enable IPv6 after update to Solaris 10 6/06 on x86_64?
I upgraded my Sun W2100z workstation to Solaris 10 6/06 from 1/06 in early July. I remember that the updater asked me if I wanted to enable IPv6 support, and I thought I said "yes", but I'm not certain.
We're ready to begin testing IPv6 in our environment. I'm reading through the Sun Solaris 10 "System Administration Guide: IP Services", and wanted to try enabling inet6 on my workstation's built in (bge0) interface, following example 7-1 on page 149 of the IP Services
guide. Here's what I get:
#ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
bge0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet 134.129.NNN.NNN netmask ffffff00 broadcast 134.129.NNN.255
ether 0:a:e4:31:a2:a6
iprb0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
inet 172.17.110.23 netmask fffffe00 broadcast 172.17.111.255
ether 0:2:b3:15:6f:12
#ifconfig inet6 bge0 plumb up
ifconfig: bge0: bad address
#ifconfig inet6 iprb0 plumb up
ifconfig: iprb0: bad address
I'm guessing this means that ipv6 support is not loaded. That leads me to two questions:
- how can I tell, after the fact, if IPv6 support was loaded when a Solaris 10 box was
installed or updated? Is there a set of pkgs I should look for, or some other clue?
- assuming that IPv6 support was not selected at install/update time, how does one go
about getting it added to Solaris 10 after the install/update has finished? Load some
pkgs and reboot?
If this is covered in a guide or FAQ I've missed, please point me at it.
Thanks!

Wrong syntax. The interface should always be the first argument. (it's trying to interpret 'iprb0' as an IPv6 hostname and telling you that's a bad address).
[...]
CONFIGURING IPv6 INTERFACES
When an IPv6 physical interface is plumbed and configured
"up" with ifconfig, it is automatically assigned an IPv6
link-local address for which the last 64 bits are calculated
from the MAC address of the interface.
ifconfig le0 inet6 plumb up

It's not configured.

I don't believe there's any way not to install it.

Just ifconfig or set the /etc/hostname.<int>6 files the way you want.

Hey Darren! It seems you and I frequent the same haunts.
I was using that syntax because that's exactly what the "System Administration Guide: IP Services" for Solaris 10 shows in numerous places. I did eventually figure out that the guide is wrong in many places (it gets it correct in other places).

It's actually /etc/hostname6.<int>, and we tried that, multiple different ways. We tried
setting the (short) hostname in /etc/hostname6.bge0 and the IPv4 and IPv6 addresses that map to that hostname in /etc/inet/ipnodes, and that didn't work. At boot, I would get a
"Failed to configure IPv6 interface: bge0" message, and later would also see an error from "t_optmgmt". I could get a link-local address, but no other address.
I also tried setting the full ipv6 address (instead of the hostname) in /etc/hostname6.bge0, and that produced a similar result.
Using a combination of the man pages and the guide, we were eventually able to figure out how to get a particular persistent IPv6 address assigned to a particular interface (using auto-configuration to get the site prefix portion and "token" for the host id portion of the address - see chapter 7 page 159 of the aforementioned IP Services guide for Solaris 10).
Thanks,

Uh oh... I'm not sure which haunts you're referring to. :-) I have the feeling I should be remembering something.(ZFS? Networker?)

Ahh. Haven't used that guide. I just tried a few things on my machine and later found the man page agreed with me.

Ooops. Yep, that was the one thing I just typed in without going back to verify.

Hmm. I'm afraid I know a bit about what the scripts do around there, but not what IPv6 configuration files are supposed to look like.
Aside from the ifconfig error above, you're on your own!
(Glad you've got it working).
