Hi,
Does it make sense to place DNS RR Load-balancing in front of a group of sunray
servers, to assist in connection aggregation?
I don't know about connection aggregation, but it's a good idea for load
balancing on the initial connection.
If you enter the FQDN LB address via the menu in the server list, the DTU
resolves the address and connects to the IP offered by the LB'er.
This is a list of hostnames and/or IP addresses, i.e., the server list.
It's equivalent to the servers= line in a .parms file.
However, I've replaced the AltAuth information to reflect the DNS alias for the
LB in my DHCP scope and I receive 27B.
Are you saying you set it to a host name? AltAuth is a list of IP
addresses, not a list of hostnames. I'm surprised your DHCP server let
you set it that way. From dhtadm -P:
AltAuth Symbol Vendor=SUNW.NewT.SUNW,35,IP,1,0
Having read the SRSS 3.1 entry for provisioning on ThinkThin, I noticed that it
might be down to something DNS resolution related.
I doubt it. It sounds as if you've misconfigured AltAuth.
So my questions are I guess: 1) Are FQDN's supported via DHCP? 2) Does the DTU
have to be the same DNS domain as the FQDN entered?
> 3) Has anyone else seen this before?
FQDN's for servers are not directly supported by DHCP. However, the
TFTPsrvN option as a single FQDN is supported. From there, you can put a
servers= line in the .parms file. You can also use the default
"sunray-servers" name in the local DNS domain. The DTU does not have to
be in the same DNS domain as the FQDN entered. In fact, the normal
configuration for the DNS domain name is to set it to the one in which
the servers reside, so the names don't have to be fully qualified. Any
hostname for the Sun Ray itself is irrelevant.
