What am I doing wrong, I configure interfaces ce1,ce,2 and ce3 but when I reboot the server they lose the configuration and I have to reset them?

ifconfig ce1 plumb
ifconfig ce2 plumb
ifconfig ce1 155.216.13.72 netmask 255.255.255.240
ifconfig ce2 155.216.13.73 netmask 255.255.255.240
ifconfig ce1 up
ifconfig ce2 up

I created files these files

hostname.ce1
hostname.ce2
hostname.ce3

and added the ip's for the other interfaces in the host entry

hosts

::1     localhost
127.0.0.1       localhost
155.216.13.71   dixxa0accvce005 loghost
155.216.13.72   dixxa0accvce005a
155.216.13.73   dixxa0accvce004b
155.216.13.74   dixxa0accvce009

I think the disconnect here is that you need to put the hostname in the /etc/hostname.ce1,2,3 files. So, in your instance, put a different hostname in each file corresponding to the ip address you want assigned to that interface.

Maybe you need to add them to the start-up scripts, as I see no promise to save the settings in a file for future reference in the man page. I did see this:

 
                                                         The ifconfig  com-
       mand  must  be  used at boot time to define the network address of each
       interface present on a machine; it may also be used at a later time  to
       redefine  an  interface's  address or other operating parameters.

No registry in UNIX! :smiley:

This is not necessary in Solaris 10. Simply put the hostname that corresponds to the IP address you want on the interface into the proper /etc/hostname.<interface> file and you should be good.

# cat /etc/hostname.ce1
dixxa0accvce005
#

This is all you need.

thanks guys, you've been really helpful. Coming from windows this is pretty different then what I'm used to.
