SUMMARY: Moving a Solaris machine to a network

The answers arrived within minutes of the reception of my copy of my
query.

The answer is that the network interface needs to be "plumb"ed, and for
that to happen, the file /etc/hostname.interface (in this case
/etc/hostname.le0) must exist.

The procedure:
 place the hostname and IP address in /etc/hosts
 place hostname in /etc/hostname.le0
 reboot

(I went through a sys-unconfig/reboot cycle to get the name services set
up, but I guess that can also be done manually.)

I want to thank those that sent me answers to this problem, saving me a
full install:

(And thank you to all those whose messages get here after this is sent.)

Subject: Moving a Solaris machine to a network
Followup-To: junk

Hi;
I have a user with a SparcClassic who didn't want to have it connected to
the network when he bought it (quite some time ago). Now he wants to get
it connected, but I'm having extreme difficulties getting this going.

It was running Solaris 2.3. I tried sys-unconfig and rebooting, only to
get errors when trying to configure as a networked machine. Manual testing
gave me "ifconfig: SIOCGIFFLAGS: le0: no such interface" from ifconfig.

However, the network interface is recognised at boot, and I can use the
machine as a networked machine if I boot from CDROM. (I did try boot -r
without positive results as well.) Therefore the network interface is
functional.

This morning, I upgraded to Solaris 2.4. Everything went well, but when I
rebooted, the machine still refused to talk to the network. A sys-unconfig
/ reboot cycle doesn't even ask about the network interface anymore.

Now I understand that it's a configuration problem, but I can't figure out
what it might be. The machine seems to have the correct packages
installed, and there are no obvious kernel configuration problems.

My last option is a new OS installation, but I'm hesitant to do this, as
there are a couple of compiler products installed and a bunch of user
files on the system. I suppose that I can boot from CDROM and backup the
files over the network, but I want to ensure that I exhausted all options
before zapping the current system completely.

What can I do to resolve this?

Thanks in advance.
Ian.
