Hi Michael,
do you tried to switch from multicast packets to a broadcast for the
group manager communication ?
I found many enviroments, where the multicast packets are not working
properly. You can disable the multicast packets in the
/etc/opt/SUNWut/auth.props file. You have to edit this on all nodes and
then restart the sunray services.

I'm revisiting an issue from a couple of weeks ago which I
still haven't been able to solve.
We have a FOG of two servers, we want to add a third. After
stepping through the instructions with no apparent problems,
it appears that there's some sort of communication problem
between the working servers and the new one.
All are on the same subnet, same ethernet segment. "arp -a"
on any of the three machines will show MAC addresses for the
other two.
On the new server, "dorchester", utgstatus looks good:
# utgstatus
host flags interface flags
128.135.119.0/24
------------- -------------------
dorchester TN 128.135.119.22 UA-
kenwood TN 128.135.119.58 UA-
blackstone TN 128.135.119.52 UA-
...but on the other two, dorchester reads as down:
# utgstatus
host flags interface flags
128.135.119.0/24
------------- -------------------
blackstone TN 128.135.119.52 UA-
dorchester TN 128.135.119.22 -A-
kenwood TN 128.135.119.58 UA-
If I do a "utrestart" on dorchester and wait a few seconds for
the refresh interval to pass, utgstatus will show dorchester
with the same status as the other two machines (UA-), but
after about sixty seconds, it goes back to "-A-" again.
If I "snoop tcp port 7011" on the new server, I see traffic
going back and forth between it and the other two systems:
blackstone.uchicago.edu -> dorchester TCP D=40896 S=7011
Push Ack=1135051640 Seq=1959152937 Len=14 Win=49640
dorchester -> blackstone.uchicago.edu TCP D=7011 S=40896
Push Ack=1959152951 Seq=1135051640 Len=14 Win=49640
dorchester -> kenwood.uchicago.edu TCP D=7011 S=40817 Push
Ack=3973154853 Seq=1134865131 Len=14 Win=49640
kenwood.uchicago.edu -> dorchester TCP D=40817 S=7011 Push
Ack=1134865145 Seq=3973154853 Len=14 Win=49640
dorchester -> kenwood.uchicago.edu TCP D=7011 S=40817
Ack=3973154867 Seq=1134865145 Len=0 Win=49640
blackstone.uchicago.edu -> dorchester TCP D=40896 S=7011
Ack=1135051654 Seq=1959152951 Len=0 Win=49640
"utreplica -l" looks good.
I don't find anything in the SUNWut/log/messages file that
looks like an error, but I might not know what to look for.
Any ideas for where to look next?
Thanks,
--Michael
