10 SPARC OS.
I can currently connect to it remotly using an IP address, but I want to change it to another IP address... what do I need to do? Pls let me know the commands...
Its the igb0. Is it just plumb? Shutdown necessary?
root@dp-# dladm show-dev
igb0 link: up speed: 1000 Mbps duplex: full
igb1 link: unknown speed: 1000 Mbps duplex: full
igb2 link: up speed: 1000 Mbps duplex: full
igb3 link: unknown speed: 0 Mbps duplex: unknown
usbecm0 link: up speed: 10 Mbps duplex: full
root@dp-# netstat -in

No need to do anything like plumbing?

ip address change with ifconfig does not require a reboot (Solaris even supports DHCP on cable plugged)
just that all open sockets are invalidated (wildcard listeners may or may not be affected) and you need to change startup files blindly without a way to verify

The point here was, he connect remotely. If unplumbed the interface, he will lost the connection and won't be able to login.

Tks for all replies.
I have some questions though:
1- Can I follow this procedure only to have the IP permentaly changed for the remote access using the ogb0 interface? This wouldnt need to reboot right?
Do this:
root@# ifconfig igb0 plumb
root@ # ifconfig igb0 1.1.1.2
root@ # ifconfig igb0 netmask 255.255.0.0
And then change the files mentioned in the last update?
2- OR I just update the files with the new IP and reboot the system?
============
Is this it? I mean is there any aditional step I need to run in order to have a new IP for the remote ssh (using the interface igb0) ?
Tks,
Joao

igb0 is up and running, plumb is not needed.
1) change files as mentioned
2) configure ILOM to meaningful IP configuration so you can change other addresses via it
3)run ifconfig from ilom (or gnu screen)
Or if in doubt reboot for 10-30min.

Tks again!
The ILOM interface already have an IP assigned to it and I dont want to change this one... but its not configured to remote access because of switch problems...
Sry for the newbie question.
So my question is: can I go to where the server is, connect via ethernet cable to the ILOM interface directly to my laptop, and using the IP that is configured to the ILOM can I connect via ssh to the server?
And once connected I can change the files mentioned (see below), and reboot the server so the ifconfig would be refreshed with the new IP value.
Would this work?
/etc/hosts
/etc/nodename
/etc/hostname.igb0
/etc/resolv.conf
/etc/net/ticlts/hosts
/etc/net/ticots/hosts
/etc/ticotsord/hosts
Tks,
Joao
