Yes, DNS is supported with 3.1 firmware. Perhaps it works only for the DTUs
having 3.1 or higher firmware.

Thanks

Hi Brad,

I connected my home DTU on the LAN this morning, fw was upgraded automagically 
:) I'm running the following release:

# utfwadm -P
System Version(P1)      3.1_32,REV=2005.08.24.08.55

Domain          Intf    Upgrade to
------------    ------  --------------------------
10.50.0.0       bge1    3.1_32,REV=2005.08.24.08.55

Could you confirm that DNS is supported with this one?

Regards,
Xavier

It would be also good to note that if your home router cannot be configured
to give the Option 49 parameter to DHCP clients, that using the DNS name
configuration option could also be done.
In fact DNS is much preferable, since the firmware can also be managed
via DNS, whereas with DHCP option 49 this is not possible - firmware must
be managed manually (e.g. via utfwload).

DTU's with 3.1 firmware ore capable of using DNS and TFTP to configure
themselves.

Basically the DTU's will look up sunray-config-servers in in the domain name
which they are given by your router. They will then TFTP their respective
parms file. This parms file contains the server(s) to connect to.

See the manpage for utfwadm or the admin guide for more details.

utfwload will report the firmware in your unit,
as will 'utquery -d <Sun Ray IP>' (this will also report
where your unit got its boot information).

utfwload can be used to upgrade firmware if desired.

Hi,
I'm busy to set up a Sunray client @ home.
My DHCP server give a x-display-manager attribute when the client boots
but nothing else...

I just read this comment:
(URL: http://www.sun.com/blueprints/0204/817-5490.pdf)

"DHCP option 49, the standard option of the X Window Display Manager,
identifies
130.146.59.5 as the address of a Sun Ray server. In the absence of
AltAuth and
Auth-Srvr vendor-specific options, the DTU tries to find a Sun Ray
server by
broadcasting on the local subnet. If the broadcasts evoke no response,
the DTU uses
the address supplied in t option of the X Window Display
Manager.provided that the
DTU contains firmware at Sun Ray Server Software 2.0 patch level
114880-01 or
greater."

How can I check my firmware release on the client? and upgrade if
necessary...

Thanks,
Xavier
